        Pursuant to the requirements of the Securities and

                            Thrift Plan for Employees of
                            Conoco Inc.

                REPORT OF INDEPENDENT ACCOUNTANTS


     To the Participants of the Thrift Plan for Employees of
 Conoco Inc. and the Employee Benefit Plans Board of Conoco Inc.



        In our opinion, the financial statements listed in the 
accompanying index present fairly, in all material respects, the 
net assets available for plan benefits of the Thrift Plan for 
Employees of Conoco Inc. (the "Plan") at December 31, 1997 and 
1996, and the changes in net assets available for Plan benefits 
for the years then ended, in conformity with generally accepted 
accounting principles.  These financial statements are the 
responsibility of the Plan Administrator; our responsibility is 
to express an opinion on these financial statements based on our 
audits.  We conducted our audits of these statements in 
accordance with generally accepted auditing standards which 
require that we plan and perform the audit to obtain reasonable 
assurance about whether the financial statements are free of 
material misstatement.  An audit includes examining, on a test 
basis, evidence supporting the amounts and disclosures in the 
financial statements, assessing the accounting principles used 
and significant estimates made by the Plan Administrator, and 
evaluating the overall financial statement presentation.  We 
believe that our audits provide a reasonable basis for the 
opinion expressed above.

        Our audits were performed for the purpose of forming an 
opinion on the basic financial statements taken as a whole.  The 
additional information included in Schedules I and II is not a 
required part of the basic financial statements but is addi- 
tional information required by ERISA.  The Fund Information in 
the statements of net assets available for benefits and the 
statements of changes in net assets available for benefits is 
presented for purposes of additional analysis rather than to 
present the net assets available for plan benefits and changes 
in net assets available for plan benefits of each fund.  
Schedules I and II and the Fund Information have been subjected 
to the auditing procedures applied in the audits of the basic 
financial  statements and, in our opinion, are fairly stated in 
all material respects in relation to the basic financial 
statements taken as a whole.

                            (Dollars in Thousands)

NOTE 1  --  DESCRIPTION OF THE THRIFT PLAN:

        The following description of the Thrift Plan for Employees of Conoco 
Inc. (the "Plan") provides only general information.  Members should refer to 
the Plan document for the Plan's provisions.

  THE PLAN

        The Plan is a defined contribution plan which was established in 1952 
by Conoco Inc. (the "Company"), which became a wholly-owned subsidiary of
E. I. du Pont de Nemours and Company (DuPont) in 1981.  The Plan is subject to 
the provisions of the Employee Retirement Income Security Act of 1974 (ERISA) 
and the Internal Revenue Code (the "Code").

        The purpose of the Plan is to encourage employees to save 
systematically a portion of their current compensation and to assist them to 
accumulate additional means for the time of their retirement.  The Plan is a 
tax-qualified, contributory profit sharing plan.  Employees of the Company, 
including employees of Affiliated Companies that have adopted the Plan, who 
have previously met the eligibility requirements of the Plan or who have 
completed a designated period of 12 consecutive months during which they 
complete 1,000 hours or more of service; who are regular, full time employees 
and have completed at least one year of continuous service, who are eligible 
to participate in a qualified profit-sharing plan of an Affiliated Company 
from which they were transferred, or became, prior to January 1, 1993, and 
remained members of the Retirement Plan of Conoco Inc. (now the Pension and 
Retirement Plan of E. I. du Pont de Nemours and Company (Title 2)); are 
eligible to participate in the Plan.

        An eligible Participant may authorize the Company to make a payroll 
deduction under the Plan ranging from 1% to 19% of monthly compensation.  The 
amount deducted can be deposited into a before-tax or after-tax account or 
some combination thereof; however, no more than 15% may be deposited into a 
before-tax account.  Participants' monthly deductions up to 6% are called 
Basic Deposits.  The Company will contribute an amount equal to 100% of the 
Participant's monthly Basic Deposits.  Subject to certain limitations, certain 
Participants are eligible to make Supplemental Deposits, either as lump sum 
deposits or deposits in the form of monthly deductions in excess of 16%.  Due 
to the discrimination rules of the Internal Revenue Code, only "Non-highly 
Compensated" Participants are currently able to make lump sum Supplemental 
Deposits.

