I herewith communicate to Congress copies of a communication received from the chief magistrate of the State of Maryland in respect to the cession to that State of the interest of the General Government in the Chesapeake and Ohio Canal. Having no authority to enter into the proposed negotiation, I can only submit the subject to the consideration of Congress. That body will, I am confident, give to it a careful and favorable consideration and adopt such measures in the premises within their competency as will be just to the State of Maryland and to all the other interests involved.

M. VAN BUREN.

WASHINGTON CITY, January 8, 1840.

In addition to the papers accompanying my messages of the 23d and 30th ultimo, I communicate to Congress a copy of a letter, with its inclosure, since received at the Department of State from the governor of Iowa, in relation to the disputed boundary between that Territory and the State of Missouri.
