In my collection, I have bits of cloth taken from a body which archaeologists date not later than 400 A. D. nor earlier than 8,000 B. C., and bits of corn and pottery from water jars, placed with the dead to sustain them on the long journey to the Other World. For the last year, I have worn a pin of obsidian which you would swear was an Egyptian scarab if I had not myself obtained it from the ossuaries of the Cave Dwellers in the American Southwest. Come out now to the cave door and look up and down the canyon again! To right and to left for a height of 500 feet the face of the yellow _tufa_ precipice is literally pitted with the windows and doors of the Stone Age City. In the bottom of the valley is a roofless dwelling of hundreds of rooms--"the cormorant and the bittern possess it; the owl also and the raven dwell in it; stones of emptiness; thorns in the palaces; nettles and brambles in the fortresses; and the screech owl shall rest there." Listen! You can almost hear it--the fulfillment of Isaiah's old prophecy--the lonely "hoo-hoo-hoo" of the turtle dove; and the lonelier cry of the eagle circling, circling round the empty doors of the upper cliffs! Then, the sharp, short bark-bark-bark of a fox off up the canyon in the yellow pine forests towards the white snows of the Jemez Mountains; and one night from my camp in this canyon, I heard the coyotes howling from the empty caves. Below are the roofless cities of the dead Stone Age, and the dancing floors, and the irrigation canals used to this day, and the stream leaping down from the Jemez snows, which must once have been a rushing torrent where wallowed such monsters as are known to-day only in modern men's dreams.
