The bill providing for the negotiation of these treaties was passed unanimously by the Senate, but "the unhappy difficulties existing on the subject of slavery" delayed it in the House until it was too late to be carried into effect.
All the tribes had been informed of this pending bill, and were looking forward to it with great interest and anxiety. In 1849 they had all expressed themselves as "very anxious to be instructed in agriculture and the civilized arts." Already the buffalo herds were thinning and disappearing. From time immemorial the buffalo had furnished them food, clothing, and shelter; with its disappearance, starvation stared them in the face, and they knew it. There can be no doubt that at this time all the wild tribes of the Upper Missouri region—the Sioux, Cheyennes, Arapahoes—were ready and anxious to establish friendly relations with the United States Government, and to enter into some arrangement by which some means of future subsistence, and some certainty of lands enough to live on, could be secured to them. Meantime they hunted with greater diligence than ever; and in this one year alone had sold to the fur-traders within the limits of one agency $330,000 worth of buffalo-robes, and "furs, peltries, and miscellaneous goods to the amount of $60,000. What they thus receive for their furs, robes, etc., would be ample for their support," says Hatton, "were it not that they have to give such exorbitant prices for what they purchase from the whites."
In the winter and spring of 1850 all these tribes were visited by an agent of the Government. He reported them as "friendly disposed," but very impatient to come to some understanding about the right of way. "This is what the Indians want, and what they are anxious about; having been told long since, and so often repeated by travellers passing (who care little about the consequences of promises so they slip through safely and unmolested themselves), that their 'Great Father' would soon reward them liberally for the right of way, the destruction of timber, game, etc., as well as for any kindness shown Americans passing through their country."
In the summer of 1851 this much desired treaty was made. Seven of the prairie and mountain tribes gathered in great force at Fort Laramie. The report of this council contains some interesting and noticeable points.
