About Mosaic Government Money Market

Mosaic Government Money Market (the "Trust") is a diversified open-end 
management investment company, commonly known as a money market fund.  
The Trust was organized as a Massachusetts business trust under a 
Declaration of Trust dated February 14, 1979, then known as Government 
Investors Trust.  The Trust is managed by Madison Mosaic, a wholly-owned 
subsidiary of Madison Investment Advisors, Inc. (the "Advisor"), of the 
same address as the Trust.  Only one series of the Trust's shares is 
currently authorized.

Expense Summary

The purpose of this table is to assist investors in understanding the 
various costs and expenses that an investor will bear directly or 
indirectly (see also "Management of the Trust" below).

Shareholder Transaction Expenses

     Maximum Sales Load Imposed on Purchases          None
     Redemption Fee                                   None
     Exchange Fee                                     None

Annual Fund Operating Expenses (as a percentage of average net assets)

     Management Fee                                  0.50%
     Other Expenses*                                 0.40%

     Total Fund Operating Expenses                   0.90%



Example:                            1 Year     3 Years     5 Years     10 Years

You would pay the following expenses 
on a $1,000 investment, assuming 
(1) a five percent annual return and 
(2) redemption at the end of each 
time period:                           $9         $29         $50         $111


The hypothetical example shown above is based on the expense levels 
listed under the caption "Annual Fund Operating Expenses" and is 
intended to provide the investor with an understanding of the level of 
expenses that might be incurred in the future.  The five percent return 
used in the example is arbitrary and is for illustrative purposes only.  
It should not be considered representative of the Trust's past or future 
performance, nor should the expenses in the example be considered 
representative of future expenses, which may actually be greater or less 
than those shown.  Additional fees and transaction charges described 
elsewhere in this prospectus, if applicable, will increase the level of 
expenses that can be incurred (fees for certain wire transfers, stop 
payments on checks, bounced investment checks, and retirement plans are 
described on pages 8-11).


Financial Highlights

The financial highlights data for a share outstanding and other 
performance information for the six-month fiscal year ended September 
30, 1997 appearing below is derived from the financial statements 
audited by Deloitte & Touche LLP, independent auditors, whose report 
appears in the Annual Report to Shareholders.  This report is 
incorporated by reference in the Statement of Additional Information and

financial statements audited by Ernst & Young LLP.  The Trust 
experienced no net gains or losses on securities and provided no 
distributions from capital gains or returns of capital for the fiscal 
years shown below.

Investment Objective

The investment objective of the Trust is to obtain the highest possible 
current income, consistent with the relative safety of U.S. Government 
securities and with providing liquidity and price stability to 
shareholders' investments in the Trust.  Considerations of relative 
safety, liquidity and price stability limit the Trust's investments to 
shorter-term U.S. Government securities which may not yield as high a 
level of current income as is normally available from longer-term or 
lower-rated securities.  The Trust's investment objective may be changed 
without shareholder approval; however, shareholders will receive prior 
written notice of any material change.  There is no assurance that the 
Trust's investment objective will be achieved.

Investment Policies

The Trust's fundamental investment policies, which may not be changed 
without a shareholder vote, limit its investments to securities issued 
or guaranteed by the U.S. Government, its agencies or instrumentalities.  
The Trust expects that a substantial portion of its assets will be 
invested in repurchase agreements collateralized by U.S. Government 
securities.  The Trust intends normally to hold portfolio securities to 
maturity; historically, securities issued or guaranteed by the U.S.  
Government or its agencies or instrumentalities have involved little 
risk to principal and interest if held to maturity.  

The Trust will limit purchases of investments to securities having a 
maximum effective maturity of 13 months or less.  The Trust will not 
purchase any investment which would, at the time of purchase, cause the 
average effective maturity of the Trust to exceed 90 days.  As used in 
this Prospectus, the term "effective maturity" means either the actual 
time between purchase and the stated maturity date of the investment, 
the time between its scheduled interest rate adjustment dates, or the 
time between its purchase settlement and its future resale arranged at 
the time of purchase under fixed terms.  The Trust's portfolio will be 
managed in conformity with regulations of the Securities and Exchange 
Commission applicable to funds seeking to maintain a constant share 
price of $1.00.  The Trust will not invest more than 10 percent of its 
total assets in securities which cannot be liquidated in seven days.  
The Trust normally expects to hold investments to maturity, except to 
the extent liquidity requirements indicate otherwise.

U.S. Government Securities.  U.S. Government securities include a 
variety of securities which are issued or guaranteed by the U.S. 
Treasury, various agencies of the federal government and various 
instrumentalities which have been established or sponsored by the U.S. 
Government, and certain interests in the foregoing types of securities.  
Treasury securities include notes, bills and bonds.  Obligations of the 
Government National Mortgage Association, the Federal Home Loan Banks, 
the Federal Farm Credit System, the Federal Home Loan Mortgage 
Corporation, the Federal National Mortgage Association, the Small 
Business Administration and the Student Loan Marketing Association are 
also considered U.S. Government securities.  Except for Treasury 
securities, these obligations may or may not be backed by the "full 
faith and credit" of the United States.

Some federal agencies have authority to borrow from the U.S. Treasury 
while others do not.  In the case of securities not backed by the full 
faith and credit of the United States, the investor must look 
principally to the agency issuing or guaranteeing the obligation for 
ultimate repayment, and may not be able to assert a claim against the 
United States itself in the event the agency or instrumentality does not 
meet its commitments.

Specialized Investment Techniques

To achieve its investment objective, the Trust may use certain 
specialized investment techniques, including investment in specialized 
kinds of government agency securities, investment in "floating rate" 
government securities, use of repurchase agreement transactions, 
investment in matched purchase/sale transactions and investments 
purchased for forward delivery.  These techniques may involve certain 
risks, some of which are summarized below, and discussed further in the 
Statement of Additional Information.

Certain specialized government agency securities may provide higher 
yields than are available from more common types of government-backed 
investments.  However, such specialized investments may be available 
from a few sources, in limited amounts, or only in very large 
denominations; they may also require special capabilities in portfolio 
servicing and in legal matters relating to government guarantees.  Such 
securities may have limited marketability, which might make it difficult 
for the Trust to dispose of them advantageously; accordingly, the Trust 
intends normally to hold such securities to maturity or pursuant to 
repurchase agreements.

"Floating rate" government agency securities pay an interest rate which 
is adjusted (i.e., "floats") at regular intervals in a fixed 
relationship to a published interest rate such as the "prime" rate of a 
given bank.  Such securities may offer higher yields than are available 
from short-term securities and may be less susceptible to market value 
fluctuations than securities of longer stated maturities which do not 
float.  The stated maturities of floating rate securities, which could 
be as long as 30 years, may limit their investment flexibility.  Such 
securities may be available only in large denominations, may require 
specialized servicing and accounting capabilities, and may have limited 
marketability, which might make it difficult for the Trust to dispose of 
them advantageously.

Repurchase agreements involve the sale of securities to the Trust by a 
financial institution or securities dealer, simultaneous with an 
agreement by that institution to repurchase the same securities at the 
same price, plus interest, at a later date.  The Trust will limit 
repurchase agreement transactions to those financial institutions and 
securities dealers who are deemed creditworthy pursuant to guidelines 
adopted by the Trust's Board of Trustees.  The Advisor will follow a 
procedure designed to ensure that all repurchase agreements acquired by 
the Trust are always at least 100 percent collateralized as to principal 
and interest.  When investing in repurchase agreements, the Trust relies 
on the other party to complete the transaction on the scheduled date by 
repurchasing the securities.  Should the other party fail to do so, the 
Trust would end up holding securities it did not intend to own.  Were it 
to sell such securities, the Trust might incur a loss.  In the event of 
insolvency or bankruptcy of the other party to a repurchase agreement, 
the Trust could encounter difficulties and might incur losses upon the 
exercise of its rights under the repurchase agreement.

Investment Considerations

The Trust's investment policies may involve certain risks.  For example, 
the market value of the fixed income securities in which the Trust 
invests will tend to decline as prevailing interest rates rise and 
increase as prevailing interest rates fall.  The magnitude of this 
change increases with the maturity of portfolio securities.  The Trust 
may invest in "floating rate" government agency securities, in 
repurchase agreements, in matched purchase/sale transactions and in 
investments purchased for forward delivery, all of which may involve 
certain risks; see "Specialized Investment Techniques" above and in the 
Statement of Additional Information.

Management of the Trust

The Trustees.  Under the terms of the Declaration of Trust, which is 
governed by the laws of the Commonwealth of Massachusetts, the Trustees 
are ultimately responsible for the conduct of the Trust's affairs.  They 
serve indefinite terms of unlimited duration and they appoint their own 
successors, provided that always at least two-thirds of the Trustees 
have been elected by shareholders.  The Declaration of Trust provides 
that a Trustee may be removed at any special meeting of shareholders by 
a vote of two-thirds of the Trust's outstanding shares.
   
The Advisor.  Madison Mosaic (previously known as Bankers Finance 
Advisors, LLC) is a wholly-owned subsidiary of Madison Investment 
    
Advisors, Inc., 6411 Mineral Point Road, Madison, Wisconsin ("Madison").  
Madison Mosaic administers approximately $200 million in assets and 
manages the Mosaic family of mutual funds, which includes stock, bond 
and money market portfolios.  Madison, a registered investment advisory 
firm for over 24 years, provides professional portfolio management 
services to a number of clients, including stock and bond mutual funds, 
and has approximately $3 billion under management.  The Advisor is 
responsible for the day-to-day administration of the Trust's activities.

The Advisor is controlled by Madison.  The Advisor purchased the 
investment management assets of Bankers Finance Investment Management 
Corp., the previous adviser to the Trust, effective July 31, 1996.  The 
Advisor has the same address as the Trust.

Compensation.  For its services under its Investment Advisory Agreement 
with the Trust, the Advisor receives a fee, payable monthly, calculated 
as 1/2 percent per annum of the average daily net assets of the Trust.  
The Advisor may, in turn, compensate certain financial organizations for 
services resulting in shareholder purchases of Trust shares.
   
Distributor.  GIT Investment Services, Inc.  of the same address as the 
Trust acts as the Trust's distributor for marketing the Trust's shares.  
Purchases and redemptions of Trust shares are accomplished by the Trust.  
The Trust will provide shareholders with transaction confirmations and 
quarterly statements.

