Although the present organization of the Army and the administration of its various branches of service are, upon the whole, satisfactory, they are yet susceptible of much improvement in particulars, some of which have been heretofore submitted to the consideration of Congress, and others are now first presented in the report of the Secretary of War. The expediency of providing for additional numbers of officers in the two corps of engineers will in some degree depend upon the number and extent of the objects of national importance upon which Congress may think it proper that surveys should be made conformably to the act of April 30th, 1824. Of the surveys which before the last session of Congress had been made under the authority of that act, reports were made--Of the Board of Internal Improvement, on the Chesapeake and Ohio Canal. On the continuation of the national road from Cumberland to the tide waters within the District of Columbia. On the continuation of the national road from Canton to Zanesville. On the location of the national road from Zanesville to Columbus. On the continuation of the same to the seat of government in Missouri. On a post road from Baltimore to Philadelphia. Of a survey of Kennebec River (in part). On a national road from Washington to Buffalo. On the survey of Saugatuck Harbor and River. On a canal from Lake Pont Chartrain to the Mississippi River. On surveys at Edgartown, Newburyport, and Hyannis Harbor. On survey of La Plaisance Bay, in the Territory of Michigan. And reports are now prepared and will be submitted to Congress--On surveys of the peninsula of Florida, to ascertain the practicability of a canal to connect the waters of the Atlantic with the Gulf of Mexico across that peninsula; and also of the country between the bays of Mobile and of Pensacola, with the view of connecting them together by a canal. On surveys of a route for a canal to connect the waters of James and Great Kenhawa rivers. On the survey of the Swash, in Pamlico Sound, and that of Cape Fear, below the town of Wilmington, in North Carolina. On the survey of the Muscle Shoals, in the Tennessee River, and for a route for a contemplated communication between the Hiwassee and Coosa rivers, in the State of Alabama. Other reports of surveys upon objects pointed out by the several acts of Congress of the last and preceding sessions are in the progress of preparation, and most of them may be completed before the close of this session. All the officers of both corps of engineers, with several other persons duly qualified, have been constantly employed upon these services from the passage of the act of April 30th, 1824, to this time.
