Jack, not without being fearful of the consequences of his taking one hand from the controlling devices, did so. Luckily, as we know, the aeroplane was equipped with the latest stability devices, making her comparatively steady compared to the older fashioned craft of the air. Jack’s maneuver, therefore, was not so risky as might have been thought. While the aeroplane bucked and plunged its way through the storm Lieut. Sancho administered stimulants to Lieut. Diaz, who presently began to recover from his spell of air sickness almost as rapidly as he had been “taken down” with it. It is a peculiarity of such seizures, in fact, that they are not of long duration. Some authorities have held that there are poisoned strata in the air which cause the sickness and on emerging from them the victim becomes well again. However that may be, Lieut. Diaz was soon himself, and Jack was relieved at the wheel by Lieut. Sancho. “How far do you imagine we have been driven?” he asked as the officer took the wheel. “That is impossible to say, _amigo_ Jack. I directed you while you were in control of the ship so that as far as possible we should maneuver in circles. Judging by that, we ought not to be much more than fifty miles or so out of our way.” This was cheering news to Jack, who had begun to imagine that they had been driven half way to the Gulf of Mexico at least. As this would have meant a lot of delay in rejoining his comrades, he was naturally worried. For an hour or so more they swung in circles above the storm, and then the furious gale began to lessen. As the wind fell the sand “fog” below began to melt away just as if it had actually been mist. Its dissolving brought a view of a stretch of country not unlike that in which the Rangers had been camped when Jack had last seen them. Below them shone the river between its precipitous banks, and on one side of it Jack could see a small, rough–looking settlement. On the outskirts was a low red building, the shape and form of which at once showed it to be a schoolhouse, even if the Stars and Stripes had not been floating on a pole before the door. The aeroplane was still hovering in the air above the little settlement when the schoolhouse door opened and out rushed teacher and pupils in evident excitement. They gazed upward at the winged man–bird in a state of the greatest wonderment. Suddenly from across the river came a perfect tempest of shots and yells. Looking down, Jack saw that a body of horsemen was galloping for dear life toward the ford at the river. Close behind them came some more mounted men, although the latter were dressed in uniforms, suggesting that they were regulars. Evidently they were in pursuit of the ragged–looking Mestizos who were making for the ford. On they came at a furious gallop. Gazing from above, Lieut. Sancho announced that the band being pursued was a band of rebels, while the men in pursuit were part of the regular cavalry of the Mexican government.
