Mr. Southey states that in Brazil “the Spaniards pulverize the nests of the Termites, and with the powder form a flooring for their houses, which becomes as hard as stone, and on which it is said no fleas or other insects will harbor.”[456] The early Spanish settlers built the walls of their houses of the same earth; and some of which, which were erected in the seventeenth century, are said to be still in existence.[457] Ant-hills, or rather the Termites which inhabit them, have also been used as an instrument of perhaps the most infernal torture the ingenuity of man has ever invented. For, in South Africa, at one time, the wretched victim, whether prisoner of war or offending subject, having been smeared with some oily substance, was partially interred in one of these heaps, and, if not first roasted to death by the burning sun, was literally devoured alive by the myriads of insects which have their habitation there. It has been asserted that even some Englishmen have met this dreadful fate.[458] At Unyamwezi, in the lake regions of Central Africa, the natives chew the clay of Ant-hills as a substitute when their tobacco fails. They call this clay “sweet earth.” It is said the Arabs have also tried it without other effects than nausea.[459] The goldsmiths of Ceylon employ the powdered clay of Ant-hills in preference to all other substances in the preparation of crucibles and moulds for their fine castings, for so delicate is the trituration to which the Termites subject this material;[460] and Knox says, “the people use this finer clay to make their earthen gods of, it is so pure and fine.”[461] Termites, as an article of food, are eaten by the inhabitants of many countries. Mr. Kœnig, in his essay on the history of these insects, read before the Society of Naturalists of Berlin, tells us, that to catch the Termites before their emigration, the natives of the East Indies make two holes in the nest, one to windward, and the other to leeward; at the latter aperture, they place a pot, rubbed with aromatic herbs. On the windward side they make a fire, the smoke of which drives these insects into the pots. By this method they take a great quantity, of which they make, with flour, a variety of pastry, which they sell to the poorer people. This author adds, that in the season in which this aliment is abundant, the abuse of it produces an epidemic colic and dysentery, which carries off the patient in two or three hours.[462]
