Note 1  Interim Financial Statements



The interim financial information included herein is
unaudited; however, such information reflects all adjustments which are, in the opinion of management, necessary for a fair presentation of the Companys financial position, results of operations, and cash flows for the interim periods. All
such adjustments are of a normal, recurring nature. The results of operations for the first nine months of the year are not necessarily indicative of the results of operations which might be expected for the entire year.



The financial statements in Deltics 2004 annual report on Form
10-K/A-1 include a summary of significant accounting policies of the Company and should be read in conjunction with this Form 10-Q. Certain prior period amounts have been reclassified to conform with the 2005 presentation format.



2005 Restatement



As described in the Companys Annual Report on Form 10-K/A-1 for the year ended December 31, 2004, Deltic has
restated its financial statements and other information for the years 2002 through 2004, for the third quarter of 2002, and for each quarter in 2003 and 2004. The restatement related to the correction of an overstatement of the carrying value of the
Companys inventory of third-party purchases of standing timber inventory used to supply its Ola sawmill. The effect of the restatement on Deltics Consolidated Balance Sheet at the end of the reported periods is immaterial and the
restatement had no effect on the Companys net cash flows.



In order to operate its two sawmills economically, the Company relies on purchases of timber (raw material) from third parties to supplement its own timber harvests from Company owned timberlands. Deltic has an active timber procurement
function for each of its sawmills. Sawmill inventory of third-party purchases of standing timber is comprised of timber purchased by the sawmill from third parties that has not yet been harvested and delivered to the mill. When these types of
purchases are made by the Companys procurement function, ownership of the timber located on the designated tract of land transfers to the Company; however, ownership of the land itself does not transfer. The carrying value of this purchased
stumpage inventory is grouped with the Companys wholly-owned timberlands and reported as the line item Timber and Timberlands on Deltics Consolidated Balance Sheet. Over the five years ended December 31, 2004, such purchased
stumpage inventory has represented 2.3 percent to 5.5 percent of the total Timber and Timberlands line-item balance.



At the time that a tract of procurement timber is purchased, an inventory dollar amount, based on the cash payment, and an estimated volume, derived from
estimates made by the procurement foresters, is established. An estimated average cost per ton is obtained by dividing the original cost of the purchased timber on the tract by the original estimated volume of that timber. As the timber is harvested
and brought into the mill, reductions in the purchased timber carrying balance are recorded using the calculated average cost per ton. Once all harvestable timber is removed from a tract, procurement personnel communicate the closing of the tract to
accounting personnel. Upon this notification, a final adjustment is made to mill log cost based on any amount remaining in inventory (an increase in the case of undercut or a decrease in the case of overcut).



In mid-July 2005, the Companys procurement manager for its Ola sawmill
disclosed to senior management that the volume of certain tracts of third-party purchased standing timber inventory for the Ola mill was overstated. The Ola Mill procurement manager largely controlled the information being received by Deltics
accounting personnel. The overstatement arose from his failure to timely report to accounting personnel and

his having concealed from accounting personnel the

Note 2  Impact of Recently
Effective Accounting Pronouncements



In December 2004, the
FASB issued a revision to SFAS 123, Accounting for Stock-Based Compensation. This revision will require the Company to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value
of the award. This revised statement was to be effective as of the beginning of the first interim or annual reporting period that begins after June 15, 2005. In April 2005, the Securities and Exchange Commission announced the adoption of a new
rule that amends the compliance dates for SFAS 123 (Revised) and allows for the implementation of SFAS 123 (Revised) at the beginning of the first fiscal year that begins after June 15, 2005. Accordingly, the Company has elected to adopt the
revised statement effective for its first quarter 2006 financial statements as opposed to the third quarter 2005 financial statements as previously disclosed. The Company remains in the process of evaluating the effect of the adoption of SFAS 123
(Revised) on its consolidated financial statements.



In March
2005, the FASB issued Financial Accounting Standards Board Interpretation (FIN) No. 47, Accounting for Conditional Asset Retirement Obligations. This interpretation clarifies the term conditional asset retirement
obligation as used in SFAS 143, Accounting for Asset Retirement Obligations, and is effective no later than the end of fiscal years ending after December 15, 2005. The Company does not expect the adoption of FIN 47 to have a material
effect on its consolidated financial statements.

Note 2  Impact of Recently Effective
Accounting Pronouncements (cont.)



In May 2005, the FASB
issued SFAS 154, Accounting Changes and Error Corrections. This statement requires all changes in accounting principles to be accounted for by retrospective application to the financial statements for prior periods unless it is impracticable to do
so. SFAS 154 carries forward previously issued guidance with respect to accounting for changes in estimates, changes in the reporting entity and the correction of errors. This statement is effective for accounting changes made in fiscal years
beginning after December 15, 2005. The Company does not expect the adoption of SFAS 154 to have a material effect on its consolidated financial statements.

Note 4  Stock-Based Compensation



Deltic has a stock-based compensation plan for which the
Company applies the recognition and measurement principles of APB 25, Accounting for Stock Issued to Employees, and related interpretations in accounting for those plans. Stock-based employee compensation expense is accrued for the intrinsic value,
if any, of stock options or time-based restricted stock granted over the applicable vesting periods using the straight-line method. Grants of restricted stock subject to predefined performance criteria are accounted for in accordance with
variable-plan accounting. Options granted by the Company have an exercise price equal to the market value of the underlying common stock on the date of grant.