Services Agreement.  Under a separate Services Agreement with the Trust, 
the Advisor provides certain operational and other support services for 
which it receives a fixed fee intended to be at or below the cost of 
providing such services, calculated as a percentage of the average daily 
net assets of the Trust.  As of the date of this prospectus, such fee is 
0.38%.  Such fee is subject to review and approval at least annually by 
the Trustees.  Such fee pays for the Trust's expenses, including the 
costs of the following: shareholder services; legal, custodian and audit 
fees; trade association memberships; accounting; certain Trustees' fees 
and expenses; fees for registering the Trust's shares; the preparation 
of prospectuses, proxy materials and reports to shareholders; and the 
expense of holding shareholder meetings.  
    
Transfer and Dividend Paying Agent.  The Trust acts as its own transfer 
agent and dividend paying agent.
       

The Trust and Its Shares

Under the terms of the Declaration of Trust, the Trustees may issue an 
unlimited number of whole and fractional shares of beneficial interest 
without par value for each series of shares they have authorized.  All 
shares issued will be fully paid and nonassessable and will have no 
preemptive or conversion rights.  Under Massachusetts law, the 
shareholders, under certain circumstances, may be held personally liable 
for the Trust's obligations.  The Declaration of Trust, however, 
provides indemnification out of Trust property of any shareholder held 
personally liable for obligations of the Trust.

Only one series of the Trust's shares is currently authorized.  Each 
share has one vote and fractional shares have fractional votes.  Except 
as otherwise required by applicable regulations, any matter submitted to 
a shareholder vote will be voted upon by all shareholders without regard 
to series or class.  For matters where the interests of separate series 
or classes are not identical, the question will be voted on separately 
by each affected series or class.  Voting is not cumulative.

The Trust does not intend to have regular shareholder meetings.  
Shareholder inquiries can be made to the offices of the Trust at the 
address on the cover of this Prospectus.

Dividends

The Trust's net income is declared as dividends each business day.  
Dividends are paid in the form of additional shares credited to investor 
accounts at the end of each calendar month, unless a shareholder elects 
in writing to receive a monthly dividend payment by check or direct 
deposit.  Any net realized capital gains will be distributed at least 
annually.

Performance Information

From time to time, the Trust advertises its yield and effective yield.  
Both figures are based on historical data and are not intended to 
indicate future performance.

For advertising purposes, the yield is calculated according to a 
standard formula prescribed by the Securities and Exchange Commission.  
This formula divides the net income earned on one share during a given 
seven-day period by the initial value of that share (normally $1.00), 
and expresses the result as an annualized percentage.

The Trust's "effective yield" is calculated in a similar manner, except 
that the net income earned during a seven-day period is assumed to be 
reinvested at the same rate over a full year.  This calculation results 
in a slightly higher yield figure which shows the effect of compounding.

The Trust may also cite the ranking or performance of its Portfolio as 
reported in the public media or by independent performance measurement 
firms.  Further information on the methods used to calculate the Trust's 
yield may be found in the Trust's Statement of Additional Information.

Taxes

Federal

For federal income tax purposes, the Trust intends to maintain its 
status under Subchapter M of the Internal Revenue Code (the "Code") as a 
regulated investment company.  It does this by distributing to 
shareholders 100% of its net income and net capital gains, if any, by 
the end of its fiscal year.  The Code also requires the Trust to 
distribute at least 98% of its net income and capital gains realized 
from the sale of investments by calendar year-end in order to avoid a 4% 
excise tax. 
   
Although the Trust does not invest in a manner that would 
normally result in any capital gains, the capital gain distribution must 
    
be determined as of October 31 each year.  Capital gain distributions, 
if any, are taxable to the shareholder.  The Trust will send 
shareholders an annual notice of dividends and other distributions paid 
during the year.

State and Local

At the state and local level, dividend income and capital gains are 
generally considered taxable income.  Interest on certain U.S.  
Government securities held by the Trust would be exempt from state and 
local income taxes if held directly by the shareholder.
   
The Trust is generally permitted to "pass-through" this exemption to 
shareholders.  The Trust will send shareholders an annual notice of the 
percentage of  U.S.  Government securities which are exempt from 
state and local income taxes.
    
Certification of Tax Identification Number

Shareholders who fail to provide a valid social security or tax 
identification number may be subject to federal withholding at a rate of 
31% of dividends and capital gain distributions.  Investors are advised 
to retain all statements received from the Trust and to maintain 
accurate records of their investments.

Net Asset Value

The net asset value per share of the Trust is calculated at the close of 
the New York Stock Exchange each day it is open for trading.  Net asset 
value per share is determined by adding the value of all securities and 
other assets, subtracting liabilities and dividing the result by the 
total number of the Trust's outstanding shares.  The Trust's securities 
are valued according to the "amortized cost" method, which is intended 
to stabilize the share price at $1.00.

Shareholder Account Transactions 

Please call a Mosaic Account Executive if you have any questions.  Our 
local number in the Washington, DC area is (703) 528-6500 and our toll-
free nationwide number is (888) 670-3600.

Confirmations and Statements

Daily Transaction Confirmation.  All purchases and redemptions are 
confirmed in writing with a transaction confirmation.  Transaction 
confirmations are usually mailed within a day or two after the 
transaction is posted to the account.

Quarterly Statement.  Quarterly statements are mailed at the end of each 
calendar quarter.  The statements reflect account activity for the most 
recent quarter.  At the end of the calendar year, the statement will 
reflect account activity for the entire year.

It is strongly recommended that shareholders retain all daily 
transaction confirmations until they receive their quarterly statements.  
Likewise, shareholders should retain all of the quarterly statements 
until they receive the year-end statement showing the activity for the 
entire year.

Changes to an Account

To make any changes to an account, it is recommended that shareholders 
call an Account Executive to discuss the changes to be made and inquire 
about any necessary documentation.  Though some changes may be made by 
phone, generally, in order to make any changes to an account, Mosaic may 
require a written request signed by all of the shareholders with their 
signatures guaranteed.

Telephone Transactions.  The options to initiate exchanges and certain 
redemptions and to obtain account balance information by telephone are 
available automatically to all shareholders.  Mosaic will employ 
reasonable security procedures to confirm that instructions communicated 
by telephone are genuine; and if it does not, it may be liable for 
losses due to unauthorized or fraudulent transactions.  These procedures 
can include, among other things, requiring one or more forms of personal 
identification prior to acting upon telephone instructions, providing 
written confirmations and recording all telephone transactions.  Certain 
transactions, including account registration changes, must be authorized 
in writing.

Certificates.  Certificates will not be issued to represent shares in 
the Trust.

Arlington, VA 22209-3108

By Wire

Please call Mosaic before money is wired to ensure proper and timely 
credit.

When a new account is opened by wire, the shareholder is required to 
submit a signed application promptly thereafter.  Payment of redemption 
proceeds is not permitted until a signed application is received in 
proper form by Mosaic.  Please wire money to:

Star Bank, NA
Cinti/Trust
ABA # 0420-0001-3
Credit Mosaic Acct # 48038-8883
(Shareholder name and account number)

Wire Fee.  There may be a charge of $6.00 for processing incoming wires 
of less than $1,000.

By Exchange

Shareholders may open a new account by exchange from an existing account 
when the account registration and tax identification number will remain 
the same.  A new account application is required only when the account 
registration or tax identification number will differ from that on the 
application for the original account.  Exchanges may only be made into 
funds that are sold in the shareholder's state of residence.

How to Purchase Additional Shares

Purchase Price.  Share prices (net asset values) are determined every 
day that the NY Stock Exchange is open.  Purchases are priced at the 
next share price determined after the purchase request is received in 
proper form by Mosaic.

Purchases and Uncollected Funds.  To protect shareholders from loss or 
dilution resulting from deposit items that are returned unpaid, the 
proceeds of any redemption may be delayed 10 days or more until it can 
be determined that the check or other deposit item (including purchases 
by Electronic Funds Transfer "EFT") used for purchase of the shares has 
cleared.  Such deposit items are considered "uncollected," until Mosaic 
has determined that they have actually been paid by the bank on which 
they were drawn.  Purchases made by federal funds wire or U.S.  Treasury 
check are considered collected when received and not subject to the 10 
day hold.  All purchases earn dividends from the day after the day of 
credit to a shareholder's account, even while not collected.

By Check

Subsequent investments may be made for $50 or more.  Please make check 
payable to Mosaic Funds and mail it along with an investment slip or an 
indication as to which fund and account it should be credited.

Mosaic Funds
PO Box 640393
Cincinnati, OH 45264-0393

By Wire

Shareholders should call Mosaic before the money is wired to ensure 
proper and timely credit.

Please wire money to:

Star Bank, NA
Cinti/Trust
ABA # 0420-0001-3
Credit Mosaic Acct # 48038-8883
(Shareholder name and account number)

Wire Fee.  There may be a charge of $6.00 for processing incoming wires 
of less than $1,000.

By Automatic Investment Plan

Shareholders may elect to have an automatic investment plan whereby 
Mosaic will automatically initiate a credit to their Mosaic account and 
debit the bank account they designate each month.  The automatic 
investment is processed as an electronic funds transfer (EFT).  To 
establish an automatic investment plan, complete the appropriate section 
of the application or call an Account Executive for information.  The 
minimum monthly amount for an EFT is $100.  Shareholders may change the 
amount or discontinue the automatic investment plan any time.

How to Redeem Shares

Redemption Price.  Share prices (net asset values) are determined every 
day that the NY Stock Exchange is open.  Redemptions are priced at the 
next share price determined after the redemption request is received in 
proper form by Mosaic.

