Dear Shareholder:

We are pleased to provide the annual report for the Smith Barney Natural
Resources Fund Inc. ("Fund") for the year ended October 31, 1998. In this report
we have summarized the period's prevailing economic and market conditions and
outlined the Fund's investment strategy. A detailed summary of performance and
current holdings can be found in the appropriate sections that follow.

Performance Update

The Natural Resources Fund seeks long-term capital appreciation by investing
primarily in natural resource investments. For the year ended October 31, 1998,
the Fund posted a negative total return of 28.13% for Class A shares. In
comparison, the Fund's Lipper Analytical Services, Inc. peer group generated a
negative total return of 26.60% for the same period. (Lipper is a major fund
tracking organization.)

A Specialty Series Fund

The Natural Resources Fund is part of the Specialty Series of Smith Barney
Mutual Funds. Specialty Series mutual funds explore opportunities in a narrower
sector of the market or by using a narrower investment focus.

Economic and Market Update

All natural resources funds have been challenged so far in 1998 by the bear
market in the natural resources industry caused, in our view, primarily by
economic crises in developing markets around the world. The crises started with
the collapse of the Thai baht in July of 1997 and spread quickly from there to
Indonesia, Singapore, Taiwan, Malaysia and Hong Kong. China and Japan did not
experience currency crises, but their economies were affected by the region's
chaos. By early this year, fears of similar turmoil spread to all of the world's
regions including South America, the former Soviet Union, etc., and even the
developed nations in North America and Europe.

Investors correctly perceived these events as negative for the natural resource
industry, which depend on economic activity for growth in demand. In fact,
virtually every natural resource industry has been involved in a bear market
since the Asian crisis began in earnest last October. Yet, the downdraft reached
what appears to be a climactic end in August, with resource stocks down 50%-70%,
and in many cases selling at valuation levels not seen in the last fifteen
years.

In response to the poor performance of natural resource stocks and because we
thought this mediocre performance would continue, we raised the Fund's cash
position to 35% and held this cash position throughout August. In September,
with many natural resource stocks selling at very low historic levels, we became
fully invested. Raising such large levels of cash has not been how we have
normally managed the Fund in the past. Yet, even the most casual observer would
admit that this past year has not been a "normal" one for natural resources.

Since the end of August, natural resource stocks have performed better, and the
Fund has rebounded as well. Since its low of $13.76 per share on August 31,
1998, the Fund's net asset value ("NAV") has increased by 20.35% to $16.56 on
October 31, 1998 for Class A shares. As we will discuss in the next section of
this letter, we think that natural resource stocks have reached a major cyclical
bottom, and are likely to experience better performance over the next 12 to 18
months.

We are committed to finding the companies that we believe are the best
positioned to benefit from the eventual upturn. In some cases, that may mean the
largest companies in a particular industry. In other cases, it may involve
smaller-sized companies that are well-positioned to succeed in a specific market
niche. In all cases, it will involve buying these companies at historically low
valuations. The current market environment offers great opportunities in this
regard.

Market Outlook

During the reporting period, many natural resource stocks reached valuation
levels not seen since the recessions of 1981-1982 or 1990-1992. Many stocks in
the group are currently trading at or below book value, and many have dividend
yields of 4% to 5% or more, compared with an average yield of roughly 1.5% for
the S&P 500 as of the end of October.

While the immediate future is always difficult to predict, we think these
valuation levels offer an attractive starting point for long-term investors who
are interested in the opportunities presented by natural resource industries. In
our opinion, as the world's economies eventually recover from the shocks of the
past year, growth should reaccelerate in many parts of the world. When this
happens, natural resource stocks should have tremendous earnings leverage.

A section follows on page four entitled "Opportunities in the Paper Industry"
where we discuss in greater detail why we think select paper company stocks are
attractive.

The last year has been a difficult one for the Fund. Yet, we are convinced that
the worst may be behind us and that patient long-term investors who seek capital
appreciation and who can tolerate significant short-term volatility should
ultimately be rewarded. We encourage you to visit our improved Web site at
www.smithbarney.com. Thank you for your investment in the Smith Barney Natural
Resources Fund. We look forward to helping you pursue your investment goals in
the years ahead.

Sincerely,

Opportunities in the Paper Industry

One of the more interesting developments in the natural resource industries
lately has been the voluntary and involuntary reduction of capital spending that
is occurring virtually across the board. In the developed countries, capital
expenditures are being reduced because of lower cash flows, and also because
many managers have become more focused on improving the returns on the capital
employed in their business. In the developing world, where many investments
over the last several years may have been made with little regard to the returns
they would generate, the events of the past year are forcing similar spending
cuts.