        A Participant with less than five years of participation credit or 
service, who withdraws any matched before-tax or after-tax deposits will 
forfeit a portion of related Company Contributions in accordance with the 
specific Plan provisions.  Company Contributions will be suspended for six 
months if a Participant makes an in-service withdrawal of any earnings in the 
before-tax or after-tax accounts, or Basic Deposits or Company Contributions 
contributed during the last 24 months.  Employee deposits and matching Company 
Contributions will be suspended for up to 12 months if a Participant withdraws 
any before-tax contribution prior to age 59-1/2.  In certain circumstances 
such a withdrawal may also preclude a Participant from making any before-tax 
contributions in the year following the withdrawal.

                                     OF
                                 CONOCO INC.

                 NOTES TO FINANCIAL STATEMENTS - (Continued)
                          (Dollars in Thousands)

        Any vested Participant who separates from service, including one 
who retires, may elect to make a full account withdrawal at any time.  
Required minimum distributions commence in March following the year in 
which a former Participant reaches age 70-1/2.  A Participant who is an 
active employee may elect to defer minimum distributions until he separates 
from service or may elect to commence minimum distribution payments in 
March following the year in which he reaches age 70-1/2.

        Participants may borrow up to one-half of their nonforfeitable 
account balances subject to certain minimum and maximum loan limitations.  
The loans are executed by promissory notes and have a minimum term of 12 
months and a maximum term of 60 months, except for qualified residential 
loans which have a maximum term of 120 months.  The loans bear an interest 
rate equal to the average rate charged by selected major banks to prime 
customers for secured loans.  The loans are repaid over the term in monthly 
installments of principal and interest by payroll deduction.  A Participant 
also has the right to repay the loan in full at any time without penalty.

  INVESTMENT FUNDS

        The following investment funds have been established for the 
investment of Employee Deposits and Company Contributions.  Effective
July 1, 1997, 22 new investment options were added to the Plan to expand 
the investment choices available to Participants.  The new options included 
two index funds, seventeen mutual funds and three asset allocation 
portfolios.  The investment options offered are described below:

Fixed Income Fund
- -----------------
Investments under agreement with one or more financial institutions, 
including insurance companies, banks and other investment entities which 
provide for a predetermined or stable rate of return and are held at 
contract value. 

DuPont Common Stock Fund
- ------------------------
Common Stock of E. I. du Pont de Nemours and Company, Conoco's ultimate 
parent company.

Loan Fund
- ---------
Participant loans--amounts transferred from other funds that are loaned to 
participants.

Merrill Lynch Funds
- -------------------
A total of seven Merrill Lynch investment options are offered, each with its 
own investment objective:

Mutual Funds:

        consistent with prudent risk through global diversification.

                 NOTES TO FINANCIAL STATEMENTS - (Continued)
                            (Dollars in Thousands)

Merrill Lynch Capital Fund - seeks highest total investment return consistent 
        with prudent risk.
Merrill Lynch Basic Value Fund - seeks capital appreciation and income.
Merrill Lynch Growth A - seeks growth of capital and income.

Index Funds:
Merrill Lynch Small Company Stock Index - seeks to track the holdings and 
        total return of the Russell 2000 Index.
Merrill Lynch International Stock Index - seeks to track the holdings and 
        total return of the Morgan Stanley Capital International EAFE (Europe, 
        Australia, and Far East) Index.
Merrill Lynch Equity Index Tier 6 - seeks to track the holdings and total 
        return of the Standard & Poor's 500 Composite Stock Price Index (S&P 
        500 Index).

Effective July 1, 1997, the Merrill Lynch Growth A mutual fund, Merrill Lynch 
Small Company Stock Index and Merrill Lynch International Stock Index were 
added to the Plan as new investment options.

Also on July 1, 1997, the assets of the Merrill Lynch Equity Index were 
transferred into the Merrill Lynch Equity Index Tier 6 Trust, thereby 
eliminating the Equity Index from Merrill Lynch's investment portfolio.  The 
Equity Index Tier 6 Trust is referred to as the Large Company Stock Index in 
Participant communications.  The underlying investment objective, which is to 
track the S&P 500 Index, remains unchanged.

Mutual Funds
- ------------
In addition to the four Merrill Lynch mutual funds listed above, seventeen 
other mutual funds are offered as investment options.  Each of the mutual 
funds has its own investment objective and varying degrees of risk.  The list 
of mutual funds available is:

                            (Dollars in Thousands)

All of these mutual funds, excluding the Fidelity Magellan Fund, were added as 
new investment options effective July 1, 1997.

Asset Allocation Portfolios
- ---------------------------
Four Asset Allocation Portfolios are offered as investment options for 
balancing risk and return:
3-Way Asset Allocation Portfolio - seeks long-term return while controlling 
        risk.
Conservative Asset Allocation Portfolio - seeks lower risk with lower 
        potential return.
Moderate Asset Allocation Portfolio - seeks moderate risk and return.
Aggressive Asset Allocation Portfolio - seeks higher return with higher 
        potential risk.

