You will also ascertain, as far as in your power, the number of Indians on the line between Red River and the Rocky Mountains; the different nations and tribes into which they are divided and the particular locality inhabited, and the language spoken, and also the names of the principal chiefs of each tribe. In doing this you will be careful to obtain the information without in any manner leading the Indians to suppose you are acting under authority, or inducing them to form any expectations based on your inquiries. You will also be expected to ascertain, as far as possible, the nature of the trade in furs conducted upon the Saskatchewan, the number and nationality of the persons employed in what has been called the Free Trade there, and what portion of the supplies, if any, come from the United States territory, and what portion of the furs are sent thither; and generally to make such inquiries as to the source of trade in that region as may enable the Lieutenant-Governor to form an accurate idea of the commerce of the Saskatchewan. You are to report from time to time as you proceed westward, and forward your communications by such opportunities as may occur. The Lieutenant-Governor will rely upon your executing this mission with all reasonable despatch. (Signed) S. W. HILL, P. Secretary. LIEUTENANT BUTLER'S REPORT. INTRODUCTORY. The Hon. Adams G.
