Semi-Annual Report
October 31, 1997

Washington Mutual Investors Fund seeks to  provide income  and growth of
principal through quality common stocks.

THE FIGURES IN THIS REPORT REFLECT PAST RESULTS AND ARE NOT PREDICTIVE OF
FUTURE RESULTS. FUND RESULTS IN THIS REPORT WERE CALCULATED WITHOUT A SALES
CHARGE. SHARE PRICE AND RETURN WILL VARY, SO YOU MAY LOSE MONEY BY
INVESTING IN THE FUND. THE SHORTER THE TIME PERIOD OF YOUR INVESTMENT, THE
GREATER THE POSSIBILITY OF LOSS. FUND SHARES ARE NOT DEPOSITS OR
OBLIGATIONS OF, OR INSURED OR GUARANTEED BY, THE U.S. GOVERNMENT, ANY
FINANCIAL INSTITUTION, THE FEDERAL DEPOSIT INSURANCE CORPORATION, OR ANY
OTHER AGENCY, ENTITY OR PERSON.

FELLOW SHAREHOLDERS:

     The first half of our fiscal year - the six months ended October 31 -
was marked by further economic expansion in the United States and by a
selloff in stock prices around the world.  The decline began in Asia this
past summer and spread to Europe and the U.S.  It was followed, in this
country, by a recovery in which prices fluctuated sharply and ended the
period below their 1997 peak, but still relatively high by historical
standards.

     In this environment, Washington Mutual recorded a sizeable gain.  For
the six months, the value of an investment in the Fund rose 17.6% versus a
15.1% increase for the unmanaged Standard & Poor's 500 Composite Stock
Index, both including reinvestment.  It is worth noting that during the
October slide (from the high recorded on October 7 to the low on October
27), the S&P 500 fell 10.8% while the Fund's share value went down 7.7%.
     The selloff removed some of the euphoria that had surrounded the
market and focused investor attention on possible repercussions of the
decline in commodity and other prices taking place in the economies of a
number of Asian countries.  While this deflationary trend is certainly a
legitimate concern, we believe the conservative nature of Washington
Mutual's portfolio of U.S. stocks - with its emphasis on dividend income
and relatively low price-to-earnings ratios - should continue to help
cushion the Fund if there is further market volatility in the period ahead.

     As a counterpoint to the negative news coming from overseas, it should
be mentioned that the United States is currently enjoying the most
favorable business conditions in many years, with growth continuing at a
steady pace, unemployment lower than at any time since 1973 and inflation
at the lowest level in more than a decade.

     The portfolio in this report shows ownership of 151 companies in 27
industries.  On October 31, the largest industry positions as a percentage
of net assets were Banking (14.7%), Health & Personal Care (11.7%), Energy
Sources (10.4%), Telecommunications (8.7%), Electric & Gas Utilities
(8.1%), and Insurance (6.0%).

     Seven new company names have appeared in the portfolio since July 31:
American Stores, Enova, GPU, International Flavors & Fragrances, Johnson
Controls, Solutia (spun off from Monsanto Company), and Willamette
Industries.  Two holdings were eliminated: Northeast Utilities and
Whirlpool. Again this year, changes in your Fund's portfolio have resulted
in substantial capital gains.  To avoid payment of Federal excise taxes,
these gains will be distributed to shareholders, together with an extra
income payment, prior to December 31st.  Because long-term capital gain
taxes were reduced this past summer, a portion of the distribution will
qualify for the new lower 20% rate.  All shareholders subject to Federal
income tax will receive a Form 1099 containing final details in late
January.

     Your questions and comments will, as always, be most welcome.
Cordially,

Notes to Financial Statements Unaudited

1.   Washington Mutual Investors Fund (the "Fund") is registered under the
Investment Company Act of 1940 as an open-end, diversified management
investment company.  The Fund's investment objective is to produce income
and to provide an opportunity for growth of principal consistent with sound
common stock investing.  The following paragraphs summarize the significant
accounting policies consistently followed by the Fund in the preparation of
its financial statements:

          Investment securities are stated at market value based upon
     closing sales prices reported on a national securities exchange on the
     day of valuation or, for listed securities having no sales reported,
     upon last-reported bid prices on that date.  Treasury bills with
     original or remaining maturities in excess of 60 days are valued at
     the mean of their quoted bid and asked prices obtained from a major
     dealer in short-term securities.  Treasury bills with 60 days or less
     to maturity are valued at amortized cost, which approximates market
     value.  Securities for which representative market quotations are not
     readily available are valued at fair value as determined in good faith
     under policies approved by the Fund's Board.

          As is customary in the mutual fund industry, securities
     transactions are accounted for on the date the securities are
     purchased or sold.  Realized gains and losses from securities
     transactions are reported on an identified cost basis.  Dividend and
     interest income is reported on the accrual basis.  Dividends and
     distributions paid to shareholders are recorded on the ex-dividend
     date.

