In the valley or ravine through which they had just ridden there was no stream, and the only thing which could be done was to look for one further ahead, since they had passed the last house fully three miles behind.

"It's no use crying about it," said Bob, with an assumption of cheerfulness he was far from feeling, "for here we are, and the sooner we mend matters the sooner we shall be riding on again."

"But what can we do?" asked Ralph, feeling thoroughly discouraged at this accident, which, however quickly it might be repaired, would give the thieves a chance of making good their escape. "Even if we had a whole ocean of water, you haven't got any oil after the axle is cool, nor even a wrench with which to take the wheel off."

"One of us must walk on ahead until he comes to some house, where oil and a wrench can be borrowed. Bob must drive his horses on at a walk, and halt at the first water he sees. It's an unlucky accident for us, and it seems strange that it should have happened just when it did."

"It isn't so very strange," said Bob, as he started his team along at a walk, "and, as usual, it's all my fault. When we moved the other day, we left our oil behind in the stable, and I knew the wagon needed oiling when I got down to Kenniston's. I was just going to do it when you drove up, and then, like an idiot, I forgot it."

It would do no good to discuss the causes of the accident after it had occurred. The only question was as to how the damage could be repaired, and, after that was decided, to set about doing it at once.

"I will go on ahead for the oil," said Ralph, starting out at a run as he spoke, and in few moments he was lost to view, as he disappeared behind the trees, where the road made a decided curve.

Bob and George walked, while the horses dragged the carriage with its one useless wheel, and in this fashion the boys, who a few moments before had believed that in two hours they would have overtaken the thieves and recovered the property, continued on their journey, as sad and dispirited as before they had been happy and confident.

"If this hadn't happened," said Bob, bitterly, "we should have caught the men before noon; but now it is an open question as to whether they won't get away."

"It will be strange if they don't escape," and George's voice sounded no more cheerful than did Bob's; "for even if they were not sure who their neighbors were last night, they must have been suspicious, and will do all they can to throw us off the scent. But there," he added, with a shrug of the shoulder indicative of resolution; "what's the use of mourning over what can't be helped? All we can say or do won't change matters, and we might as well look cheerful as cry."
