Being somewhat weary I dropped down in the shady side of the ravine to rest and gazed up and down at the mute records of the past which were scattered around me. It seemed as if the monsters whose bones lay there were suddenly reincarnated. A group of Titanotheria seemed to be assembled in a vast body; the Rhinoceros, Oreodon, and diminutive horse such as lived in those parts, were gathered around, each apparently ready to tell its tale of events which no man ever had heard before. A Titanotherium Robustum, smacking its huge jaws, turned its dull eyes upward to the summit of the great bluff 700 feet above where I was resting, and then turning its gaze toward me, said, "What are you? You are the first specimen of your genus that has ever passed this way. How old are you?" "A score or two of years," I replied. There was a roar of grunts doubtless intended for laughter which echoed up and down the ravine, and the pachyderm looked at the oreodon and smiled. Continuing, the Titanotherium said, "Do you see the top of that lofty bluff?" I nodded yes. "Well, that is young, and it is not more than three or four decillion years since this country was pushed up and has been washing down the river. Before that, it was under water for nearly as long a period, because it was mighty slow work filling in all that 1,500 perpendicular feet of clay out of which all the layers of these bluffs are made." The Rhinoceros then grunted out his reminiscences, to the effect that all that occurred long after his day, because he was doing business before the beginning of that vast cycle when the country was so deep under water, and before these deposits were made. Continuing, he added, "Away back in those times a very bad spell of wet weather and floods occurred, when we all were caught and stuck in this swamp which finally dried up on all this great crowd of companions of a bygone age. Since we were washed out by the last winter and spring rains which swept down this gully we have seen nothing, and you are the first two-legged creature we ever saw, except a few dinosaurs, and but very few of them lived in these parts." After this dreamy colloquy I woke up from my little rest, and the shadows of the prehistoric pachyderms vanished, but the thousands of bones were still protruding from the walls of the deep ravine. "The waters stood upon the mountains; At Thy rebuke they fled; He uncovereth deep things out of darkness, And bringeth out to light the shadow of death."
