REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



The Board of Directors

Deltic Timber Corporation:



We have audited the
accompanying statements of net assets available for benefits of the Thrift Plan of Deltic Timber Corporation as of December 31, 2004 and 2003, and the related statement of changes in net assets available for benefits for the year ended December 31,
2004. These financial statements are the responsibility of the Plans management. Our responsibility is to express an opinion on these financial statements based on our audits.



We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
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. 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 referred to
above present fairly, in all material respects, the net assets available for benefits of the Thrift Plan of Deltic Timber Corporation as of December 31, 2004 and 2003, and the changes in net assets available for benefits for the year ended December
31, 2004, in conformity with U.S. generally accepted accounting principles.



Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule H, Line 4i  Schedule of Assets (Held at End of Year) as of December 31, 2004, is presented
for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labors Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Thrift Plan management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements
and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

THRIFT PLAN OF DELTIC TIMBER CORPORATION

Notes to Financial Statements

December 31, 2004



Note 1 - Description of Plan



General



The Thrift Plan of Deltic Timber Corporation (the Plan) is a
profit sharing, defined contribution plan covering each employee who is scheduled to work, or actually does work, 1,000 or more hours per year. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974
(ERISA). Although it has not expressed any intent to do so, Deltic Timber Corporation (Deltic or the Company) has the right under the Plan to amend or terminate the Plan subject to the provisions of ERISA. For a
more complete description of the Plans provisions, refer to the Plan document.



The Plan is administered by Deltics Pension, Investment, and Employee Benefits Committee (Plan Administrator), whose members are appointed by the Companys Board of Directors. SunTrust Bank
(SunTrust or the Trustee), Nashville N.A. is the Plans trustee.



Contributions



Contributions to the Plan include (a) employee tax-deferred, earnings-reduction contributions, (b) employee after-tax contributions (after-tax contributions were disallowed on January 1, 2003, for new employees, and March 1, 2003, for
current employees), (c) Company matching contributions, (d) employee after-tax supplemental contributions, and (e) rollovers by participants from other qualified plans.



Each year, a participant may contribute, on a combined tax-deferred and/or after-tax basis (after-tax contributions ceased
on March 1, 2003), up to 50 percent (eight percent prior to September 1, 2002) of their annual base earnings. The Company has voluntarily agreed to make annual contributions to the Plan based on each participants contributions and years of
participation. The Company matches 50 percent of employee contributions for the first five years of participation, 75 percent of employee contributions for the second five years of participation, and 100 percent of employee contributions thereafter.
However, Company contributions cannot exceed five percent of an employees annual base pay. Employees after-tax supplemental contributions, which are not matched by the Company, may not exceed 10 percent of their annual base salary. The
Company applies any amounts contributed by the Company that are forfeited by participants in accordance with provisions of the Plan to reduce subsequent contributions. Participants direct the investment of their contributions and company
contributions into various investment options offered by the Plan. The Plan currently offers stock in the Company and eleven mutual funds as investment options for participants.



Throughout various Plan mergers and restatements, the Company has allowed account balances from a former deductible account
to remain in the Plan. However, after December 31, 1986, participants were not allowed to contribute to this account.

Vesting



A participant is vested in Company contributions after (1) completion of three years of service (five years prior to January
1, 2002), (2) retirement on or after age 65, (3) death, (4) total and permanent disability, or (5) discontinuance of the Plan. In the event of Plan termination, participants will become 100 percent vested in Company contributions. A nonvested
participant forfeits Company contributions upon termination of employment.



Withdrawals



A
participant may withdraw employee after-tax contributions or Company contributions, if vested, at a minimum of $250, or any higher multiple of 10 percent of the participants account balance up to 50 percent for a partial withdrawal, or 100
percent for a total withdrawal. If a partial withdrawal is taken, Company contributions will be suspended for six months and another withdrawal cannot be made for 24 months. If a total withdrawal is taken, Company contributions will be suspended for
12 months. Employee contributions may continue without interruption after a partial or total withdrawal.



A participant may withdraw employee tax-deferred contributions or rollovers from other qualified plans under IRS hardship provisions only.
Hardship is an immediate and heavy financial need in one of the following areas: (1) large medical expenses not covered by insurance for the employee or family, (2) purchase of a principal residence (not regular mortgage payments), (3)
preventing foreclosure or eviction from employees principal residence, (4) tuition and related education fees for the next 12 months of post-secondary education for employee or family, or (5) other events as may be determined by the IRS. If a
hardship withdrawal is taken, participation in all accounts is suspended for 6 months. Company contributions are forfeited only upon termination of employment.



An after-tax supplemental withdrawal must be the greater of $250 or 10 percent of the participants account balance and may not be made prior to
12 months from a previous withdrawal.



Withdrawals from the
deductible account (account for participants contributions made prior to January 1, 1987 under a previous plan) are subject to the same withdrawal requirements as after-tax supplemental withdrawals.



Any Company contributions, employee tax-deferred contributions,
contributions to a deductible account, or account earnings withdrawn from the Plan may be subject to a 10 percent penalty tax under the Tax Reform Act of 1986 if the participant is not 59-2 years old, or permanently disabled, or has died.



Upon retirement, disability, or death of a participant, the
participant or his/her spouse, if the designated beneficiary, has the option to receive settlement in a lump sum or installment payments not to exceed 20 years or actuarial life if less than 20 years.

Administrative Expenses



Most administrative expenses are paid by the Company.



Note 2 - Summary of Significant Accounting Policies



Basis of Accounting



The accompanying financial statements of the Plan have been prepared on the
accrual basis of accounting and present the net assets available for benefits and changes in those net assets.



The investments and changes in the net assets available for benefits have been determined by the Trustee and reported to the Plan Administrator based on
quoted market values. Purchases and sales of securities are recorded on a trade-date basis.



The Trustee has been granted discretionary authority concerning the purchase and sale of investments in the trust fund.



Use of Estimates



The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of net assets available for benefits and changes therein. Actual results could differ from those estimates.



Note 3 - Investments



During 2004, the Plans investments, including gains and losses on investments bought and sold, as well as held during the year, appreciated in value
by $1,492,209, as follows:



|                  |  |   |

|Mutual funds      |  | $ | 506,463

The Plan meets the necessary requirements of the Tax Reform Act of 1986 as documented in Section 401(a) of the Internal Revenue Code (IRC), and accordingly, the related Trust is exempt from taxation under the provisions of Section 501(a) of
the Internal Revenue Code. The Internal Revenue Service determined and informed the Company by a letter dated January 28, 2002, that the Plan was designed in accordance with applicable sections of the Internal Revenue Code. By a letter dated
February 24, 2004, the Internal Revenue Service made a favorable determination related to plan amendments enacted in 2003. Until such time as cash or shares are withdrawn from the Plan by a participant or a participants beneficiary, no income
tax is payable by the participant/beneficiary on: contributions made by the Company on the participants behalf, allotments made by the participant pursuant to the Economic Recovery Tax Act of 1981, or any amounts added to the
participants accounts representing his/her proportional share of the investment income of the Trust. The Plan Administrator and tax counsel believe that the Plan is being operated in compliance with the applicable requirements of the IRC.
