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.

They urged me to take up winter quarters at the forks of the Platt, stating that if I attempted to advance further until spring, I would endanger the lives of my whole party.

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.

I had the Big Horn river explored from Wind River mountain to my place of embarkation.

The only very rugged part of the route is in crossing the Big Horn mountain, which is about 30 miles wide.

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.

The snow continues with high winds we remain at this camp to day in consequence of the weather.
