What the hell was a tumbler doing with a woman and a son?

After perhaps a minute, he stepped forward again. He tripped over a shovel, and his foot plunged into something that went squelch and swallowed the foot past the ankle. He fell forward into a heap of sand, and his foot went deeper into the sloppy wetness.

He lay there with his stinging forehead on his arms, cursing softly and crying. Finally he rolled over, pulled his foot out of the mess, and took off his shoes. They were full of mud—sticky sandy mud.

The dark world was reeling about him, and the wind was dragging at his breath. He fell back against the sand pile and let his feet sink in the mud hole and wriggled his toes. He was laughing soundlessly, and his face was wet in the wind. He couldn't think. He couldn't remember where he was and why, and he stopped caring, and after a while he felt better.

The stars were swimming over him, dancing crazily, and the mud cooled his feet, and the sand was soft behind him. He saw a rocket go up on a tail of flame from the station, and waited for the sound of its blast, but he was already asleep when it came.

It was far past midnight when he became conscious of the dog licking wetly at his ear and cheek. He pushed the animal away with a low curse and mopped at the side of his face. He stirred, and groaned. His feet were burning up! He tried to pull them toward him, but they wouldn't budge. There was something wrong with his legs.

For an instant he stared wildly around in the night. Then he remembered where he was, closed his eyes and shuddered. When he opened them again, the moon had emerged from behind a cloud, and he could see clearly the cruel trap into which he had accidentally stumbled. A pile of old boards, a careful stack of new lumber, a pick and shovel, a sand-pile, heaps of fresh-turned earth, and a concrete mixer—well, it added up.

He gripped his ankles and pulled, but his feet wouldn't budge. In sudden terror, he tried to stand up, but his ankles were clutched by the concrete too, and he fell back in the sand with a low moan. He lay still for several minutes, considering carefully.

He pulled at his left foot. It was locked in a vise. He tugged even more desperately at his right foot. It was equally immovable.

He sat up with a whimper and clawed at the rough concrete until his nails tore and his fingertips bled. The surface still felt damp, but it had hardened while he slept.
