"What is the matter, Dias?" he asked in surprise, as the latter ran up.

"That is a peccary."

"Well, it is a sort of pig, isn't it?"

"Yes, señor. But if you were to kill it, we might all be torn in pieces. They travel through the forests in great herds, and if one is injured or wounded, the rest will rush upon its assailants. You may shoot down dozens of them, but that only redoubles their fury. The only hope of escape is to climb a tree; but they will keep watch there, regardless of how many are shot, until hunger obliges them to retire. They are the bravest beasts of the forests, and will attack and kill even a lion or a tiger if it has seized one of their number. I beg you to stroll back quietly, and then sit down. I will go to the head of the mules. If the herd see that we pay no attention to them, they may go on without interfering with us. If we see them approaching us, and evidently intending to attack, we must take to the trees and try to keep them from attacking the mules; but there would be small chance of our succeeding in doing so."

He and José at once went up to the mules, and stood perfectly quiet at their head. Harry and Bertie moved closely up, laid their double-barrelled guns beside them, and then sat down. By this time forty or fifty of the peccaries had issued from the trees; some were rooting among the herbage, others stood perfectly quiet, staring at the group on the rise above them. Seeing no movement among them nor any sign of hostility, they joined the others in their search for food, and in a quarter of an hour the whole herd had moved off along the edge of the forest.

"Praise be to the saints!" Dias said, taking off his hat and crossing himself. "We have escaped a great danger. A hunter would rather meet a couple of lions or tigers than a herd of peccaries. These little animals are always ready to give battle, and once they begin, fight till they die. The more that are killed the more furious do the others become. Even in a tree there is no safety. Many a hunter has been besieged in a tree until, overpowered by thirst, he fell to the ground and was torn to pieces."

"What do they eat?" Harry asked.

"They will eat anything they kill, but their chief food is roots. They kill great numbers of snakes. Even the largest python is no match for a herd of peccaries if they catch him before he can take refuge in a tree."

"Well, then, it is very lucky that you stopped us before we fired."

"Fortunate indeed, señor. By taking to the trees we might have saved our lives, but we should certainly have lost our mules. Both pumas and tigers kill the little beasts when they come across stragglers. And it is well that they do, for otherwise the woods would be full of them, though fortunately they do not multiply as fast as our pigs, having only two or three in a litter. They are good eating, but it is seldom that a hunter can shoot one, for if he only wounds it, its shrieks will call together all its companions within a mile round."
