The mules, upon the reins being jerked, and boys' heels briskly applied to their ribs, moved on at a fast walk. "We shall have to stop under a tree and cut a stick presently," Hawtry said. "It will not do to get down, for I should never be able to climb up again. Mind, we must take our bearings carefully, else we shall never get back again. We have neither chart nor compass. Hallo! here comes the mules' master." They had by this time gone two or three hundred yards from the village, and, behind them, at a brisk trot, seated on a diminutive donkey, was the Spaniard. "Perhaps it's best he should come," Jack said. "There will be no fear of being lost then, and if one of us gets capsized, he can help him up again." Upon the Spaniard coming up to them, he gave a sharp shout to the mules, at the same time striking the donkey on which he rode with a stick. Instantly the mules, recognizing the signal, started into a sharp trot, the first effect of which was to tumble Hawtry from his seat into the road, Jack with difficulty saving himself by clutching wildly at the mane. "Confound it!" Hawtry exclaimed furiously, as he regained his feet, to the Spaniard. "Why didn't you say what you were going to be up to? Starting the ship ahead at full speed without notice! I believe I've broken some of my ribs. Don't you laugh too soon, Jack. It will be your turn next." The Spaniard helped Hawtry to regain his seat, and they were soon clattering along the dusty road at a brisk rate, the boys quickly getting accustomed to the pace, which, indeed, was smooth and easy. For hours they rode on, sometimes trotting, sometimes walking, taking no heed whither they were going, and enjoying the novelty of the ride, the high cactus hedges, the strange vegetation, little villages here and there, sometimes embowered in orange trees, and paying no heed to time. Presently Jack exclaimed,-- "I say, Hawtry, it must be getting late. We have been winding and turning about, and I have not an idea how far we are now from Gib. We must be through the gates by gun-fire, you know." They stopped, and by pantomime explained to the Spaniard that they wanted to get back again as soon as possible. He nodded, made a circle with his arm, and, as they understood, explained that they were making a circuit, and would arrive ere long at their starting-place. For another hour and a half they rode along, chatting gayly. "I say, Jack," Hawtry exclaimed suddenly, "why, there's the sun pretty nearly down, and here we are among the hills, in a lonelier looking place than we have come to yet. I don't believe we're anywhere near Gib. I say, old fellow, it strikes me we're getting into a beastly mess. What on earth's to be done?" They checked their mules, and looked at each other. "What can the Spaniard's game be, Hawtry? We've had a good five shillings' worth."
