Garry argued against taking nearly all of the spare supplies and leaving their friends with very little.

“You must take them,” Captain Eaton insisted. “If you do not have enough to get you to the settlement, there is no purpose in starting out at all. Now, no more arguments.”

There finally came the moment of parting, which everyone dreaded. Garry’s heart was heavy at the thought of leaving these people he had grown so fond of in such a short time. Very likely he and Patch would never see any of them again.

Garry could see that the men’s eyes were troubled and sorrowful. They didn’t seem to know just how to say farewell. Isaac and Gino gave a little nervous wave of their hands. Mr. Klecker shook hands formally. Mac gave them a warm pat on the back.

Captain Eaton walked slowly over to the air lock with the boys—slowly, as if he did not want to let them go. Garry and Patch had removed their helmets and held them in their hands. The captain had his arms around their shoulders, embracing them like a father.

“Well, don’t let’s be sissies about this,” the captain said with forced lightheartedness. “Let’s just pretend that you boys are going on a short trip and that you’ll be back in a little while. No sad words, no tears, eh?”

“That’s how we want it, Captain Eaton,” Garry answered, but his throat was so tight he could hardly speak.

“Whatever you do, don’t give up,” their older friend advised. “Take care of yourselves and don’t lose your heads if you meet a crisis. And don’t come back, whatever happens. It won’t help.”

The captain took a piece of paper from Mac and gave it to Garry. “Mac and I have plotted your course as nearly as we can from what we remember of this territory. We both had a course in lunar study at one time. Follow these landmarks closely. You will be heading straight for the mining settlement, and if, by chance, a search flier should be coming from that direction, try to catch their attention by waving. They will probably be looking for you, and your bright-colored suits will make you stand out pretty strong against the gray ground.”

Garry was studying the penciled map. “What is this gray part that you’ve shown here, Captain?”
