Almost the first thing the men did after the final retreat of the peccaries was to slash the skin on the top of the loins of the defunct enemy, and extract the gland that creates the disgusting odor peculiar to these animals; for if not extracted soon after death, it taints the flesh to such an extent as to render it uneatable except by Indians, who do not object to any flavor, and eat all their animal food cooked on the same principle as a European cook prepares a woodcock. There were twenty-seven dead pigs found in and about the camp, and also several wounded, to whom it was necessary to give the _coup de grace_. The wounds were mostly from the knives and small axes, but a very considerable number of the wounded must have got away to recover, or linger unfortunately in pain. Six of the plumpest were selected for drying and salting, the preparations for which, and also to repair the damages done to the bags of provisions, delayed our departure for some time. An examination of these animals showed them to be a species of peccary resembling that known as the _Dicotyles labiatus_, but an essential difference was noticeable in the absence of the white lips that give the name to that species; our enemies had black snouts and dark lips, otherwise they corresponded in other points. They had four incisors on the upper jaw, and six molars on each side above and below; while the tusks, although smaller than a pig's, are much finer and sharper, inclined slightly backward, and closely overlap each other. Some of the bodies of the animals measured thirty-six inches in length. They are more slender in build than the common pig, and covered with long, stiff bristles, colored with alternate rings of gray, light-brown, and black. These colors vary with the size and age of the animals, and as either one predominates, they cause the animal to appear either brown, gray, or black; the largest we found was almost entirely black, whereas the smallest had quite a brown appearance. During the battle I could not help noticing the apparent method of their movements, as though they were led by chiefs. It appears that their mode of attack on such an occasion as they favored us with is to surround in silence, by a complete circle, the object to be stormed; when, at a given signal, a simultaneous snapping of teeth takes place, followed by a general converging rush to the centre, whereby the largest and strongest reach the front first, and the smallest bring up the rear; their retreat is carried out on an equally methodical system. There is a small, red species known by the Guarany name of _caeitatu_;[B] our friends are known by the Brazilian cognomen of _queixadas_, or _porcos de matto_. [Footnote B: _Dicotyles torquatos._]
