By the act of the 30th of April, 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.

On the 3d of February, 1825, they made their first report, which was immediately communicated to Congress, and in which they declared that having maturely considered the circumstances observed by them personally, and carefully studied the results of such of the preliminary surveys as were then completed, they were decidedly of opinion that the communication was practicable.

At the last session of Congress, before the board of engineers were enabled to make up their second report containing a general plan and preparatory estimate for the work, the Committee of the House of Representatives upon Roads and Canals closed the session with a report expressing the hope that the plan and estimate of the board of engineers might at this time be prepared, and that the subject be referred to the early and favorable consideration of Congress at their present session.  That expected report of the board of engineers is prepared, and will forthwith be laid before you.

Under the resolution of Congress authorizing the Secretary of War to have prepared a complete system of cavalry tactics, and a system of exercise and instruction of field artillery, for the use of the militia of the United States, to be reported to Congress at the present session, a board of distinguished officers of the Army and of the militia has been convened, whose report will be submitted to you with that of the Secretary of War.  The occasion was thought favorable for consulting the same board, aided by the results of a correspondence with the governors of the several States and Territories and other citizens of intelligence and experience, upon the acknowledged defective condition of our militia system, and of the improvements of which it is susceptible.  The report of the board upon this subject is also submitted for your consideration.
