The Indians told us that during the night the wolves had come back; probably to devour the carcasses of their slain companions.  It was thought probable that they had returned up the river.  One of the men went out to ascertain this, and on coming back told us that the first surmise was correct--that the pack had indeed gone up the river, but that it had afterwards gone down again, as was evident from the bloody marks left by their feet.
