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.

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.

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.

Snow is so common that I have omitted to note its falling at least two days out of Three.

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