The number of pensioners still continues to decrease, the highest number having been reached during the year ending June 30, 1873. During the last year 11,557 names were added to the rolls, and 12,977 were dropped therefrom, showing a net decrease of 1,420. But while the number of pensioners has decreased, the annual amount due on the pension rolls has increased $44,733.13. This is caused by the greatly increased average rate of pensions, which, by the liberal legislation of Congress, has increased from $90.26 in 1872 to $103.91 in 1875 to each invalid pensioner, an increase in the average rate of 15 per cent in the three years. During the year ending June 30, 1875, there was paid on account of pensions, including the expenses of disbursement, $29,683,116, being $910,632 less than was paid the preceding year. This reduction in amount of expenditures was produced by the decrease in the amount of arrearages due on allowed claims and on pensions the rate of which was increased by the legislation of the preceding session of Congress. At the close of the last fiscal year there were on the pension rolls 234,821 persons, of whom 210,363 were army pensioners, 105,478 being invalids and 104,885 widows and dependent relatives; 3,420 were navy pensioners, of whom 1,636 were invalids and 1,784 widows and dependent relatives; 21,038 were pensioners of the War of 1812, 15,875 of whom were survivors and 5,163 were widows.

It is estimated that $29,535,000 will be required for the payment of pensions for the next fiscal year, an amount $965,000 less than the estimate for the present year.

The geological explorations have been prosecuted with energy during the year, covering an area of about 40,000 square miles in the Territories of Colorado, Utah, and New Mexico, developing the agricultural and mineral resources and furnishing interesting scientific and topographical details of that region.

The method for the treatment of the Indians adopted at the beginning of my first term has been steadily pursued, and with satisfactory and encouraging results. It has been productive of evident improvement in the condition of that race, and will be continued, with only such modifications as further experience may indicate to be necessary.

The board heretofore appointed to take charge of the articles and materials pertaining to the War, the Navy, the Treasury, the Interior, and the Post-Office Departments, and the Department of Agriculture, the Smithsonian Institution, and the Commission of Food Fishes, to be contributed, under the legislation of last session, to the international exhibition to be held at Philadelphia during the centennial year 1876, has been diligent in the discharge of the duties which have devolved upon it; and the preparations so far made with the means at command give assurance that the governmental contribution will be made one of the marked characteristics of the exhibition. The board has observed commendable economy in the matter of the erection of a building for the governmental exhibit, the expense of which it is estimated will not exceed, say, $80,000. This amount has been withdrawn, under the law, from the appropriations of five of the principal Departments, which leaves some of those Departments without sufficient means to render their respective practical exhibits complete and satisfactory. The exhibition being an international one, and the Government being a voluntary contributor, it is my opinion that its contribution should be of a character, in quality and extent, to sustain the dignity and credit of so distinguished a contributor. The advantages to the country of a creditable display are, in an international point of view, of the first importance, while an indifferent or uncreditable participation by the Government would be humiliating to the patriotic feelings of our people themselves. I commend the estimates of the board for the necessary additional appropriations to the favorable consideration of Congress.

The powers of Europe almost without exception, many of the South American States, and even the more distant Eastern powers have manifested their friendly sentiments toward the United States and the interest of the world in our progress by taking steps to join with us in celebrating the centennial of the nation, and I strongly recommend that a more national importance be given to this exhibition by such legislation and by such appropriation as will insure its success. Its value in bringing to our shores innumerable useful works of art and skill, the commingling of the citizens of foreign countries and our own, and the interchange of ideas and manufactures will far exceed any pecuniary outlay we may make.

I transmit herewith the report of the Commissioner of Agriculture, together with the reports of the Commissioners, the board of audit, and the board of health of the District of Columbia, to all of which I invite your attention.

The Bureau of Agriculture has accomplished much in disseminating useful knowledge to the agriculturist, and also in introducing new and useful productions adapted to our soil and climate, and is worthy of the continued encouragement of the Government.

The report of the Commissioner of Education, which accompanies the report of the Secretary of the Interior, shows a gratifying progress in educational matters.

In nearly every annual message that I have had the honor of transmitting to Congress I have called attention to the anomalous, not to say scandalous, condition of affairs existing in the Territory of Utah, and have asked for definite legislation to correct it. That polygamy should exist in a free, enlightened, and Christian country, without the power to punish so flagrant a crime against decency and morality, seems preposterous. True, there is no law to sustain this unnatural vice; but what is needed is a law to punish it as a crime, and at the same time to fix the status of the innocent children, the offspring of this system, and of the possibly innocent plural wives. But as an institution polygamy should be banished from the land.
