Charlie was looking worried when Dick awoke on the morning of the third day, and it wasnât hard to tell why. There was a bumping sound mixed widi the other noises of the tractor, and a faint jarring mixed with the feel of its motion. Charlie was going slower.
Dick started to take the controls, but the old man pushed him away. âNo, Iâd better keep her. Had the same thing happen before. Might just keep going till we hit Twilight, and might pop off any minute. If she goes, weâd better be set to work like beavers.â
âWhat is it?â Dick asked. âOne of the wheels the tracks run on?â
The old man looked at him with suddenly renewed respect. âThatâs itâgot a gear missing, must have broke off back there in the last bad spot. If it was just the one gear tooth, itâll be rough, but weâll keep going. And if itâs a weakened wheel, and other teeth goâwell, you better do a little praying. It sure isnât any fun trying to weld them things back.â
The next hour was one of worry, but the gear seemed to be holding up, if not exactly smoothly. Charlie had just begun to relax when there was a wrenching, and the tractor suddenly spun around, one track frozen and the other twisting the whole machine around.
The old man cut power and applied the brake to the other track almost at once, bringing it to a halt. For a second he sat there quietly. Then he reached out and picked up his suit.
âWe re going to have to look for the pieces, I betcha,â he said sourly. âThe way that went, it probably sprayed itself in six hunks. And if thereâs one thing Iâd hate worsen having to weld on teeth, itâs having to build up and cut out a new wheel from scrap.â
They climbed down and inspected the machine. Charlie was right. The gear had broken completely, and was missing. It had left only the bearing on which it turned.
âCould be quite a ways back,â Charlie said. âWhen they pop out, sometimes the momentum of the track holds it up for a while. Felt like that this time.â
They began searching, while Johnny drew closer to the tractor and seemed to watch them unhappily. By the time they had gone back a hundred feet, Dick began to abandon hope, but Charlie kept on, looking from side to side. Dick shook his head and followed the older manâs example.
Suddenly Charlie moved forward quickly, and scooped up something from the hot ground. It was almost half of a gear wheel, broken across the bearing. âYep. See. Right here is where that tooth broke offâweakened the gear at the same time. Well, if we find the rest, we may get it fixed.â Dick went on searching, and it was his turn Almost straight ahead of him lay the other part, driven into the ground.
