ran over the surface of the tree with great agitation, those within receiving notice of the danger, and probably by the same means, came out in a crowd and joined this tumult. The same signal which produced upon the workers this effect, caused a different impression upon the males and females; as soon as one of the labourers had informed them of their danger, they sought an asylum, and re-entered precipitately the trunk of the tree;—not one thought of quitting its temporary shelter, until a worker approached and gave them the signal for flight. The solicitude of the labourers in their favour, is manifested in the activity they display, in giving them advice or intimating to them the order for their departure; they redouble then the above signals, as if conscious of their understanding their intent less readily than the companions of their labours; the latter understand them, if I may use the expression, at half a word."

"Of all the enemies of the ant, those most dreaded are the ants themselves; the smallest not the least, since several fasten at once upon the feet of the largest, drag them to the ground, embarrass their movements, and thus prevent their escape. One would be astonished at the fury of these insects in their combats; it would be more easy to tear away their limbs and cut them to pieces, than compel them to quit their hold. It is nothing uncommon to see the head of an ant suspended to the legs or antennæ of some worker, who bears about, in every place, this pledge of his victory. We also observe, not unfrequently, the ants dragging after them the entire body of some enemy they had killed some time before, fastened to their feet in such a way as not to allow of their disengaging themselves.

"Supposing the ants to be of equal size, those furnished with a sting have an advantage over those who employ only for their defence their venom and their teeth. The whole of those ants whose peduncles has no scale, but one or two knots, are provided with a sting; the Red Ants, which are said to sting more sharply than the rest, possess both these sorts of arms. In general the ants furnished with a sting are, in our country, some of the smallest. I know but one species of middle size; but it is very rare and only inhabits the Alps.

"The wars entered into by ants of different size bear no resemblance to those in which ants engage who come to combat with an equal force. When the large attack the small, they appear to do it by surprise, most likely to prevent the latter from fastening upon their legs; they seize them in the upper part of the body and strangle them immediately between their pincers. But when the small ants have time to guard against an attack, they intimate to their companions the danger with which they are threatened, when the latter arrive in crowds to their assistance. I have witnessed a battle between the Herculean and the Sanguine Ants; the Herculean Ants quitted the trunk of the tree in which they had established their abode, and arrived to the very gates of the dwelling of the Sanguine Ants; the latter, only half the size of their adversaries, had the advantage in point of number; they however acted on the defensive. The earth, strewed with the dead bodies of their compatriots, bore witness they had suffered the greatest carnage; they therefore, took the prudent part of fixing their habitation elsewhere, and with great activity transported to a distance of fifty feet from the spot, their companions, and the several objects that interested them. Small detachments of the workers were posted at little distances from the nest, apparently placed there to cover the march of the retreats and to preserve the city itself from any sudden attack. They struck against each other when they met, and had always their mandibles separated in the attitude of defiance. As soon as the Herculean Ants approached their camp, the centinals in front assailed them with fury; they fought at first in single combat. The Sanguine Ant threw himself upon the Herculean Ant, fastened upon its head, turned its abdomen against the chest of its adversary or against the lower part of its mouth, and inundated it with venom. It sometimes quitted its antagonist with great quickness: more frequently, however, the Herculean Ant held between its feet its audacious enemy. The two champions then rolled themselves in the dust and struggled violently. The advantage was at first in favour of the largest ant; but its adversary was soon assisted by those of its own party who collected around the Herculean Ant and inflicted several deep wounds with their teeth. The Herculean Ant yielded to numbers[3]; it either perished the victim of its temerity, or was conducted a prisoner to the enemy's camp.

"Such are the combats between ants of different size; but if we wish to behold regular armies war in all its form, we must visit those forests in which the Fallow Ants establish their dominion over every insect in their territory. We shall there see populous and rival cities, regular roads passing from the ant hill as so many rays from a centre, and frequently by an immense number of combatants, wars between hordes of the same species for they are naturally enemies and jealous of the territory which borders their own capital. It is in these forests I have witnessed the inhabitants of two large ant-hills engaged in spirited combat. I cannot pretend to say what occasioned discord between these republics. They were composed of ants of the same species, alike in their extent and population; and were situated about a hundred paces distance from each other. Two empires could not possess a greater number of combatants.

"Let us figure to ourselves this prodigious crowd of insects covering the ground lying between these two ant-hills, and occupying a space of two feet in breadth. Both armies met at half-way from their respective habitations, and there the battle commenced. Thousands of ants took their station upon the highest ground, and fought in pairs, keeping firm hold of their antagonists by their mandibles; a considerable number were engaged in the attack and leading away prisoners. The latter made several ineffectual efforts to escape, as if aware that, upon their arrival at the camp, they would experience a cruel death. The scene of warfare occupied a space of about three feet square; a penetrating odour exhaled from all sides; numbers of dead ants were seen covered with venom. Those ants composing groups and chains, took hold of each other's legs and pincers, and dragged their antagonists on the ground. These groups formed successively. The fight usually commenced between two ants, who seized each other by the mandibles, and raised themselves upon their hind legs, to allow of their bringing their abdomen forward, and spirting the venom upon their adversary. They were frequently so closely wedged together that they fell upon their sides, and fought a long time in that situation, in the dust; they shortly after raised themselves, when each began dragging its adversary; but when their force was equal, the wrestlers remained immoveable, and fixed each other to the ground, until a third came to decide the contest. It more commonly happened that both ants received assistance at the same time, when the whole four, keeping firm hold of a foot or antenna, made ineffectual attempts to gain the battle. Some ants joined the latter, and these were, in their turn seized by new arrivals. It was in this way they formed chains of six, eight, or ten ants, all firmly locked together; the equilibrium was only broken when several warriors, from the same republic, advanced at the same time, who compelled those that were enchained to let go their hold, when the single combats again took place.