We think that these spending cuts are the seeds from which the next industry
upturns will sprout. Demand in many of these industries grows steadily over time
- -- supply growth is the variable that changes substantially throughout the
business cycle. The next time demand recovers it will meet less new supply in
many industries than has been the case in previous economic recoveries. This
should make for powerful improvements in profitability in these industries.

Nowhere is this more true than in the paper industry, which is very capital
intensive. In the last two years, we have seen significant consolidation within
this industry, creating the possibility of capacity reduction in several paper
grades. In addition, one of the byproducts of the Asian crisis has been the
cancellation of numerous projects scheduled to be built in the region. Over the
next two years, the paper industry is planning to add less new papermaking
capacity than at any time since the 1940s.

Paper stocks tend to trade in anticipation of announced price changes.
Currently, prices are weak, and they may head lower in the next few months.
However, if demand stabilizes, we expect the conditions described above to cause
prices to reach bottom levels relatively soon and go higher thereafter.

We believe that paper stocks, having reached valuation levels similar to those
last seen in the recession of 1990-1992, offer attractive risk/reward tradeoffs.
As of October 31, 1998, the Fund holds roughly a 14% position in the paper
industry, and will likely use any sell off in the group to add to our position.
The Fund's largest paper industry holdings at the present time are Georgia
Pacific Corporation, Weyerhauser Corporation, Union Camp Corporation, Champion
International and Jefferson Smurfit Corporation.

+    Hypothetical illustration of $10,000 invested in Class A shares on October
     31, 1988, assuming deduction of the maximum 5.00% sales charge at the time
     of investment and the reinvestment of dividends and capital gains, if any,
     at net asset value through October 31, 1998. The Morgan Stanley Capital
     International World Index ("MSCI World Index") is an arithmetic average
     weighted by the market value performance of 1,468 securities listed on the
     stock exchanges of the USA, Europe, Canada, Australia, New Zealand and the
     Far East. The Standard & Poor's 500 Index is an index composed of widely
     held common stocks listed on the New York Stock Exchange, American Stock
     Exchange and the over-the-counter market. Figures for the index include the
     reinvestment of dividends. The indexes are unmanaged and not subject to the
     same management and trading expenses as a mutual fund. The performance of
     the Fund's other classes may be greater or less than the Class A shares'
     performance indicated on this chart, depending on whether greater or lesser
     sales charges and fees were incurred by shareholders investing in the other
     classes.

     All figures represent past performance and are not a guarantee of future
     results. Investment returns and principal value will fluctuate, and
     redemption values may be more or less than the original cost. No adjustment
     has been made for shareholder tax liability on dividends or capital gains.

1. Significant Accounting Policies

Smith Barney Natural Resources Fund Inc. ("Fund"), a Maryland corporation, is
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company.

The significant accounting policies followed by the Fund are: (a) security
transactions are accounted for on trade date; (b) securities traded in national
securities markets are valued at the closing prices in the primary exchange on
which they are traded; securities listed or traded on certain foreign exchanges
or other markets whose operations are similar to the U.S. over-the-counter
market (including securities listed on exchanges where the primary market is
believed to be over-the-counter) and securities for which no sale was reported
on that date are valued at the mean between the bid and ask prices. Securities
which are listed or traded on more than one exchange or market are valued at the
quotations on the exchange or market determined to be the primary market for
such securities. Gold bullion is valued at the daily London afternoon fixing;
(c) securities for which market quotations are not available will be valued in
good faith at fair market value by or under the direction of the Board of
Trustees; (d) securities maturing within 60 days are valued at cost plus
accreted discount, or minus amortized premium, which approximates value; (e) the
accounting records of the Fund are maintained in U.S. dollars. All assets and
liabilities denominated in foreign currencies are translated into U.S. dollars
based on the rate of exchange of such currencies against U.S. dollars on the
date of valuation. Purchases and sales of securities, and income and expenses 
are translated at the rate of exchange quoted on the respective date that such
transactions are recorded. Differences between income or expense amounts
recorded and collected or paid are adjusted when reported by the custodian; (f)
interest income, adjusted for amortization of premium and accretion of discount,
is recorded on an accrual basis; (g) dividend income is recorded on the ex-
dividend date; foreign dividends are recorded on the ex-dividend date or as soon
as practical after the Fund determines the existence of a dividend declaration
after exercising reasonable due diligence; (h) dividends and distributions to
shareholders are recorded on the ex-dividend date; (i) gains or losses on the
sale of securities are calculated by using the specific identification method;
(j) direct expenses are charged to each class; management fees and general
expenses are allocated on the basis of relative net assets; (k) the character of
income and gains to be distributed are determined in accordance with income tax
regulations which may differ from generally accepted accounting principles. At
October 31, 1998, reclassifications were made to the Fund's capital accounts to
reflect permanent book/tax differences and income and gains available for
distributions under income tax regulations. Accordingly, a portion of
overdistributed net investment income amounting to $459,457 and accumulated net
realized gain of $14 was reclassified

