The report of the Secretary of the Treasury affords much information respecting the revenue and commerce of the country. His views upon the currency and with reference to a proper adjustment of our revenue system, internal as well as impost, are commended to the careful consideration of Congress. In my last annual message I expressed my general views upon these subjects. I need now only call attention to the necessity of carrying into every department of the Government a system of rigid accountability, thorough retrenchment, and wise economy. With no exceptional nor unusual expenditures, the oppressive burdens of taxation can be lessened by such a modification of our revenue laws as will be consistent with the public faith and the legitimate and necessary wants of the Government.

The report presents a much more satisfactory condition of our finances than one year ago the most sanguine could have anticipated. During the fiscal year ending the 30th June, 1865 (the last year of the war), the public debt was increased $941,902,537, and on the 31st of October, 1865, it amounted to $2,740,854,750. On the 31st day of October, 1866, it had been reduced to $2,551,310,006, the diminution during a period of fourteen months, commencing September 1, 1865, and ending October 31, 1866, having been $206,379,565. In the last annual report on the state of the finances it was estimated that during the three quarters of the fiscal year ending the 30th of June last the debt would be increased $112,194,947. During that period, however, it was reduced $31,196,387, the receipts of the year having been $89,905,905 more and the expenditures $200,529,235 less than the estimates. Nothing could more clearly indicate than these statements the extent and availability of the national resources and the rapidity and safety with which, under our form of government, great military and naval establishments can be disbanded and expenses reduced from a war to a peace footing.

During the fiscal year ending June 30, 1866, the receipts were $558,032,620 and the expenditures $520,750,940, leaving an available surplus of $37,281,680. It is estimated that the receipts for the fiscal year ending the 30th June, 1867, will be $475,061,386, and that the expenditures will reach the sum of $316,428,078, leaving in the Treasury a surplus of $158,633,308. For the fiscal year ending June 30, 1886, it is estimated that the receipts will amount to $436,000,000 and that the expenditures will be $350,247,641, showing an excess of $85,752,359 in favor of the Government. These estimated receipts may be diminished by a reduction of excise and import duties, but after all necessary reductions shall have been made the revenue of the present and of following years will doubtless be sufficient to cover all legitimate charges upon the Treasury and leave a large annual surplus to be applied to the payment of the principal of the debt. There seems now to be no good reason why taxes may not be reduced as the country advances in population and wealth, and yet the debt be extinguished within the next quarter of a century.

The report of the Secretary of War furnishes valuable and important information in reference to the operations of his Department during the past year. Few volunteers now remain in the service, and they are being discharged as rapidly as they can be replaced by regular troops. The Army has been promptly paid, carefully provided with medical treatment, well sheltered and subsisted, and is to be furnished with breech-loading small arms. The military strength of the nation has been unimpaired by the discharge of volunteers, the disposition of unserviceable or perishable stores, and the retrenchment of expenditure. Sufficient war material to meet any emergency has been retained, and from the disbanded volunteers standing ready to respond to the national call large armies can be rapidly organized, equipped, and concentrated. Fortifications on the coast and frontier have received or are being prepared for more powerful armaments; lake surveys and harbor and river improvements are in course of energetic prosecution. Preparations have been made for the payment of the additional bounties authorized during the recent session of Congress, under such regulations as will protect the Government from fraud and secure to the honorably discharged soldier the well-earned reward of his faithfulness and gallantry. More than 6,000 maimed soldiers have received artificial limbs or other surgical apparatus, and 41 national cemeteries, containing the remains of 104,526 Union soldiers, have already been established. The total estimate of military appropriations is $25,205,669.

It is stated in the report of the Secretary of the Navy that the naval force at this time consists of 278 vessels, armed with 2,351 guns. Of these, 115 vessels, carrying 1,029 guns, are in commission, distributed chiefly among seven squadrons. The number of men in the service is 13,600. Great activity and vigilance have been displayed by all the squadrons, and their movements have been judiciously and efficiently arranged in such manner as would best promote American commerce and protect the rights and interests of our countrymen abroad. The vessels unemployed are undergoing repairs or are laid up until their services may be required. Most of the ironclad fleet is at League Island, in the vicinity of Philadelphia, a place which, until decisive action should be taken by Congress, was selected by the Secretary of the Navy as the most eligible location for that class of vessels. It is important that a suitable public station should be provided for the ironclad fleet. It is intended that these vessels shall be in proper condition for any emergency, and it is desirable that the bill accepting League Island for naval purposes, which passed the House of Representatives at its last session, should receive final action at an early period, in order that there may be a suitable public station for this class of vessels, as well as a navy-yard of area sufficient for the wants of the service on the Delaware River. The naval pension fund amounts to $11,750,000, having been increased $2,750,000 during the year. The expenditures of the Department for the fiscal year ending 30th June last were $43,324,526, and the estimates for the coming year amount to $23,568,436. Attention is invited to the condition of our seamen and the importance of legislative measures for their relief and improvement. The suggestions in behalf of this deserving class of our fellow-citizens are earnestly recommended to the favorable attention of Congress.

