In their slow progress, these persons have encountered, as in all former instances, and as all succeeding emigrants must, if this or some similar bill be not passed by Congress, the continual fear of Indian aggression, the actual loss through them of horses, cattle and other property, and the great labor of transporting an adequate amount of provisions for so long a journey. The bill herewith proposed would, in a great measure, lessen these inconveniences by the establishment of posts, which, while having the possessed power to keep the Indians in check, thus doing away with the necessity of military vigilance on the part of the traveler by day and night, would be able to furnish them in transit with fresh supplies of provisions, diminishing the original burdens of the emigrants, and finding thus a ready and profitable market for their produce--a market that would, in my opinion, more than suffice to defray all the current expenses of such post. The present party is supposed to have expended no less than $2,000 at Laramie's and Bridger's Forts, and as much more at Fort Hall and Fort Boise, two of the Hudson Bay Company's stations. These are at present the only stopping places in a journey of 2,200 miles, and the only place where additional supplies can be obtained, even at the enormous rate of charge, called mountain prices, i. e., $50 the hundred for flour, and $50 the hundred for coffee; the same for sugar, powder, etc. Many cases of sickness and some deaths took place among those who accomplished the journey this season, owing, in a great measure, to the uninterrupted use of meat, salt and fresh, with flour, which constitute the chief articles of food they are able to convey on their wagons, and this could be obviated by the vegetable productions which the posts in contemplation could very profitably afford them. Those who rely on hunting as an auxiliary support, are at present unable to have their arms repaired when out of order; horses and oxen become tender-footed and require to be shod on this long journey, sometimes repeatedly, and the wagons repaired in a variety of ways. I mention these as valuable incidents to the proposed measure, as it will also be found to tend in many other incidental ways to benefit the migratory population of the United States choosing to take this direction, and on these accounts, as well as for the immediate use of the posts themselves, they ought to be provided with the necessary shops and mechanics, which would at the same time exhibit the several branches of civilized art to the Indians. The outlay in the first instance would be but trifling. Forts like those of the Hudson Bay Company's surrounded by walls enclosing all the buildings, and constructed almost entirely of adobe, or sun-dried bricks, with stone foundations only, can be easily and cheaply erected.
