Important Information

Through  our  ongoing  efforts to reduce  expenses  and  respond to  shareholder
requests, your annual and semiannual report mailings are "streamlined." One copy
of each report is sent to each address, rather than to every  registered  owner.
For many  shareholders  and their families, this  eliminates  duplicate  copies,
saving paper and postage costs to the Fund.

If you are the  primary  shareholder  on at least  one  account,  prefer  not to
participate in streamlining, and would like to continue receiving one report per
registered account owner, you may request this in writing to:

                  USAA Investment Management Company
                  Attn: Report Mail
                  9800 Fredericksburg Road
                  San Antonio, TX 78284-8916

or phone a Mutual Fund Representative at 1-800-531-8448 during business hours.

This  report is for the  information  of the  shareholders  and  others who have

Message from the President

"We are now ready to move to another  plateau."

Back in 1980 we began to craft a family of mutual  funds  that  would  allow  an
investor to create a diversified  portfolio  suited to an individual's  appetite
for risk.  In  1984  we  started  a  brokerage  service  because we thought some
members might want that.  The two have grown beyond our dreams.  Our fund family
now offers 35  investment  choices  and our  Brokerage Service has become a very
significant  presence  in  its  industry.  We  are  now ready to move to another
plateau.

As I write  this  message,  the USAA  Investment  Management  Company  is in the
process  of  ending  our  long  and  mutually  rewarding  relationship  with BHC
Securities, and taking on all of the responsibilities  of  running our Brokerage
Service.  The term for this is "self-clearing."  It includes our own seat on the
Chicago Stock Exchange.  Shortly after we achieve self-clearing,  we  shall also
move our mutual fund accounts off of an internal  system and onto the facilities
of DST Systems, a Kansas City company  that  processes  very  much of the mutual
fund industry's  transactions.  These two moves will greatly improve our ability
to offer you better service.

Our goal is to give you a single  investment  account which can hold,  track and
report to you on almost any type of  investment  you wish to make. It will offer
features such as low-cost loans based upon your investments,(1) easy movement of
funds,(2) and a single  statement.  It  will also be tied to other USAA services
such as banking, fixed and variable annuities and property and casualty and life
insurance.  We will make this the only investment  account you will need. You'll
be hearing more on this in coming months.

Sincerely,

Michael J.C. Roth, CFA
President and
Vice Chairman of the Board

Message from the Manager

[Photograph of the Portfolio Manager, John W. Saunders, Jr., CFA, appears here.]

MARKET CONDITIONS AND PERFORMANCE
This past six months reporting period ending January 31, 1998, includes the best
bond market we have seen in the past two years.  Interest  rates for the 30-year
U.S. Treasury bond,(1) as shown on the chart below,   declined  from  6.30%   on
July 31, 1997, to 5.86% on January 30, 1998.  I  am  pleased to report that your
Fund has  performed  very well for this  period.  In fact, for the latest twelve
months ending January 31, 1998, your Fund's total return of 12.17% ranked number
9 out of 140 funds in the Lipper(2) Corporate Debt A-Rated Bond Fund category in
which the Fund's performance is measured.(3)

PORTFOLIO
The Federal  Reserve  appears  comfortable  with the outlook that inflation will
remain low,  and  this  has calmed  the  bond market.  In  this more  hospitable
environment, we made some changes in the portfolio.  Our common stock  holdings,
primarily electric  utilities which are sensitive to  changes in interest rates,
were sold when their appreciating  prices made their  dividend  yields fall well
below those available in bonds and preferred   stocks.   Additional  investments
were made in Real Estate Investment  Trust  (REIT)  preferred  stocks  at   very
attractive dividend yields.   We also  increased   our   position  in  long U.S.
Treasury  bonds  while reducing our holdings in  agency  mortgage   pass-through
securities (FHLMC, FNMA, and GNMA).  As  of January 31, 1998, the portfolio mix,
as percentages of the net assets,  was  29.6% in  U.S. Treasury bonds,  54.5% in
agency mortgages pass-through securities, 7.5%  in  corporate bonds, and 7.6% in
preferred stocks.