Signature Guarantees.  To protect shareholder investments, Mosaic 
requires signature guarantees for certain redemptions.  A signature 
guarantee helps Mosaic ensure the identity of the authorized 
shareholder(s).  Shareholders who anticipate the need to transact large 
amounts of money are encouraged to establish pre-authorized bank wire 
instructions on their account.  Redemptions by wire to a pre-authorized 
bank and account may be in any amount and do not require a signature 
guarantee.  Pre-authorized bank wire instructions can be established by 
completing the appropriate section of a new application or by calling an 
Account Executive to inquire about any necessary documents.  A signature 
guarantee may be required to add or change bank wire instruction on an 
account.  A signature guarantee is required for any redemption when (1) 
the proceeds are to be greater than $50,000 (unless proceeds are being 
wired to a pre-authorized bank and account), (2) the proceeds are to be 
delivered to someone other than the shareholder of record, (3) the 
proceeds are to be delivered to an address other than the address of 
record, or (4) there has been any change to the registration or account 
privilege within the last 15 days.  Mosaic accepts signature guarantees 
from banks with FDIC insurance, certain credit unions, trust companies, 
and members of a domestic stock exchange.  A guarantee from a notary 
public is not an acceptable signature guarantee.

Redemptions and Uncollected Funds.  To protect shareholders from loss or 
dilution resulting from deposit items that are returned unpaid, the 
proceeds of any redemption may be delayed 10 days or more until it can 
be determined that the check or other deposit item (including EFT) used 
for purchase of the shares has cleared.  Such deposited items are 
considered "uncollected," until Mosaic has determined that they have 
actually been paid by the bank on which they were drawn.  Purchases made 
with cash, federal funds wire or U.S. Treasury check are considered 
collected when received and not subject to the 10 day hold.  

By Telephone or By Mail

Upon request by telephone or in writing, a redemption check up to 
$50,000 may be sent to the shareholder and address of record only.  A 
redemption request for more than $50,000 or for proceeds to be sent to 
anyone or anywhere other than the shareholder and address of record, 
must be made in writing, signed by all shareholders with their 
signatures guaranteed.  See section Signature Guarantees above.  
Redemption requests in proper form received by mail and telephone are 
normally processed within one business day.

Stop Payment Fee.  To stop payment on a check issued by Mosaic, call our 
Shareholder Service department.  Normally, the Fund charges a fee of 
$28.00, or the cost of stop payment, if greater, for stop payment 
requests on a check issued by Mosaic on behalf of a shareholder.  
Certain documents may be required before such a request can be 
processed.

By Wire

With one business day's notice, funds can be sent by wire transfer to 
the bank and account designated on the account application or by 
subsequent written authorization.  Shareholders who anticipate the need 
to transact large amounts of money are encouraged to establish pre-
authorized bank wire instructions on their account.  Redemptions by wire 
to a pre-authorized bank and account may be in any amount and do not 
require a signature guarantee.  Pre-authorized bank wire instructions 
can be established by completing the appropriate section of a new 
application or by calling an Account Executive to inquire about any 
necessary documents.  A signature guarantee may be required to add or 
change bank wire instruction on an account.  Redemption by wires can be 
arranged by calling the telephone numbers on the cover of this 
prospectus.  Requests for wire transfer must be made by 4:00 p.m.  
Eastern time the day before the wire will be sent.

Wire Fee.  There will be a $10 fee for redemptions by wire to domestic 
banks.  Wire transfers sent to a foreign bank for any amount will be 
processed for a fee of $30 or the cost of the wire if greater.

By Exchange

Shareholders may redeem shares from one Mosaic account and concurrently 
invest the proceeds in another Mosaic account by telephone when the 
account registration and tax identification number remain the same.  
There is no charge for this service.

By Customer Check

A shareholder who has requested check writing privileges and submitted a 
signature card may write checks in any amount payable to anyone.

A confirmation statement showing the amount and number of each check 
written is sent to the shareholder.  Mosaic does not return canceled 
checks, but will provide copies of specifically requested checks.  A fee 
of $1.00 per copy is charged for frequent requests or a request for 
numerous copies.

Stop Payment Fee.  To stop payment on a customer check that you have 
written, call an Account Executive.  Mosaic will honor stop payment 
requests on unpaid customer checks written by shareholders for a fee of 
$5.00.  Oral stop payment requests are effective for 14 calendar days, 
at which time they will be canceled unless confirmed in writing.  
Written stop payment orders are effective for six months and may be 
extended by written request for another six months.

Ordering Customer Checks.  When you complete a signature card for check 
writing privileges an initial supply of preprinted checks will be sent 
free of charge.  The cost of check reorders and of printing special 
checks will be charged to the shareholder's account.

By Systematic Withdrawal Plan

Shareholders may elect to have a systematic withdrawal plan whereby 
Mosaic will automatically redeem shares in their Mosaic account and send 
proceeds to a designated recipient.  To establish a systematic 
withdrawal plan, complete the appropriate section of the application or 
call an Account Executive for information.  The minimum amount for a 
systematic withdrawal is $100.  Shareholders may change the amount or 
discontinue the systematic withdrawal plan anytime.

Electronic Funds Transfer Systematic Withdrawal.  A systematic 
withdrawal can be processed as an electronic funds transfer, commonly 
known as EFT, to credit a bank account or financial institution.  

Check Systematic Withdrawal.  Or it can be processed as a check which is 
mailed to anyone designated by the shareholder

How to Close an Account

To close an account, shareholders should call an Account Executive and 
request that the account be closed.  Shareholders cannot close their 
account by writing a check.  When an account is closed, shares will be 
redeemed at the next determined net asset value.  An account may be 
closed by telephone, wire transfer or by mail as explained above in the 
section "How To Redeem Shares."

Other Fees and Services

Returned Investment Check Fee.  Shareholders will be charged (by 
redemption of shares) $10.00 for items deposited for investment that are 
returned unpaid for any reason.

Minimum Balance.  Mosaic reserves the right to involuntarily redeem 
accounts with balances of less than $700.  Prior to closing any such 
account, the shareholder will be given 30 days written notice, during 
which time the shareholder may increase the balance to avoid having the 
account closed.

Other Fees.  Mosaic reserves the right to impose additional charges, 
upon 30 days written notice, to cover the costs of unusual transactions.  
Services for which charges could be imposed include, but are not limited 
to, processing items sent for special collection, international wire 
transfers, research and processes for retrieval of documents or copies 
of documents.

Retirement Plans

IRAs

Individual Retirement Accounts ("IRAs") and Roth IRAs may be opened with 
a reduced minimum investment of $500.  Even though they may be 
nondeductible or partially deductible, IRA contributions up to the 
allowable annual limits may be made, and the earnings on such 
contributions will accumulate tax-free.  

Annual IRA Fee.  Mosaic currently charges an annual fee of $12 per 
shareholder (not per IRA account) invested in an IRA or Roth IRA at 
Mosaic.  This fee may be prepaid by the shareholder.  A separate 
application is required for IRA accounts.
   
Education IRAs

Education IRAs may be established with a reduced minimum investment of 
$100 as long as the shareholder establishes and maintains an "Education 
IRA Plus" automatic investment plan of at least $100 monthly.  The 
"Education IRA Plus" will be invested to reach the annual $500 Education 
IRA limit, with the remainder invested in an account established by the 
parent or guardian of the Education IRA beneficiary.  

Education IRA Fee.  Mosaic does not charge an annual fee on Education 
IRA Plus accounts that have an active automatic investment plan of at 
least $100 monthly, or on Education IRA accounts of $5,000 or greater.  
All other Education IRA accounts will be charged an annual fee of $12 
per shareholder (not per Education IRA account).  This fee may be 
prepaid by the shareholder.
    
Keogh Plans

Mosaic also offers Keogh (or H.R.  10) plans for self-employed 
individuals and their employees, which enable them to obtain tax-
sheltered retirement benefits similar to those available to employees 
covered by other qualified retirement plans.

Annual Keogh Fee.  Currently Mosaic charges an annual fee of $12 per 
shareholder (not per Keogh account) invested in a Keogh at Mosaic.

Mosaic also offers SEP IRAs, SIMPLEs, 401(k) and 403(b) retirement 
plans.  Call Mosaic's shareholder service department for further 
information on the retirement plans available through Mosaic, including 
minimum investments.

Statement of Additional Information.

INTRODUCTORY INFORMATION
   
Mosaic Government Money Market (the "Trust") is an open-end diversified 
management investment company which invests solely in short-term debt 
securities issued or guaranteed by agencies and intrumentalities of the 
U.S. Government.  It may use a variety of investment techniques with the 
objective of providing as high a yield as is available from U.S. 
Government securities and the investment quality associated with these 
securities (see "Supplemental Investment Policies").  Prior to May 12, 
1997, the Trust was known as Government Investors Trust.
    
SUPPLEMENTAL INVESTMENT POLICIES

The Trust seeks to achieve its investment objective through investment 
in securities issued or guaranteed by the U.S. Government, its agencies 
or instrumentalities and in participation interests in and repurchase 
agreements based on such securities.  The investment objective of the 
Trust is described in the Prospectus (see "Investment Objective").  
Reference should also be made to the Prospectus for general information 
concerning the Trust's investment policies (see "Investment Policies").  
Unless described herein or in the Prospectus, the Trust will not invest 
in "derivative" securities.  Any deviation from this policy must be 
approved by the Trustees in advance.

Specialized Investment Techniques.  In order to achieve its investment 
objective, the Trust may use, when the Advisor deems appropriate, 
certain specialized investment techniques.  Such specialized investment 
techniques principally include those identified in the Prospectus (see 
"Investment Policies"), which are described more fully below:

1.  Investments in Specialized Kinds of Government Agency Securities.  
These agency securities often provide higher yields than are available 
from more common types of Government-backed investments.  However, such 
specialized investments may only be available from a few sources, in 
limited amounts, or only in very large denominations; they may also 
require specialized capability in portfolio servicing and in legal 
matters related to Government guarantees.  While frequently offering 
attractive yields, the limited-activity markets of many of these 
securities means that if the Trust were forced to liquidate any of them 
it might not be able to do so advantageously; accordingly, the Trust 
intends to normally hold such securities to maturity or pursuant to 
repurchase agreements.

2.  Investment in "Floating Rate" Government Agency Securities.  These 
Government agency securities may offer particular advantages towards the 
achievement of the objectives of the Trust by providing for an interest 
rate which is adjusted (i.e., "floats") at regular intervals according 
to some published interest rate.  Such securities frequently offer 
higher yields than are available on short-term securities but less risk 
of market value fluctuations than securities of longer maturities which 
do not float.  Interest rates, and thus income to the Trust, on these 
securities will normally float downward when interest rates are falling 
and float upward when their reference rates of interest rise.  
Generally, such investments float in relation to the "prime" interest 
rate of New York or other money center banks and often are adjusted 
upward or downward periodically, although some such securities float in 
relationship to other published interest rates or at more or less 
frequent intervals.  These floating rate securities may have stated 
maturities of up to 30 years, although 10-year stated maturities are 
more typical.  Floating rate securities may be comparable in some 
respects to short-term securities, but their longer stated maturities 
reduce investment flexibility, making them less attractive than short-
term securities to some investors.