The effect on net income/(loss) and earnings per share if the Company had applied the fair value recognition provisions of the Financial Accounting
Standards Boards Statement of Financial Accounting Standards (SFAS) 123, Accounting for Stock-Based Compensation, consisted of the following:

For the pro forma net
income calculation in the preceding table, the fair value of each option on the date of grant was estimated using the Black-Scholes option-pricing model and the following assumptions for awards in 2005 and 2004, respectively: dividend yields of .81
percent and .90 percent; expected volatilty of 31.54 percent and 30.00 percent; risk-free interest rates of 3.83 percent and 4.10 percent; and expected lives of five years. Using these assumptions, the weighted average grant-date fair value per
share of options granted in 2005 and 2004 was $15.35 and $9.50, respectively.

Fiber, which completed construction and commenced production operations of a medium density fiberboard (MDF) plant near El Dorado, Arkansas, during 1998.



On August 26, 2004, Del-Tin Fiber refinanced its existing long-term debt by entering into a credit agreement,
consisting of a letter of credit and term loan, with multiple lending institutions. The funds provided from this credit agreement were used, together with the existing balance in Del-Tin Fibers debt service reserve and bond sinking fund
accounts, to redeem $60,000,000 of its $89,000,000 industrial revenue bonds. Under the new credit agreement, the lenders, on September 1, 2004, loaned Del-Tin Fiber $30,000,000 which will be repayable over five years in equal quarterly
installments, that began December 31, 2004, and issued on Del-Tin Fibers behalf, a letter of credit in the amount of $29,689,000 to support the remaining industrial revenue bonds originally issued in 1998 by Union County, Arkansas.
Concurrent with this event, on August 26, 2004, Deltic executed a guarantee agreement in connection with the refinancing of the debt of Del-Tin Fiber. Under Deltics guarantee agreement, Deltic unconditionally guarantees the due and
punctual payment of 50 percent ($26,845,000 at September 30, 2005) of Del-Tins obligations under its credit agreement.



The Company has adopted the provisions of FASB Interpretation No. 45, Guarantors Accounting and Disclosure Requirements for Guarantees,
Including Indirect Guarantees of Indebtedness of Others, an interpretation of FASB Statements No. 5, 57 and 107 and a rescission of FASB Interpretation No. 34 (FIN 45). In accordance with FIN 45, Deltic estimated the fair value
of its guarantee of Del-Tin Fibers credit agreement to be $3,450,000 and included this non-cash amount in the Companys Consolidated Balance Sheet as a long-term liability with an offsetting increase in the Companys investment in
Del-Tin Fiber. Deltic is reducing this liability systematically over the life of the credit agreement, as the Company is released from risk under the guarantee. Simultaneously, the offsetting amount which represents the difference between the
Companys recorded investment in Del-Tin Fiber and its underlying equity in the net assets of the joint venture is being amortized over the same period as the guarantee. The amortization of the guarantee and the basis difference are netted for
purposes of financial reporting and result in no net income statement effect. At September 30, 2005, Deltics remaining liability regarding the guarantee was $2,760,000.

DELTIC TIMBER CORPORATION

AND SUBSIDIARIES

Notes to Consolidated Financial Statements

September 30, 2005

(Unaudited, except for
December 31, 2004)



Note 9  Employee and Retiree Benefit Plans
(cont.)



The Company made contributions to its qualified
retirement plan of $900,000 during the first nine months of 2005. Deltic expects to contribute an additional $225,000 to the qualified retirement plan during the fourth quarter of 2005.



During the third quarter of 2004, Deltic applied the effect of the Medicare Prescription Drug, Improvement and Modernization
Act of 2003 to its obligation under the Companys other postretirement benefits plan. The prescription drug benefits offered by the Companys plan were determined to be at least actuarially equivalent to those provided with the Act, which
qualified the plan to receive federal subsidy payments under Medicare Part D. The amount of the reduction in the Companys obligation under the plan relating to benefits received from the Act attributable to past service was $590,000. The
reduction, as a result of the application of the federal subsidy, in the postretirement benefit expense for the quarter and nine months ended September 30, 2004 was $44,000.



Note 10  Supplemental Cash Flow Disclosures



Income taxes paid, net of refunds, were $7,983,000 and $1,933,000 in the 2005 and 2004 periods, respectively. Interest paid,
net of amounts capitalized, was $2,940,000 and $3,246,000 in the first nine months of 2005 and 2004, respectively.

Note 12  Income Taxes



Income tax expense was $8,000 for the third quarter of 2005 and $2,326,000
for the third quarter of 2004, resulting in effective income tax rates of zero and 39 percent for the 2005 and 2004 periods respectively. The reduction in income tax expense during the third quarter of 2005 was due to an income tax benefit created
by the impact of the reversal of a $1,686,000 estimated valuation allowance related to accumulated state net operating loss carryforwards. Based on current projections of increased future taxable income, it is now more likely than not that the
future benefits of these state net operating losses will be utilized in their entirety. The non-cash income tax benefit resulting from the reversal of this estimated valuation allowance amounted to $1,096,000, $.09 per share, for the third quarter
of 2005. Before recording the reduction in the valuation allowance, the Companys effective income tax rate for the third quarter of 2005 was 34 percent. The decrease in this effective tax rate when compared to the third quarter of 2004, was
due to lower effective rates for state income taxes in the third quarter of 2005.



