Considering all the northerners were said to have been driven up here by the war, I was much surprised to see so few habitations or flocks in the valley; all there were consisted in a few kraals scattered over the plain, which were constantly moved as soon as each plot of ground in turn was eaten up by the cattle. In changing ground, these nomads pack up everything on their camels, mat and stick, hut and all, and placing the wife, with perhaps a baby also, on a donkey, march to any unoccupied watering-place they can find. Their food is very limited, except in the rainy season, when milk prevails: in consequence of this, it being now the dry season, my servants accounted for their increasing appetite for my dates. Some of the poorer men are said to pass their whole lives without tasting any flesh or grain, but to live entirely on sour milk, wild honey, or gums, as they may chance to come across them, and they are almost naked; but notwithstanding this, disease is scarcely known, and excepting in a few cases of endemic ophthalmia, which appears to attack the country periodically, at intervals of two or three years, I never heard of any. The climate was very delightful at this season, and the nights so cold I had to wrap myself well up in flannels. But perhaps that which best illustrates the healthiness of the country and pleasantness of its atmosphere, is the fact that I, although I had no bedstead, but always slept on the ground, never pitched my tent a single day in the interior, and neither wore a hat or shoe throughout the journey, save on one or two occasions, when, severely stabbed with thorns, I put on a sandal. I never knew a moment's illness.