3.  Repurchase Agreement Transactions.  A repurchase agreement involves 
the acquisition of securities from a financial institution, such as a 
bank or securities dealer, with the right to resell the same securities 
to the financial institution on a future date at a fixed price.  
Repurchase agreements are a highly flexible medium of investment in that 
they may be for very short periods, including, frequently, maturities of 
only one day.  Under the Investment Company Act of 1940 repurchase 
agreements are considered loans and the securities involved may be 
viewed as collateral.  It is the Trust's policy to limit the financial 
institutions with which it engages in repurchase agreements to banks, 
savings and loan associations and securities dealers meeting financial 
responsibility standards prescribed in guidelines adopted by the 
Trustees.

When investing in repurchase agreements, the Trust could be subject to 
the risk that the other party may not complete the scheduled repurchase 
and the Trust would then be left holding securities it did not expect to 
retain.  If those securities decline in price to a value less than the 
amount due at the scheduled time of repurchase, then the Trust could 
suffer a loss of principal or interest.  The Advisor will follow 
procedures designed to assure that repurchase agreements acquired by the 
Trust are always at least 100% collateralized as to principal and 
interest.  It is the Trust's policy to require delivery of repurchase 
agreement collateral to its Custodian or (in the case of book-entry 
securities held by the Federal Reserve System) that such collateral is 
registered in the Custodian's name or in negotiable form.  In the event 
of insolvency or bankruptcy of the other party to a repurchase 
agreement, the Trust could encounter restrictions on the exercise of its 
rights under the repurchase agreement.

To the extent the Trust requires cash to meet redemption requests and 
determines that it would not be advantageous to sell portfolio 
securities to meet those requests, then it may sell its portfolio 
securities to another investor with a simultaneous agreement to 
repurchase them.  Such a transaction is commonly called a "reverse 
repurchase agreement." It would have the practical effect of 
constituting a loan to the Trust, the proceeds of which would be used to 
meet cash requirements from redemption requests.  During the period of 
any reverse repurchase agreement, the Trust would recognize fluctuations 
in value of the underlying securities to the same extent as if those 
securities were held by the Trust outright.  If the Trust engages in 
reverse repurchase agreement transactions, it will maintain in a 
segregated account designated Government securities which are liquid or 
mature prior to the scheduled repurchase and cash sufficient in 
aggregate value to provide adequate funds for completion of the 
repurchase.  It is the Trust's current operating policy not to engage in 
reverse repurchase agreements except for purposes of meeting redemption 
requests.  The Trust will not enter into any reverse repurchase 
agreement, if as a result, reverse repurchase agreements in the 
aggregate would exceed 10% of the Trust's total assets.

4.  Investment in Matched Purchase/Sale Transactions.  The Trust may 
invest by means of matched purchase/sale transactions containing two 
elements: the purchase of U.S. Government securities and a simultaneous 
sale of those securities by means of a future delivery contract at a 
fixed price for later delivery to a different institution (securities 
dealer, bank, etc.).  During the interval between the actual dates they 
are bought and sold, the securities will be held by a custodian of the 
Trust.  The transactions are thus self-liquidating and produce a known 
yield, similar to a repurchase agreement; this yield is comprised of the 
interest earned on the securities while they are held plus the price 
differential between the purchase and sale.  The sale price may be more 
or less than the price at which the securities could otherwise be sold 
on the day delivery is due.  These arbitrage transactions may be 
attractive if market conditions create opportunities for higher yields 
than on repurchase agreements.  It is contrary to the Trust's policies 
for it to hold a future delivery contract for the sale of securities 
which it does not own.  Established markets are available for future 
delivery contracts, including financial futures exchanges and the over-
the-counter market.

5.  Investments Purchased for Forward Delivery.  Institutional investors 
such as the Trust often enter into commitments to take delivery of 
securities at a future time under specified terms of purchase.  Such 
transactions sometimes appear advantageous because they may provide an 
opportunity to acquire an investment otherwise unavailable, or with more 
attractive terms than are currently available or anticipated for the 
future.  Such transactions, however, can involve a risk that the yields 
available in the market when the delivery takes place may actually be 
higher than those obtained in the transaction itself, and a risk that 
the investor's available cash may be less than projected, possibly 
necessitating a disadvantageous resale of the securities purchased or of 
other portfolio securities at a loss to the Trust.  Securities purchased 
for forward delivery do not accrue interest until they are delivered.  
The Trust intends to enter into forward delivery transactions when it 
deems them advisable, but to reduce its exposure to price instability 
through changes in interest rates before the transactions are completed, 
it has a policy that these commitments will only be undertaken in 
connection with securities having maturities of one year or less.

U.S. Government Securities.  As used in the Prospectus and in this 
Statement of Additional Information, the term "U.S. Government 
securities" refers to a variety of securities which are issued or 
guaranteed by the United States Treasury, by various agencies of the 
United States Government, and by various instrumentalities which have 
been established or sponsored by the United States Government, and to 
certain interests in the foregoing types of U.S. Government securities.  
Except for U.S. Treasury securities, these obligations, even those which 
are guaranteed by federal agencies or instrumentalities, may or may not 
be backed by the "full faith and credit" of the United States.  In the 
case of securities not backed by the full faith and credit of the United 
States, the investor must look principally to the agency issuing or 
guaranteeing the obligation for ultimate repayment, and may not be able 
to assert a claim against the United States itself in the event the 
agency or instrumentality does not meet its commitments.

Treasury securities include Treasury bills, Treasury notes and Treasury 
bonds.  Some of the Government agencies which issue or guarantee 
securities are the Department of Housing and Urban Development, the 
Department of Health and Human Services, the Government National 
Mortgage Association, the Farmers Home Administration, the Department of 
Transportation, the Department of Energy, the Department of the 
Interior, the Department of Commerce, the Department of Defense and the 
Small Business Administration.  Other Government agencies and 
instrumentalities which issue or guarantee securities include the 
Export-Import Bank, the Federal Farm Credit System, the Federal Home 
Loan Banks, the Federal National Mortgage Association, the Federal Home 
Loan Mortgage Corporation and the Student Loan Marketing Association.  
International development organizations which operate under sponsorship 
of the U.S. Government and which issue or guarantee securities (although 
the Trust does not presently intend to hold such securities in its 
portfolio) include the Inter-American Development Bank, the Asian 
Development Bank and the International Bank for Reconstruction and 
Development.

When used herein, the term "U.S. Government securities" includes 
securities issued or guaranteed by any of the foregoing entities or by 
any other agency or instrumentality established or sponsored by the 
United States Government, and participation interests (with unaffiliated 
persons) in and instruments evidencing deposit or safekeeping for any of 
the foregoing.  Participation interests are pro-rata interests in U.S. 
Government securities held by others; instruments evidencing deposit or 
safekeeping are documentary receipts for such original securities held 
in custody by others.

Maturities.  As used in this Statement of Additional Information and in 
the Prospectus, the term "effective maturity" means either the actual 
stated maturity of the investment, the time between its scheduled 
interest rate adjustment dates (for variable rate securities), or the 
time between its purchase settlement and scheduled future resale 
settlement pursuant to a resale or optional resale under fixed terms 
arranged in connection with the purchase, whichever period is shorter.  
A "stated maturity" means the time scheduled for final repayment of the 
entire principal amount of the investment under its terms.  "Short-term" 
means a maturity of one year or less, while "long-term" means a longer 
maturity.

INVESTMENT LIMITATIONS

The Trust has adopted as fundamental policies the following limitations 
on its investment activities, which may not be changed without a 
majority vote of the Trust's shareholders as defined in the Investment 
Company Act of 1940 (see "Organization of the Trust").

1.  Permissible Investments.  Subject to the investment policies from 
time to time adopted by the Trustees, the Trust may purchase U.S. 
Treasury bills, notes, bonds, or other debt obligations issued or 
guaranteed by the U.S. Government or any of its agencies or 
instrumentalities (including international membership development banks 
and negotiable certificates of deposit the principal amount of which is 
insured by the Federal Deposit Insurance Corporation or participation 
interests (with unaffiliated persons) therein, or instruments evidencing 
deposit or safekeeping of U.S. Government securities (see "Supplemental 
Investment Policies"); any of these securities may be subject to 
repurchase agreements with financial institutions or securities dealers 
or may be purchased from any person, under terms and arrangements 
determined by the Trust, for future delivery.  Any of these securities 
may have limited markets and may be purchased with restrictions on 
transfer imposed by the Government agency or instrumentality involved or 
for other reasons, to the extent the Trustees permit; however, the Trust 
may not invest in securities for which there is no readily available 
market, if at the time of acquisition more than 15% of the Trust's net 
assets would be invested in such securities.

2.  Borrowing and Lending.  The Trust may not obtain bank loans, except 
for extraordinary or emergency purposes.  The Trust may enter into 
reverse repurchase agreements in amounts not exceeding 25% of its total 
assets (including the proceeds of the reverse repurchase transactions) 
for purposes of purchasing other securities.  The Trust may not obtain 
loans or enter into reverse repurchase agreements in total amounts 
exceeding one-third of such total assets for any purpose, including the 
meeting of cash withdrawal requests or for extraordinary purposes.  The 
Trust may not mortgage, pledge or hypothecate any assets to secure bank 
loans, except in amounts not exceeding 15% of its net assets taken at 
cost, and only for extraordinary or emergency purposes.  The Trust may 
loan its portfolio securities in an amount not in excess of one-third of 
the value of the Trust's gross assets, provided collateral satisfactory 
to the Trustees is continuously maintained in amounts not less than the 
value of the securities loaned.

3.  Other Activities.  The Trust may not act as an underwriter, make 
short sales (or maintain a short position), or write put or call options 
or combinations thereof.  Nor may the Trust purchase securities on 
margin (except for customary credit used in transaction clearance), 
invest in commodities or in real estate, or acquire shares of other 
investment companies, except that the foregoing prohibition against 
investment in "commodities" by the Trust does not preclude the use of 
financial futures contracts to make purchases or sales of U.S. 
Government securities, provided the transactions would otherwise be 
permitted under the Trust's investment policies.

