43. They copulate like horses, and produce young chiefly in the spring. It is the season for the male, when he is in heat and is ferocious. At this period he discharges some fatty matter through an opening in the temples. It is the season also for the females, when this same passage is open. Eighteen months is the longest, and sixteen the shortest period that they go with young. The dam suckles her young six years. Many of them live as long as men who attain to the greatest longevity, some even to the protracted age of two hundred years. They are subject to many diseases, which are difficult to be cured. A remedy for diseases of the eye is to bathe them with cow’s milk. For complaints in general, they drink dark wine. In cases of wounds, they drink butter; for it draws out iron instruments. Their sores are fomented with swine’s flesh. Onesicritus says, that they live three hundred years, and rarely five hundred; and that they go with young ten years. He and other writers say, that they are larger and stronger than the African elephants. They will pull down with their trunks battlements, and uproot trees, standing erect upon their hind feet. According to Nearchus, traps are laid in the hunting grounds, at certain places where roads meet; the wild elephants are forced into the toils by the tame elephants, which are stronger, and guided by a driver. They become so tame and docile, that they learn even to throw a stone at a mark, to use military weapons, and to be excellent swimmers. A chariot drawn by elephants is esteemed a most important possession, and they are driven without bridles.[384] A woman is greatly honoured who receives from her lover a present of an elephant, but this does not agree with what he said before, that a horse and an elephant are the property of kings alone. 44. This writer says that he saw skins of the myrmeces (or ants), which dig up gold, as large as the skins of leopards. Megasthenes, however, speaking of the myrmeces, says, among the Derdæ a populous nation of the Indians, living towards the east, and among the mountains, there was a mountain plain of about 3000 stadia in circumference; that below this plain were mines containing gold, which the myrmeces, in size not less than foxes, dig up. They are excessively fleet, and subsist on what they catch. In winter they dig holes, and pile up the earth in heaps, like moles, at the mouths of the openings.
