She must have grasped his idea without trouble, for she immediately started up the stairs. The confusion outside was growing worse than ever, and served to spur the boy on to renewed exertions.

The good woman of the house was soon pointing at the trap, and Rod quickly had it open. As he clambered out on the roof he saw to his satisfaction that it was situated on the side away from the village street. In this fashion he believed he might be able to accomplish what he had determined to attempt, at least without being interrupted by any passing Uhlan lancers.

One look in the direction of the hillside gave him cause for further delight, since he found that he could easily see the camp of the tired zouaves, who had marched many miles since sun-up in hopes of participating in the day’s battle, only to arrive when the action was all over.

Rod immediately began to wave his handkerchief wildly, though carrying out a certain program, and hoping to thus attract the attention of some sentry who may have been posted on that side of the camp.

Almost immediately he realized that this was just what had been accomplished, for he saw men running, and then a signal flag was waved in reply to his frantic appeals.

“What do you want to communicate?” was what he made out to be fashioned through the regular wigwag work of the flag.

“Village at mercy of Uhlans–come and help us at once!”

That was the message which Rod sent waving back. How glad he was at that minute he had picked up his knowledge of Signal Corps work, and could both send and receive so accurately.

That the man in the zouave camp had grasped the meaning of his dispatch Rod quickly understood, for almost immediately there was waved back an answer calculated to reassure him:

“Hold on! Relief coming! O. K.”