30-YEAR U.S TREASURY BOND YIELD
- ---------------------------------


A chart in the form of a line graph appears here,  illustrating the yield of the
30-Year U.S.  Treasury  Bond from  7/31/97 to 1/30/98.  The data points from the
graph are as follows:



  30 YEAR U.S. TREASURY BOND YIELD

   7/31/97                6.30%
   8/15/97                6.58%
   8/29/97                6.64%
   9/15/97                6.60%
   9/30/97                6.43%
   10/15/97               6.43%
   10/31/97               6.18%
   11/14/97               6.18%
   11/28/97               6.12%
   12/15/97               6.05%
   12/31/97               5.99%
   1/15/98                5.79%
   1/30/98                5.86%


(1) The 30-year U.S. Treasury Bond is generally   considered  the  benchmark for
U.S. long-term  interest  rates.

(2) Lipper  Analytical  Services  is an  independent organization  that monitors
the  performance  of mutual funds.

(3) For the 5- and 10-year  periods ending January 31, 1998, the Fund ranked  11
out of 60 and 3 out of 36, respectively.  Returns  for  the  one, five, and ten-
year  periods ending January 31, 1998, respectively,  are listed on page 4.



OUTLOOK
The financial press is full of predictions about the expected negative impact on
the U.S.  economy which will result from the currency and financial  market woes
in Asia. The Asian deflation makes imports to the U.S. less costly,  in contrast
with now higher priced U.S.  exports to Asia,  thus  aggravating  our balance of
trade deficit.  Implications for the bond market are positive.  A deepening U.S.
trade  deficit,  together  with a shrinking  U.S.  budget  deficit,  produces an
interesting  supply/demand  relationship for U.S. Treasury securities.  If there
are more U.S. dollars in Asian hands, and less of a need by the U.S. Treasury to
issue securities,  then this could cause prices for U.S. Treasury  securities to
rise (declining  interest rates) because of strong demand versus smaller supply.
Inflation in the U.S. continues in a downtrend, and this can also lower interest
rates.  In any event,  the potential for rising interest rates appears to be low
for the time being. We will continue to seek a high level of income for the Fund
to  enhance  the   compounding   of  potential   returns  which  accrue  through
reinvestment of income.

INCOME FUND
NOTES TO FINANCIAL STATEMENTS

January 31, 1998
(Unaudited)

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
USAA MUTUAL FUND, INC. (the Company),  registered  under the Investment  Company
Act of 1940,  as  amended,  is a  diversified,  open-end  management  investment
company  incorporated  under the laws of  Maryland  consisting  of ten  separate
funds. The information  presented in this semiannual report pertains only to the
Income Fund (the  Fund).  The Fund's  investment  objective  is maximum  current
income without undue risk to principal.  USAA Investment Management Company (the
Manager)  seeks to  achieve  this  objective  by  investing  the  Fund's  assets
primarily in U.S.  dollar-denominated  securities that have high yields relative
to the risk involved.

A.  Security  valuation - The value of each  security is  determined  (as of the
close of  trading  on the New  York  Stock  Exchange  on each  business  day the
Exchange is open) as set forth below:

1. Debt and  government  securities  are valued each  business  day by a pricing
service (the Service) approved by the Company's Board of Directors.  The Service
uses the mean  between  quoted  bid and asked  prices or the last sale  price to
price  securities  when,  in the Service's  judgement,  these prices are readily
available and are  representative  of the  securities'  market values.  For many
securities,  such prices are not readily available. The Service generally prices
these  securities  based on methods  which  include  consideration  of yields or
prices  of  securities  of  comparable  quality,   coupon,  maturity  and  type,
indications  as to  values  from  dealers  in  securities,  and  general  market
conditions.

2.  Portfolio  securities,  except as  otherwise  noted,  traded  primarily on a
domestic  securities  exchange  are  valued  at the  last  sales  price  on that
exchange.

3.  Over-the-counter  securities  are priced at the last sales  price or, if not
available, at the average of the bid and asked prices.

4.  Securities  purchased  with  maturities  of 60 days or less  are  stated  at
amortized cost which approximates market value.

5.  Securities  which cannot be valued by the methods set forth  above,  and all
other assets,  are valued in good faith at fair value,  using methods determined
by the Manager under the general supervision of the Board of Directors.

