An hour later, they heard a faint sound in the distance. Instinctively they checked their horses, and again, in the darkness of the night, the deep distant bay of a hound was heard.
"Just as I thought!" Don Estevan exclaimed. "They have got the bloodhounds, and I should think, by the sound, that they must have just reached the spot where we mounted. The hounds will be puzzled now; but the sagacity of these creatures is so great that I am by no means sure that they will be unable to follow us by the track of the horses. Now let us set spur."
For the next four or five hours they proceeded, at a steady gallop, towards the south. The country was flat; the road sandy, but even; and the cool night air was exhilarating, indeed, after the confinement in the dark and noisome dungeon at Lima. So rejoiced were the boys, with their newly-recovered freedom, that it was with difficulty they restrained themselves from bursting into shouts of joy. But they were anxious that no sounds should be heard, by the villagers of the little hamlets lying along the road. The sound of the horses' hoofs on the sandy track would scarcely arouse a sleeping man; and the fact that their tracks would be plainly visible in the sand, when daylight came, caused them no concern; as, so far, they had made no effort to deceive their pursuers.
Soon after daylight arrived they found themselves upon a stream, which ran down from the mountains and crossed the road.
"Now," Don Estevan said, "it is time to begin to throw them off our track. They will believe that the party consist solely of Indians, and our turning east will seem as if we intended to take refuge in the mountains. Let us then strike up the river for awhile, land at a spot where the horses' hoofs will be clearly visible, and then pursue a course to the southeast, taking us nearer and nearer to the hills.
"Three leagues hence is another stream. This we will enter, and they will make sure that we have pursued our former tactics--that we have followed it up, and again struck for the hills. Instead of doing this, we will follow it down for a mile or two; and quit it at some spot where the bank is firm, and will leave no marks of our footsteps. Then we will strike across the country, and regain the road some seven or eight leagues further south."
The plan appeared a capital one, and was followed out as arranged. Late in the evening, they were again in the vicinity of the southern road. In their wallets was a plentiful supply of provisions, and they had filled their water bottles at the last stream which they had crossed. Entering a grove of trees, they unsaddled their horses and allowed them to crop the foliage and shrubs; while they threw themselves down upon the soft earth, stiff and wearied with their long journey.
"We will travel by night, always," Don Estevan said. "I do not think that any suspicion, whatever, will arise that we have again struck south; but should any inquiry be made, it is as well that no one along the road shall have seen three mounted men."
For another two days they journeyed, as proposed, by night; resting by day in quiet places and, so far as they knew, without having been seen by any of the scattered population. It was in the middle of the third night, as they were cantering slowly along, that they heard the tread of a horse, at full gallop, approaching from the south.
"You had better withdraw from the road," Don Estevan said, "so that but one horseman will be met. I will stop the rider, and hear why he gallops so fast. It may be that news has preceded us, and it is as well to gather what intelligence we can."