Income tax expense was $4,836,000 for the first nine months of 2005 and $5,036,000 for the first nine months of 2004, resulting in effective income tax rates of 28 percent and 39 percent for the 2005 and 2004 periods
respectively. The reduction in income tax expense during the first nine months of 2005 was due to an income tax benefit created by the impact of the reversal of a $2,612,000 estimated valuation allowance related to accumulated state net operating
loss carryforwards. The non-cash income tax benefit resulting from the reversal of this estimated valuation allowances amounted to $1,697,000, $.14 per share, for the first nine months of 2005. Before recording this reduction in the valuation
allowance, the Companys effective income tax rate for the first nine months of 2005 was 38 percent.



Note 13  Credit Facilities



On September 9, 2005, the Company entered into an agreement with SunTrust Bank and other banks which provides an unsecured, committed revolving credit facility totaling $260,000,000, which includes a $50 million
letter of credit feature. The agreement, which will expire September 9, 2010, replaces the current facility that was scheduled to expire July 15, 2007. As of September 30, 2005, $247,500,000 was available in excess of all borrowings
outstanding under or supported by the facility. Borrowings under the agreement bear interest at a base rate or an adjusted Eurodollar rate plus an applicable margin, depending upon the type of loan the Company executes. The applicable margin
component of the interest rate varies with the type of loan and the Companys total debt to capital ratio. Borrowings outstanding at September 30, 2005, amounted to $12,500,000. Fees associated with this revolving credit facility include a
commitment fee of .15 to .375 percent per annum on the unused portion of the committed amount. The agreement contains restrictive covenants, including limitations on the incurrence of debt and requirements to maintain certain financial ratios. The
Company incurred cost of $657,500 related to the securing of this facility, which was deferred and is being amortized as additional interest expense over the term of the agreement.

Note 14  Contingencies



During 2004, the Company disclosed its plans for a 1,170-acre, 187 lot,
upscale residential development, The Ridges at Nowlin Creek, on a portion of Deltics large land holdings located west of Little Rock, Arkansas. A portion of the development is located within the watershed of Lake Maumelle, a principal source
of drinking water for the City of Little Rock. On September 19, 2005, the local water utility filed a petition in the Circuit Court of Pulaski County, Arkansas, to condemn that portion of the development within the lakes watershed, and
deposited $3,830,000 as its estimate of just compensation for the land taken. The condemned property includes 99 lots, parts of an additional 20 lots, and proposed access to seven lots.



Upon application by Deltic, on October 11, 2005, the funds were transferred into the Companys bank account. Under
Arkansas law, Deltic has the right, and has initiated proceedings to have a jury determine the true amount of just compensation for the lands, as well as other damages. The court hearing regarding this matter will likely be scheduled to begin in
2006. Under Arkansas statutes, as interpreted by its courts, condemnation proceedings of this nature by a municipal utility, do not vest fee simple title to the land, until the utility pays the final judgement of just compensation in the case.
Should the utility decide not to pay the final judgement, possession and full title is returned to Deltic and the utility is liable for damages during the period Deltic is dispossessed of its property and legal fees.



Due to this contingent component of the transaction, no gain will be
recorded in the Companys Consolidated Statement of Income until fee simple title of the property is transferred from the Company. As a result of the October 11 deposit of the $3,830,000 into Deltics bank account, a long-term
deferred liability equal to these cash proceeds received will be included in the Companys Consolidated Balance Sheet beginning in the fourth quarter of 2005.

2005 Restatement



As discussed in the 2005 Restatement section on page 2 and further described in Note 1 to the consolidated financial statements, the Company has restated
its financial statements and other information for the years 2002 through 2004, for the third quarter of 2002, and for each quarter in 2003 and 2004.



Executive Overview



The Company recorded net income of $3.3 million for the third quarter of 2005 compared to $3.7 million for the same period of 2004. For the seventh
consecutive quarter, all three operating segments of the Company  Woodlands, Mills, and Real Estate  contributed earnings. Deltics Woodlands segment continued its role as the established core operation of the Company during the
third quarter, providing $6 million in operating income. Deltics Mills segment maintained its profitability during the third quarter despite facing lower pricing levels and increased raw material costs. The Real Estate segment closed a lower
level of residential lot sales during the third quarter of 2005 compared to the same period last year, primarily due to this years lot offering schedule and the inherent time lag between the offering of a neighborhood and the actual closing of
sales from that offering. Our 50 percent-owned joint venture, Del-Tin Fiber, also recorded a slight profit in the third quarter as the facility continues its recovery from the fire-related temporary production curtailment experienced during the
first quarter of 2005, and was impacted during the period by lower sales realizations and higher petroleum-based resin material costs.



With the exception of its diversification in real estate development, Deltic is primarily a wood products producer operating in a commodity-based business
environment. This environment is affected by a number of factors, including general economic conditions, interest rates, imports, foreign exchange rates, housing starts, residential repair and remodeling, commercial construction, industry capacity
and production levels, the availability and prices of raw material and weather conditions. Given its relative size and the nature of most commodity markets, the Company has little or no control over pricing levels for its wood products. Therefore,
the Company continually seeks to make gains in production efficiencies and control costs and expenses from its manufacturing process. Sales of real estate are affected by general economic conditions and interest rates, specifically as such factors
are manifested in the Companys operating area of central Arkansas.