The Trust may not knowingly take any investment action which has the 
effect of eliminating its tax exemption under Sub-Chapter M of the 
Internal Revenue Code (see "Additional Tax Matters").

Notwithstanding the fundamental policies described above, as a matter of 
operating policy, in order to comply with certain applicable State 
restrictions, the Trust will not pledge, mortgage or hypothecate in 
excess of 10% of its net assets at market value.  The Trust has adopted 
the additional restriction, notwithstanding Paragraph 1 above, that it 
will not invest more than 10% of its net assets at the time of purchase 
in illiquid assets and securities for which there is no readily 
available market (which include fully insured certificates of deposit, 
unless the Trustees determine they are readily marketable) and in 
repurchase agreements and matched purchase/sale transactions that cannot 
be terminated within seven days.  Matched purchase/sales generally 
involve the purchase of liquid securities coupled with a sale for future 
delivery.  Future delivery contracts traded on an organized exchange 
(such as the Chicago Board of Trade or the International Monetary 
Market) are considered liquid, while such contracts executed in the 
over-the-counter market may be illiquid, if a readily available futures 
market has not developed.  Liquidity of a matched purchase/sale 
transaction requires liquidity of both of its parts; the securities 
purchased and the future delivery sale contract.  The sale contract may 
be liquid by the existence of a readily available market for it or by a 
contractual provision permitting delivery at any time within seven days.

THE INVESTMENT ADVISOR
   
Madison Mosaic (previously known as Bankers Finance Advisors, LLC), 1655 
    
Fort Myer Drive, Arlington, Virginia 22209-3108, is the investment 
adviser to the Trust and is called the "Advisor" throughout this 
Statement of Additional Information and the Prospectus.  The Advisor is 
responsible for the investment management of the Trust and is authorized 
to execute the Trust's portfolio transactions, to select the methods and 
firms with which such transactions are executed, to oversee the Trust's 
operations, and otherwise to administer the affairs of the Trust as it 
deems advisable.  In the execution of these responsibilities, the 
Advisor is subject to the investment policies and limitations of the 
Trust described in the Prospectus and this Statement of Additional 
Information, to the terms of the Declaration of Trust and the Trust's 
By-Laws, and to written directions given from time to time by the 
Trustees.

The Advisor is a wholly-owned subsidiary of Madison Investment Advisors, 
Inc.  ("Madison"), 6411 Mineral Point Road, Madison, Wisconsin.  Madison 
is a registered investment advisor and has numerous advisory clients.  
Madison was founded in 1973 and has no business affiliates other than 
those described in the Prospectus and this Statement of Additional 
Information.  Madison operates Madison Scottsdale in Scottsdale, 
Arizona.

The Investment Advisory Agreement is subject to annual review and 
approval by the Trustees, including a majority of those Trustees who are 
not "interested persons," as defined in the Investment Company Act of 
1940.  The investment advisory agreement was approved by shareholders 
for an initial two year term at a special meeting of shareholders held 
in July 1996.

The Investment Advisory Agreement may be terminated at any time, without 
penalty, by the Trustees or by the vote of a majority of the outstanding 
voting securities, or by the Advisor, upon sixty days' written notice to 
the other party.  The Investment Advisory Agreement may not be assigned 
by the Advisor, and will automatically terminate upon any assignment.

Background of the Advisor.  The Advisor was formed in 1996 by Madison 
for the purpose of providing investment management services to the 
Mosaic family of mutual funds, including the Trust.  The Advisor 
purchased the investment management assets of the former advisor to the 
Trust, Bankers Finance Investment Management Corp., on July 31, 1996.  
For periods prior to July 31, 1996, references in this Statement of 
Additional Information and in the Prospectus to the "Advisor" refer to 
Bankers Finance Investment Management Corp.  The Advisor also serves as 
the investment advisor to Mosaic Equity Trust, Mosaic Income Trust and 
Mosaic Tax-Free Trust.  

Management.  Frank E. Burgess is President, Treasurer and Director of 
Madison and Vice President of the Adviser.  Mr. Burgess owns a majority 
of the controlling interest of Madison, which, in turn, controls the 
Adviser.  Mr. Burgess is also a Trustee and Vice President of the Trust.  
Mr. Burgess holds the same positions with Mosaic Equity Trust, Mosaic 
Income Trust and Mosaic Tax-Free Trust.  Katherine L. Frank is President 
and Treasurer of the Advisor and Vice President of Madison.  Ms. Frank 
holds the same positions with Mosaic Equity Trust, Mosaic Income Trust 
and Mosaic Tax-Free Trust.

Advisory Fee and Expense Limitations.  For its services under the 
Investment Advisory Agreement, the Advisor receives a fee, payable 
monthly, calculated as 1/2 percent per annum of the average daily net 
assets of the Trust's portfolio during the month.  Such percentage does 
not decrease as net assets increase.  The Advisor may waive or reduce 
such fee during any period.  The Advisor may also reduce such fee on a 
permanent basis, without any requirement for consent by the Trust or its 
shareholders, under such terms as it may determine, by written notice 
thereof to the Trust.

The Advisor has agreed to reimburse the Trust for all of its expenses, 
excluding securities transaction commissions and expenses, taxes, 
interest and extraordinary and non-recurring expenses, which exceed 
during any fiscal year one and one-half percent of the Trust's daily 
average net assets up to $40 million and one percent of the amount, if 
any, by which such assets exceed $40 million.

In addition, the Advisor has agreed, in any event, to be responsible for 
the fees and expenses of the Trustees and officers of the Trust who are 
affiliated with the Advisor and its various promotional expenses 
(including the distribution of Prospectuses to potential shareholders).  
Other than investment management and the related expenses, and the 
foregoing items, the Advisor is not obligated to provide or pay for any 
other services to the Trust, although it may elect to do so.

The Investment Advisory Agreement permits sharing of the Adviser's fee 
with other persons, subject to the prior approval of such arrangements 
by the Trustees, including a majority of those who are not interested 
persons of the Trust.  Under regulations of the Securities and Exchange 
Commission such arrangements are permissible in connection with the 
distribution of investment company shares, if the payments of the shared 
fee amounts are made out of the investment adviser's own resources.  
Prior to its implementation the Trustees will approve any arrangement to 
share the Advisor's fees and will satisfy themselves that such payments 
are made from the Advisor's own resources.  During the fiscal years 
ending March 31, 1995, 1996 and 1997, and September 30, 1997, the 
Advisor received advisory fees of $506,333, $410,098, $273,026, and 
$129,459, respectively, from the Trust.

ORGANIZATION OF THE TRUST

The Declaration of Trust, dated February 14, 1979, has been filed with 
the Secretary of State of the Commonwealth of Massachusetts and the 
Clerk of the City of Boston, Massachusetts.  The Prospectus contains 
general information concerning the Trust's form of organization and its 
shares (see "The Trust and Its Shares"), including the series of shares 
currently authorized.

Shares and Classes of Shares.  The Trustees may authorize at any time 
the creation of additional series of shares (the proceeds of which would 
be invested in separate, independently managed portfolios) and 
additional classes of shares within any series (which would be used to 
distinguish among the rights of different categories of shareholders, as 
might be required by future regulations or other unforeseen 
circumstances) with such preferences, privileges, limitations, and 
voting and dividend rights as the Trustees may determine.  All 
consideration received by the Trust for shares of any additional series 
or class, and all assets in which such consideration is invested, would 
belong to that series or class (but classes may represent proportionate 
undivided interests in a series), and would be subject to the 
liabilities related thereto.  The Investment Company Act of 1940 would 
require the Trust to submit for the approval of the shareholders of any 
such additional series or class any adoption of an investment advisory 
contract or any changes in the Trust's fundamental investment policies 
related to the series or class.

The Trustees may divide or combine the shares into a greater or lesser 
number of shares without thereby changing the proportionate interests in 
the Trust.  Upon any liquidation of the Trust, the shareholders are 
entitled to share pro-rata in the liquidation proceeds available for 
distribution.

Voting Rights.  The voting rights of shareholders are not cumulative, so 
that holders of more than 50 percent of the shares voting can, if they 
choose, elect all Trustees being selected, while the holders of the 
remaining shares would be unable to elect any Trustees.  As of November 
28, 1997, no person was known to the Trust to own beneficially or of 
record 5% or more of its shares.

Because there is not a requirement for annual elections of Trustees, the 
Trust does not anticipate having regular annual shareholder meetings.  
Shareholder meetings will be called as necessary to consider questions 
requiring a shareholder vote.  The selection of the Trust's independent 
auditors will be submitted to a vote of ratification by the shareholders 
at any annual meetings held by the Trust.  Any change in the Declaration 
of Trust, in the Investment Advisory Agreement (except for reductions of 
the Advisor's fee), in the Services Agreement, or in the fundamental 
investment limitations of the Trust must be approved by a majority of 
the shareholders before it can become effective.  A "majority" is 
constituted by either 50 percent of all shares of the Trust or 67 
percent of the shares voted at an annual meeting or special meeting of 
shareholders at which at least 50 percent of the shares are present or 
represented by proxy.

The Declaration of Trust provides that two-thirds of the holders of 
record of the Trust's shares may remove a Trustee from office by votes 
cast in person or by proxy at a meeting called for the purpose.  A 
Trustee may also be removed from office provided two-thirds of the 
holders of record of the Trust's shares file declarations in writing 
with the Trust's Custodian.

Shareholder Liability.  Under Massachusetts law, the shareholders of an 
entity such as the Trust may, under certain circumstances, be held 
personally liable for its obligations.  The Declaration of Trust 
contains an express disclaimer of shareholder liability for acts or 
obligations of the Trust and requires that notice of such disclaimer be 
given in each agreement, obligation or instrument, entered into or 
executed by the Trust or the Trustees.  The Declaration of Trust 
provides for indemnification out of the Trust property of any 
shareholder held personally liable for the obligations of the Trust.  
The Declaration of Trust also provides that the Trust shall, upon 
request, assume the defense of any claim made against any shareholder 
for any act or obligation of the Trust and satisfy any judgment thereof.  
The risk of a shareholder incurring financial loss on account of status 
as a shareholder is limited to circumstances in which the Trust itself 
would be unable to meet its obligations.

