This kind of procession is common at Zanzibar: when any demoniacal possessions take place among the blacks, it is by this means they cast out devils. While on the subject of superstition, it may be worth mentioning what long ago struck me as a singular instance of the effect of supernatural impression on the uncultivated mind. During boyhood my old nurse used to tell me with great earnestness of a wonderful abortion shown about in the _fairs_ of England--a child born with a pig's head; and as solemnly declared that this freak of nature was attributable to the child's mother having taken fright at a pig when in the interesting stage. The case I met in this country was still more far-fetched, for the abortion was supposed to be producible by indirect influence on the wife of the husband taking fright. On once shooting a pregnant doe waterboc, I directed my native huntsman, a married man, to dissect her womb and expose the embryo; but he shrank from the work with horror, fearing lest the sight of the kid, striking his mind, should have an influence on his wife's future bearing, by metamorphosing her progeny to the likeness of a fawn. 19th.--We bade Kurua adieu in the early morning, as a caravan of his had just arrived from Karagué, and appointed to meet at the second station, as marching with cattle would be slow work for him. Our march lasted nine miles. The succeeding day we passed Ukumbi, and arrived at Uyombo. On the way I was obliged to abandon one of the donkeys, as he was completely used up. This made up our thirty-second loss in asses since leaving Zanzibar. My load of beads was now out, and I had to purchase rations with cloth--a necessary measure, but not economical, for the cloth does not go half as far as beads of the same value. I have remarked throughout this trip, that in all places where Arabs are not much in the habit of trading, very few cloths find their way, and in consequence the people take to wearing beads; and beads and baubles are the only foreign things much in requisition.
