It was warm in the round Mars ship and cage. In a few minutes, they were sailing into rapidly falling darkness. John lost all sense of direction. At last, blue lights flashed in the cold night above a dim floor of thick plant life, and their little ship slid sidewise to a stop inside a massive hillside door. They could not understand why Jake was rayed into unconsciousness and taken away, before they were sent sliding and unattended down the long corridor to their former room. There were now four of the low beds and a fresh tray of food had been prepared. They ate, and fell into drugged sleep.

Life went on quietly, back in this observation cage, nearly a week. Every morning they were questioned for an hour or more by the council of scientists through the wall screen. Hilda persuaded John to be as co-operative as possible, hoping that the old men's intentions were still kind. The questions were especially centered about details of health on earth, medicine, eugenic control, the number of sick people, and about the possibility of future colonies.

Mary and Dr. Smithson proved fascinating companions in the long idle hours, with a dramatic story to tell of their recent trip to Venus. Earth's first expedition to that world in 1978 had not yet been reported in the public press.

It was on the sixth day that they saw Jake Adams again. He came sliding in on a rolling stretcher, propelled by unseen forces, and his eyes were closed.

Mary gasped, "Look at his legs!"

John stepped quickly to the stretcher and ran his hands over Jake's body, then stood and cried. "They're warm—and alive!"

During their brief wait in the cave they had seen the old soldier stumping around on two wooden legs, supplemented by crutches. He was spry and cheerful for a man nearly seventy years old, and his hands and arms were abnormally strong. Hilda had been indignant that the army should neglect this old hero and fail to provide him with suitable artificial limbs. Her own handicap made her feel a special sympathy, and she had stopped to talk with the old fellow briefly. He told her that he had been wounded in the battle against the Japs in the Marshall Islands during 1944.

Now the old soldier lay, with a slightly flushed face, breathing quietly, and in place of the wooden pegs were two perfectly formed legs wrapped in silvery transparent leggings!

As they watched, the old man slowly awakened, but lay still as if dazed. Then an expression of alarm or amazement began to open his eyes. He moved his toes, and then lay back muttering, "No, it's just another of them nerve tricks—the way I used to feel about the weather!" But he slowly raised his head, as if fascinated. When his eyes focused on the new feet, he snapped suddenly to a sitting position and reached for his ankles.

"I can feel! I can feel—They're alive!" he screamed.