to paid-in capital. Net investment income, net realized gains and net assets
were not affected by this adjustment; (l) the Fund intends to comply with the
requirements of the Internal Revenue Code of 1986, as amended, pertaining to
regulated investment companies and to make distributions of taxable income
sufficient to relieve it from substantially all Federal income and excise taxes;
and (m) estimates and assumptions are required to be made regarding assets,
liabilities and changes in net assets resulting from operations when financial
statements are prepared. Changes in the economic environment, financial markets
and any other parameters used in determining these estimates could cause actual
results to differ.

In addition, the Fund may enter into forward exchange contracts in order to 
hedge against foreign currency risk. These contracts are marked-to-market daily,
by recognizing the difference between the contract exchange rate and the current
market rate as an unrealized gain or loss. Realized gains or losses are
recognized when contracts are settled.

2. Management Agreement and Other Transactions

Mutual Management Corp. ("MMC"), a subsidiary of Salomon Smith Barney Holdings
Inc. ("SSBH"), acts as investment manager to the Fund. The Fund pays MMC a
management fee calculated at an annual rate of 0.75% of the average daily net
assets. This fee is calculated daily and paid monthly.

On October 8, 1998, CFBDS, Inc. became the Fund's distributor. Prior to that
date Salomon Smith Barney Inc. ("SSB"), another subsidiary of SSBH, was the
Fund's distributor. SSB (as well as certain other broker-dealers) continues to
sell Fund shares to the public as a member of the selling group.

SSB acts as the primary broker for its portfolio agency transactions. For the
year ended October 31, 1998, SSB received brokerage commissions of $14,131.

On June 12, 1998, the Fund's existing Class C shares were renamed Class L
shares. Effective June 15, 1998, Class L shares are being sold at net asset 
value plus a maximum initial sales charge of 1.00%. Class L shares also have a
1.00% contingent deferred sales charge ("CDSC"), which applies if redemption
occurs within the first year of purchase.

There is also a CDSC of 5.00% on Class B shares, which applies if redemption
occurs within one year from initial purchase and declines thereafter by 1.00%
per year until no CDSC is incurred.

4. Futures Contracts

Initial margin deposits made upon entering into futures contracts are recognized
as assets. Securities equal to the initial margin amount are segregated by the
custodian in the name of the broker. Additional securities are also segregated
up to the current market value of the futures contract. During the period the
futures contract is open, changes in the value of the contract are recognized as
unrealized gains or losses by "marking to market" on a daily basis to reflect
the market value of the contract at the end of each day's trading. Variation
margin payments are received or made and recognized as assets due from or
liabilities due to broker, depending upon whether unrealized gains or losses are
incurred. When the contract is closed, the Fund records a realized gain or loss
equal to the difference between the proceeds from (or cost of) the closing
transaction and the Fund's basis in the contract.

The Fund enters into such contracts to hedge a portion of its portfolio. The
Fund bears the market risk that arises from changes in the value of the
financial instruments and securities indices (futures contracts).

At October 31, 1998, there were no open futures contracts.

5. Options Contracts

Premiums paid when put or call options are purchased by the Fund, represent
investments, which are marked-to-market daily and are included in the schedule
of investments. When a purchased option expires, the Fund will realize a loss in
the amount of the premium paid. When the Fund enters into a closing sales
transaction, the Fund will realize a gain or loss depending on whether the
proceeds from the closing sales transaction are greater or less than the premium
paid for the option. When the Fund exercises a put option, it will realize a
gain or loss from the sale of the underlying security and the proceeds from such
sale will be decreased by the premium originally paid. When the Fund exercises a
call option, the cost of the security which the Fund purchases upon exercise
will be increased by the premium originally paid.

At October 31, 1998, the Fund had no open purchased call option contracts and
one open purchased put option with a total cost of $64,000.

