We wished to avoid the tsetse of our former path, so kept a course on the magnetic meridian from Lurilopepe. The necessity of making a new path much increased our toil. We were, however, rewarded in lat. 18 Degrees with a sight we had not enjoyed the year before, namely, large patches of grape-bearing vines. There they stood before my eyes; but the sight was so entirely unexpected that I stood some time gazing at the clusters of grapes with which they were loaded, with no more thought of plucking than if I had been beholding them in a dream. The Bushmen know and eat them; but they are not well flavored on account of the great astringency of the seeds, which are in shape and size like split peas. The elephants are fond of the fruit, plant, and root alike. I here found an insect which preys on ants; it is about an inch and a quarter long, as thick as a crow-quill, and covered with black hair. It puts its head into a little hole in the ground, and quivers its tail rapidly; the ants come near to see it, and it snaps up each as he comes within the range of the forceps on its tail. As its head is beneath the ground, it becomes a question how it can guide its tail to the ants. It is probably a new species of ant-lion ('Myrmeleon formicaleo'), great numbers of which, both in the larvae and complete state, are met with. The ground under every tree is dotted over with their ingenious pitfalls, and the perfect insect, the form of which most persons are familiar with in the dragon-fly, may be seen using its tail in the same active manner as this insect did. Two may be often seen joined in their flight, the one holding on by the tail-forceps to the neck of the other. On first observing this imperfect insect, I imagined the forceps were on its head; but when the insect moved, their true position was seen. The forest, through which we were slowly toiling, daily became more dense, and we were kept almost constantly at work with the axe; there was much more leafiness in the trees here than farther south. The leaves are chiefly of the pinnate and bi-pinnate forms, and are exceedingly beautiful when seen against the sky; a great variety of the papilionaceous family grow in this part of the country.
