In a period of profound peace the conduct of the mere military establishment forms but a very inconsiderable portion of the duties devolving upon the administration of the Department of War. It will be seen by the returns from the subordinate departments of the Army that every branch of the service is marked with order, regularity, and discipline; that from the commanding general through all the gradations of superintendence the officers feel themselves to have been citizens before they were soldiers, and that the glory of a republican army must consist in the spirit of freedom, by which it is animated, and of patriotism, by which it is impelled. It may be confidently stated that the moral character of the Army is in a state of continual improvement, and that all the arrangements for the disposal of its parts have a constant reference to that end. But to the War Department are attributed other duties, having, indeed, relation to a future possible condition of war, but being purely defensive, and in their tendency contributing rather to the security and permanency of peace--the erection of the fortifications provided for by Congress, and adapted to secure our shores from hostile invasion; the distribution of the fund of public gratitude and justice to the pensioners of the Revolutionary war; the maintenance of our relations of peace and protection with the Indian tribes, and the internal improvements and surveys for the location of roads and canals, which during the last three sessions of Congress have engaged so much of their attention, and may engross so large a share of their future benefactions to our country. By the act of April 30th, 1824, suggested and approved by my predecessor, the sum of $30,000 was appropriated for the purpose of causing to be made the necessary surveys, plans, and estimates of the routes of such roads and canals as the President of the United States might deem of national importance in a commercial or military point of view, or necessary for the transportation of the public mail. The surveys, plans, and estimates for each, when completed, will be laid before Congress. In execution of this act a board of engineers was immediately instituted, and have been since most assiduously and constantly occupied in carrying it into effect. The first object to which their labors were directed, by order of the late President, was the examination of the country between the tide waters of the Potomac, the Ohio, and Lake Erie, to ascertain the practicability of a communication between them, to designate the most suitable route for the same, and to form plans and estimates in detail of the expense of execution.
