'The Indians may be back in a few minutes, papa. Your horse is dead, but there is one of the Indians' standing by his dead master. Let us catch him and shift the saddle.' The animal, when they approached it, made no move to take flight, and they saw that his master's foot, as he fell, had become entangled in the lasso, and the well-trained beast had stood without moving. In three minutes the saddles were transferred, and the party again ready for fight or flight. 'What next, papa?' 'We turned to the right, and rather towards home, when we started; so the Indian halting-place is to the south-east of us, is it not?' 'Yes, papa; as near as may be,' Charley said, making out the points with some difficulty on the pocket-compass, one of which they each carried, as the danger of being lost upon the pathless Pampas is very great. 'We had ridden about two miles when I got my fall, so we are a mile to the west of their camp. We will ride now a couple of miles due north. The Indians are sure to send out a scout to see whether we have returned home, and our track will lead them to believe that we have. It is dusk now. We shall get three hours' rest before we have to move.' It was perfectly dark before they reached their halting-place. The saddles were again loosened, a little Indian corn, moistened with water, given to the horses, and another slight meal taken by themselves. The boys, by Mr. Hardy's orders, though sorely against their own wishes, then lay down to get a couple of hours' sleep; while Mr. Hardy went back about a hundred yards along the trail they had made on coming, and then turned aside and sat down at a distance of a few yards to watch, in case any Indian should have followed up their trail. Here he sat for over two hours, and then returned to the boys. Charley he found fast asleep. The pain of Hubert's wound had kept him awake. Mr. Hardy poured some water over the bandage, and then, waking Charley, gave them instructions as to the part they were to play. Both of them felt rather uncomfortable when they heard that they were to be separated from their father. They raised no objections, however, and promised to obey his instructions to the letter. They then mounted their horses,--Hubert having to be lifted up, for his leg was now very stiff and sore,--and then began to retrace their steps, keeping a hundred yards or so to the west of the track by which they had come. They rode in single file, and they had taken the precaution of fastening a piece of tape round their horses' nostrils and mouth, to prevent their snorting should they approach any of their own species. The night was dark, but the stars shone out clear and bright. At starting, Mr. Hardy had opened his watch, and had felt by the hands that it was ten o'clock. After some time he felt again. It was just half an hour from the time of their starting. 'Now, boys, we are somewhere close to the place of your fight. In another ten minutes we must separate.'
