"The rascals have got a clever chief among them, boys. Except those half-dozen heads we see over the horses' backs, there is nothing to see of them. They know that if we go close they can pick us off with their guns and bows and arrows, without giving us a single fair shot at them. Don't go any nearer, boys; no doubt there are many of their best shots hidden in the gra.s.s."

"We could scatter the cattle with a rocket, papa."

"Yes, we could, Hubert, but we should gain nothing by it; they have got men by their horses, and would soon get the herd together again. No, we will keep that for the night. Halloo! to the right, boys, for your lives."

Not a moment too soon did Mr. Hardy perceive the danger. The chief of the Indians, expecting another attack, had ordered twenty of his best mounted men to separate themselves from the main body, and to hide themselves in a dip of the ground near the place where the first attack had taken place. They were to allow the whites to pa.s.s, and were then to follow quietly, and fall suddenly upon them.

Complete success had attended the maneuver; and it was fortunate that the party had no firearms, these having been distributed among the main body with the cattle, for they were within forty yards of Mr. Hardy before they were seen. It was, in fact, a repet.i.tion of the maneuver which had proved so successful in their attack upon the cattle.

They were not immediately in the rear of Mr. Hardy, but rather to the left. As Mr. Hardy and his sons turned to fly, a number of Indians sprang upon their feet from among the gra.s.s, and discharged a volley of guns and arrows at them. Fortunately the distance was considerable. One of their arrows, however, struck Mr. Hardy's horse in the shoulder, while another stuck in the rider's arm.

Another went through the calf of Hubert's leg, and stuck in the flap of the saddle.

There was no time for word or complaint. They buried their spurs in their horses' sides, and the gallant animals, feeling that the occasion was urgent, seemed almost to fly. In a mile they were able to break into a steady gallop, the enemy being now seventy or eighty yards behind. Mr. Hardy had already pulled the arrow from his arm, and Hubert now extracted his. As he stooped to do so his father, who had not noticed that he was wounded, saw what he was doing.

"Hurt much, old man?"

"Not much," Hubert said; but it did hurt a good deal nevertheless.

"I don't want to tire our horses any more, boys," Mr. Hardy said; "I shall try and stop those rascals with one of my revolvers."

So saying, he drew one of his pistols from his holster, and turning round in his saddle, took a steady aim and fired.

At the same instant, however, his horse trod in a hole and fell, Mr. Hardy being thrown over its head with tremendous force. The boys reined their horses hard in, and Hubert gave a loud cry as he saw his father remain stiff and unmoved on the ground. The Indians set up a wild yell of triumph.

"Steady, Hubert. Jump off. Pick up papa's pistol. Arrange the horses in a triangle round him. That's right. Now don't throw away a shot."

The nearest Indian was scarcely thirty yards off when Charley's bullet crashed into his brain. The three immediately following him fell in rapid succession, another chief's arm sank useless to his side, while the horse of another fell, shot through the brain.

Both the boys were pale, but their hands were as steady as iron.

They felt as if, with their father lying insensible under their protection, they could not miss.

So terrible was the destruction which the continued fire wrought among the leaders that the others instinctively checked the speed of their horses as they approached the little group, from which fire and b.a.l.l.s seemed to stream, and began to discharge arrows at the boys, hanging on the other side of their horses, so that by their foes they could not be seen, a favorite maneuver with the Indians. As the boys fired their last barrels they drew their revolvers from the holsters, and, taking aim as the Indians showed a head or an arm under their horses' necks or over their backs, their twelve barrels added to the Indians scattered over the ground.

"Now, Hubert, give me the two last revolvers, and put the two fresh chambers into the carbines."

Seeing only one of their foes on the defense, the Indians again made a rush forward. Charley shot the two first with a revolver, but the others charged up, and he stooped a moment to avoid a spear, rising a little on one side, and discharging with both hands his pistols at the Indians, who were now close. "Quick, Hubert," he said, as he shot with his last barrel an Indian who had just driven his spear into the heart of Mr. Hardy's horse.

The animal fell dead as it stood, and the Indians with a yell charged at the opening, but as they did so Hubert slipped a carbine into his brother's hand, and the two again poured in the deadly fire which had so checked the Indians' advance.

The continuation of the fire appalled the Indians, and the seven that survived turned and fled.