For the third quarter of 2005, pine sawtimber harvest levels increased 9,097 tons, to 159,512 tons, when compared to the third quarter of 2004. Pine sawtimber harvest levels for the nine months ending
September 30, 2005, increased nine percent to 494,554 tons when compared to the same period of last year; however, the Companys plan to keep 2005s total pine sawtimber harvest volume comparable to the level in 2004 remains in place,
which will result in a smaller harvest in the fourth quarter when compared to last years period. During the third quarter, area sawmills largely recovered from their over-depletion of log inventories, caused by greater-than-normal levels of
rainfall earlier in the year. However, high lumber production levels continued the strong demand, and corresponding price, for pine sawtimber logs within the Companys operating region, and Deltic increased harvesting activities during the
period to take advantage of these prices. Ultimately, the Companys long-term ability to sell pine sawtimber at acceptable prices in the future will be dependent upon the size and strength of markets for manufactured lumber and other wood
products. Activities to sell timberland identified as having a higher and better use or as being non-strategic remains. However, such sales will only be considered to the extent that the returns on these transactions meet the previously disclosed
increased expectations of the Company. There were no timberland sales during the third quarter of 2005. Timberland designated as higher and better use consists of tracts with market values that exceed the lands worth as a timber growing
platform.

Non-strategic timberland consist primarily of tracts too small to allow efficient timber management, those geographically
isolated from other Company fee lands, and acreage otherwise not deemed strategic to Deltics operations or growth.



Deltic continues its efforts to increase production efficiencies and reduce manufacturing costs within its sawmill operations; however, raw material log
costs remained at high levels throughout the third quarter of 2005 and was a significant factor in the segments reduced operating income when compared to the third quarter of 2004. As with any commodity market, the Company expects the
historical volatility of lumber prices to continue in the future. Except for a temporary spike of about two weeks in duration immediately following Hurricane Katrina, the U.S. softwood lumber industry saw composite prices decrease during the third
quarter. While there was a modest decline in housing starts in August, overall analysts projections of total 2005 starts are still at levels in excess of 2004s record setting volumes. The Company anticipates that a moderate percentage of
logs supplied to both of its sawmills will come from strategically located Company fee timberlands.



During the third quarter of 2005, Deltics Real Estate segment closed a lower number of residential lot sales, primarily due to this years lot
offering schedule and the inherent time lag between the offering of a neighborhood and the actual closing of sales from that offering. The segment closed the sale of 31 residential lots during the third quarter of 2005, at a 28 percent higher
average sales price per lot when compared to the same quarter of last year. The reported average sales price for residential lots for a specific period is largely dependent upon the mix of lot sales closed in that period. Deltics lot
development plans provide for a mix of lot offerings that represent most real estate market segments for planned communities. Sales activity levels for the Companys real estate developments are affected by economic conditions that influence
the level of housing starts in the central Arkansas region, including general economic conditions and interest rates. New residential construction in the west Little Rock speculative home market may be showing signs of the impact of higher interest
rates, energy cost, and building material cost. During the Companys recent third quarter neighborhood offering within the entry-level, residential product class in Chenal Valley, Deltic experienced a decline in commitments from area builders.
The Company believes the recent rise in building cost is temporary and our current plans are to develop approximately 80 additional lots within Chenal Valley and 55 lots within our Red Oak Ridge development located in Hot Springs, Arkansas by the
end of 2005. Deltics other active development, Chenal Downs, is fully developed with 21 uncommitted residential lots as of September 30, 2005. Future annual development activity will be dependent upon the demand for the Companys
residential lots.



During 2004, the Company disclosed its plans
for a 1,170-acre, 187 lot, upscale residential development, The Ridges at Nowlin Creek, on a portion of its large land holdings located west of Chenal Valley. A portion of the development is located within the watershed of Lake Maumelle, a principal
source of drinking water for Little Rock. Due to this environmentally sensitive locale, the Companys plans included the most modern, and proven, best management practices to create a low-impact development in order to protect water quality in
the lake. Even though the local water utility has commissioned the preparation of a new watershed management plan which supposedly will reflect current scientific principles that would likely be compatible with the Companys low-impact
development plans, on September 19, 2005, the utility filed its petition in the Circuit Court of Pulaski County, Arkansas, to condemn that portion of the development within the lakes watershed, and deposited $3.8 million as its estimate
of just compensation for the land taken. The condemned property includes all of 99 lots, parts of an additional 20 lots, and proposed access to seven lots. Upon application by Deltic, on October 11, 2005, the funds were transferred into the
Companys bank account. Under Arkansas law, Deltic has the right, and has recently initiated proceedings, to have a jury determine the true amount of just compensation for the lands, as well as other damages. The court hearing regarding this
matter will likely be scheduled to begin in 2006. Under Arkansas statutes, as interpreted by its courts, condemnation proceedings of this nature by a municipal utility do not vest fee simple title to the land until the utility pays the final
judgement of just compensation determined in the case. Should the utility decide not to pay the final judgement, possession and full title is returned to Deltic and the utility is liable for damages during the period Deltic is dispossessed of its
property, in addition to legal costs incurred by the landowner. The commencement of this action will cause activities at the Ridges at Nowlin Creek development to be

postponed pending the outcome of the action. Should the utility determine to pay the final judgement, the Company will
need to further assess the viability of proceeding with development of lots in the developments remaining acreage. (For further discussion, refer to Note 14 to the consolidated financial statements.)



