The emigrants are from different States, but principally from Missouri, Arkansas, Illinois and New York. The majority of them are farmers, lured by the prospect of bounty in lands, by the reported fertility of the soil, and by the desire to be first among those who are planting our institutions on the Pacific Coast. Among them are artisans of every trade, comprising, with farmers, the very best material for a new colony. As pioneers, these people have undergone incredible hardships, and having now safely passed the Blue Mountain Range with their wagons and effects, have established a durable road from Missouri to Oregon, which will serve to mark permanently the route for larger numbers, each succeeding year, while they have practically demonstrated that wagons drawn by horses or oxen can cross the Rocky Mountains to the Columbia River, contrary to all the sinister assertions of all those who pretended it to be impossible.

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.

There are very eligible places for as many of these as the Government will find necessary, at suitable distances, not further than one or two hundred miles apart, at the main crossing of the principal streams that now form impediments to the journey, and consequently well supplied with water, having alluvial bottom lands of a rich quality, and generally well wooded. If I might be allowed to suggest, the best sites for said posts, my personal knowledge and observation enable me to recommend first, the main crossing of the Kansas River, where a ferry would be very convenient to the traveler, and profitable to the station having it in charge; next, and about eighty miles distant, the crossing of the Blue River, where in times of unusual freshet, a ferry would be in like manner useful; next and distant from one hundred to one hundred and fifty miles from the last mentioned, the Little Blue, or Republican Fork of the Kansas; next, and from sixty to one hundred miles distant from the last mentioned, the point of intersection of the Platte River; next, and from one hundred to one hundred and fifty miles distant from the last mentioned, crossing of the South Fork of the Platte River; next, and about one hundred and eighty or two hundred miles distant from the last mentioned, Horseshoe Creek, which is about forty miles west of Laramie's Fork in the Black Hills. Here is a fine creek for mills and irrigation, good land for cultivation, fine pasturage, timber and stone for building. Other locations may be had along the Platte and Sweetwater, on the Green River, or Black's Forks of the Bear River, near the great Soda Springs, near Fort Hall, and at suitable places down to the Columbia. These localities are all of the best description, so situated as to hold a ready intercourse with the Indians in their passage to and from the ordinary buffalo hunting grounds, and in themselves so well situated in all other respects as to be desirable to private enterprise if the usual advantage of trade existed. Any of the farms above indicated would be deemed extremely valuable in the States.

The Government cannot long overlook the importance of superintending the savages that endanger this line of travel, and that are not yet in treaty with it. Some of these are already well known to be led by desperate white men and mongrels, who form bandits in the most difficult passes, and are at all times ready to cut off some lagging emigrant in the rear of the party, or some adventurous one who may proceed a few miles in advance, or at night to make a descent upon the sleeping camp and carry away or kill horses and cattle. This is the case even now in the commencement of our western immigration, and when it comes to be more generally known that large quantities of valuable property and considerable sums of money are yearly carried over this desolate region, it is feared that an organized banditti will be instituted. The posts in contemplation would effectually counteract this. For the purpose they need not, or ought not, to be military establishments. The trading posts in this country have never been of such a character, and yet with very few men in them, have for years kept the surrounding Indians in the most pacific disposition, so that the traveler feels secure from molestation upon approaching Fort Laramie, Bridger's Fort, Fort Hall, etc., etc. The same can be obtained without any considerable expenditure by the Government, while by investing the officers in charge with competent authority, all evil-disposed white men, refugees from justice, or discharged vagabonds from trading posts might be easily removed from among the Indians and sent to the appropriate States for trial. The Hudson Bay Company's system of rewards among the savages would soon enable the posts to root out these desperadoes. A direct and friendly intercourse with all the tribes, even to the Pacific, might be thus maintained; the Government would become more intimately acquainted with them, and they with the Government, and instead of sending to the State courts a manifestly guilty Indian to be arraigned before a distant tribunal and acquitted for the want of testimony, by the technicalities of lawyers and of the law unknown to them, and sent back into the wilderness loaded with presents as an inducement to further crime, the post should be enabled to execute summary justice, as if the criminal had been already condemned by his tribe, because the tribe will be sure to deliver up none but the party whom they know to be guilty. They will in that way receive the trial of their peers, and secure within themselves to all intents and purposes, if not technically the trial by jury, yet the spirit of that trial. There are many powers which ought to reside in some person on this extended route for the convenience and even necessity of the public.

In this the emigrant and the people of Oregon are no more interested than the resident inhabitants of the States. At present no person is authorized to administer an oath, or legally attest a fact, from the western line of Missouri to the Pacific. The immigrant cannot dispose of his property at home, although an opportunity ever so advantageous to him should occur after he passes the western border of Missouri. No one can here make a legal demand and protest of a promissory note or bill of exchange. No one can secure the valuable testimony of a mountaineer, or an immigrating witness after he has entered this, at present, lawless country. Causes do exist and will continually arise, in which the private rights of citizens are, and will be, seriously prejudiced by such an utter absence of legal authority. A contraband trade from Mexico, the introduction from that country of liquors to be sold among the Indians west of the Kansas River, is already carried on with the mountain trappers, and very soon the teas, silks, nankeens, spices, camphor and opium of the East Indies will find their way, duty free, through Oregon, across the mountains and into the States, unless Custom House officers along this line find an interest in intercepting them.

Your familiarity with the Government policy, duties and interest renders it unnecessary for me to more than hint at the several objects intended by the enclosed bill, and any enlargement upon the topics here suggested as inducements to its adoption would be quite superfluous, if not impertinent. The very existence of such a system as the one above recommended suggests the utility of postoffices and mail arrangements, which it is the wish of all who now live in Oregon to have granted them; and I need only add that contracts for this purpose will be readily taken at reasonable rates for transporting the mail across from Missouri to the mouth of the Columbia in forty days, with fresh horses at each of the contemplated posts. The ruling policy proposed regards the Indians as the police of the country, who are to be relied upon to keep the peace, not only for themselves, but to repel lawless white men and prevent banditti, under the solitary guidance of the superintendents of the several posts, aided by a well directed system to induce the punishment of crime. It will only be after the failure of these means to procure the delivery or punishment of violent, lawless and savage acts of aggression, that a band or tribe should be regarded as conspirators against the peace, or punished accordingly by force of arms.

Hoping that these suggestions may meet your approbation, and conduce to the future interest of our growing country, I have the honor to be, Honorable Sir,

Your obedient servant,
MARCUS WHITMAN.
