He now ran to his horse, which was trembling in every limb and struggling wildly to escape, soothed it by patting it, loosed its bonds, sprang into the saddle, and went off at full gallop in the direction by which he had come. He had not ridden very far before he heard, in the still night air, the repeated sound of firearms, and knew that the boys were upon the trail of the cattle. Mr. Hardy had little fear of the Indians pursuing them; he felt sure that the slaughter of the day by the new and mysterious firearms, together with the effect of the rockets, would have too much terrified and cowed them for them to think of anything but flight. He was, however, much alarmed when, after a quarter of a hour's riding, he heard a single sharp whistle at about a few hundred yards' distance. "Hurrah! papa," the boys said as he rode up to them. "They have gone by at a tremendous rush--sheep and cattle and all. We started the moment we saw your first rocket, and got up just as they rushed past, and we joined in behind and fired, and yelled till we were hoarse. I don't think they will stop again to-night." "Did you see or hear anything of the Indians, boys?" "Nothing, papa. When the first rocket burst we saw several dark figures leap up from the grass--where they had been, no doubt, scouting--and run toward the camp but that was all. What are we to do now?" "Ride on straight for home. We need not trouble about the animals; they won't stop till they are back. We must go easily, for our horses have done a very long day's work already. They have been between fifty and sixty miles. I think that we had better ride on for another hour. By that time the moon will be up, and we shall be able to see for miles across the plain. Then we will halt till daybreak--it will only be three hours--and the horses will be able to carry us in at a canter afterward." And so it was done. In an hour the moon was fairly up, and, choosing a rise whence a clear view could be obtained, the horses were allowed to feed, and Mr. Hardy and Hubert lay down to sleep, Charley taking the post of sentry, with orders to wake the others at daybreak. The day was just dawning when he aroused them. "Wake up, papa. There are some figures coming over the plain." Mr. Hardy and Hubert were on their feet in an instant. "Where, Charley?" "From the north, papa. They must have passed us in their pursuit of the cattle, and are now returning--empty-handed, anyhow; for there are only seven or eight of them, and they are driving nothing before them." By this time all three were in the saddle again. "Shall we attack them, papa?" "No, boys; we have given them quite a severe lesson enough. At the same time, we will move a little across, so that we can get a good sight of them as they pass, and make sure that they have got nothing with them." "They are coming exactly this way, papa."