The report of the Postmaster-General presents a most satisfactory condition of the postal service and submits recommendations which deserve the consideration of Congress. The revenues of the Department for the year ending June 30, 1866, were $14,386,986 and the expenditures $15,352,079, showing an excess of the latter of $965,093. In anticipation of this deficiency, however, a special appropriation was made by Congress in the act approved July 28, 1866. Including the standing appropriation of $700,000 for free mail matter as a legitimate portion of the revenues, yet remaining unexpended, the actual deficiency for the past year is only $265,093—a sum within $51,141 of the amount estimated in the annual report of 1864. The decrease of revenue compared with the previous year was 1-1/5 per cent, and the increase of expenditures, owing principally to the enlargement of the mail service in the South, was 12 per cent. On the 30th of June last there were in operation 6,930 mail routes, with an aggregate length of 180,921 miles, an aggregate annual transportation of 71,837,914 miles, and an aggregate annual cost, including all expenditures, of $8,410,184. The length of railroad routes is 32,092 miles and the annual transportation 30,609,467 miles. The length of steamboat routes is 14,346 miles and the annual transportation 3,411,962 miles. The mail service is rapidly increasing throughout the whole country, and its steady extension in the Southern States indicates their constantly improving condition. The growing importance of the foreign service also merits attention. The post-office department of Great Britain and our own have agreed upon a preliminary basis for a new postal convention, which it is believed will prove eminently beneficial to the commercial interests of the United States, inasmuch as it contemplates a reduction of the international letter postage to one-half the existing rates; a reduction of postage with all other countries to and from which correspondence is transmitted in the British mail, or in closed mails through the United Kingdom; the establishment of uniform and reasonable charges for the sea and territorial transit of correspondence in closed mails; and an allowance to each post-office department of the right to use all mail communications established under the authority of the other for the dispatch of correspondence, either in open or closed mails, on the same terms as those applicable to the inhabitants of the country providing the means of transmission.

The report of the Secretary of the Interior exhibits the condition of those branches of the public service which are committed to his supervision. During the last fiscal year 4,629,312 acres of public land were disposed of, 1,892,516 acres of which were entered under the homestead act. The policy originally adopted relative to the public lands has undergone essential modifications. Immediate revenue, and not their rapid settlement, was the cardinal feature of our land system. Long experience and earnest discussion have resulted in the conviction that the early development of our agricultural resources and the diffusion of an energetic population over our vast territory are objects of far greater importance to the national growth and prosperity than the proceeds of the sale of the land to the highest bidder in open market. The preemption laws confer upon the pioneer who complies with the terms they impose the privilege of purchasing a limited portion of "unoffered lands" at the minimum price. The homestead enactments relieve the settler from the payment of purchase money, and secure him a permanent home upon the condition of residence for a term of years. This liberal policy invites emigration from the Old and from the more crowded portions of the New World. Its propitious results are undoubted, and will be more signally manifested when time shall have given to it a wider development.

Congress has made liberal grants of public land to corporations in aid of the construction of railroads and other internal improvements. Should this policy hereafter prevail, more stringent provisions will be required to secure a faithful application of the fund. The title to the lands should not pass, by patent or otherwise, but remain in the Government and subject to its control until some portion of the road has been actually built. Portions of them might then from time to time be conveyed to the corporation, but never in a greater ratio to the whole quantity embraced by the grant than the completed parts bear to the entire length of the projected improvement. This restriction would not operate to the prejudice of any undertaking conceived in good faith and executed with reasonable energy, as it is the settled practice to withdraw from market the lands falling within the operation of such grants, and thus to exclude the inception of a subsequent adverse right. A breach of the conditions which Congress may deem proper to impose should work a forfeiture of claim to the lands so withdrawn but unconveyed, and of title to the lands conveyed which remain unsold.

Operations on the several lines of the Pacific Railroad have been prosecuted with unexampled vigor and success. Should no unforeseen causes of delay occur, it is confidently anticipated that this great thoroughfare will be completed before the expiration of the period designated by Congress.

During the last fiscal year the amount paid to pensioners, including the expenses of disbursement, was $13,459,996, and 50,177 names were added to the pension rolls. The entire number of pensioners June 30, 1866, was 126,722. This fact furnishes melancholy and striking proof of the sacrifices made to vindicate the constitutional authority of the Federal Government and to maintain inviolate the integrity of the Union. They impose upon us corresponding obligations. It is estimated that $33,000,000 will be required to meet the exigencies of this branch of the service during the next fiscal year.
