"Well, I guess it'll be all up with us then, if we don't starve to death in the meanwhile," answered Jack. "But I'm afraid we will get out of food before the torches are exhausted. They were freshly filled before we started out after that tool, and they'll last for two weeks. So we don't have to worry about that.
"By Jinks! this is all my fault, anyhow, it seems. If I hadn't seen that item in the Martian paper about the diamonds, we never would have come here, and if I hadn't left that tool on the ground outside of the projectile we wouldn't have had to come back after it, and we wouldn't have become lost. So I guess it's up to me, as the boys say."
"Oh, nonsense!" exclaimed Mark, who, as soon as he heard his chum blaming his own actions, was ready to shoulder part of the responsibility himself. "We all wanted to come to the moon," he went on, "and, as for leaving the tool and forgetting it, I'm as much at fault as you are. Let's go to sleep, and maybe we'll feel better when we wake up."
It was a new role for Mark—to be cheerful in the face of difficulties—and Jack appreciated it. They stretched out on the hard, rocky floor of the cavern, taking care to fix their life-torches so that the fumes would dispel the poisonous gases. Then the two lads joined Andy in slumberland.
Meanwhile, as may be imagined, those aboard the projectile were very anxious about the fate of the two boys and the hunter. They could not understand what delayed them, and, though they guessed the real cause, after several hours had passed, there was nothing the two scientists could do.
They could not move the projectile until it had been repaired, and this could not be done, without the tool—at least, they did not believe so then. Nor did Mr. Henderson and the German think it would be safe to start out in search of the wanderers.
"For," said Mr. Henderson, "if we went we would easily get lost amid these peaks ourselves, and they are so much alike and in such numbers that there is no distinguishing feature about them. We had better stay here in charge of the Annihilator until the boys and Andy come back. They can't be away much longer now."
So worn out and exhausted were the boys and the hunter that they slept for several hours in the cave, and the rest did them good. They awoke in better spirits, and, after a frugal meal and a sip of the fast-dwindling water, they started off once more to locate the projectile.
"I'm a regular amateur hunter to go and lose my compass," complained old Andy. "I ought to have it fastened to me, like a baby does the rattle-box. I ought to kick myself," and he accepted all the blame for their misadventure. But the boys would not suffer him to thus accuse himself, and they insisted that they would shortly be with the two professors and Washington in the Annihilator once more.
"Well, it can't come any too soon," said Jack, "for I am beginning to feel the need of a square meal and a big drink of water."