"I will load, Hubert," Charley said, trying to speak steadily. "See to papa at once. Empty one of the water-gourds upon his face and head."

Hubert looked down with a cold shudder. Neither of the boys had dared to think during that brief fight. They had had many falls before on the soft turf of the pampas, but no hurt had resulted, and both were more frightened at the insensibility of their father than at the Indian horde which were so short a distance away, and which would no doubt return in a few minutes in overwhelming force.

Great, then, was Hubert's delight, when upon looking round he saw that Mr. Hardy had raised himself with his arms.

"What has happened?" he said in a confused manner.

"Are you hurt, papa?" Hubert asked, with tears of joy running down his face; "you frightened us both so dreadfully. Please drink a little water, and I will pour a little over your face."

Mr. Hardy drank some water, and Hubert dashed some more in his face. "That will do, Hubert," he said with a smile; "you will drown me. There, I am all right now. I was stunned, I suppose. There you are," and he got up on to his feet; "you see I am not hurt. And now, where are the Indians?"

"There, papa," said the boys with pardonable triumph, as they pointed to thirteen dead Indians.

Their father could not speak. He grasped their hands warmly. He saw how great the danger must have been, and how gallantly his boys must have borne themselves.

"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 la.s.so, 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 toward home, when we started; so the Indian halting-place is to the southeast of us, is it not?"

"Yes, papa; as near as may be," Charley said, making out the points with some difficulty on the pocket compa.s.s, 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."

At the end of that time they again closed up.

"Now, boys, you see that bright star. That is nearly due east of us; go on as nearly as you can guess for ten minutes, at a walk, as before. You will then be within a mile of the enemy. Then get off your horses. Mind, on no account whatever are you to leave their bridles, but stand with one hand on the saddle, ready to throw yourself into it. Keep two blue-lights, and give me one. Don't speak a word, but listen as if your lives depended upon detecting a sound, as indeed they do. You are to remain there until you see that I have fairly succeeded and then you are to dash in behind the cattle and fire off your revolvers, and shout so as to quicken their pace as much as possible. I do not think there is the least fear of the Indians following, the rockets will scare them too much. When you have chased the herd for about two miles, draw aside half a mile on their side, and then listen for the Indians pa.s.sing in pursuit of the cattle; wait ten minutes, and then blow your dog-whistle--a sharp, short note. If you hear Indians following you, or think there is danger, blow twice, and go still further to the right. G.o.d bless you, boys. I don't think there is much fear of your falling upon any scouts; they have been too badly cut up to-day, and must look upon our guns as witches. I need not say keep together, and, if attacked, light a blue-light and throw it down; ride a short way out of its circle of light, and I will come straight to you through everything. Don't be nervous about me.

There is not the least danger."

In another minute the boys lost sight of their father, and turning their horses proceeded in the direction he had ordered. Every now and then they stopped to listen, but not a sound could they hear.

Their own horses' hoofs made no noise as they fell upon the soft turf.

At the end of the ten minutes, just as Charley was thinking of stopping, they heard a sound which caused them to halt simultaneously. It was the low baa of a sheep, and seemed to come from directly ahead of them. Charley now alighted, and Hubert brought his horse up beside him, keeping his place, however, in the saddle, but leaning forward on the neck of his horse, for he felt that if he got off he should be unable to regain his seat hurriedly in case of alarm.

"About a mile off, I should say, by the sound," Charley whispered; "and just in the direction we expected."

The spot Charley had chosen for the halt was a slight hollow, running east and west; so that, even had the moon been up, they would not have been visible except to any one in the line of the hollow.

Here, their carbines c.o.c.ked and ready for instant use, they remained standing for what appeared to them ages, listening with the most intense earnestness for any sound which might tell of the failure or success of their father's enterprise.

Mr. Hardy had ridden on for, as nearly as he could tell, two miles, so that he was now to the southwest of the enemy; then, turning west, he kept along for another mile, when he judged that he was, as nearly as possible, a mile in their direct rear. He now advanced with the greatest caution, every faculty absorbed in the sense of listening. He was soon rewarded by the sound of the baaing of the sheep; and dismounting and leading his horse, he gradually approached the spot. At last, on ascending a slight rise, he fancied that he could make out a black ma.s.s, at a distance of a quarter of a mile. Of this, however, he was not certain; but he was sure, from an occasional sound, that the herd was exactly in this direction, and at about that distance.
