M. Motley to Mr. Fish.
Sir: Deferring to your No. 245, of 15th August, (which dispatch I beg to note did not reach me until 28th ultimo,) I have now the honor to transmit the copy of a letter which I have this day addressed to Earl Granville, notifying him of the discovery made this spring by the United States military commission under General Sykes, as to the true location of the boundary line along the forty-ninth parallel between the British North American possessions and the United States.
Copies of the documents, transcripts of which were sent me in your above-cited dispatch, were annexed to my communication with Lord Granville.
