This curious colony of birds afforded us matter for conversation as we went on our way; their cheerful, sociable habits, and the instinct which prompted them to unite in labor for the common good, appearing most wonderful to us. "Examples of the kind, however," said I, "are numerous, in various classes of animals. Beavers, for instance, build and live together in a very remarkable way. Among insects, bees, wasps, and ants are well known as social architects; in like manner, the coral insect works wonders beneath the ocean waves, by force of perseverance and united effort." "I have often watched ants at work," said Fritz; "it it most amusing to see how they carry on the various works and duties of their commonwealth." "Have you ever noticed how much trouble they take with the eggs?" inquired I, to see how far he understood the process; "carrying them about in the warmth of the sun until they are hatched?" "Ah! that is rather the chrysalis of the antworm, or larva, which is produced from an egg. I know they are called ants' eggs, but, strictly speaking, that is incorrect." "You are perfectly right, my boy. Well, if you have taken so much interest in watching the little ants of your native country, how delighted and astonished you would be to see the wonders performed by the vast tribes of large ants in foreign lands. "Some of these build heaps or nests, four or six feet high and proportionately broad, which are so strong and firm that they defy equally sunshine and rain. They are, within, divided into regular streets, galleries, vaults, and nurseries. So firmly are these mounds built, that with interior alterations, a deserted one might be used for a baking oven. "The ant, although respected since the days of King Solomon as a model of industry, is not in itself an attractive insect. "It exudes a sticky moisture, its smell is unpleasant, and it destroys and devours whatever eatable comes in its way. Although, in our own country it does little harm, the large ants of foreign lands are most destructive and troublesome; it being very difficult to check their depredations. Fortunately they have enemies by whose exertions their numbers are kept down; birds, other insects, and even four-footed beasts prey upon them. Chief among the latter is the ant-bear, or tamanoir, of South America, a large creature six or seven feet in length, covered with long coarse hair, drooping like a heavy plume over the hind quarters. The head is wonderfully elongated and very narrow; it is destitute of teeth, and the tongue resembles somewhat a great red earth-worm. It has immensely strong curved claws, with which it tears and breaks down and scratches to pieces the hard walls of the ant-heaps; then, protruding its sticky tongue it coils and twists it about among the terrified millions disturbed by its attack; they adhere to this horrible invader, and are drawn irresistibly backward into the hungry, toothless jaws awaiting them.
