To the Senate and House of Representatives:
In carrying fully into effect the intention of Congress in making an appropriation of $5,000 by the act of the 14th April, 1820, for the survey of the Ohio and the Mississippi rivers from the Rapids of the Ohio at Louisville to the Balize, for the purpose of facilitating and ascertaining the most practicable route of improving the navigation of these rivers, orders were given through the proper department to the Board of Engineers to examine and survey the said rivers with reference to those objects, and to report their opinion thereon, which they have done, and which report I now communicate for the information of Congress.
