The national debt has been reduced to the extent of $86,057,126.80 during the year, and by the negotiation of national bonds at a lower rate of interest the interest on the public debt has been so far diminished that now the sum to be raised for the interest account is nearly $17,000,000 less than on the 1st of March, 1869. It was highly desirable that this rapid diminution should take place, both to strengthen the credit of the country and to convince its citizens of their entire ability to meet every dollar of liability without bankrupting them. But in view of the accomplishment of these desirable ends; of the rapid development of the resources of the country; its increasing ability to meet large demands, and the amount already paid, it is not desirable that the present resources of the country should continue to be taxed in order to continue this rapid payment. I therefore recommend a modification of both the tariff and internal-tax law. I recommend that all taxes from internal sources be abolished, except those collected from spirituous, vinous, and malt liquors, tobacco in its various forms, and from stamps.

In readjusting the tariff I suggest that a careful estimate be made of the amount of surplus revenue collected under the present laws, after providing for the current expenses of the Government, the interest account, and a sinking fund, and that this surplus be reduced in such a manner as to afford the greatest relief to the greatest number. There are many articles not produced at home, but which enter largely into general consumption through articles which are manufactured at home, such as medicines compounded, etc., etc., from which very little revenue is derived, but which enter into general use. All such articles I recommend to be placed on the "free list." Should a further reduction prove advisable, I would then recommend that it be made upon those articles which can best bear it without disturbing home production or reducing the wages of American labor.

I have not entered into figures, because to do so would be to repeat what will be laid before you in the report of the Secretary of the Treasury. The present laws for collecting revenue pay collectors of customs small salaries, but provide for moieties (shares in all seizures), which, at principal ports of entry particularly, raise the compensation of those officials to a large sum. It has always seemed to me as if this system must at times work perniciously. It holds out an inducement to dishonest men, should such get possession of those offices, to be lax in their scrutiny of goods entered, to enable them finally to make large seizures. Your attention is respectfully invited to this subject.

Continued fluctuations in the value of gold, as compared with the national currency, has a most damaging effect upon the increase and development of the country, in keeping up prices of all articles necessary in everyday life. It fosters a spirit of gambling, prejudicial alike to national morals and the national finances. If the question can be met as to how to get a fixed value to our currency, that value constantly and uniformly approaching par with specie, a very desirable object will be gained.

For the operations of the Army in the past year, the expense of maintaining it, the estimate for the ensuing year, and for continuing seacoast and other improvements conducted under the supervision of the War Department, I refer you to the accompanying report of the Secretary of War.

I call your attention to the provisions of the act of Congress approved March 3, 1869, which discontinues promotions in the staff corps of the Army until provided for by law. I recommend that the number of officers in each grade in the staff corps be fixed, and that whenever the number in any one grade falls below the number so fixed, that the vacancy may be filled by promotion from the grade below. I also recommend that when the office of chief of a corps becomes vacant the place may be filled by selection from the corps in which the vacancy exists.

The report of the Secretary of the Navy shows an improvement in the number and efficiency of the naval force, without material increase in the expense of supporting it. This is due to the policy which has been adopted, and is being extended as fast as our material will admit, of using smaller vessels as cruisers on the several stations. By this means we have been enabled to occupy at once a larger extent of cruising grounds, to visit more frequently the ports where the presence of our flag is desirable, and generally to discharge more efficiently the appropriate duties of the Navy in time of peace, without exceeding the number of men or the expenditure authorized by law.

During the past year the Navy has, in addition to its regular service, supplied the men and officers for the vessels of the Coast Survey, and has completed the surveys authorized by Congress of the isthmuses of Darien and Tehuantepec, and, under like authority, has sent out an expedition, completely furnished and equipped, to explore the unknown ocean of the north.

The suggestions of the report as to the necessity for increasing and improving the matériel of the Navy, and the plan recommended for reducing the personnel of the service to a peace standard, by the gradual abolition of certain grades of officers, the reduction of others, and the employment of some in the service of the commercial marine, are well considered and deserve the thoughtful attention of Congress.

I also recommend that all promotions in the Navy above the rank of captain be by selection instead of by seniority. This course will secure in the higher grades greater efficiency and hold out an incentive to young officers to improve themselves in the knowledge of their profession.
