A windowless wall had been knocked out for twenty feet. There was blue sky outside, its light almost hurtful, and a drop of many stories. A file of humans were being processed. When one of them got to the head of the file his (or her) tickler was ceremoniously unstrapped from his shoulder and welded onto a silvery cask with smoothly pointed ends. The result was something that looked—at least in the case of the Mark 6 ticklers—like a stubby silver submarine, child size. It would hum gently, lift off the floor and then fly slowly out through the big blue gap. Then the next tickler-ridden human would step forward for processing.

The second scene was in a park, the sky again blue, but big and high with an argosy of white clouds. Gusterson was lined up in a crowd of humans that stretched as far as he could see, row on irregular row. Martial music was playing. Overhead hovered a flock of little silver submarines, lined up rather more orderly in the air than the humans were on the ground. The music rose to a heart-quickening climax. The tickler nearest Gusterson gave (as if to say, “And now—who knows?”) a triple-jointed shrug that stung his memory. Then the ticklers took off straight up on their new and shining bodies. They became a flight of silver geese … of silver midges … and the humans around Gusterson lifted a ragged cheer….

That scene marked the beginning of the return of Gusterson’s mind and memory. He shuffled around for a bit, spoke vaguely to three or four people he recalled from the dream days, and then headed for home and supper—three weeks late, and as disoriented and emaciated as a bear coming out of hibernation.

Six months later Fay was having dinner with Daisy and Gusterson. The cocktails had been poured and the children were playing in the next apartment. The transparent violet walls brightened, then gloomed, as the sun dipped below the horizon.

Gusterson said, “I see where a spaceship out beyond the orbit of Mars was holed by a tickler. I wonder where the little guys are headed now?”

Fay started to give a writhing left-armed shrug, but stopped himself with a grimace.

“Maybe out of the solar system altogether,” suggested Daisy, who’d recently dyed her hair fire-engine red and was wearing red leotards.

“They got a weary trip ahead of them,” Gusterson said, “unless they work out a hyper-Einsteinian drive on the way.”

Fay grimaced again. He was still looking rather peaked. He said plaintively, “Haven’t we heard enough about ticklers for a while?”

“I guess so,” Gusterson agreed, “but I get to wondering about the little guys. They were so serious and intense about everything. I never did solve their problem, you know. I just shifted it onto other shoulders than ours. No joke intended,” he hurried to add.