Liability of Trustees and Others.  The Declaration of Trust provides 
that the officers and Trustees of the Trust will not be liable for any 
neglect, wrongdoing, errors of judgment, or mistakes of fact or law, 
except that they shall not be protected from liability arising out of 
willful misfeasance, bad faith, gross negligence, or reckless disregard 
of their duties to the Trust.  Similar protection is provided to the 
Advisor under the terms of the Investment Advisory Agreement and the 
Services Agreement.  In addition, protection from personal liability for 
the obligations of the Trust itself, similar to that provided to 
shareholders, is provided to all Trustees, officers, employees and 
agents of the Trust.

*Trustee deemed to be an "interested person" of the Trust as the term is 
defined in the Investment Company Act of 1940.  Only those persons named 
in the table of Trustees and officers who are not interested persons of 
the Trust are eligible to be compensated by the Trust.  The compensation 
of each non-interested Trustee who may be compensated by the Trust has 
been fixed at $6,000 per year, to be pro-rated according to the number 
of regularly scheduled meetings each year.  Four Trustees' meetings are 
currently scheduled to take place each year.  In addition to such 
compensation, those Trustees who may be compensated by the Trust shall 
be reimbursed for any out-of-pocket expenses incurred by them in 
connection with the affairs of the Trust.  Mr. Kleppe will receive 
annual compensation from the Trust and from the other investment 
companies managed by the Advisor or Madison (see "the Investment 
Advisor") totalling $15,000.  Mr. Imhoff and Mr. Wheeler received annual 
compensation from the Trust and from other investment companies managed 
by the Advisor or Madison totalling $18,000 through June 13, 1997, and 
thereafter will be compensated in the same amount as Mr. Kleppe.

During the last fiscal year of the Trust, the Trustees were compensated as 
follows:

                      Aggregate        Total Compensation from
                      Compensation     Trust and Fund Complex
                      from Trust       Paid to Trustees (a)

Frank E. Burgess             0                    0
Thomas S. Kleppe        $6,000              $15,000
James R. Imhoff, Jr.    $6,000              $18,000
Lorence D. Wheeler      $6,000              $18,000

(a) Prior to June 13, 1997, the complex was comprised of 4 trusts and 
three corporations with a total of 16 funds and/or series.  As of June 
13, 1997, the complex is comprised of 4 trusts and one corporation with 
a total of 15 funds and/or series.

***Member of the Audit Committee of the Trust.  The Audit Committee is 
responsible for reviewing the results of each audit of the Trust by its 
independent auditors and for recommending the selection of independent 
auditors for the coming year.

Under the Declaration of Trust, the Trustees are entitled to be 
indemnified by the Trust to the fullest extent permitted by law against 
all liabilities and expenses reasonably incurred by them in connection 
with any claim, suit or judgment or other liability or obligation of any 
kind in which they become involved by virtue of their service as 
Trustees of the Trust, except liabilities incurred by reason of their 
willful misfeasance, bad faith, gross negligence or reckless disregard 
of the duties involved in the conduct of their office.  As of November 
28, 1997, the Trustees and officers of the Trust directly or indirectly 
owned as a group less than five percent of the outstanding shares of the 
Trust.

ADMINISTRATIVE AND OTHER EXPENSES

Except for certain expenses assumed by the Advisor (see "The Investment 
Advisor"), the Trust is responsible for payment from its assets of all 
   
of its expenses which are satisifed pursuant to the Services Agreement 
described below.  These expenses can include any of the business or 
    
other expenses of organizing, maintaining and operating the Trust.  
Certain expense items which may represent significant costs to the Trust 
include the payment of the Advisor's fee; the expense of shareholder 
accounting, customer services, and calculation of net asset value; the 
fees of the Custodian, of the Trust's independent accountants, and of 
legal counsel to the Trust; the expense of registering the Trust and its 
shares, of printing and distributing prospectuses and periodic financial 
reports to current shareholders, and of trade association membership; 
the expense of preparing shareholder reports, proxy materials and of 
holding shareholder meetings of the Trust.  The Trust is also 
responsible for any extraordinary or non-recurring expenses it may 
incur.

Services Agreement.  The Trust does not have any officers or employees 
who are paid directly by the Trust.  The Trust has entered into a 
Services Agreement with the Adviser for the provision of operational and 
other services required by the Trust.  Such services may include the 
functions of shareholder servicing agent and transfer agent, bookkeeping 
and portfolio accounting services, the handling of telephone inquiries, 
cash withdrawals and other customer service functions including 
monitoring wire transfers, and providing to the Trust appropriate 
supplies, equipment and ancillary services necessary to the conduct of 
its affairs.  The Trust is registered with the Securities and Exchange 
Commission as the transfer agent for its shares and acts as its own 
dividend-paying agent; while transfer agent personnel and facilities are 
included among those provided to the Trust under the Services Agreement, 
the Trust itself is solely responsible for its transfer agent and 
dividend payment functions and for the supervision of those functions by 
its officers.

All such services provided to the Trust by the Advisor are rendered at a 
flat percentage fee calculated as a percentage of average daily net 
assets, reviewed and approved at least annually by the Trustees.  Such 
fee is expected to approximate or be below the cost of providing such 
services.  The term "cost" includes both direct expenditures and the 
related overhead costs, such as depreciation, employee supervision, rent 
and the like; reimbursements to the Advisor pursuant to the Services 
Agreement are in addition to and independent of payments made pursuant 
to the Investment Advisory Agreement.  The Advisor provides such 
services to Mosaic Equity Trust, Mosaic Income Trust, and Mosaic Tax-
Free Trust.  
       
Distribution Agreement.  GIT Investment Services, Inc.  acts as the 
Trust's Distributor pursuant to a Distribution Agreement, dated February 
11, 1983, without compensation under such Agreement.  This Agreement has 
an initial term of two years and may thereafter continue in effect only 
if approved annually by the Trustees, including a majority of those who 
are not "interested persons," as defined in the Investment Company Act 
of 1940.  The Agreement provides for distribution of the Trust's shares 
without a sales charge to the investor.  The Distributor may act as the 
Trust's agent for any sales of its shares, but the Trust may also sell 
its shares directly to any person.  The Distributor makes the Trust's 
shares continuously available to the general public in those States 
where it has qualified to do so, but has assumed no obligation to 
purchase any of the Trust's shares.  The Distributor is wholly owned by 
A. Bruce Cleveland, its President.

PORTFOLIO TRANSACTIONS

Decisions as to the purchase and sale of securities, and decisions as to 
the execution of these transactions, including selection of market, 
broker or dealer and the negotiation of commissions are to be made by 
the Advisor, subject to review by the officers and Trustees.

In general, in the purchase and sale of portfolio securities the Trust 
seeks to obtain prompt and reliable execution of orders at the most 
favorable prices or yields.  In determining the best price and 
execution, the Advisor may take into account a dealer's operational and 
financial capabilities, the type of transaction involved, the dealer's 
general relationship with the Advisor, and any statistical, research or 
other services provided by the dealer to the Advisor.  To the extent 
such non-price factors are taken into account the execution price paid 
may be increased, but only in reasonable relation to the benefit of such 
non-price factors to the Trust as determined in good faith by the 
Advisor.  Brokers or dealers who execute portfolio transactions for the 
Trust may also sell its shares; however, any such sales will not be 
either a qualifying or disqualifying factor in the selection of brokers 
or dealers.  During its three most recent fiscal years, the Trust did 
not pay any brokerage commissions.

The Trust expects that most portfolio transactions will be made directly 
with a dealer acting as a principal thus, not involving the payment of 
commissions; however, any purchases from an underwriter or selling group 
could involve payments of fees and concessions to the underwriting or 
selling group.  The Trust also reserves the right to purchase portfolio 
securities through an affiliated broker, when deemed in the Trust's best 
interests by the Advisor, provided that: (1) the transaction is in the 
ordinary course of the broker's business; (2) the transaction does not 
involve a purchase from another broker or dealer; (3) compensation to 
the broker in connection with the transaction is not in excess of one 
percent of the cost of the securities purchased; and (4) the terms to 
the Trust for purchasing the securities, including the cost of any 
commissions, are not less favorable to the Trust than terms concurrently 
available from other sources.  Any compensation paid in connection with 
such a purchase will be in addition to fees payable to the Advisor under 
the Investment Advisory Agreement.  The Trust does not anticipate that 
any such purchases through affiliates will represent a significant 
portion of its total activity; no such transactions took place during 
the Trust's three most recent fiscal years.

Although the Trust intends normally to hold its investments to maturity, 
the short maturities of these investments are expected to result in a 
relatively high rate of portfolio turnover.  The actual turnover rate 
will not be a limiting factor in the Trust's decisions as to purchases 
and sales of portfolio securities.  

SHAREHOLDER TRANSACTIONS

The Prospectus describes the basic procedures for investing in the Trust 
(see "How to Purchase Shares" and "How to Redeem Shares").  The 
following information concerning other investment procedures is 
presented to supplement the information contained in the Prospectus.

Shareholder Service Policies.  The Trust's policies concerning 
shareholder services are subject to change from time to time.
   
Minimum Initial Investment and Minimum Balance.  The Trust reserves the 
right to change the minimum account size below which an account is 
subject to a monthly service charge or to involuntary closing by the 
Trust.  The Trust may change its minimum amount for subsequent 
investments by 30 days written notice to its shareholders.
    
Special Service Charges.  The Trust further reserves the right, after 30 
days written notice to shareholders, to impose special service charges 
for services that are not regularly afforded to shareholders, such 
service charges may include but are not limited to fees for stop payment 
orders and returned checks.  The Trust's standard service charges are 
also subject to adjustment from time to time.

Share certificates will not be issued.

Subaccounting Services.  The Trust offers subaccounting services to 
institutions.  The Trustees reserve the right to determine from time to 
time such guidelines as they deem appropriate to govern the level of 
subaccounting service that can be provided to individual institutions in 
differing circumstances.  Normally, the Trust's minimum initial 
investment to open an account will not apply to subaccounts; however, 
the Trust reserves the right to impose the same minimum initial 
investment requirement that would apply to regular accounts, if it deems 
that the cost of carrying a particular subaccount or group of 
subaccounts is otherwise likely to be excessive.  The Trust may provide 
and charge for subaccounting services which it determines exceed those 
services which can be provided without charge; the availability and cost 
of such additional services will be determined in each case by 
negotiation between the Trust and the parties requesting the additional 
services.  The Trust is not presently aware of any such services for 
which a charge will be imposed.

