The cave which took my fancy lay halfway up the precipitous side of a lofty cliff. The way to it was such that I knew no extremely formidable beast could frequent it, nor was it large enough to make a comfortable habitat for any but the smaller mammals or reptiles. Yet it was with the utmost caution that I crawled within its dark interior. Here I found a rather large chamber, lighted by a narrow cleft in the rock above which let the sunlight filter in in sufficient quantities partially to dispel the utter darkness which I had expected. The cave was entirely empty, nor were there any signs of its having been recently occupied. The opening was comparatively small, so that after considerable effort I was able to lug up a bowlder from the valley below which entirely blocked it. Then I returned again to the valley for an armful of grasses and on this trip was fortunate enough to knock over an orthopi, the diminutive horse of Pellucidar, a little animal about the size of a fox terrier, which abounds in all parts of the inner world. Thus, with food and bedding I returned to my lair, where after a meal of raw meat, to which I had now become quite accustomed, I dragged the bowlder before the entrance and curled myself upon a bed of grasses—a naked, primeval, cave man, as savagely primitive as my prehistoric progenitors. I awoke rested but hungry, and pushing the bowlder aside crawled out upon the little rocky shelf which was my front porch. Before me spread a small but beautiful valley, through the center of which a clear and sparkling river wound its way down to an inland sea, the blue waters of which were just visible between the two mountain ranges which embraced this little paradise. The sides of the opposite hills were green with verdure, for a great forest clothed them to the foot of the red and yellow and copper green of the towering crags which formed their summit. The valley itself was carpeted with a luxuriant grass, while here and there patches of wild flowers made great splashes of vivid color against the prevailing green. Dotted over the face of the valley were little clusters of palmlike trees—three or four together as a rule. Beneath these stood antelope, while others grazed in the open, or wandered gracefully to a nearby ford to drink. There were several species of this beautiful animal, the most magnificent somewhat resembling the giant eland of Africa, except that their spiral horns form a complete curve backward over their ears and then forward again beneath them, ending in sharp and formidable points some two feet before the face and above the eyes. In size they remind one of a pure bred Hereford bull, yet they are very agile and fast. The broad yellow bands that stripe the dark roan of their coats made me take them for zebra when I first saw them. All in all they are handsome animals, and added the finishing touch to the strange and lovely landscape that spread before my new home.
