to the farm. I mention these incidents to show there is something more than instinct in all living things. The country round this part of Monkuruan territory, and in fact all Africa, swarms with every kind of ant, from the smallest size up to three-quarters of an inch in length, each kind having their own peculiar form of nest, more particularly the destructive white ant, which causes so much damage to buildings and furniture; the construction of their nests differs in different latitudes. In the Cape Colony, Natal, Orange Free State, and lower part of the Transvaal, the veldt is covered with these hills, in the shape of a ball cut in halves and placed on the ground; the average size is four feet in diameter by two feet in height; many of them have been scooped out by ant-bears. The Dutch women, in travelling, frequently make use of these holes, by turning them into ovens to bake their bread for the road. More to the north, instead of being round, they form a kind of peak, with holes on the topmost points, some exceeding in height twenty feet. North of this again the ground is raised some two feet by ten to fifteen in diameter. On the centre part chimneys are built up, many exceeding four feet in height, by nearly three feet in circumference; the opening is nearly a foot in diameter, the top terminating in a cup-like form, in three distinct layers, one above the other, forming quite an ornamental termination to the chimney beautifully constructed. On looking down, hundreds of these tiny masons may be seen plastering and repairing the inside coating, which may have received damage from rain. There is always one large chimney, and sometimes one or two smaller ones close to it, and at the base some twenty or thirty small ones, three inches to a foot in height, and three and four inches in diameter, and many small holes round about, where the ants are busy taking in their food, small pieces of dried grass, and other things, never making use of the chimneys as a means for supplying their cells with food. They are, I believe, erected as ventilators to give air below, as the cavity beneath must be as large as a small room, and in some eases larger, as a waggon fell into one. A road had been made near Molapo, over one of these disused nests, and in 1877 a Boer waggon was travelling in the night, as is their usual practice. The front oxen had gone over it, the ground gave way with the after oxen, but they managed to get on firm ground; the weight of the waggon broke the top surface, and only the desselboom on the opposite side getting fixed, kept the two fore-wheels and waggon suspended over the hole, a Boer woman and three children narrowly escaping from falling into the pit. I followed up the next morning, when the Boer and others were getting the waggon mended; bushes were then put round the hole and the road turned. If I had passed over this road before that waggon I should have met the same fate. As a whole,