2.   It is the Fund's policy to continue to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and
to distribute all of its net taxable income, including any net realized
gain on investments, to its shareholders.  Therefore, no federal income tax
provision is required.

     As of October 31, 1997, net unrealized appreciation on investments for
book and federal income tax purposes aggregated $12,331,709,000, of which
$12,498,841,000 related to appreciated securities and $167,132,000 related
to depreciated securities.  There was no difference between book and tax
realized gains on securities transactions for the six months ended October
31, 1997.  The cost of portfolio securities for book and federal income tax
purposes was $22,976,602,000 at October 31, 1997.

3.    Officers of the Fund received no remuneration from the Fund in such
capacities.  Their remuneration was paid by Washington Management
Corporation (WMC), a wholly owned subsidiary of The Johnston-Lemon Group,
Incorporated.  WMC, business manager of the Fund, was paid a fee of
$17,474,000 for business management services.  The business management
agreement provides for monthly fees, accrued daily, based on an annual rate
of 0.175% of the first $3 billion of net assets; 0.15% of such assets in
excess of $3 billion but not exceeding $5 billion; 0.135% of such assets in
excess of $5 billion but not exceeding $8 billion; 0.12% of such assets in
excess of $8 billion but not exceeding $12 billion; 0.095% of such assets
in excess of $12 billion but not exceeding $21 billion; 0.075% of such
assets in excess of $21 billion but not exceeding $34 billion; and 0.06% of
net assets in excess of $34 billion.  Under this agreement all expenses
chargeable to the Fund, including compensation to the business manager,
shall not exceed 1% of the average net assets of the Fund on an annual
basis.  Johnston, Lemon & Co. Incorporated, a wholly owned subsidiary of
The Johnston-Lemon Group, Incorporated, has informed the Fund that it has
earned $488,000 on its retail sales of shares and under the distribution
plan of the Fund but received no net brokerage commissions resulting from
purchases and sales of securities for the investment account of the Fund.
All officers of the Fund and five of its directors are affiliated with The
Johnston-Lemon Group, Incorporated.  Capital Research and Management
Company, investment manager of the Fund, was paid a fee of $33,712,000 for
investment management services.  The investment advisory agreement provides
for monthly fees, accrued daily, based on an annual rate of 0.225% of the
first $3 billion of net assets; 0.21% of such assets in excess of $3
billion but not exceeding $8 billion; 0.20% of such assets in excess of $8
billion but not exceeding $21 billion; 0.195% of such assets in excess of
$21 billion but not exceeding $34 billion; and 0.19% of net assets in
excess of $34 billion.

     Pursuant to a Plan of Distribution, the Fund may expend up to 0.25% of
its average net assets annually for any activities primarily intended to
result in sales of Fund shares, provided the categories of expenses for
which reimbursement is made are approved by the Fund's Board of Directors.
Fund expenses under the Plan include payments to dealers to compensate them
for their selling and servicing efforts and reimbursements to American
Funds Distributors, Inc. (AFD), the principal underwriter of the Fund's
shares, for its activities and expenses related to the sales of Fund shares
or servicing of shareholder accounts.  During the six months ended October
31, 1997, distribution expenses under the Plan were $39,000,000, including
accrued and unpaid expenses of $11,737,000.
     AFD has informed the Fund that it has received $15,913,000 (after
allowances to dealers) as its portion of the sales charges paid by
purchasers of the Fund's shares.  Such sales charges are not an expense of
the Fund and, hence, are not reflected in the accompanying Statement of
Operations.

     American Funds Service Company, the transfer agent for the Fund, was
paid a fee of $9,287,000.

     Directors and Advisory Board members of the Fund who are unaffiliated
with WMC may elect to defer part or all of the fees earned for such
services.  Amounts deferred are not funded and are general unsecured
liabilities of the Fund.  As of October 31, 1997, aggregate amounts
deferred and earnings thereon were $328,000.

4.    As of October 31, 1997, accumulated undistributed net realized gain
on investments was $1,954,792,000 and additional paid-in capital was
$19,678,764,000.

     The Fund made purchases and sales of investment securities, excluding
short-term securities, of $4,656,001,000 and $2,696,533,000, respectively,
during the six months ended October 31, 1997.

     Pursuant to the custodian agreement, the Fund receives credits against
its custodian fee for imputed interest on certain balances with the
custodian bank.  The custodian fee of $178,000 included $37,000 that was
paid by these credits rather than in cash.

     The Fund owns 5.4% of the outstanding voting securities of Westvaco
Corp. and thus is considered an affiliate as defined in the Investment
Company Act of 1940.
