VI

His fevered eyes studied the vision plate. Pluto—since they had been pointing toward it, must be ahead. He held his hand over a button, and cross hairs appeared on the plate. At the junction of the hairs was nothing.

But he found a grayish blob larger than the others at the edge of the plate. Experimentally, he turned in the rockets and headed for it. It moved steadily to the right, so it must be the planet.

Several hours later he was circling Pluto, searching grimly for the landmarks. A coating of frozen air covered everything—Pluto's last snow. Luck was with him, for he had only half-circled the globe when he saw what he wanted. There was no mistaking the scene. His pulse leaped as he dived inexpertly down.

Down past the snow sheathed peaks, into a great snow filled valley. He leveled off over the plain and brought his vessel to the surface in the thin solar illumination. He didn't know that landing on an airless planet was a feat for an expert pilot; neither did he realize that he was landing with blazing rocket jets on frozen air. But the luck of beginners was with him. He plowed a mile through the icy crust and jolted to a stop.

In his wake vast masses of freshly vaporized air clouded the valley and started to freeze again. Barnard's eyebrows lifted when he looked out.

"A snowstorm," he marveled.

He glared at the mountain wall a hundred yards distant. There was a structure there, of human origin. A squat building from around which the snow had been cleared.

George Melvin's space suit was too short for him, but he worked into it. Over the boots he fitted snow shoes. There was no sign of life from the shack, so he went out the lock and started trudging the hundred yards.
