Excepting in the neighbourhood of the villages which we have passed there were no traces of cultivation. The country extending between the several stations is as much a wilderness as the desert of Sahara, though it possesses a far more pleasing aspect. Indeed, had the first man at the time of the Creation gazed at his world and perceived it of the beauty which belongs to this part of Africa, he would have had no cause of complaint. In the deep thickets, set like islets amid a sea of grassy verdure, he would have found shelter from the noonday heat, and a safe retirement for himself and spouse during the awesome darkness. In the morning he could have walked forth on the sloping sward, enjoyed its freshness, and performed his ablutions in one of the many small streams flowing at its foot. His garden of fruit-trees is all that is required; the noble forests, deep and cool, are round about him, and in their shade walk as many animals as one can desire. For days and days let a man walk in any direction, north, south, east, and west, and he will behold the same scene. Earnestly as I wished to hurry on to Unyanyembe, still a heart-felt anxiety about the arrival of my goods carried by the fourth caravan, served as a drag upon me and before my caravan had marched nine miles my anxiety had risen to the highest pitch, and caused me to order a camp there and then. The place selected for it was near a long straggling sluice, having an abundance of water during the rainy season, draining as it does two extensive slopes. No sooner had we pitched our camp, built a boma of thorny acacia, and other tree branches, by stacking them round our camp, and driven our animals to grass; than we were made aware of the formidable number and variety of the insect tribe, which for a time was another source of anxiety, until a diligent examination of the several species dispelled it. As it was a most interesting hunt which I instituted for the several specimens of the insects, I here append the record of it for what it is worth. My object in obtaining these specimens was to determine whether the genus _Glossina morsitans_ of the naturalist, or the tsetse (sometimes called setse) of Livingstone, Vardon, and Gumming, said to be deadly to horses, was amongst them. Up to this date I had been nearly two months in East Africa, and had as yet seen no tsetse; and my horses, instead of becoming emaciated--for such is one of the symptoms of a tsetse bite--had considerably improved in condition. There were three different species of flies which sought shelter in my tent, which, unitedly, kept up a continual chorus of sounds--one performed the basso profondo, another a tenor, and the third a weak contralto. The first emanated from a voracious and fierce fly, an inch long, having a ventral capacity for blood quite astonishing.
