With these they crossed the mountains, to a distance of three or four hundred miles, to a fort on the south fork of the Platte river.

At this place they disposed of their blankets and cattle to great advantage, and Mr.Carson promptly returned to the companions he had left at Brown's Hole.

The traders undoubtedly received in payment the only currency of the country, beaver skins.

These they probably took with them to St.Louis for ultimate sale.

We know not how Mr.Carson invested his earnings.
