As twilight came on, the open space was deserted. The Folk were seeking the safety of the caves. Lop-Ear led the way to bed. High up the bluff we climbed, higher than all the other caves, to a tiny crevice that could not be seen from the ground. Into this Lop-Ear squeezed. I followed with difficulty, so narrow was the entrance, and found myself in a small rock-chamber. It was very low—not more than a couple of feet in height, and possibly three feet by four in width and length. Here, cuddled together in each other’s arms, we slept out the night. CHAPTER VI While the more courageous of the youngsters played in and out of the large-mouthed caves, I early learned that such caves were unoccupied. No one slept in them at night. Only the crevice-mouthed caves were used, the narrower the mouth the better. This was from fear of the preying animals that made life a burden to us in those days and nights. The first morning, after my night’s sleep with Lop-Ear, I learned the advantage of the narrow-mouthed caves. It was just daylight when old Saber-Tooth, the tiger, walked into the open space. Two of the Folk were already up. They made a rush for it. Whether they were panic-stricken, or whether he was too close on their heels for them to attempt to scramble up the bluff to the crevices, I do not know; but at any rate they dashed into the wide-mouthed cave wherein Lop-Ear and I had played the afternoon before. What happened inside there was no way of telling, but it is fair to conclude that the two Folk slipped through the connecting crevice into the other cave. This crevice was too small to allow for the passage of Saber-Tooth, and he came out the way he had gone in, unsatisfied and angry. It was evident that his night’s hunting had been unsuccessful and that he had expected to make a meal off of us. He caught sight of the two Folk at the other cave-mouth and sprang for them. Of course, they darted through the passageway into the first cave. He emerged angrier than ever and snarling. Pandemonium broke loose amongst the rest of us. All up and down the great bluff, we crowded the crevices and outside ledges, and we were all chattering and shrieking in a thousand keys. And we were all making faces—snarling faces; this was an instinct with us. We were as angry as Saber-Tooth, though our anger was allied with fear. I remember that I shrieked and made faces with the best of them. Not only did they set the example, but I felt the urge from within me to do the same things they were doing. My hair was bristling, and I was convulsed with a fierce, unreasoning rage.