Commercial real estate sales activity is by nature less predictable than
residential activity. No commercial sales occurred in the third quarter of 2005 or 2004. With the number of residents in Chenal Valley, and other west Little Rock areas, growing steadily and momentum created from previous sales of commercial acreage
in the development, interest in the Companys remaining commercial acreage remains strong. On April 6, 2004, RED Development LLC announced plans for The Promenade at Chenal, a 48-acre, open-air, lifestyle shopping center. The
sales contract regarding this site was initially scheduled to close before the end of 2004. However, as is the inherent unpredictable nature of commercial real estate sales, the contract has been extended and is now scheduled to close during the
fourth quarter of 2005. The Company continues to assist Red Development in its study of the site and currently has no reason to anticipate that closing of this sale will not occur in 2005. However, some extensions of similar contracts in the past
have been followed by the termination of the commercial sale. No commercial acreage is included in the Chenal Downs or the Ridges at Nowlin Creek developments. Red Oak Ridge is planned to include approximately 80 acres of commercial property. The
Company plans to begin to develop and offer commercial sites as this developments population density increases.



Operating results for Del-Tin Fiber are affected by the overall MDF market and the plants operating performance, and both experienced significant
improvements during 2004. However, the facilitys 2005 operations were hindered by a temporary production curtailment caused by a fire sustained at the plant during the first quarter. The presence of the unscheduled downtime caused by the fire
has forced the facility to reduce its 2005 projected total production volume. However, the efficiencies and improved key manufacturing production metrics established during 2004, which are still present at the plant, should allow the joint venture
to produce close to its design capacity of 150 million square feet in 2005. The plant returned to profitability during the second quarter of 2005, and recorded a slight profit in the third quarter of 2005. The MDF market has softened during the
last half of the year, and high petroleum-based resin material costs have impacted Del-Tin Fibers financial results. Deltics focus remains on the continuation of the facilitys recent operating and financial improvements throughout
the remainder of 2005.

Consolidated



The $.4 million decrease in net income was the result of
decreased operating income from Deltics Mills and Real Estate segments, partially offset by a decrease in income tax expense.



Operating income decreased $2.2 million. The Woodlands segment increased $1 million due primarily to an increased pine sawtimber harvest level and an
increased average per-ton pine sawtimber price. Deltics Mills segment operations decreased $1.3 million due to an increase in raw material costs. Real Estate operating income decreased $2.7 million due to a reduction in residential lot sales
and to the third quarter of 2004 benefiting from the sale of a 94-arce tract of undeveloped real estate property. Corporate operating expense decreased $.7 million primarily due to lower professional fees.

Total net sales
increased $1.8 million, which was driven predominately by increases in sales volume for all of the Companys timber species at higher average sales prices for pine sawtimber, pine pulpwood, and hardwood pulpwood. The remainder of the increase
in total net sales was a $.3 million increase in freight revenue. Operating income increased $1 million due to the increase in net sales, partially offset by increases in cull timber removal expense, freight expense, and cost of fee timber
harvested. (Cull timber removal is a seasonal expense normally incurred each year during the third and fourth quarters.)

Total net sales increased $.1 million due to an increase in the sales of residual by-products which was
offset by decreased lumber sales. The decrease in operating income of $1.3 million was due primarily to increased raw material log costs.

Total net sales
decreased $6.8 million, or 61 percent, due to the reduction in residential lot closings and the sale of a 94-acre tract of undeveloped real estate property in the third quarter of 2004, with no undeveloped acreage sales in the 2005 period. The
decrease in the Real Estate segments operating income was due primarily to the same factors impacting net sales.



Corporate



Operating expense for Corporate functions decreased $.7 million due primarily to decreased professional fees relating to the Companys compliance
with Section 404 of the Sarbanes Oxley Act of 2002.



Eliminations



Intersegment sales of timber
from Deltics Woodlands to the Mills segment increased $1.6 million to $6.8 million. The increase was due to increases in both the volume and price of logs coming into Deltics sawmills from the Companys fee timberlands. Logs
supplied by the Woodlands segment to the Companys sawmills are transferred at prices that approximate market.



Equity in Del-Tin Fiber



For the third quarter of 2005, equity in Del-Tin Fiber decreased $.4 million. The decline in income was due primary to increased raw material costs,
principally resin. The joint venture experienced a market-driven decline in per-unit sales price during the third quarter of 2005; however, this decline was essentially offset by increased sales volume when compared to the prior-year period.

Income Taxes



The Company realized virtually no income tax expense
during the third quarter of 2005, while the effective income tax rate was 39 percent in the 2004 period. The low amount of income tax expense during the third quarter of 2005 was due to the impact of an income tax benefit created by a reversal of
the estimated valuation allowance related to accumulated state net operating loss carryforwards. Based on current projections of increased future taxable income, it is now more likely than not that the future benefits of these state net operating
losses will be utilized in their entirety. Before recording the reduction in the valuation allowance, the Companys effective income tax rate for the third quarter of 2005 was 34 percent. The decrease in this effective tax rate when compared to
the prior year period was due to lower effective rates for state income taxes in the 2005 period.

