The tribe had been upon the plateau for nearly a week when Burl found that stirrings and strugglings were going on within the huge cocoon he had laid close beside the burrow he had chosen for his own. He cast aside all other work, and waited patiently for the thing he knew was about to happen. He squatted on his haunches beside the huge, oblong cylinder, his spear in his hand, waiting patiently. From time to time he nibbled at a bit of edible mushroom.
Burl had acquired many new traits, among which a little foresight was most prominent, but he had never conquered the habit of feeling hungry at any and every time that food was near at hand. He had to wait. He had food. Therefore, he ate.
The sound of scrapings came from the closed cocoon, caked upon its outer side with dirt and mold. The scraping and scratching continued, and presently a tiny hole showed, which rapidly enlarged. Tiny jaws and a dry, glazed skin became visible, the skin looking as if it had been varnished with many coats of brown shellac. Then a malformed head forced its way through and stopped.
All motion ceased for a matter of perhaps half an hour, and then the strange, blind head seemed to become distended, to be swelling. A crack appeared along its upper part, which lengthened and grew wide. And then a second head appeared from within the first.
This head was soft and downy, and a slender proboscis was coiled beneath its lower edge like the trunk of one of the elephants that had been extinct for many thousand years. Soft scales and fine hairs alternated to cover it, and two immense, many-faceted eyes gazed mildly at the world on which it was looking for the first time. The color of the whole was purest milky-white.
Slowly and painfully, assisting itself by slender, colorless legs that seemed strangely feeble and trembling, a butterfly crawled from the cocoon. Its wings were folded and lifeless, without substance or color, but the body was a perfect white. The butterfly moved a little distance from its cocoon and slowly unfurled its wings. With the action, life seemed to be pumped into them from some hidden spring in the insect's body. The slender antennæ spread out and wavered gently in the warm air. The wings were becoming broad expanses of snowy velvet.
A trace of eagerness seemed to come into the butterfly's actions. Somewhere there in the valley sweet food and joyous companions awaited it. Fluttering above the fungoids of the hillsides, surely there was a mate with whom the joys of love were to be shared, surely upon those gigantic patches of green, half hidden in the haze, there would be laid tiny golden eggs that in time would hatch into small, fat grubs.
Strength came to the butterfly's limbs. Its wings were spread and closed with a new assurance. It spread them once more, and raised them to make the first flight of this new existence in a marvelous world, full of delights and adventures—Burl struck home with his spear.
The delicate limbs struggled in agony, the wings fluttered helplessly, and in a little while the butterfly lay still upon the fungus-carpeted earth, and Burl leaned over to strip away the great wings of snow-white velvet, to sever the long and slender antennæ, and then to call his tribesmen and bid them share in the food he had for them.
And there was a feast that afternoon. The tribesmen sat about the white carcass, cracking open the delicate limbs for the meat within them, and Burl made sure that Saya secured the choicest bits. The tribesmen were happy. Then one of the children of the tribe stretched a hand aloft and pointed up the mountainside.