B. Federal taxes - The Fund's policy is to comply with the  requirements  of the
Internal  Revenue Code  applicable  to  regulated  investment  companies  and to
distribute  substantially all of its income to its shareholders.  Therefore,  no
federal  income or excise  tax  provision  is  required.  As a result of certain
permanent  differences between book and tax basis accounting,  reclassifications
have been made on the statement of assets and  liabilities  to decrease  paid-in
capital by $6,773,  increase accumulated  undistributed net investment income by
$4,880, and increase accumulated net realized gain on investments by $1,893.

C.  Investments in securities - Security  transactions  are accounted for on the
date the securities are purchased or sold (trade date).  Gain or loss from sales
of investment  securities  is computed on the  identified  cost basis.  Dividend
income is recorded on the  ex-dividend  date;  interest  income  is  recorded on
the  accrual  basis.   Discounts  and  premiums  on  short-term  securities  are
amortized over the life of the  respective  securities.  Amortization  of market
discounts  on  long-term  securities  is  recognized  as  interest  income  upon
disposition of the security to the extent there is a gain on disposition.

D. Use of estimates - The preparation of financial statements in conformity with
generally accepted  accounting  principles requires management to make estimates
and  assumptions   that  may  affect  the  reported  amounts  in  the  financial
statements.


(2)  LINES OF CREDIT
The Fund  participates  with other USAA funds in two joint short-term  revolving
loan  agreements  totaling  $850  million,  one with  USAA  Capital  Corporation
(CAPCO),  an affiliate of the Manager ($750 million  uncommitted),  and one with
NationsBank  of  Texas,  N.A.  ($100 million committed).  The  purpose  of   the
agreements is to meet temporary or emergency cash needs,   including  redemption
requests  that might  otherwise  require the untimely disposition of securities.
Subject to availability under its agreement with  CAPCO,   the  Fund may  borrow
from  CAPCO an amount up to 5% of the Fund's total assets  at CAPCO's  borrowing
rate  with  no  markup.   Subject  to  availability  under  its  agreement  with
NationsBank,  the Fund may borrow from  NationsBank an amount which,  when added
to outstanding borrowings  under the CAPCO agreement, does not exceed 25% of the
Fund's total assets at NationsBank's borrowing rate plus a markup.  The Fund had
no borrowings under either of these agreements during the six-month period ended
January 31, 1998.


(3)  DISTRIBUTIONS
Distributions  of net  investment  income  are made  monthly.  Distributions  of
realized gains from security  transactions not offset by capital losses are made
in the succeeding  fiscal year or as otherwise  required to avoid the payment of
federal taxes.


(4)  INVESTMENT TRANSACTIONS
Purchases and sales of  securities,  excluding  short-term  securities,  for the
six-month  period ended  January 31, 1998 were  $382,581,699  and  $349,423,456,
respectively.

Gross unrealized  appreciation and depreciation of investments as of January 31,
1998 was $92,948,051 and $2,898,734, respectively.


(5)  TRANSACTIONS WITH MANAGER
A. Management fees - The investment policies of the Fund and management of   the
Fund's  portfolio are carried out by USAA  Investment  Management  Company.  The
Fund's management fees are computed at .24% of its annual average net assets.

B. Transfer agent's fees - USAA Transfer Agency Company,  d/b/a USAA Shareholder
Account Services, an affiliate of the Manager,  provides transfer agent services
to the Fund  based on an  annual  charge  of $26 per  shareholder  account  plus
out-of-pocket expenses.

C.  Underwriting  services - The Manager  provides  exclusive  underwriting  and
distribution  of the Fund's  shares on a  continuing  best  efforts  basis.  The
Manager receives no commissions or fees for this service.

D. Brokerage Services - USAA Brokerage Services, a discount brokerage service of
the Manager,  may execute  portfolio  transactions  for the Fund.  The amount of
brokerage  commissions  paid to USAA  Brokerage  Services  during the  six-month
period ended January 31, 1998 was $19,200.


(6)  TRANSACTIONS WITH AFFILIATES
USAA Investment Management Company is indirectly wholly owned by United Services
Automobile  Association  (the  Association),   a  large,  diversified  financial
services  institution.  At January 31, 1998, the  Association and its affiliates
(including  related employee  benefit plans) owned 23,512,237  shares (17.4%) of
the Fund.

Certain directors and officers of the Fund are also directors,  officers, and/or
employees  of the Manager.  None of the  affiliated  directors or Fund  officers
received compensation from the Fund.
