hollow there; the Indians must have gone that way, if they went anywhere about here."
We reached the gap, which was like a deep notch cut into the mountain-ridge, and here we soon found an ant-hill furrowed with the mark of a lodge-pole. This was quite enough; there could be no doubt now. As we rode on, the opening growing narrower, the Indians had been compelled to march in closer order, and the traces became numerous and distinct. The gap terminated in a rocky gateway, leading into a rough and steep defile between two precipitous mountains. Here grass and weeds were bruised to fragments by the throng that had passed through. We moved slowly over the rocks, up the passage; and in this toilsome manner we advanced for an hour or two, bare precipices, hundreds of feet high, shooting up on either hand.