Consolidated



While each of the Companys three operating segments
experienced improved financial results during the first nine months of 2005 when compared to the 2004 period, the $4.4 million increase in net income was principally the result of improved financial results for the Companys Woodlands segment.



Operating income increased $4.4 million. The Woodlands segment
increased $4.5 million due primarily to an increased pine sawtimber harvest level and an increased average per-ton pine sawtimber price. Deltics Mills segment operations improved $.2 million due mainly to a 16 percent increase in finished
lumber sales volume at a two percent higher average lumber sales price, offset by increased raw material log costs. Real Estate operating income increased $.5 million despite decreases in sales volumes for residential lots, commercial acreage, and
undeveloped real estate acreage, due primarily to increased profit margins on residential lot sales resulting from a 27 percent increase in average price per lot sold. Corporate operating expense remained relatively flat, decreasing $.1 million.

##### Table of Contents

Total net sales increased $5.3 million, which was driven almost entirely by the increase in sales volume
of pine sawtimber at a higher average sales price. Revenues from the sale of other timber species also increased during the first nine months of 2005. The segment also reported a $.3 million increase in hunting lease revenue. However, these
increases were partially offset by a reduction in timberland sales. Operating income increased $4.5 million primarily as a result of the 24 percent increase in sales of pine sawtimber combined with only a nine percent increase in the cost of fee
timber harvested due mainly to harvest mix.



Mills

Total net sales
increased $16 million, or 21 percent, due to the increase in finished lumber sales volume combined with a slightly higher average sales price. Revenue from sales of residual by-products increased due mainly to increased lumber production volumes.
The improvement in operating results of $.2 million was due primarily to the increase in net sales, substantially offset by increased raw material log costs.

##### Table of Contents

Total net sales decreased $.7 million primarily due to the reduction in sales of undeveloped real estate
property. Net sales from residential lot closings increased when compared to the first nine months of 2004, despite a decrease in residential lot sales volume, due to a 27 percent increase in average sales price per lot. The increase in the Real
Estate segments operating income, despite the decrease in total net sales, was due primarily to the mix of residential lots sold and improved margins within the segment.



Corporate



The decrease in operating expense for Corporate functions of $.1 million was due to decreased general and administrative expenses.



Eliminations



Intersegment sales of timber from Deltics Woodlands to the Mills
segment increased $3.5 million to $17.4 million. The increase was due to increases in both the volume and price of logs coming into Deltics sawmills from Company fee timberlands. Logs supplied by the Woodlands segment to the Companys
sawmills are transferred at prices that approximate market.



Equity in Del-Tin Fiber



For the first nine
months of 2005 equity in Del-Tin Fiber was $.1 million, a decrease of $.4 million when compared to the prior-year period. During the first quarter of 2005, the facilitys operations were hindered by a temporary production curtailment caused by
a fire sustained at the plant. The effect of the first quarter curtailment was decreases in both finished production and sales volumes for the plant.



Additional selected financial and statistical data for Del-Tin Fiber is shown in the following table.



|                                |  |                                |       |      |

Average sales price
increased three percent due to the improvements in the MDF market and to continued changes in product mix to include a greater percentage of thin board and an increase in premium-grade production. Manufacturing cost per MSF sold was up six percent
due to decreased production volume and increased raw material costs, principally resin.



Income Taxes



The
effective income tax rate was 28 percent and 39 percent in the 2005 and 2004 periods, respectively. The decrease in the effective income tax rate for the first nine months of 2005 was due to the impact of an income tax benefit created by a reversal
of the estimated valuation allowance related to accumulated state net operating loss carryforwards. Based on current projections of increased future taxable income, it is now more likely than not that the future benefits of these state net operating
losses will be utilized in their entirety. Before recording the reduction in the valuation allowance, the Companys effective income tax rate for the first nine months of 2005 was 38 percent.

Liquidity and Capital Resources



Cash Flows and Capital Expenditures



Net cash provided by operating activities totaled $29.6 million for the first nine months of 2005 compared to $33.6 million
for the same period in 2004. Changes in operating working capital, other than cash and cash equivalents, provided cash of $2 million in the 2005 period and $4.5 million in 2004. The Companys accompanying Consolidated Statements of Cash Flows
identify other differences between net income/(loss) and cash provided by operating activities for each reporting period.



Capital expenditures required cash of $25.2 million in the current-year period and $16.5 million a year ago. Capital expenditures by segment consisted of
the following:

The net change in purchased stumpage inventory to be utilized in the Companys sawmill operations provided cash of $2
million in 2005 and $3 million in 2004. The Company made advances to Del-Tin Fiber of $4.2 million and received cash of $2.4 million for net advances of $1.8 million during the current period, which increased $1.1 million from the corresponding
period of 2004. The increase in net advances to Del-Tin Fiber was due primarily to the costs to repair fire damage in the plant during the first quarter of 2005 and to the corresponding production curtailment at the facility. During 2004, $4.4
million of proceeds from sales of timberland that were previously held by a trustee were used to acquire timberland designated as replacement property for income tax purposes, as required for tax-deferred exchanges. In 2005, Deltic
borrowed $11.5 million and made repayments of debt of $14.7 million. During 2004, Deltic made repayments of previous borrowings under its revolving credit facility of $23 million. Deltic paid dividends on common stock of $2.5 million during the
current period, slightly higher than the $2.3 million dividend payments in 2004. This increase in dividend payments reflects the Companys 20 percent increase in its quarterly dividend payment announced and implemented during the third quarter
of 2005. In 2005, proceeds from stock option exercises amounted to $1.4 million, a decrease of $3.1 million when compared to 2004. For the 2005 period, cash outflows for other-net financing activities consisted primarily of deferred debt issuance
costs capitalized during the third quarter.



