rocks from cutting the strips of hide.

"Here you come!" he cried to Jack, and he began to haul, taking care to
keep his own head near his torch, which was stuck upright. Mark had
spoken truly when he said he possessed much more than his usual
strength. Any one who has tried to haul up a person with a rope from a
hole, and with no pulleys to adjust the strain of the cable, knows what
a task it is. But to Mark, on the moon, it was comparatively easy.

Hand over hand he pulled on the hide rope until, with a final heave, he

mouth of the crater, and the thick fur coat Jack wore had prevented the
sharp rocks from injuring him. In another moment he stood beside Mark,
a trifle weak and shaky from his experience, but otherwise unhurt.

"How did you happen to go down there?" asked Mark.

"Not from choice, I assure you," answered Jack. "I couldn't see the
crater when I jumped, as it was hidden by some rocks, and I was into it
before I knew it. But don't stand talking here. Put on my coat. I don't
need it. I'm warm."

"I will not. I'm not a bit cold. But we may as well get back to the
projectile, for they'll be worrying about us." Thereupon Mark broke

In a short time the two lads were back at the _Annihilator_, where
they found Professors Roumann and Henderson getting a bit anxious about
