Mounting, therefore, we made the beat pace our pack animals could stand up through the eight miles of the narrows, riding well apart from each other, the only safeguard we could take, all craning our necks for view of the cliff crests ahead of us. But no living thing showed save a few deer and coyotes, and two mountain lions that, alarmed by our clattering pace, slipped past us back down the gorge. When at last we reached the end of the narrows and the canon broadened to a width of several hundred yards, all but fifty or seventy-five yards of the belt of timber lining the stream along the south wall being comparatively level grassy bunch land, nearly devoid of cover, we congratulated ourselves that we had not been scared into a retreat. Keen to put as much distance as we could between us and the Lipans, we travelled on up the canon at a sharp trot, keeping well to its middle, until about 5 p.m., when we reached a point where it widened into a broad bay, nearly seven hundred yards from crest to crest, with a dense thicket of mesquite trees near its centre that made fine shelter and an excellent point of defence for a night camp. The stream hugged the east wall of the canon, where it had carved out a tortuous bed perhaps one hundred and fifty yards wide, and so deep below the bench we occupied that only the tops of tall cottonwoods were visible from the thicket. While the rest of us were busy unsaddling and unpacking, Thornton slung all our canteens over his shoulder, and started for the stream. But no sooner had he disappeared below the edge of the bench, a scant two hundred yards from our camp, before a rapid rifle fire opened which, while we knew it must proceed from his direction, echoed back from one cliff wall to the other until it appeared like an attack on our position from all sides, while the echoes multiplied to the volume of cannon fire at the sound of each shot. Indeed, never have I heard such thunderous, crashing, ear-splitting gun-detonations except on one other occasion, when aboard the British battle ship _Invincible_ and in her six-inch gun battery while a salute was being fired.
