"Well, maybe I will and maybe I won't."
"While you're deciding, we'll get swimming. Come along, Joggy."
Still scowling, the Butcher took a white soapy crayon from the bulging pocket in his silver shorts. Pressed into the pavement, it made a black mark. He scrawled pensively: KEEP ON THE GRASS.
He gazed at his handiwork. No, darn it, that was just what grownups wanted you to do. This grass couldn't be hurt. You couldn't pull it up or tear it off; it hurt your fingers to try. A rub with the side of the crayon removed the sign. He thought for a moment, then wrote: KEEP OFF THE GRASS.
With an untroubled countenance, he sprang up and hurried after the others.
Joggy and the older boy were swimming lazily through the air at shoulder height. In the pavement directly under each of them was a wide, saucer-shaped depression which swam along with them. The uninjes avoided the depressions. Darter was strutting on his hind legs, looking up inquiringly at his master.
"Gimme a ride, Hal, gimme a ride!" the Butcher called. The older boy ignored him. "Aw, gimme a ride, Joggy."
"Oh, all right." Joggy touched the small box attached to the front of his broad metal harness and dropped lightly to the ground. The Butcher climbed on his back. There was a moment of rocking and pitching, during which each boy accused the other of trying to upset them.
Then the Butcher got his balance and they began to swim along securely, though at a level several inches lower. Brute sprang up after his master and was invisibly rebuffed. He retired baffled, but a few minutes later, he was amusing himself by furious futile efforts to climb the hemispherical repulsor field.
Slowly the little cavalcade of boys and uninjes proceeded down the Avenue of Wisdom. Hal amused himself by stroking toward a tree. When he was about four feet from it, he was gently bounced away.
