62 LETTER TO LIEUTENANT DONELSON. 
It is important that attention should be given to collections, and particularly to the mineral 
wealth of the region. Gold is said to be found in the neighborhood of the Hell Gate fork. I 
desire you to pay especial attention to the Indian duties connected with your position. You are 
authorized to pay an interpreter at the rate of $500 per year. He should, as you have suggested, 
be a guide; and the Flathead, Gahiel, is recommended as competent and reliable: endeavor to 
secure his services. Your attention is called to the several particulars in relation to which I am 
directed to make reports in the instructions of the Commissioner of Indian Affairs, and any 
information you can afford will be of service. Make an estimate of the probable cost of estab- 
lishing a sub-agency, and the general cost of keeping it up. I shall, however, endeavor to 
communicate with you again this fall, and may be able to send you additional Indian goods. 
To Lieutenant Grover, who has volunteered to conduct the dog train over these mountains in 
the winter, and to Mr. Tinkham, who has volunteered to cross the mountains twice by the 
Marias Pass to Fort Benton, and thence by some soutbern pass to this point, and thence by the 
southern Nez Perces to Wallah-Wallah, you will, of course, render all the assistance in your 
power. Ample supplies have been provided for them, and I do not think any contingency will 
arise making it necessary that they should encroach upon your stores. 
By Lieutenant Grover and Mr. Tinkham, I hope you will be able to send reports of your 
operations, or detached reports, with a statement of your route from Fort Benton to this point, 
and of your survey to Fort Hall, should it be accomplished before the arrival of Lieutenant 
Grover. 
You may rely upon my establishing at least a bi-monthly express there this winter, if practi- 
cable, and by which I shall be able to hear from you twice, and perhaps three times, before I 
see you in the spring. I shall endeavor to visit this place previous to the 15th of June. 
Of the animals (horses and mules) left in your charge, I am confident that as many of them 
will be serviceable, in a few days, as your duties will require. Should the winter prove mild, 
all the animals will probably be serviceable in the spring. For the meat rations you will rely 
mainly upon beef, which is in abundance in this valley. Lieutenant Saxton established the 
tariff at $60 per head, which meets my approval. 
Yours, truly, 
ISAAC I. STEVENS. 
Lieutenant Muuuan.