Crediting of Investments.  The Trust reserves the right to reject any 
investment in the Trust for any reason and may at any time suspend all 
new investment in the Trust.  The Trust may also, in its discretion or 
at the instance of the Advisor, decline to give recognition as an 
investment to funds wired for credit to either type of account, until 
such funds are actually received by the Trust.  Under present federal 
regulatory guidelines, the Advisor may be responsible for any losses 
resulting from changes in the Trust's net asset value which are incurred 
by the Trust as a result of failure to receive funds from a shareholder 
to whom recognition for investment was given in advance of receipt of 
payment.

If shares are purchased to be paid for by wire and the wire is not 
received by the Trust or if shares are purchased by a check which, after 
deposit, is returned unpaid or proves uncollectible, then the share 
purchase may be canceled immediately or the purchased shares may be 
immediately redeemed.  The shareholder that gave notice of the intended 
wire or submitted the check will be held fully responsible for any 
losses so incurred by the Trust, the Advisor or the Distributor.  

Checks.  Checks drawn on foreign banks will not be considered received 
in federal funds until the Trust has actual receipt of payment in 
immediately available U.S. dollars after submission of the check for 
collection; collection of such checks through the international banking 
system may require 30 days or more.

Wire.  Funds received by wire are normally converted into shares in the 
Trust at the net asset value next determined.

Purchase Orders from Brokers.  An order to purchase shares which is 
received by the Trust from a securities broker will be considered 
received in proper form for the net asset value per share determined as 
of the close of business of the New York Stock Exchange on the day of 
the order, provided the broker received the order from its customer 
prior to that time and transmitted it to the Trust prior to 4 p.m.  EST.  
Shareholders who invest in the Trust through a broker may be charged a 
commission for handling the transaction.  A shareholder may deal 
directly with the Trust anytime to avoid the fee.

REDEMPTIONS

The value of shares redeemed will be determined according to the share 
net asset value next calculated after the request has been received in 
proper form (See "Determination of Net Asset Value.").  Thus, any such 
request received in proper form prior to 4 p.m.  Washington, DC time on 
a business day will reflect the net asset value calculated at that time; 
later withdrawal requests will be processed to reflect the share net 
asset value figure calculated on the next day the calculation is made.  
The Trust calculates net asset values each day the New York Stock 
Exchange is open for trading.

Net asset value determinations will apply as of the day the redemption 
order is submitted in proper form.  A redemption request may not be 
deemed to be in proper form unless a signed account application has been 
properly submitted to the Trust by the shareholder or such an 
application is submitted with the withdrawal request.

A shareholder draft check drawn against an account will not be 
considered in proper form unless sufficient collected funds are 
available in the account on the day the check is presented for payment.

The "day of withdrawal" for share redemptions refers to the day on which 
corresponding funds are paid out by the Trust, whether by wire transfer, 
exchange between accounts, check, or debit of the investor's account to 
cover a customer checks presented for payment.  

Shareholders should be aware that it is possible, should the share net 
asset value of the Trust fall, that amounts available for withdrawal 
from an account could be less than the amount of the original 
investment.  All redemptions from the Trust will be affected by the 
redemption of the appropriate number of whole and fractional shares 
having a net asset value equal to the amount withdrawn.

The Trust will use its best efforts in normal circumstances to handle 
withdrawals within the times previously given.  However, it may for any 
reason it deems sufficient suspend the right of redemption or postpone 
payment for any shares in the Trust for any period up to seven days.  
The Trust's sole responsibility with regard to withdrawals shall be to 
process, within the aforementioned time period, redemption requests in 
proper form.  Neither the Trust, its affiliates, nor the Custodian can 
accept responsibility for any act or event which has the effect of 
delaying or preventing timely transfers of payment to or from 
shareholders.  By law, payment for shares in the Trust may be suspended 
or delayed for more than seven days only during any period when the New 
York Stock Exchange is closed, other than customary weekend and holiday 
closings; when trading on such Exchange is restricted, as determined by 
the Securities and Exchange Commission; or during any period when the 
Securities and Exchange Commission has by order permitted such 
suspension.
       
When an account is closed, the Trust reserves the right to make payment 
by check of any final dividends declared to the date of the redemption 
to close the account, but not yet paid, on the same day such dividends 
are paid to other shareholders, rather than at the time the account is 
closed.

Inter-Fund Exchange.  Funds exchanged between shareholder accounts will 
earn its final days dividend on the day of exchange.
       
The Trust reserves the right, when it deems such action necessary to 
protect the interests of its shareholders, to refuse to honor withdrawal 
requests made by anyone purporting to act with the authority of another 
person or on behalf of a corporation or other legal entity.  Each such 
individual must provide a corporate resolution or other appropriate 
evidence of his or her authority or identity satisfactory to the Trust.  
The Trust reserves the right to refuse any third party redemption 
requests.

If, in the opinion of the Trustees, extraordinary conditions exist which 
make cash payments undesirable, payments for any shares redeemed may be 
made in whole or in part in securities and other property of the Trust; 
except, however, that the Trust has elected, pursuant to rules of the 
Securities and Exchange Commission, to permit any shareholder of record 
to make redemptions wholly in cash to the extent the shareholder's 
redemptions in any 90-day period do not exceed the lesser of 1% of the 
aggregate net assets of the Trust or $250,000.  Any property of the 
Trust distributed to shareholders will be valued at fair value.  In 
disposing of any such property received from the Trust, a shareholder 
might incur commission costs or other transaction costs.  There is no 
assurance that a shareholder attempting to dispose of any such property 
would actually receive the full net asset value for it.  Except as 
described herein, however, the Trust intends to pay for all share 
redemptions in cash.
   
It is the shareholder's obligation to inform the Trust of address 
changes.  The Trust will exercise reasonable care to ascertain the 
correct address of lost shareholders.  The Trust will conduct two 
database searches and use at least one information database service.  
The search will be conducted at no cost to the shareholder.  The Trust 
will not, however, perform such searches if the shareholder's account is 
less than $25, if the shareholder is not a natural person or the Trust 
has received documentation that the shareholder is deceased.  If a lost 
shareholder cannot be located after such procedures, such shareholder's 
account may be escheated to the state of the shareholder's last 
residence.  No interest will accrue on amounts represented by uncashed 
distribution or redemption checks.
    
RETIREMENT PLANS

General information on retirement plans offered by the Trust is provided 
in the Prospectus (see "Retirement Plans").  Additional information 
concerning these retirement plans is provided below.

IRAs.  The minimum initial contribution for a Traditional IRA or Roth 
IRA plan with the Trust is $500.  Spousal IRAs are accepted by creating 
two accounts, one for each spouse.  For IRAs opened in connection with a 
payroll deduction or SEP plan, the Trust may waive the initial 
investment minimum on a case-by-case basis.
   
Education IRAs.  The Trust offers Education IRA accounts as of January 
1, 1998.  The Education IRA should be established in conjunction with an 
Education IRA Plus account with a minimum $100 monthly investment in 
order to avoid an annual $12 custodian fee.
    
The Trust's annual account maintenance fee is deducted from the account 
at the end of each year or at the time of the account's closing unless 
prepaid by the shareholder.

Other Retirement Plans or Retirement Plan Accounts.  The Trust offers 
prototype Keogh, SIMPLE, 401(k) and 403(b) retirement plans.  The Trust 
may waive the initial investment minimum for Education IRA, prototype or 
other retirement plan accounts on a case by case basis.

DECLARATION OF DIVIDENDS

Substantially all of the Trust's accumulated net income is declared as 
dividends, when calculated, each business day.  Calculation of 
accumulated net income for each of the Trust's portfolios will be made 
just prior to calculation of the portfolio's net asset value (see 
"Determination of Net Asset Value").  The amount of such net income will 
reflect the interest income (plus any discount earned less premium 
amortized), and expenses accrued by the Fund reflected since the 
previously declared dividends.

In order to facilitate its objective of stabilizing the price of its 
shares at $1.00, the Trust intends normally to reflect any portfolio 
realized gains and losses and unrealized appreciation and depreciation, 
to the extent the Trust deems the amount material, in daily dividends, 
rather than in share prices.

Dividends are payable to shareholders of record at the time as of which 
they are determined.  Dividends are paid in the form of additional 
shares of the Trust credited to the respective investor account at the 
end of each calendar month (or normally when the account is closed, if 
sooner), unless the shareholder makes a written election to receive 
dividends in cash.

Notice of payment of dividends will be mailed to each shareholder 
quarterly.  For tax purposes each shareholder will also receive an 
annual summary of dividends paid by the Trust and the extent to which 
they constitute capital gains dividends (see "Additional Tax Matters").  
Any investor purchasing shares in an account of the Trust as of a 
particular net asset value determination (the close of the New York 
Stock Exchange) on a given day will not be considered a shareholder of 
record for the dividend declaration made that day; but an investor 
withdrawing as of such determination will be considered a shareholder of 
record with respect to the shares withdrawn.  A "business day" will be 
any day the New York Stock Exchange is open for trading.

Net realized capital gains, if any, will be distributed to shareholders 
at least annually as capital gains dividends.

DETERMINATION OF NET ASSET VALUE
   
The net asset value of each portfolio of the Trust, and of the 
respective shares, is calculated each day the New York Stock Exchange is 
open for trading.  Net asset value is not calculated on New Year's Day, 
the observance of Martin Luther King, Jr.'s Birthday, President's Day, 
Good Friday, the observance of Memorial Day, Independence Day, Labor 
Day, Thanksgiving Day, Christmas Day and on other days the New York 
Stock Exchange is closed for trading.  The net asset value calculation 
is made as of a specific time of day, as described in the Prospectus.
    
Net asset value per share of each portfolio is determined by adding the 
value of all its securities and other assets, subtracting its 
liabilities and dividing the result by the total number of outstanding 
shares that represent an interest in the portfolio.  These calculations 
are performed by the Trust, pursuant to the Services Agreement (see 
"Administrative and Other Expenses").  The Trust's shares are redeemed 
at net asset value.  Shares of the Trust are offered at net asset value.

