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 antennae 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 antennae, 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.
Coming slowly down the slanting earth was a long, narrow file of living animals. For a time the file seemed to be but one creature, but Burl's keen eyes soon saw that there were many. They were caterpillars, each one perhaps ten feet long, each with a tiny black head armed with sharp jaws, and with dull-red fur upon their backs. The rear of the procession was lost in the mist of the low-hanging cloud-banks that covered the mountainside some two thousand feet above the plateau, but the foremost was no more than three hundred yards away.
Slowly and solemnly the procession came on, the black head of the second touching the rear of the first, and the head of the third touching the rear of the second. In faultless alignment, without intervals, they moved steadily down the slanting side of the mountain.
Save the first, they seemed absorbed in maintaining their perfect formation, but the leader constantly rose upon his hinder half and waved the fore part of his body in the air, first to the right and then to the left, as if searching out the path he would follow.
The tribefolk watched in amazement mingled with terror. Only Burl was calm. He had never seen a slug that meant danger to man, and he reasoned that these were at any rate moving slowly so that they could be distanced by the fleeter-footed human beings, but he also meant to be cautious.
The slow march kept on. The rear of the procession of caterpillars emerged from the cloud-bank, and Burl saw that a shining white line was left behind them. No less than eighty great caterpillars clad in white and dingy red were solemnly moving down the mountainside, leaving a path of shining silk behind them. Head to tail, in single file, they had no eyes or ears for anything but their procession.
The leader reached the plateau, and turned. He came to the cluster of giant cabbages, and ignored them. He came to a thicket of mushrooms, and passed through it, followed by his devoted band. Then he came to an open space where the earth was soft and sandy, where sandstone had weathered and made a great heap of easily moved earth.
The leading caterpillar halted, and began to burrow experimentally in the ground. The result pleased him, and some signal seemed to pass along the eight-hundred-foot line of creatures. The leader began to dig with feet and jaws, working furiously to cover himself completely with the soft earth. Those immediately behind him abandoned their formation, and pressed forward in haste. Those still farther back moved more hurriedly.
All, when they reached the spot selected by the leader, abandoned any attempt to keep to their line, and hastened to find an unoccupied spot in the open space in which to bury themselves.
For perhaps half an hour the clearing was the scene of intense activity, incredible activity. Huge, ten-foot bodies burrowed desperately in the whitish earth, digging frantically to cover themselves.
After the half-hour, however, the last of the caterpillars had vanished.
Only an occasional movement of the earth from the struggle of a buried creature to bury itself still deeper, and the freshly turned surface showed that beneath the clearing on the plateau eighty great slugs were preparing themselves for the sleep of metamorphosis. The piled-up earth and the broad, white band of silk, leading back up the hillside until it became lost in the clouds, alone remained to tell of the visitation.
The tribesmen had watched in amazement. They had never seen these creatures before, but they knew, of course, why they had entombed themselves. Had they known what the scientists of thirty thousand years before had written in weighty and dull books, they would have deduced from the appearance of the processionary caterpillars--or pine-caterpillars--that somewhere above the banks of clouds there were growing trees and sunlight, that a moon shone down, and stars twinkled from the blue vault of a cloudless sky.
But the tribesmen did not know. They only knew that there, beneath the soft earth, was a mighty store of food for them when they cared to dig for it, that their provisions for many months were secure, and that Burl, their leader, was a great and mighty man for having led them to this land of safety and plenty.
Burl read their emotions in their eyes, but better than their amazement and wonderment was a glance that had nothing whatever to do with his leadership of the tribe. And then Burl rose, and took the two snowy-white velvet cloaks from the wings of the white butterfly. One of them he flung about his own shoulders, and the other he flung about Saya. And then those two stood up before the wide-eyed tribesmen, and Burl spoke:
"This is my mate, and my food is her food, and her wrath is my wrath. My burrow is her burrow, and her sorrow, my sorrow.
"Men whom I have led to this land of plenty, hear me. As ye obey my words, see to it that the words of Saya are obeyed likewise, for my spear will loose the life from any man who angers her. Know that as I am great beyond all other men, so Saya is great beyond all other women, for I say it, and it is so."
And he drew Saya toward him, trembling slightly, and put his arm about her waist before all the tribe, and the tribesmen muttered in acquiescent whispers that what Burl said was true, as they had already known.
Then, while the pink-skinned men feasted on the meat Burl had provided for them, he and Saya went toward the burrow he had made ready. It was not like the other burrows, being set apart from them, and its entrance was bordered on either side by mushrooms as black as night. All about the entrance the black mushrooms clustered, a strange species that grew large and scattered its spores abroad and then of its own accord melted into an inky liquid that flowed away, sinking slowly into the ground.
In a little hollow below the opening of the burrow an inky pool had gathered, which reflected the gray clouds above and the shapes of the mushrooms that overhung its edges.
Burl and Saya made their way toward the burrow in silence, a picturesque couple against the black background of the sable mushrooms and the earth made dark by the inky liquid. Both of their figures were swathed in cloaks of unsmirched whiteness and wondrous softness, and bound to Burl's forehead were the feathery, lacelike antenna of a great moth, making flowing plumes of purest gold. His spear seemed cast from bronze, and he was a proud figure as he led Saya past the black pool and to the doorway of their home.
They sat there, watching, while the darkness came on and the moths and fireflies emerged to dance in the night, and listened when the rain began its slow, deliberate dripping from the heavy clouds above.
Presently a gentle rumbling began--the accumulation of the rain from all the mountainside forming a torrent that would pour in a six-hundred-foot drop to the river far below.
The sound of the rushing water grew louder, and was echoed back from the cliffs on the other side of the valley. The fireflies danced like fairy lights in the chasm, and all the creatures of the night winged their way aloft to join in the ecstasy of life and love.
And then, when darkness was complete, and only the fitful gleams of the huge fireflies were reflected from the still surface of the black pool beneath their feet, Burl reached out his hand to Saya, sitting beside him in the darkness. She yielded shyly, and her soft, warm hand found his in the obscurity. And Burl bent over and kissed her on the lips.
