Treaties have been concluded with the Indians, who, enticed into armed opposition to our Government at the outbreak of the rebellion, have unconditionally submitted to our authority and manifested an earnest desire for a renewal of friendly relations.

During the year ending September 30, 1866, 8,716 patents for useful inventions and designs were issued, and at that date the balance in the Treasury to the credit of the patent fund was $228,297.

As a subject upon which depends an immense amount of the production and commerce of the country, I recommend to Congress such legislation as may be necessary for the preservation of the levees of the Mississippi River. It is a matter of national importance that early steps should be taken, not only to add to the efficiency of these barriers against destructive inundations, but for the removal of all obstructions to the free and safe navigation of that great channel of trade and commerce.

The District of Columbia under existing laws is not entitled to that representation in the national councils which from our earliest history has been uniformly accorded to each Territory established from time to time within our limits. It maintains peculiar relations to Congress, to whom the Constitution has granted the power of exercising exclusive legislation over the seat of Government. Our fellow-citizens residing in the District, whose interests are thus confided to the special guardianship of Congress, exceed in number the population of several of our Territories, and no just reason is perceived why a Delegate of their choice should not be admitted to a seat in the House of Representatives. No mode seems so appropriate and effectual of enabling them to make known their peculiar condition and wants and of securing the local legislation adapted to them. I therefore recommend the passage of a law authorizing the electors of the District of Columbia to choose a Delegate, to be allowed the same rights and privileges as a Delegate representing a Territory. The increasing enterprise and rapid progress of improvement in the District are highly gratifying, and I trust that the efforts of the municipal authorities to promote the prosperity of the national metropolis will receive the efficient and generous cooperation of Congress.

The report of the Commissioner of Agriculture reviews the operations of his Department during the past year, and asks the aid of Congress in its efforts to encourage those States which, scourged by war, are now earnestly engaged in the reorganization of domestic industry.

It is a subject of congratulation that no foreign combinations against our domestic peace and safety or our legitimate influence among the nations have been formed or attempted. While sentiments of reconciliation, loyalty, and patriotism have increased at home, a more just consideration of our national character and rights has been manifested by foreign nations.

The entire success of the Atlantic telegraph between the coast of Ireland and the Province of Newfoundland is an achievement which has been justly celebrated in both hemispheres as the opening of an era in the progress of civilization. There is reason to expect that equal success will attend and even greater results follow the enterprise for connecting the two continents through the Pacific Ocean by the projected line of telegraph between Kamchatka and the Russian possessions in America.

The resolution of Congress protesting against pardons by foreign governments of persons convicted of infamous offenses on condition of emigration to our country has been communicated to the states with which we maintain intercourse, and the practice, so justly the subject of complaint on our part, has not been renewed.

The congratulations of Congress to the Emperor of Russia upon his escape from attempted assassination have been presented to that humane and enlightened ruler and received by him with expressions of grateful appreciation.

The Executive, warned of an attempt by Spanish American adventurers to induce the emigration of freedmen of the United States to a foreign country, protested against the project as one which, if consummated, would reduce them to a bondage even more oppressive than that from which they have just been relieved. Assurance has been received from the Government of the State in which the plan was matured that the proceeding will meet neither its encouragement nor approval. It is a question worthy of your consideration whether our laws upon this subject are adequate to the prevention or punishment of the crime thus meditated.
