But even the huge monarch of the city had her constant and pressing duty of maternity. A dozen times the size of her largest loyal servant, she was no less bound by the unwritten but imperative laws of the city than they. From the time of waking to the time of rest, she was ordained to be the queen-mother in the strictest and most literal sense of the word, for at intervals to be measured only in terms of minutes she brought forth a single egg, perhaps three inches in length, which was instantly seized by one of her eager attendants and carried in haste to the municipal nursery.

There it was placed in a tiny cell a foot or more in length until a sac-shaped grub appeared, all soft, white body save for a tiny mouth. Then the nurses took it in charge and fed it with curious, tender gestures until it had waxed large and fat and slept the sleep of metamorphosis. When it emerged from its rudimentary cocoon it took the places of its nurses until its soft skin had hardened into the horny armor of the workers and soldiers, and then it joined the throng of workers that poured out from the city at dawn to forage for food, to bring back its finds and to share with the warriors and the nurses, the drone males and the young queens, and all the other members of its communities, their duties in the city itself. That was the life of the social insect, absolute devotion to the cause of its city, utter abnegation of self-interest for the sake of its fellows—and death at their hands when their usefulness was past. They neither knew nor expected more or less.

It is a strange instinct that prompts these creatures to devote their lives to their city, taking no smallest thought for their individual good, without even the call of maternity or sex to guide them. Only the queen knows motherhood. The others know nothing but toil, for purposes they do not understand, and to an end of which they cannot dream. At intervals all over the world of Burl's time these ant-cities rose above the surrounding ground, some small and barely begun, and others ancient colonies which were truly the continuation of cities first built when the ants were insects to be crushed beneath the feet of men. These ancient strongholds towered two, three, and even four hundred feet above the plains, and their inhabitants would have had to be numbered in millions if not billions.

Not all the earth was subject to the ants, however. Bees and wasps and more deadly creatures crawled over and flew above its surface. The bees were four feet and more in length. And slender-waisted wasps darted here and there, preying upon the colossal crickets that sang deep bass music to their mates—and the length of the crickets was the length of a man, and more.

Spiders with bloated bellies waited, motionless, in their snares, whose threads were the size of small cables, waiting for some luckless giant insect to be entangled in the gummy traps. And butterflies fluttered over the festering plains of this new world, tremendous creatures whose wings could only be measured in terms of yards.

An outcropping of rock jutted up abruptly from a fungus-covered plain. Shelf-fungi and strangely colored molds stained the stone until the shining quartz was hidden almost completely from view, but the whole glistened like tinted crystal from the dank wetness of the night. Little wisps of vapor curled away from the slopes as the moisture was taken up by the already moisture-laden air.

Seen from a distance, the outcropping of rock looked innocent and still, but a nearer view showed many things.

Here a hunting wasp had come upon a gray worm, and was methodically inserting its sting into each of the twelve segments of the faintly writhing creature. Presently the worm would be completely paralyzed, and would be carried to the burrow of the wasp, where an egg would be laid upon it, from which a tiny maggot would presently hatch. Then weeks of agony for the great gray worm, conscious, but unable to move, while the maggot fed upon its living flesh—

There the tiny spider, youngest of hatchlings, barely four inches across, stealthily stalked some other still tinier mite, the little, many-legged larva of the oil-beetle, known as the bee-louse. The almost infinitely small bee-louse was barely two inches long, and could easily hide in the thick fur of a great bumblebee.

This one small creature would never fulfill its destiny, however. The hatchling spider sprang—it was a combat of midgets which was soon over. When the spider had grown and was feared as a huge, black-bellied tarantula, it would slay monster crickets with the same ease and the same implacable ferocity.
