We have seen that Huxley admits reluctantly that most animals have those portions of brain development that we believe to be the seat of consciousness, but here is an insect with organs and functions as heterogeneous from our own as can well be imagined, and yet there is no mode of life that men have tried which one or another of the races of ants is not pursuing to-day. Beside the agriculturists and herdsmen, some keep slaves to do everything for them, some live by hunting and plunder, while others quarter themselves upon us and live by confounding meum and tuum. Any ardent pomologist may study the herdsmen tribes by simply turning over the leaves of his young apple tree in the spring. Upon the broad succulent meadows of the under side of his foliage he will discover fat flocks of aphis cows, tended by brawny ant cow-herds, who keep a special eye upon the big brown bulls around which the cows and calves gather to feed. The herdsmen conduct them from leaf to leaf as they exhaust the sap, and at night by the long twig paths and barky roads they carry the milk of the sweet honey dew with which they are swollen. If the horticulturist be hard of heart and smear away a whole herd with a sweep of his thumb, the horrified herdsmen will rush frantically home, bursting into the nest to report to some hyksos king of the termites, that the Philistines have fallen upon his charge and that "I, only I, have escaped to tell the tale!" The most interesting of the agricultural races of ants is that one commonly known in the West Indies as the parasol ant, from its fashion of carrying bits of flower petals over its shoulder at the angle commonly used with a sunshade. This ant erects an enormous structure, as large in proportion to its size as is the City of London to any one of its inhabitants. The dwellers in these cities are divided into classes: farmers, road-makers, explorers, nurses, soldiers, street sweepers, policemen, and, of course, the Queen. The great town is kept perfectly clean and sanitary by the scavengers, who remove all refuse every day. In case of death the bodies are removed some distance and buried. The soldiers guard the entrances to the city, and in case of attack by one of the Attila hordes of the barbarian hunter ants, they fight with a fury and courage so great that only after the entire army is destroyed is the city ever given up to pillage.