Notes to Financial Statements (continued)
================================================================================

When the Fund writes a covered call or put option, an amount equal to the 
premium received by the Fund is recorded as a liability, the value of which is
marked-to-market daily. When a written option expires, the Fund realizes a gain
equal to the amount of the premium received. When the Fund enters into a closing
purchase transaction, the Fund realizes a gain or loss depending upon whether
the cost of the closing transaction is greater or less than the premium
originally received, without regard to any unrealized gain or loss on the
underlying security, and the liability related to such option is eliminated.
When a written call option is exercised, the cost of the security sold will be
decreased by the premium originally received. When a written put option is
exercised, the amount of the premium originally received will reduce the cost of
the security which the Fund purchased upon exercise. When written index options
are exercised, settlement is made in cash. The risk associated with purchasing
options is limited to the premium originally paid. The Fund enters into options
for hedging purposes. The risk in writing a covered call option is that the Fund
gives up the opportunity to participate in any increase in the price of the
underlying security beyond the exercise price. The risk in writing a put option
is that the Fund is exposed to the risk of loss if the market price of the
underlying security declines.

The following covered call option transactions occurred during the year ended
October 31, 1998:

                                                            Number of

6. Lending of Portfolio Securities

The Fund has an agreement with its custodian whereby the custodian may lend
securities owned by the Fund to brokers, dealers and other financial
organizations. Fees earned by the Fund on securities lending are recorded as
interest income. Loans of securities by the Fund are collateralized by cash, 
U.S. government securities or high quality money market instruments that are
maintained at all times in an amount at least equal to the current market value
of the loaned securities, plus a margin depending on the type of securities
loaned. The custodian establishes and maintains the collateral in a segregated
account. The Fund maintains exposure for the risk of any losses in the
investment of amounts received as collateral.

At October 31, 1998, the Fund loaned common stock having a value of $4,636,144
and holds the following collateral for loaned securities:

7. Repurchase Agreements

The Fund purchases (and its custodian takes possession of) U.S. government
securities from banks and securities dealers subject to agreements to resell the
securities to the sellers at a future date (generally, the next business day) at
an agreed upon higher repurchase price. The Fund requires continual maintenance
of the market value of the collateral in amounts at least equal to the
repurchase price.

8. Concentration of Risk

The Fund's investments in foreign securities may involve risks not present in
domestic investments. Since securities may be denominated in a foreign currency
and may require settlement in foreign currencies and pay interest or dividends
in foreign currencies, changes in the relationship of these foreign currencies
to the U.S. dollar can significantly affect the value of these investments and
earnings of the Fund. Foreign investments may also subject the Fund to foreign
government exchange restrictions, expropriation, taxation or other political,
social or economic developments, all of which could affect the market and/or
credit risk of the investments.

The Fund also intends to invest at least 65% of its assets in natural resource-
related investments. As a result of this concentration policy, which is a
fundamental policy of the Fund, the Fund's investment may be subject to greater
risk and market fluctuation than a fund that invests in securities representing
a broader range of investment alternatives.

9. Capital Loss Carryforward

At October 31, 1998, the Fund had, for Federal income tax purposes,
approximately $15,192,000 of capital loss carryforwards available to offset any
future realized capital gains. To the extent that these carryforward losses are
used to offset capital gains, it is probable that the gains so offset will not
be distributed. The amount and year of the expiration for each carryforward loss
is indicated below:

                                      10/31/99      10/31/00        10/31/06
================================================================================
Carryforward Amounts                 $1,000,000    $1,320,000      $12,872,000
================================================================================

10. Capital Shares

At October 31, 1998, the Fund had three billion shares of capital stock
authorized with a par value of $0.001 per share. The Fund has the ability to
issue multiple classes of shares. Each share of a class represents an identical
interest in the Fund and has the same rights, except that each class bears
certain expenses specifically related to the distribution of its shares.
Effective June 12, 1998, the Fund adopted the renaming of existing Class C
shares as Class L shares.

Independent Auditors' Report
================================================================================

The Shareholders and Board of Directors of
Smith Barney Natural Resources Fund Inc.:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Smith Barney Natural Resources Fund Inc. as
of October 31, 1998, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the years in the two-
year period then ended, and the financial highlights for each of the years in
the four-year period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits. The financial highlights for the year ended October 31,
1994 were audited by other auditors whose report thereon, dated December 29,
1994, expressed an unqualified opinion on those financial highlights.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of
October 31, 1998, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Smith
Barney Natural Resources Fund Inc. as of October 31, 1998, and the results of
its operations for the year then ended, the changes in its net assets for each
of the years in the two-year period then ended, and the financial highlights for
each of the years in the four-year period then ended, in conformity with
generally accepted accounting principles.
