approached more closely he observed that they were all dotted here and there with round holes about four feet in diameter.
He arrived within fifty feet of the nearest mound without noting any signs of animate life, and, concluding that it must be deserted, stepped boldly forward. Then, without the slightest hint of warning, something darted out suddenly and ran toward him on its six horny legs with incredible swiftness.
The creature was about the size of a small Shetland pony, with eyes as big as dinner plates set in a head more than two feet across and surmounted by two long, jointed antennae, its jaws armed with sharp mandibles and a pair of forceps large enough to encircle two men. The entire body was covered with glistening ivory-white armor. It came at him with forceps outspread.
In a moment, Grandon found that his tork had no effect; a moment later, he found his sword equally useless. The forceps encircled him, and he was dragged into the dark hole.
Vernia stepped out of the airship and climbed the projecting bark of the tree; it had been over two hours since Grandon left, and she was worried. From a height of several hundred feet above the airship, she peered through the thick curtain of leaves and saw that this tree stood in a narrow valley. The encircling mountains were bare, but the valley itself was filled with giant trees.
She looked down to see a white, six-legged monster scuttling up the trunk, carrying a smaller, bright green creature in its forceps. It turned out on a limb just below her, to deposit its burden on one of the large leaves.
The green thing had six legs, but its plump body was oval-shaped, with the head set at the narrow end and two sharp horns protruding just above the posterior extremity. As soon as it was put down, it uncoiled a long, slender sucking tube which it inserted in the leaf.
Vernia was both mystified and frightened. She flattened out on the limb, and peered cautiously over the edge.
To her infinite terror she saw many more mounting the tree and depositing their burdens here and there until it literally swarmed with the white things and their green charges. Glancing across to the next tree, she saw that it was similarly infested, and shuddered at the thought that the monsters might soon climb to where she was concealed.
Then, she saw a number of naked, hairy men ascending the tree. Each man carried a sack slung over his shoulder and fastened in place by a strap. She noticed that there appeared to be no animosity between the men and the monsters, and concluded that the great antlike creatures must have been domesticated by these cavemen.
Her supposition was strengthened by the sight of one of the men obtaining a white, sticky substance from one of the green things, with the aid of a white one, which titillated the posterior horns of its smaller green charge, causing it to exude the material into the sack which the man carried. All the other men were engaged in the same task, going from leaf to leaf until their sacks were filled, then carrying them down the tree.
A man who moved more slowly than his fellows was nipped sharply by one of the white creatures. He gave a cry of pain and hurried his steps. Then it dawned on her that the men were the slaves and the monsters their masters!
She was reflecting on this paradox when one of the white things, which had mounted on the opposite side of the tree unobserved by her, took a notion to carry its green charge out on the limb she occupied. She rose hurriedly and ran toward the swaying tip, but the creature deposited its burden on a leaf and darted after her with amazing speed. She had only gone a few steps when the powerful forceps encircled her.
Her captor appeared able to travel on the rough tree trunk upside down or right side up with equal facility, and carried her down to the ground at a terrific rate of speed. When it
