These people were well dressed in skins, had some guns, but armed generally with bows and arrows and such other instruments of war as are common among the Indians of the Missouri.
Having now reached a point where danger might be reasonably apprehended from strolling war parties of Indians, spies were kept in advance and strict diligence observed in the duty of sentinels.
Several speeches were made by the chiefs during the council, all expressive in the highest degree of their friendly disposition towards our government, and their conduct in every particular manifested the sincerity of their declarations.
We continued to move forward without loss of time, hoping to be able to reach the wood described by the Indians before all our horses should become exhausted.
After an unremitting and severe labour of two days, we returned to our old encampment with the loss of some of my horses, and my men excessively fatigued.
After the departure of the land parties, I embarked with six men on thursday, the 21st april, on board my newly made boat and began the descent of the river.
As my men could profitably employ themselves on these streams, I moved slowly along, averaging not more than five or six miles per day and sometimes remained two days at the same encampment.
We were therefore obliged to unload our boats of their cargoes and pass them empty over the falls by means of long cords which we had provided for such purposes.
I had the Big Horn river explored from Wind River mountain to my place of embarkation.
These mountains appear to be almost entirely composed of stratas of rock of various colours (mostly red) and are partially covered with a dwarfish growth of pine and cedar, which are the only species of timber to be seen.
The principal or highest part of the mountain having changed its direction to east and west, I ascended it in such manner as to leave its most elevated ranges to the south and travelled north west over a very rough and broken country generally covered with snow.
