The only hope now was a hasty repair of the refrigerator unit. Steve hustled back into the ship and made his way to the rear where the cooling machinery was located. He found Bart working there, his helmet off. Steve removed his own helmet, for apparently Bart had repaired the trouble. The customary blandness of the atmosphere had been restored.

“What happened to it?” Steve asked.

“The dynamo burned out,” Bart answered. “I just coupled in the spare one. Where have you been?”

“Out on the skin,” Steve said. “I was trying to signal Jim Dennis.”

Bart’s face went red again, and he muttered to himself.

“I didn’t think there was any chance of repairing the trouble,” Steve went on.

“I’d rather burn than take help from Jim Dennis!” Bart snapped. “Did Dennis see you?”

“He must have. He went right overhead.”

“Obviously he didn’t stop, though.”

“No, he didn’t,” Steve said frankly.
