Many reasons may be urged for the establishment of these Posts, among which are the following: 1st. By means of such Posts, all acts of the Indians would be under a full and complete inspection. All cases of murder, theft, or other outrage would be brought to light and the proper punishment inflicted. 2nd. In most cases this may be done by giving the Chiefs a small fee that they may either punish the offenders themselves, or deliver them up to the commander of the Post. In such cases it should be held that their peers have adjudged them guilty before punishment is inflicted. 3rd. By means of these Posts it will become safe and easy for the smallest number to pass and repass from Oregon to the States; and with a civil magistrate at each Station, all idle wandering white men without passports can be sent out of the territory. 4th. In this way all banditti for robbing the mails or travelers would be prevented, as well as all vagabonds removed from among the Indians. 5th. Immigrants now lose horses and other stock by the Indians, commencing from the border of the States to the Willamette. It is much to the praise of our countrymen that they bear so long with the Indians when our Government has done so little to enable them to pass in safety. For one man to lose five or six horses is not a rare occurrence, which loss is felt heavily, when most of the family are compelled to walk, to favor a reduced and failing team. 6th. The Indians along the line take courage from the forbearance of the immigrants. The timid Indians on the Columbia have this year in open day attacked several parties of wagons, numbering from two to seven, and robbed them, being armed with guns, bows and arrows, knives and axes. Mr. Glenday from St. Charles, Mo., the bearer of this communication to the States, with Mr. Bear, his companion, rescued seven wagons from being plundered, and the people from gross insults, rescuing one woman, when the Indians were in the act of taking all the clothes from her person. The men were mostly stripped of their shirts and pantaloons at the time. 7th. The occasional supplies to passing immigrants, as well as the aid which may be afforded to the sick and needy, are not the least of the important results to follow from these establishments. A profitable exchange to the Posts and immigrants, as also to others journeying through the country, can be made by exchanging worn-out horses and cattle for fresh ones. 8th. It scarcely need be mentioned what advantage the Government will derive by a similar exchange for the transport of the mail, as also for the use of troops passing through. 9th. To suppress the use of ardent spirits among the Indians it will be requisite to regard the giving or furnishing of it in any manner as a breach of the laws and peace of the territory.
