They were riding horses, and it was clear that but for his little stratagem he must soon have been overtaken. What should be his course now? He could not reckon on their riding much farther along the main road, for they would naturally enquire of anyone they might meet if a tradesman had been seen riding a mule that way, and in the course of a few miles, allowing for their greater speed, they must suspect that their quarry had turned to one side or the other. Obviously he must lose no time. Retracing his steps, he led the mule from the muddy river-bed, remounted, and rode along the tow-path in the hope of soon discovering a road that would lead in the direction of Medina. In a few minutes he came to a rough and narrow cart-track between two fields on his left hand. It must lead somewhere, and, being anxious at any rate to put as much ground as possible between himself and his pursuers, Jack wheeled his mule to the left and rode along the rough track at a canter. He found that it led into a somewhat wider road, crossing it at an obtuse angle. The ground was much cut up by cart-wheels, and the mule laboured heavily on the soft swampy ground. Jack eased the pace, hoping that the start he had obtained would enable him to keep well ahead of his pursuers, even if they soon discovered their mistake and had the luck to track him. By and by he came to a considerable ascent, up which he was fain to allow the animal to walk, and on reaching the summit he found the poor beast so breathless that he dismounted and walked slowly on, leading the mule. Turning after a while in the direction from which he had come, he caught a glimpse, in the far distance, of a group of riders coming towards him. It was impossible to distinguish their figures, much less their features. Delay was dangerous; so without hesitation Jack sprang again on the mule’s back and set off once more towards Medina. For a time he was hidden from the riders by rows of stunted trees that lined the road. Then the road took a sharp curve to the right, and before him he saw a long hill, sloping gradually down for nearly a mile towards what appeared to be a plantation. He urged the mule now to its top speed, noting with some anxiety that the animal was breathing with difficulty, and showing other only too manifest signs of fatigue. Before he had reached the foot of the hill it was patently flagging, and when, having passed that point, another upward ascent began, the mule staggered once or twice, recovered itself, staggered again, and, finally, just as Jack came abreast of a low farmhouse that lay back some sixty yards from the road, it dropped on its knees, its rider barely escaping being thrown on his head upon the road.
