ball-tipped rods. The gestures were almost too swift to follow.

He stared at the central figure, and it gazed back with its withdrawn, pupilless, rust-red eyes. Its head was, as Villa had told them, the shape of a watermelon, with the eyes wide-set on either side of a gently agitating orifice that was probably a nostril. The mouth, very human in shape, with full lips the color of the eyeballs, was quite low in the face. There was a rough growth of gray-black hair on the crown of the big head and a fuzz of it, less dark, on the face itself. There seemed to be no ears.

Its body, long and thick, was dwarfed by the tremendous arms. Its feet were large, toeless, and flat; its legs joined smoothly to the trunk about halfway up. It wore clothing of a sort, which surprised Calvin Full, perhaps more than anything else about the being. There was a kind of short sleeveless jacket of amber color caught at the front by a long silver bar, and a white skirt worn under the legs, reaching from just below the hip joints to the bottom of the torso.

Its companions were almost identical with it, except for clothing of different hues and varying cut.

The thing in the middle now opened its mouth and made a noise that reminded Full of an off-key clarinet.

"Gpwk?" it said, with a rising inflection. "Hummr gpwk?"

Abruptly it came forward, its motions flowing and yet a bit jerky, its long legs carrying it rhythmically, but with a hint of gawkiness; Calvin thought of a galloping giraffe he and his wife had seen in a travelogue some nights before. It towered over them, bending at the hip joints.

"Steady, dear," he said.

"I'm all right," his wife said shakily, seeming just on the verge of screaming.

"Wish I could say the same," said Adam Pierce, the Negro boy. "What a specimen!"

"Look like anything to you?" asked Watkins.

"Hell, no. Unless it's something from Mars."

"Maybe we're on Mars," said Watkins conversationally, but no one responded.

It's as sensible a suggestion as the East Indian one, thought Calvin. He had not the slightest idea where they were, and he saw no sense in worrying over it until they had more information to build theories on.

The beast making no further move, his wife at last leaned toward him and said in his ear, "Calvin, can you tell what—I mean whether it's male or female?"

He studied it carefully. He couldn't even make a guess. He shook his head.

Then it reached forward its stick and thrust it directly at Calvin's face. He backed off, startled and somewhat frightened. At once the thing touched Mrs. Full with the ivory ball, as if to separate her from the knot of men.

She cried out in pain, and Calvin leaped forward; he had a flash of the great paw coming at him with the prod aimed for his face again. It touched his forehead, he felt an intense shock, and then he was powerless to move.

His mind screamed, he could feel tiny muscles try sluggishly to crawl deep under his skin, but he was paralyzed where he stood in an attitude of charging; he knew his face must be twisted in horror and rage, but he could feel nothing. Only his mind and eyesight seemed wholly clear.

He saw his wife taken off, stumbling unwillingly and looking back at him over her shoulder. Watkins said, (Calvin could hear plainly, he found), "Watch it, he's falling!" Then the paralysis left him and he slumped as though all his bones had been extracted. Someone caught him under the arms, holding him up. He tried to move, but aside from rolling his eyes and lolling his tongue out, he was helpless.

Summersby, behind him, said, "Are his eyes open?"

"Yeah." Watkin's face appeared before him. "Poor guy looks half dead."

Calvin blinked and made a try at speech, but nothing came out but a flop-tongued drooling sound.

The two creatures remaining near them squatted down and observed them, making fragmentary noises to each other. Watkins started to walk after the third, which had escorted Mrs. Full across the wide room and was on the point of making her get onto a low platform on which were a number of structures of purple tubing and crimson boxes and varicolored small contrivances. One of the pair flicked its goad across his path.

Villa said, "Come back, you foolish, do you think you can take that stick?" He sounded furious, probably because he was afraid of the beasts becoming enraged.

Calvin made a wracking effort to say, "Let him go," for surely they couldn't stand callously by and see his wife undergo the Lord knew what tortures; but the sound he made was unintelligible.

Watkins said, "Blast it, Viva, we don't know what the thing might do to her."

"Come on back," said Summersby. "Do you want to get this?" He hefted the limp Full.

Calvin writhed and managed to move his hands up and down.

"He's gaining," said Watkins, coming back.

"Those rods pack a wallop," said Adam. "What sort of power can they have in 'em? Seems to me they're away beyond our science."

"They're not hitched to batteries," said Watkins. "Say, look at all this machinery. If these animals built it, they're a pretty advanced race."

Mrs. Full was seated now on a large thing like a chrome-and-rubber chair, one of those modern abominations which she and Calvin so cordially detested. He could not see her face. The twelve-foot brute was moving its fingers before her, evidently telling her to do something. Calvin heard her say plaintively, "But what is it?"

Summersby hoisted him up and about then feeling began to come back to him with a sharp, unpleasant tingling of the skin. He said, "Help her!" quite distinctly.

"Nothing's happening to her," said Watkins. "Take it easy."

Mrs. Full was apparently pulling levers and moving blocks of vividly colored material back and forth on rods; like an abacus, thought her husband.

Suddenly one of the other pair of creatures gave a cry, "Brrm hmmr!" and pointed to the left. From a muddle of gear rose a small airship, orange, with a nose like a spaceship and streamlined fins, and a square box on its tail. It made no noise, but rose straight toward the ceiling, moving slowly, jerkily.

His wife had her back to it. He heard her give an exasperated, bewildered cry. "What on earth ... what are you doing?" She spoke to the creature as if it understood. "I don't see why you—"

Calvin pushed free of Summersby. He could stand now, shakily. The beast indicated a blue block on a vertical bar; Mrs. Full moved it down, the airship halted and began to sail toward them. "Do you see the toy ship?" called Calvin. "You're flying the ship!"

"Oh, my," she said helplessly. "What shall I do now?"

"This is crazy," said Watkins. "Absolutely crazy."

"Go on moving things," Calvin called to his wife. "Experiment. It wants you to fly it." It occurred to him that this was too obvious to bother stating. He must be distracted by weakness. He rubbed his tingling arms and hands, hoping she wouldn't crash the ship. Villa and Adam Pierce were calling encouragement to her as the orange thing drifted up and down and sideways.

Now the twelve-foot being gestured briefly at a portion of the apparatus, Mrs. Full caught his meaning and moved something, and the ship tilted and flew along the wall without touching it. All three of the creatures uttered sounds that might be taken for words of pleasure.

"Good girl!" yelled Watkins. "Keep it up!"

She turned to them and Calvin saw she was smiling. "There's really nothing to it," she said. The airship bumped into the wall and fell. The animal above her squawked and pressed down a lever, which evidently sent out a beam or impulse that caught the ship in midair and held it suspended. Then it grasped Mrs. Full and carried her, flailing her limbs, over to the corner.

Calvin started forward, apprehensive.

"Hold it, Cal, you don't want another shock." Watkins took his arm.

The creature kicked aside a mound of small gadgets,