The Conservative, Moderate and Aggressive Asset Allocation Portfolios were 
added as new investment options effective July 1, 1997.  All three portfolios 
are composed of other investment options which are available in the Plan.  All 
three asset allocation portfolios have as their components the Fixed Income 
Fund, Merrill Lynch Small Company Stock Index Trust and the Merrill Lynch 
Equity Index Tier 6 Trust.  The Moderate and Aggressive portfolios also 
include the Merrill Lynch International Stock Index.  The percentage of 
investment in the Fixed Fund or the other Merrill Lynch options varies 
depending on the risk.

        Participants may allocate their Employee Deposits and Company 
Contributions among all funds at their discretion and may reallocate the 
amounts in their accounts among all funds at their discretion.  Members may 
reallocate the amounts in their accounts among all funds, except the Loan 
Fund, at their discretion.

        Affiliated Company transfers in(out) represent the net movement of 
Participant account balances among the Plan and other defined contribution 
benefit plans of Affiliated Companies.

  ADMINISTRATION
        The designated trustee of all the aforementioned funds is Merrill 
Lynch Trust Company of America (Merrill Lynch).  The administration of the 
Plan is vested in the Employee Benefit Plans Board.  The Board of Directors of 
Conoco Inc. or its delegate may designate three or more persons to serve on 
the Employee Benefit Plans Board, which has the authority to prescribe 
regulations for the administration of the Plan, review all claims for benefits 
under the Plan and enter into agreements with one or more entities, including, 
but not limited to insurance companies, banks, and other investment 
organizations, to provide a stable rate of return for the Fixed Income Fund.

        Brokerage fees, transfer taxes, investment fees and other expenses 
incident to the purchase and sale of securities and investments in the Fixed 
Income Fund, DuPont Common Stock Fund, Asset Allocation Funds, Index Funds, 
and Mutual Funds shall be included in the cost of such securities of 
investments, or deducted from the sales proceeds, as the case may be.  All 
administrative expenses not specified in the preceding sentence, shall be paid

are paid to the Plan, any excess remaining after the reasonable administration 
expenses of the Plan have been paid shall be allocated to the accounts of all 
Participants in the Plan who have an Employee Account balance greater than 
zero on an allocation date designated by the Plan Administrator.  The balance 
of any administrative expenses not paid as described above, shall be paid by 
the Company.

        While the Company has not expressed any intent to terminate the Plan, 
it is free to do so at any time.  In the event the Plan is terminated, all 
Participants become vested and the distribution of all account balances will 
be made based upon the valuation of the Participant's account on the 
termination date.

  RECEIVABLES
        Receivables are comprised of Employee Deposits of $2,905 and $2,666, 
Company Contributions of $1,997 and $2,023, and loan repayments of $1,128 and 
$1,151, which are amounts due as of December 31, 1997 and 1996, respectively.


NOTE 2  --  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

INVESTMENT VALUATION AND INCOME RECOGNITION
        The accompanying financial statements are prepared on the accrual 
basis of accounting.  The Plan's investments are stated at fair value, except 
for the Fixed Income Fund, which is stated at contract value.  The Fixed 
Income Fund guaranteed investment contracts, separate account guaranteed 
investment contracts and synthetic guaranteed investment contracts are fully 
benefit responsive and thus, are stated at cost plus accrued interest, using 
the contracted interest rates applied to the daily account balances.  Mutual 
Funds are valued at quoted market prices which represent the net asset value 
of shares held by the Plan at year-end.  Common/Collective Trust Funds are 
stated at the fair value of all underlying assets as reported by the 
applicable custodian.  Loans to Participants, short-term investments, and cash 
are valued at cost which approximates fair value.  DuPont common stock is 
valued at its quoted market price at year-end.

        The purchase of shares of DuPont common stock may be made in the open 
market or from DuPont if it shall have made treasury or authorized but 
unissued shares available for such purchases, in which event the purchase 
price shall be the closing price of such stock as reported on the New York 
Stock Exchange--Composite Transactions on the last day preceding the date of 
such purchase from DuPont.

        Dividend income is recorded on the ex-dividend date and interest 
income is recorded when earned.  Realized gains and losses on the sale of the 
DuPont Common Stock Fund investment securities are based on average cost of 
the securities sold.  Purchases and sales are recorded on a trade date basis.

