I transmit, for the constitutional action of the Senate, a supplemental
article to the Pottawatomie treaty of November 15, 1861, concluded on
the 29th ultimo, together with the accompanying communications from the
Secretary of the Interior and Commissioner of Indian Affairs.

ANDREW JOHNSON.



WASHINGTON, D.C., _April 7, 1866_.

_To the House of Representatives of the United States_:

I transmit a communication from the Secretary of the Interior, with the
accompanying papers, in reference to grants of land made by acts of
Congress passed in the years 1850, 1853, and 1856 to the States of
Mississippi, Alabama, Arkansas, Florida, and Louisiana, to aid in
the construction of certain railroads. As these acts will expire by
limitation on the 11th day of August, 1866, leaving the roads for
whose benefit they were conferred in an unfinished condition, it is
recommended that the time within which they may be completed be extended
for a period of five years.

ANDREW JOHNSON.



WASHINGTON, _April 11, 1866_.

_To the Senate of the United States_:
