To the Senate of the United States:
I lay before the Senate, for its constitutional action thereon, a treaty concluded on the 7th day of October, 1863, at Conejos, Colorado Territory, between John Evans, governor and ex officio superintendent of Indian affairs of said Territory; Michael Steck, superintendent of Indian affairs for the Territory of New Mexico: Simeon Whitely and Lafayette Head, Indian agents, commissioners on the part of the United States, and the chiefs and warriors of the Tabeguache band of Utah Indians.
I also transmit a report of the Secretary of the Interior of the 12th instant, submitting the treaty; an extract from the last annual report of Governor Evans, of Colorado Territory, relating to its negotiation, and a map upon which is delineated the boundaries of the country ceded by the Indians and that retained for their own use.
ABRAHAM LINCOLN.
