Whenever we reached a height we surveyed the country both before and behind us, to make sure, in the first place, that no Indians were following; and, in the second, that none were encamped ahead, or, as I have before said, moving about.  During the day we met with several small streams at which we could water our horses and slake our own thirst; and the first night we encamped under shelter of a wood, where there was plenty of grass for our steeds.  We contented ourselves with forming a lean-to, but did not light a fire lest it should betray our whereabouts.  Having eaten a little more pemmican, we formed our beds of spruce-fir tops, and lay down to rest.
