Then there was the fort. In case he found the lady and restored her property in time he might be able to reach the fort by evening. He must take that into consideration also.

With alacrity he arose and went about his preparations, soon having his small baggage in array. His own toilet came next. A bath and fresh clothing; then, clean shaven and ready, all but his coat, he flung himself upon his bed for ten minutes of absolute relaxation, after which he felt himself quite fit for the expedition. Springing up he put on coat and hat, gathered up with reverent touch the bits of things he had found, locked his cabin and went out to Billy, a lump of sugar in his hand.

"Billy, old fellow, we're under orders to march again," he said apologetically, and Billy answered with a neigh of pleasure, submitting to the saddle as though he were quite ready for anything required of him.

"Now, Father," said the missionary with his upward look, "show us the way."

So, taking the direction from the hoof print in the sand, Billy and his master sped away once more into the westering light of the desert towards the long black shadowed entrance of the canyon.
