ABBREVIATIONS AND
OTHER INFORMATION

With respect to the Schedules of Investments, the percentage shown for each
investment category reflects the value of investments in that category as a
percentage of total net assets.

Interest rates represent either the stated coupon rate, annualized yield on date
of purchase for discounted notes, or, for floating rate securities, the current
reset rate.

Prerefunding is a procedure in which a bond issuer floats a second bond in order
to pay off the first bond at the first call date. The proceeds from the sale of
the second bond are safely invested, usually in Treasury securities, that will
mature at the first call date of the first bond issue. Those first bonds are
said to be prerefunded after this operation has taken place.

Maturity dates represent the stated date on the security, the next interest
reset date or next puttable dates for floating rate securities or the
prerefunded date for these types of securities.

- --------------------
NOTES TO THE
FINANCIAL STATEMENTS
SEPTEMBER 30, 1998 (UNAUDITED)

1.ORGANIZATION

Northern Funds was organized October 12, 1993 as a Massachusetts business trust
and is registered under the Investment Company Act of 1940 as an open-end
management investment company consisting of 21 portfolios.  The Money Market,
U.S. Government Money Market, U.S. Government Select Money Market, Municipal
Money Market and California Municipal Money Market Funds (collectively the
"Funds") are separate, diversified investment portfolios of Northern Funds,
except the California Municipal Money Market Fund which is a non-diversified
portfolio of Northern Funds.  Non-diversified portfolios may invest a relatively
high percentage of their net assets in obligations of a limited number of
issuers.  Each of the Funds maintains its own investment objective.
  The Funds have entered into an Investment Advisory Agreement with The
Northern Trust Company ("Northern Trust" or the "Adviser").  Northern Trust also
serves as custodian, fund accountant and transfer agent for the Funds.

2.SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies consistently
followed by the Funds.  These policies are in conformity with generally accepted
accounting principles ("GAAP").  The preparation of financial statements in
conformity with GAAP requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.


A VALUATION OF SECURITIES - Short-term investments held by the Funds are valued
  using the amortized cost method, which approximates market value.  Under this
  method, investments purchased at a discount or premium are valued by
  amortizing the difference between the original purchase price and maturity
  value of the issue over the period to maturity.  Guaranteed investment
  contracts are valued at cost plus accrued interest, which approximates market
  value.  Any securities for which no current quotations are readily available
  are valued at fair value as determined in good faith by the Adviser under the
  supervision of the Board of Trustees.

B REPURCHASE AGREEMENTS - During the term of a repurchase agreement, the market
  value of the underlying collateral, including accrued interest, is required
  to equal or exceed the market value of the repurchase agreement.  The
  underlying collateral for all repurchase agreements is held in a customer-
  only account of Northern Trust, as custodian for the Funds, at the Federal
  Reserve Bank of Chicago.
  
C ORGANIZATION COSTS - Organization expenses of approximately $342,000 have
  been deferred and are being amortized on a straight-line basis through 1999.

D INVESTMENT TRANSACTIONS AND INCOME - Investment transactions are recorded as
  of the trade date.  The Funds determine the gain or loss realized from
  investment transactions by using an identified cost basis method.  Interest
  income is recognized on an accrual basis and includes amortization of
  discounts and premiums.

E EXPENSES - The Funds are charged for those expenses that are directly
  attributable to each Fund.  Expenses that are not directly attributable to a
  Fund are typically allocated among the Funds in proportion to their
  respective net assets.

F DISTRIBUTIONS TO SHAREHOLDERS - Dividends from net investment income are
  declared daily and paid monthly.
     Distributions of net realized capital gains, if any, are declared at least
  annually.  Distributions to shareholders are recorded on the ex-dividend
  date.
     The timing and character of distributions determined in accordance with
  federal income tax regulations may differ from financial statement amounts
  determined in accordance with generally accepted accounting principles due to
  differences in the treatment and recognition of investment income and
  realized gains (losses).  These differences are primarily related to capital
  loss carryforwards.  Certain differences in treatment of income and capital
  gains for distributions, which are permanent, may result in periodic
  reclassifications in the Funds' capital accounts.

<PAGE>

G FEDERAL INCOME TAXES - No provision for federal income taxes has been made
  since the Funds intend to comply with the requirements of the Internal
  Revenue Code available to regulated investment companies.
     At March 31, 1998, the California Municipal Money Market Fund had a capital
  loss carryforward, for federal income tax purposes, of approximately $1,000
  due to expire March 31, 2006.  This capital loss carryforward is available to
  offset future gains.

3.INVESTMENT ADVISORY AND OTHER AGREEMENTS

Pursuant to its advisory agreement with the Funds, the Adviser is entitled to
receive a fee, calculated daily and payable monthly, at the annual rates
presented below as applied to each Fund's daily net assets.  For the six months
ended September 30, 1998, the Adviser voluntarily agreed to waive a portion of
its advisory fees as applied to each Fund's daily net assets as shown on the
accompanying Statements of Operations.  Northern Trust had also agreed to
reimburse the Funds as shown on the accompanying Statements of Operations to

   The Funds have entered into an administrative agreement with Sunstone
Financial Group, Inc. ("Sunstone") for certain administrative services.
Pursuant to its administrative agreement with the Funds, Sunstone is entitled to
receive a fee, computed daily and payable monthly, at the annual rate of 0.15%
of each Fund's daily net assets.  For the six months ended September 30, 1998,
Sunstone voluntarily agreed to waive a portion of its administration fees as
shown on the accompanying Statements of Operations.  The waivers and
reimbursements of Northern Trust and Sunstone described above are voluntary and
may be terminated by them at any time at their discretion.

4.  BANK LOANS

The Funds maintain a $5,000,000 revolving bank credit line for liquidity and
other purposes.  Borrowings under this arrangement bear interest at 1% above the
Fed Funds rate and are secured by pledged securities equal to or exceeding 120%
of the outstanding balance.
  As of September 30, 1998, there were no outstanding borrowings.
