No. 243.

Mr. Davis to Mr. Motley.

Department of State, Washington, August 15, 1870.

Sir: I transmit a copy of a letter of the 19th ultimo from the Treasury Department, inclosing one from the collector of customs of the United States at Pembina, upon the subject of the boundary between that portion of the possessions of the United States and Great Britain, extending from the Lake of the Woods to the Rocky Mountains, together with a copy of my reply of the 13th instant.

I will thank you to inform the British government of the discovery which has been made by the engineer officers of the United States, in regard to the true location of the boundary, as ascertained by the usual scientific method of determining such matters.

I am, sir, your obedient servant,

J. C. B. DAVIS, Acting Secretary.
