But neither time nor place would permit of carrying out the Don’s desires, as there was neither water nor pasture for the animals. The Don’s remark about the peccaries paying us a visit is owing to a popular belief that these animals, when in considerable numbers, will follow a dog’s trail for many miles, and attack and kill him. In fact, it is customary with the hunters to imitate the barking of a dog to attract the attention of the pigs, and induce them to collect together and make an attack; when, the hunters being safely ensconced in trees, the game is perfectly safe, as the men have only to shoot what they require.

The ground traversed that afternoon was not so free from bush as we had hitherto found, being in many places thickly covered with dense cerrado (abounding in immense quantities of the india-rubber-producing Mangaba-tree), where progress was very slow and difficult, and required the free use of our wood-knives. After a long and wearisome march, we reached the valley of the Sapão again, quite eight miles from the peccaries’ haunt.

I found the river valley presented much the same characteristics as we had found lower down. For the purposes of a railway it is admirable; the gradients are practically level, and the only works of art required would be in crossing the many burity swamps that intersect the route, and these, although numerous, are narrow.

Even the Rio Sapão itself could doubtless be made into a good canal, in the absence of a railway, for there is plenty of water, and the ground offers great facilities for straightening its course.

Especial care was taken in preparing the camp that night. The Don and José superintended the operation of constructing the fort, the sides of which were further protected by spreading over them the hides used for covering the packs of the mules. Bush was also cut to make up and enlarge the defences, and a strong stake was driven into the ground inside the fort for the purpose of securing the dogs in case the peccaries arrived. The camp was made on the borders of a clump of trees, to which we were enabled to sling the hammocks, no one caring to sleep on terra firma that night, but two of the men who were unprovided with hammocks spread their hides on the ground inside the fort.

After dinner, of course, peccaries formed the sole subject of conversation, but hour after hour went by, yet no signs of their presence appeared; and, after arranging the watches for the night, we turned in, and with the fatigues of the day I was soon asleep.

It appeared to me, however, that I had barely closed my eyes, when I felt my hammock violently shaken. It was the Don awakening me, saying, “Wake up, here are the porcos, we are going to have some fun.” The first peculiarity that struck me was the prevalence of the odor of old pigsties. I sat up, looked around, and listened. The pitchy blackness of night surrounded us, but the fire, burning brightly, sent its flickering light upon the tree-trunks, the foliage, and the hammocks; two men were in the fort with gun and knife in hand, and the dogs tied to their stake were with difficulty kept quiet, and vented their excitement in deep growls. As I listened it became evident that we were surrounded by some animals, for in many directions was heard, in the stillness of night, the sound of bodies moving through the bush, twigs snapping, grass rustling, etc. It was a moment of suspense, but not for long; for suddenly, from all around us, came a blood-curdling sound of the simultaneous snapping of teeth from vast numbers of the enemy, followed by the appearance of a crowd of charging black animals, rushing with wonderful speed towards a common centre, the fort. We in the hammocks each lighted a coil of wax tapers that were prepared ready for the occasion.

And what a scene ensued! the fire was rapidly scattered, and partly extinguished; under and around us was a seething mass of black peccaries, barely distinguishable in the dim light, but all pushing and struggling to the front; the men in the fort had discharged their weapons, and were hard at work, hacking and thrusting at the peccaries as they endeavored to swarm up the smooth surface of the hides that covered the sides of the fort. The men in the hammocks, after discharging their guns, reached down and slashed with their knives at the swarming animals below them.

The attack was more like the wild, reckless bravery of the Arabs of the Soudan, for as pig after pig fell squealing and disabled, scores more struggled for his place. The faint light of the tapers and the partly extinguished fire served but to dimly illuminate the elements of the strange, noisy, wildly weird scene; the trunks of the surrounding trees and their foliage; the swinging hammocks with their occupants reaching downward, cutting and thrusting with their long, gleaming knives; the dim figures of the men in the trincheria, repelling with shouts and thrusts the swarming enemy; the wild, rushing, charging forms of the black bodies of the peccaries, as in great numbers they threw themselves against the fort, regardless of being struck down one after the other, and always impelled forward by those in the rear struggling to the front; others made ineffectual attempts to reach our hammocks or viciously gashed the trees that gave us support; the extremely disagreeable and nauseous odors of the animals, their snapping of teeth, like musketry file-firing, the reports of the firearms, the shouts of the men, the howling and barking of the dogs, and the dim light, created an indescribably strange and exciting scene. Every bullet of my revolver took effect. I shouted to the men to reserve their fire, and fire volleys, but it was like talking in a gale of wind at sea.

In spite of all efforts, still the battle raged. The animals appeared to be in immense numbers, for, as far as the faint light would permit, the ground was seen covered with their moving bodies, rushing, struggling, the strongest beating down the weakest, grunting, squealing, and snapping their teeth; and noticeable above everything was the abominable exhalations from their bodies, an odor like a combination of rank butter and garlic.
