breed and not a bit better. Eatables are kept in swinging safes at the end of coir rope recently tarred. But when, in spite of these precautions, or from the neglect of them, you find, say your sugar, a brown, busy mass, just stand it in the full glare of the sun. Sun is a thing no ant likes, I believe, and it is particularly distasteful to ants with pale complexions; and so you can see them tear themselves away from their beloved sugar and clear off into a Hyde Park meeting smitten by a thunderstorm.

This kind of ant, or a nearly allied species, is found in houses in England, where it is supposed they have been imported from the Brazils or West Indies in 1828. Possibly the Brazils got it from South West Africa, with which they have had a trade since the sixteenth century, most of the Brazil slaves coming out of Congo. It is unlikely that the importation was the other way about; for exotic things, whether plants or animals, do not catch on in Western Africa as they do in Australia. In the former land everything of the kind requires constant care to keep it going at all, and protect it from the terrific local circumstances. It is no use saying to animal or vegetable, "there is room for all in Africa"—for Africa, that is Africa properly so called—Equatorial West Africa, is full up with its own stuff now, crowded and fighting an internecine battle with the most marvellous adaptations to its environment.