Financial
Condition



Working capital totaled $6.2 million at
September 30, 2005, and $6.5 million at December 31, 2004. Deltics working capital ratio at September 30, 2005, was 1.44 to 1, compared to 1.73 to 1 at the end of 2004. Cash and cash equivalents at the end of the third quarter
of 2005 were $1.7 million compared to $.9 million at the end of 2004. During the first nine months of 2005, total indebtedness of the Company decreased $3.2 million to $82.5 million. Deltics long-term debt to stockholders equity ratio
was .421 to 1 at September 30, 2005, compared to .466 to 1 at year-end 2004.

##### Table of Contents

Liquidity



The primary sources of the Companys liquidity are internally generated funds, access to outside financing, and working
capital. The Companys current strategy for growth continues to emphasize its timberland acquisition program, in addition to expanding lumber production as market conditions allow and developing real estate at Chenal Valley, Red Oak Ridge and
the currently suspended Ridges at Nowlin Creek.



To facilitate
these growth plans, on September 9, 2005, the Company completed negotiation with SunTrust Bank and other banks for an unsecured and committed revolving credit facility totaling $260 million. The facility also contains a $50 million letter of
credit feature. The agreement, which will expire on September 9, 2010, replaces the current facility that was scheduled to expire July 15, 2007. As of September 30, 2005, $247.5 million was available in excess of all borrowings
outstanding under or supported by the facility. The agreement contains restrictive covenants, including limitations on the incurrence of debt and requirements to maintain certain financial ratios.



In December 2000, the Companys Board of Directors authorized a stock
repurchase program of up to $10 million of Deltic common stock. As of September 30, 2005, the Company had expended $2.1 million under this program, with the purchase of 96,206 shares at an average cost of $22.34 per share; no shares have been
purchased in 2005 under this program. In its two previously completed repurchase programs, Deltic purchased 479,601 shares at an average cost of $20.89 and 419,542 shares at a $24.68 per share average cost, respectively.



Off-Balance Sheet Arrangements, Contractual Obligations, and Commitments



On August 26, 2004, Del-Tin Fiber refinanced its
existing long-term debt by entering into a credit agreement consisting of a letter of credit and term loan with multiple lending institutions. The funds provided from this credit agreement were used, together with the existing balance in Del-Tin
Fibers debt service reserve and bond sinking fund accounts, to redeem $60 million of its $89 million industrial revenue bonds. Under the new credit agreement, the lenders, on September 1, 2004, loaned Del-Tin Fiber $30 million which will
be repayable over five years in equal quarterly installments, that began December 31, 2004, and issued on Del-Tin Fibers behalf, a letter of credit in the amount of $29.7 million to support the remaining industrial revenue bonds
originally issued in 1998 by Union County, Arkansas. Concurrent with this event, on August 26, 2004, Deltic executed a guarantee agreement in connection with the refinancing of the debt of Del-Tin Fiber. Under Deltics guarantee agreement,
Deltic unconditionally guarantees the due and punctual payment of 50 percent ($26.8 million at September 30, 2005) of Del-Tins obligations under its credit agreement.



The Company has adopted the provisions of FASB Interpretation (FIN) No. 45, Guarantors Accounting and
Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an interpretation of FASB Statements No. 5, 57 and 107 and a rescission of FASB Interpretation No. 34. In accordance with FIN 45, Deltic
initially estimated the fair value of its guarantee of Del-Tin Fibers credit agreement to be $3.5 million and included this non-cash amount in the Companys Consolidated Balance Sheet as a long-term liability with an offsetting increase
in the Companys investment in Del-Tin Fiber. Deltic is reducing this liability systematically over the life of the credit agreement, as the Company is released from risk under the guarantee. At September 30, 2005, Deltics remaining
liability regarding the guarantee was $2.8 million.



The
Company has both funded and unfunded noncontributory defined benefit retirement plans that cover the majority of its employees. The plans provide defined benefits based on years of service and final average salary. Deltic also has other
postretirement benefit plans covering substantially all of its employees. The health care plan is contributory with participants contributions adjusted as needed; the life insurance plan is noncontributory. (For information about material
assumptions underlying the accounting for these plans and other components of the plans, refer to Note 13 to the consolidated financial statements included in the Companys 2004 annual report on Form 10-K/A-1.)

Outlook



Deltics
management believes that cash provided from its operations and the remaining amount available under its credit facility will be sufficient to meet its expected cash needs and planned expenditures, including those of the Companys continued
timberland acquisition and stock repurchase programs, additional advances to Del-Tin Fiber, and capital expenditures, for the foreseeable future.



