Jarvis was close enough, however, to hear the warning cry. He opened his mouth to answer, getting it full of red ore as a result. The ore got down in his throat, sending him into a paroxysm of choking, sneezing and growling that was lost in the noise about him.

Suddenly Steve felt himself shooting through space. He realized, in that instant, that he had left the chute. A few seconds more and he struck heavily on his feet, bounded into the air, then plunged forward head first.

The lad landed on his stomach, slipped down a conical pile of ore to the bottom, his head striking the side of the ship, doubling him up and leaving him stunned and unconscious.

Jarvis, who was not far behind him, went through very much the same experience, save that he turned a somersault when he left the chute, landing flat on his back on the pile of ore. His feet drove against the side of the ship with the force of a battering-ram, backed by the full weight of the lad's body. The effect was nearly the same as it had been in the case of Rush. Bob was stunned. He, too, lay still, after curling up against the vessel's side.

"Hey, what's that?" a voice had shouted as the boys disappeared through the hatches.

"What's what?"

"I thought I saw something besides ore go through the chute in number seven hatch."

"You're seeing things!"

"Maybe I am."

"Close number seven hatch!" shouted the second mate, and the two deck hands, after the chute had been hoisted a little above the deck, slid the heavy hatch cover into place. All the ore that was needed had gone in through that hatch. The ship was nearly loaded. All that was now required was a few car-loads at the ends to trim the ship properly, after which she would be ready to sail.