  USE OF ESTIMATES

        The preparation of financial statements in conformity with generally 
accepted accounting principles requires the Plan Administrator to make 
estimates and assumptions that affect the reported amounts in the financial 
statements.  Actual results could differ from those estimates.


NOTE 3  --  INVESTMENTS

        The Fixed Income Fund option provided by the Plan is also available to 
Participants in the Investment Plan for Salaried Employees of Consol Inc. (the 
"Consol Plan"), administered by Consol Inc., a corporate joint venture owned 
equally by DuPont and subsidiaries of RWE AG of Germany, and Sentinel 
Transportation Company Thrift Plan (the "Sentinel Plan") administered by 
Sentinel Transportation Company, a wholly-owned subsidiary of DuPont.  
Accordingly, the investments in these funds by Participants in the Plan and 
the Consol and Sentinel Plans have been commingled for investment purposes; 
however, the three Plans' assets are accounted for separately by the trustee.

        The Fixed Income Fund consists of guaranteed investment contracts 
(GICs), separate account GICs (SAGICs), and synthetic guaranteed investment 
contracts (SYNs).

        The following individual contracts represent more than 5% of the net 
assets available for plan benefits as of December 31, 1997 and 1996:

        Metropolitan Life Insurance Co.  - 7.12%, No Maturity Date (SAGIC)
        Prudential Insurance Co.         - 8.55%, 7/01/2001 (SAGIC)
        Prudential Insurance Co.         - 7.08%, 7/01/2001 (SAGIC)

        The ending balances of these contracts are listed below:

                                           Current Value    Current Value
                                             12/31/97         12/31/96

        Metropolitan Life Insurance Co.    $  210,565       $  194,120
        Prudential Insurance Co.              268,581          184,706
        Prudential Insurance Co.                    0          182,121

        The crediting interest rates ranged from 5.74% to 9.96% for the years 
ended December 31, 1997 and 1996.  The fund's blended rate of return for the 
year was 7.62% in 1997 and 7.99% in 1996.

        The crediting rates for most SAGIC and SYN contracts are reset 
annually and are based on the market value of the underlying portfolio of 
assets backing these contracts.  Inputs used to determine the crediting rate 
include each contract's portfolio market value, current yield-to-maturity, 
duration (i.e., the present value of the weighted average life), and market 
value relative to contract value.  All contracts have a guaranteed rate of 0% 
or higher.

        The contract values of investment contracts as of December 31,1997 are 
as follows:

                                                       Contract Value

Separate Account Guaranteed Investment Contracts             479,146
Synthetic Guaranteed Investment Contracts                    962,886
                                                       --------------
                                                       $   1,779,087
                                                       ==============

        The total contract value of $1,779,087 includes direct Participant 
investments of $1,772,699 and investments of $6,388 held by the Conservative, 
Moderate and Aggressive Allocation Portfolios.

        The fair value of synthetic guaranteed investment contracts is 
$987,079.  Included in the fair value of synthetic guaranteed investment 
contracts is $24,193 related to wrapper contracts which guarantee the contract 
value of the synthetic guaranteed investment contracts for participant 
initiated withdrawal events.


NOTE 4  --  REALIZED AND UNREALIZED GAINS AND LOSSES

        Realized and unrealized gains and losses are calculated based upon 
historical cost of assets.  Such gains and losses are computed on a current 
value basis for Form 5500.  The difference may result in a differing 
classification between realized and unrealized but the total gain or loss will 
be unaffected.


NOTE 5  --  INCOME TAX STATUS

        The Internal Revenue Service has determined and informed the Company 
by a letter dated August 7, 1995 that the Plan is qualified and the trust 
established under the Plan is tax-exempt, under the appropriate sections of 
the Code.  The Plan has been amended since receiving the determination letter.  
However, the Plan Administrator and the Plan's tax counsel believe that the 
Plan is currently designed and being operated in compliance with the 
applicable requirements of the Code.

prior to December 31 but not yet paid as of that date.


NOTE 7  --  RELATED PARTY TRANSACTION

        Certain Plan investments are shares of mutual funds managed by the 
Trustee.  Therefore, transactions in these investments qualify as 
party-in-interest transactions which are exempt from the prohibited 
transaction rules.


NOTE 8  --  SUBSEQUENT EVENTS

        Effective January 1, 1998, the maximum allowable monthly contribution 
rate for the before-tax account will increase from 15% to 19%.  Accordingly, 
the total maximum monthly contribution rate (before-tax plus after-tax) will 
increase to 38% subject to certain limitations on total annual contributions.