Critical Accounting Policies and Estimates



Critical accounting policies are defined as those that are reflective of significant judgements and uncertainties and potentially result in materially
different results under different assumptions and conditions. The Company has prepared its consolidated financial statements in conformity with accounting principles generally accepted in the United States, which require management to make estimates
and assumptions that affect the reported amounts in these financial statements and accompanying notes. Actual results could differ from those estimates under different assumptions or conditions. The Company has disclosed its critical accounting
policies in its 2004 annual report on Form 10-K/A-1, and this disclosure should be read in conjunction with this Form 10-Q. There have been no changes in these identified critical policies, nor have there been any initially adopted accounting
policies having a material impact on reported financial results.

Impact of Recently Effective Accounting Pronouncements



(For information regarding the impact of recently effective accounting
pronouncements, refer to Note 2 to the consolidated financial statements.)



Outlook



Pine sawtimber harvest levels are
expected to be 65,000 to 80,000 tons in the fourth quarter of 2005 and 560,000 to 575,000 tons for the year. Significant sales of timberland identified to have a higher and better use or to be non-strategic are not anticipated, but may reach 100
acres for the year. Finished lumber production and sales volume will continue to be subject to market conditions, and is estimated at 75 to 85 million board feet for the fourth quarter and 275 to 285 million board feet for the year.
Residential lot sales are projected to be 105 to 125 lots and 260 to 280 lots for the fourth quarter and the year, respectively.

Item 3. Quantitative and Qualitative Disclosures About Market Risk



The Companys market risk has not changed significantly from that set forth under the caption Quantitative and Qualitative Disclosures About
Market Risk, in Item 7A of Part II of its 2004 annual report on Form 10-K/A-1. Those disclosures should be read in conjunction with this Form 10-Q.



Item 4. Controls and Procedures



Deltic Timber Corporation (Deltic or the Company) has established disclosure controls and procedures to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known
to the officers who certify the Companys financial reports and to other members of senior management and the Board of Directors.



Based on their evaluation as of September 30, 2005, the Chief Executive Officer and Chief Financial Officer of the Company have concluded that the
Companys disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934) are effective to ensure that the information required to be disclosed by the Company in the reports that it
files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.



Changes in Internal Control Over Financial Reporting



Deltics management, with the Chief Executive Officer and Chief Financial Officer, have evaluated any changes in the
Companys internal control over financial reporting that occurred during the Companys most recent fiscal quarter, and have concluded that there were changes to Deltics internal control over financial reporting that materially
affected Deltics internal control over financial reporting.



During the fiscal quarter ending June 30, 2005, the following material weaknesses in internal control over financial reporting related to accounting for third-party purchased stumpage timber inventory were discovered:



| |  |  | a lack of segregation of duties related to the timber procurement function, in that the procurement manager calculated the estimated volumes on purchased tracts of third-party
standing timber, approved purchases of tracts of third-party standing timber up to the level of his approval authority, monitored logging activity on all procured tracts, reported such logging activity to accounting personnel, maintained the records
of expiration dates for logging rights for all procured tracts, obtained extensions to original expiration dates for all procured tracts, and determined the timing of reporting to accounting personnel that logging activities on procured tracts had
been completed;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a lack of frequent and comprehensive review of status updates for each respective tract of third- party standing timber;
| | - |  | ------------------------------------------------------------------------------------------------------------------------



| |  |  | a lack of established procedures requiring adjustment in the carrying value of procured tracts when there are no current reports of logging activity reported to accounting
personnel, unless an affirmative justification is timely presented and approved; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a lack of training and education designed to ensure that all relevant personnel involved in third-party purchased standing timber transactions understand and apply the proper
accounting procedures.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

During the fiscal quarter ending September 30, 2005, the Companys management implemented and
thoroughly tested new policies and procedures that were intended to fully remediate the material weaknesses in internal control over financial reporting with respect to accounting for third-party purchased standing timber inventory. These remedial
actions included:



| |  |  | substantially increased the segregation of duties related to the acquisition of and accounting for third-party purchased standing timber inventory, including a reduction in the
expenditure authority levels of mill procurement personnel to increase involvement of management in acquisitions;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | instituted new requirements in connection with third-party purchased standing timber inventory for the creation and wider distribution of records and documentation beginning with
the original estimation process prior to acquisition of tracts of third-party purchased standing timber inventory and continuing through the final harvest and volume reconciliation for each tract;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | imposed more frequent and comprehensive status updates for each respective tract of third- party purchased standing timber inventory with active participation by both procurement
and accounting personnel;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | established default procedures that require adjustments in the carrying value of respective tracts where no current reports of logging activity are being made by procurement
personnel to accounting personnel, unless an affirmative justification is timely presented and approved;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | provided for additional training and education designed to ensure that all relevant personnel involved in the transactions understand and apply the proper accounting for third-party
purchased standing timber inventory; and
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | extended the Companys sub-certification requirements relating to information supplied which may form a part of the Companys accounting books and records to include all
procurement managers and supervisors.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The
Company did not identify any other material weaknesses in its internal controls over financial reporting during the fiscal quarter ending September 30, 2005. There were no other changes in the Companys internal control over financial
reporting during the quarter ended September 30, 2005, that materially affected, or is reasonably likely to materially affect, the Companys internal control over financial reporting.
