Jardine was now conscious but had the presence of mind not to move. His head ached from the blow. Slowly he opened his eyes and saw his two attackers bending over the board. He saw that Bangs was lying on the deck facing him. Jardine winked at Bangs, who returned the signal. Then he began, carefully, methodically to send a Morse-code message to his companion via his winking eyes.

"O-N-L-Y—one—gun—between—them. You—take—big—fellow. I'll—charge—gun ..."

"Can't you figure this thing out either?" asked Mason, leaning over Loring's shoulder.

"Ah, this wagon is an old converted chemical burner. These controls are old as the sun. I've got to find the automatic pilot!"

"Try that lever over there," suggested Mason.

Loring reached over to grasp it, turning away from his prisoners.

"Bangs, get 'em!" shouted Jardine. The two men jumped to their feet and lunged at Loring and Mason. Loring dove to one side, losing the gun in the scramble, but as he fell, he reached for the acceleration control lever. He wrenched it out of its socket and brought it down on Bang's head, and the officer slid to the floor. Jardine, meanwhile, had Mason in a viselike grip, but again Loring used the lever, bringing it down hard on the neck of the freighter pilot. Jardine dropped to the deck.

"Thanks, Loring," gasped Mason. "That was close! Good thing we had on these space suits, or we'd have been finished. They couldn't grab onto the smooth plastic."

"Finished is right!" snarled Loring. "I told you to keep an eye on them! If they'd nabbed us we woulda wound up on the prison asteroid!"

"Loring," shouted Mason, "look!" He pointed a trembling finger at the thrust indicator. "We're blasting at full space speed—right for the station!"
