and dogs were running here and there, playing with the many infants, or else fighting with each other. Women sat and sewed or hung up washing or dried dishes or nursed babies. Hens clucked defiantly from behind the bars of their coops, scattered everywhere. On the port side there was even a pigpen holding about thirty of the tiny rabbit-eared porcines.

Green followed Amra to a place where an awning had been stretched to make a roof.

"Isn't this nice?" she said. "It has sides which we can pull down when it rains or when we want privacy, as I suppose we will, you being so funny in some ways."

"Oh, it's delightful," he hastened to assure her. "I see you even have some feather mattresses. And a cookstove."

He looked around. "But where are the fish tanks? I thought Miran was going to bolt them to the deck?"

"Oh, no, he said that they were too valuable to expose to gunfire if we encountered pirates. So he had the deck cut open wide enough to lower the tanks inside the hold. Then the deck planking was replaced. Most of these people here would be sleeping below if it weren't for the tanks. But there's no room now."

Green decided to take a look around. He liked to have a thorough knowledge of his immediate environment so that he would know how to behave if an emergency arose.

The windroller itself was about two hundred feet long. Its beam was about thirty-four feet. The hull was boat-shaped, and the narrow keel rested on fourteen axles. Twenty-eight enormous solid rubber-tired wheels turned at the ends of these axles. Thick ropes of the tough rubber-like substance were tied to the ends of the axles and to the tops of the hull itself. These were to hold the body steady and keep it from going over when the 'roller reeled under too strong a side wind and also to provide some resiliency when the 'roller was making a turn. Being aboard at such times was almost like being on a water-sailing ship. As the front pair of wheels--the steering wheels--turned and the longitudinal axis of the craft slowly changed direction, the body of the vessel, thrust by the shifting impact of the winds, also tilted. Not too far, never as far as a boat in similar case, but enough to give one an uneasy feeling. The cables on the opposing side would stretch to a degree and then would stop the sidewise motion of the keel and there would be a slight and slow roll to the other direction. Then a shorter and slower motion back again. It was enough to make a novice green. 'Roller sickness wasn't uncommon
