Thus was momentum gained in the Younger World. But we were without this momentum. We were just getting started, and we could not go far in a single generation. We were without weapons, without fire, and in the raw beginnings of speech. The device of writing lay so far in the future that I am appalled when I think of it. Even I was once on the verge of a great discovery. To show you how fortuitous was development in those days let me state that had it not been for the gluttony of Lop-Ear I might have brought about the domestication of the dog. And this was something that the Fire People who lived to the northeast had not yet achieved. They were without dogs; this I knew from observation. But let me tell you how Lop-Ear’s gluttony possibly set back our social development many generations. Well to the west of our caves was a great swamp, but to the south lay a stretch of low, rocky hills. These were little frequented for two reasons. First of all, there was no food there of the kind we ate; and next, those rocky hills were filled with the lairs of carnivorous beasts. But Lop-Ear and I strayed over to the hills one day. We would not have strayed had we not been teasing a tiger. Please do not laugh. It was old Saber-Tooth himself. We were perfectly safe. We chanced upon him in the forest, early in the morning, and from the safety of the branches overhead we chattered down at him our dislike and hatred. And from branch to branch, and from tree to tree, we followed overhead, making an infernal row and warning all the forest-dwellers that old Saber-Tooth was coming. We spoiled his hunting for him, anyway. And we made him good and angry. He snarled at us and lashed his tail, and sometimes he paused and stared up at us quietly for a long time, as if debating in his mind some way by which he could get hold of us. But we only laughed and pelted him with twigs and the ends of branches. This tiger-baiting was common sport among the folk. Sometimes half the horde would follow from overhead a tiger or lion that had ventured out in the daytime. It was our revenge; for more than one member of the horde, caught unexpectedly, had gone the way of the tiger’s belly or the lion’s. Also, by such ordeals of helplessness and shame, we taught the hunting animals to some extent to keep out of our territory. And then it was funny. It was a great game. And so Lop-Ear and I had chased Saber-Tooth across three miles of forest. Toward the last he put his tail between his legs and fled from our gibing like a beaten cur. We did our best to keep up with him; but when we reached the edge of the forest he was no more than a streak in the distance.