The Trust's securities are valued at their amortized cost, pursuant to 
regulations of the Securities and Exchange Commission ("SEC") intended 
to permit the price of the Trust's shares to be stabilized at $1.00.  
These regulations require the Trust to limit its investments to 
securities that the Trustees determine represent minimal credit risks, 
to limit its maturities to those appropriate to its objective of 
maintaining a stable share price, and in any event to the maturity 
restrictions provided in the Trust's investment policies described in 
the Prospectus.

These regulations also require the Trust to periodically compute the 
market values of its portfolio securities.  If for any reason, including 
a change in market interest rates, the market value computation differs 
by more than 1/2 of 1 percent from the $1.00 per share price, the 
Trustees are required to meet and consider steps to restore the market 
price to $1.00 per share.  Such steps could include adjusting dividends, 
selling portfolio securities before maturity to realize capital gains or 
losses, shortening the portfolio's maturity, or redeeming shares in 
kind.  Such steps could result in dilution of shareholders' interests.

In determining market values for this purpose, the Trustees may 
authorize reliance upon an independent pricing service or other 
valuation technique, which may price securities with reference to market 
transactions in comparable securities and to historical relationships 
among the prices of comparable securities; such prices may also reflect 
an allowance for the impact upon prices of the larger transactions 
typical of trading by institutions.

Should the SEC change its rules governing the "amortized cost" valuation 
method, the Trust reserves the right to use the "penny rounding" method 
of valuation pursuant to the terms of the Trust's exemptive order issued 
by the SEC.

ADDITIONAL TAX MATTERS

Federal Income Tax.  To qualify as a "regulated investment company" and 
avoid Trust-level federal income tax under the Internal Revenue Code 
(the "Code"), the Trust must, among other things, distribute 100% of its 
net income and net capital gains in the fiscal year in which it is 
earned.  The Code also requires the distribution of at least 98% of 
undistributed net income for the calendar year and capital gains 
determined as of October 31 each year before the calendar year-end in 
order to avoid a 4% excise tax.  The Trust intends to distribute all 
taxable income to the extent it is realized to avoid imposition of 
federal excise taxes.

To qualify as a regulated investment company under the Code, the Trust 
must also derive at least 90% of its gross income from dividends, 
interest, gains from the sale or disposition of securities, and certain 
other types of income.  Should it fail to qualify as a "regulated 
investment company" under the Code, the Trust would be taxed as a 
corporation with no allowable deduction for the distribution of 
dividends.

Shareholders of the Trust, however, will be subject to federal income 
tax on any ordinary net income and net capital gains realized by the 
Trust and distributed to shareholders as regular or capital gains 
dividends, whether distributed in cash or in the form of additional 
shares.  Generally, dividends declared by the Trust during October, 
November or December of any calendar year and paid to shareholders 
before February 1 of the following year will be treated for tax purposes 
as received in the year the dividend was declared.  No portion of the 
dividends paid by the Trust to its shareholders is expected to be 
subject to the dividends received deduction for corporations (70% of 
dividends received).

Shareholders who fail to comply with the interest and dividends "back-
up" withholding provisions of the Code (by filing Form W-9 or its 
equivalent, when required) or who have been determined by the Internal 
Revenue Service to have failed to properly report dividend or interest 
income may be subject to a 31% withholding requirement on transactions 
with the Trust.

For tax purposes, the Trust will send shareholders an annual notice of 
dividends paid during the prior year.  Investors are advised to retain 
all statements received from the Trust to maintain accurate records of 
their investment.  Shareholders of the Trust will be subject to federal 
income tax on the net capital gains, if any, realized by each portfolio 
and distributed to shareholders as capital gains dividends.

The Trust reserves the right to involuntarily redeem any of its shares 
if, in its judgment, ownership of the Trust's shares has or may become 
concentrated as to make the Trust a personal holding company under the 
Code.

YIELD CALCULATIONS

For advertising and certain other purposes, the Trust's yield is 
calculated according to a standard formula prescribed by the Securities 
and Exchange Commission.  The yield is calculated by dividing the net 
income (including the benefit of any expenses waived or reimbursed by 
the Advisor) earned on one share during a given seven-day period, 
exclusive of any capital changes, by the initial value of that share 
(normally $1.00), and expressing the result (called the "base period 
return") as an annualized percentage.  The base period return is 
annualized by multiplying it by 365 and dividing the product by seven.

The Trust's "effective yield" is calculated in a similar manner, except 
that the net income earned during a seven-day period is assumed to be 
reinvested at the same rate over a full year, thereby generating 
additional earnings from compounding.  The effective yield is computed 
by adding one to the base period return, raising the result to the power 
equal to 365 divided by seven, and subtracting one from the result, 
which is then expressed as a percentage.

The Trust's standardized yield for the seven-day period ending December 
15, 1997 was 4.73% and its annual effective yield for the same period 
was 4.84%.

Performance Comparisons.  From time to time, in advertisements or in 
reports to shareholders and others, the Trust may compare the 
performance of its portfolio to that of recognized market indices or may 
cite the ranking or performance of its portfolio as reported in 
recognized national periodicals, financial newsletters, reference 
publications, radio and television news broadcasts, or by independent 
performance measurement firms.

The Trust may also compare the performance of its portfolios to that of 
other funds managed by the same Advisor.  It may compare its performance 
to that of other types of investments, substantiated by representative 
indices and statistics for those investments.

Market indices which may be used include those compiled by major 
securities firms, such as Solomon Brothers, Shearson Lehman Hutton, the 
First Boston Corporation, and Merrill Lynch; other indices compiled by 
securities rating or valuation services, such as Ryan Financial 
Corporation and Standard and Poor's Corporation, may also be used.  
Periodicals which report market averages and indices, performance 
information, and/or rankings may include: The Wall Street Journal, 
Investors Daily, The New York Times, The Washington Post, Barron's, 
Financial World Magazine, Forbes Magazine, Money Magazine, Kiplinger's 
Personal Finance, and the Bank Rate Monitor.  Independent performance 
measurement firms include Lipper Analytical Services, Inc., Frank Russel 
Company, SCI and CDA Investment Technologies.

In addition, a variety of newsletters and reference publications provide 
information on the performance of mutual funds, such as the Donoghue's 
Money Fund Report, No-Load Fund Investor, Wiesenberger Investment 
Companies Service, the Mutual Fund Source Book, the Mutual Fund 
Directory, the Switch Fund Advisory, Mutual Fund Investing, the Mutual 
Fund Observer, Morningstar, and the Bond Fund Survey.  Financial news is 
broadcast by the Financial News Network, Cable News Network, Public 
Broadcasting System, and the three major television networks, NBC, CBS 
and ABC, as well as by numerous independent radio and television 
stations.

When the Trust uses Lipper Analytical Services, Inc.  in making 
performance comparisons in advertisements or in reports to shareholders 
or others, the performance of the Trust will be compared to mutual funds 
categorized as "U.S. Government Money Market Funds".  If this category 
should be changed by Lipper Analytical Services, Inc., comparisons will 
be made thereafter based on the revised category.

Average Maturities.  The Trust also calculates average maturity 
information for its portfolio.  The "average maturity" of the portfolio 
on any day is determined by multiplying the number of days then 
remaining to the effective maturity (see "Supplemental Investment 
Policies") of each investment in the portfolio by the value of that 
investment, summing the results of these calculations, and dividing the 
total by the aggregate value of the portfolio that day (determined as of 
1:00 p.m.).  Thus, the average maturity represents a dollar-weighted 
average of the effective maturities of the portfolio investments.  The 
"mean average maturity" of the portfolio over some period, such as seven 
days, a month or a year, represents the arithmetic mean (i.e., simple 
average) of the daily average maturity figures for the portfolio during 
the respective period.

It should be noted that the Trust's yield is not fixed.  In fact the 
yield tends to fluctuate daily and so annualized rates of return should 
not be considered representations of what an investment may earn in any 
future period.  Actual dividends will tend to reflect changes in money 
market interest rates, and will also depend upon the level of the 
Trust's expenses, any realized or unrealized investment gains and 
losses, and the relative results of the Trust's investment policies.  
Thus, at any point in time future yields may be either higher or lower 
than past yields and there is no assurance that any historical yield 
level will continue.

CUSTODIANS AND SPECIAL CUSTODIANS

Star Bank, N.A., 425 Walnut Steet, Cincinnati, OH 45202, is Custodian 
for the cash and securities of the Trust.  The Custodian maintains 
custody of the Trust's cash and securities, handles its securities 
settlements and performs transaction processing for cash receipts and 
disbursements in connection with the purchase and sale of the Trust's 
shares.

From time to time, the Trust may appoint as Special Custodians, certain 
banks, trust companies, and firms which are members of the New York 
Stock Exchange and trade for their own account in the types of 
securities purchased by the Trust.  Such Special Custodians will be used 
by the Trust only for the purpose of providing custody and safekeeping 
services of relatively short duration for designated types of securities 
which, in the opinion of the Trustees or of the Advisor, would most 
suitably be held by such Special Custodians rather than by the 
Custodian.  In the event any such Special Custodian is used, it shall 
serve the Trust only in accordance with a written agreement with the 
Trust meeting the requirements of the Securities and Exchange Commission 
for custodians and approved and reviewed at least annually by the 
Trustees, and, if a securities dealer, only if it delivers to the 
Custodian its receipt for the safekeeping of each lot of securities 
involved prior to payment by the Trust for such securities.

The Trust may also maintain deposit accounts for the handling of cash 
balances of relatively short duration with various banks, as the 
Trustees or officers of the Trust deem appropriate, to the extent 
permitted by the Investment Company Act of 1940.

LEGAL MATTERS AND INDEPENDENT AUDITORS

DeWitt Ross and Stevens, S.C., 8000 Excelsior Drive, Madison, Wisconsin

counsel to the Trust's independent Trustees.

Deloitte & Touche LLP, 117 Campus Drive, Princeton, NJ  08540, serves as 
independent auditors to the Trust.

From time to time the Trust may be or become involved in litigation in 
the ordinary conduct of its business.  Material items of litigation 
having consequences of possible or unspecified damages, if any, are 
disclosed in the notes to the Trust's financial statements (see 
"Financial Statements and Report of Independent Auditors").
