The Baris are a great pastoral people, and possess immense herds of cattle. These are generally small active animals with humps; white is the prevailing colour. The sheep are small and the mutton is good; but although the fine pasturage of the Bari country is eminently adapted for sheep and goats, these animals are delicate, and require much attention during the heavy rains, at which time they are always kept beneath a roof at night, with fires composed of dry cow-dung to create a smoke that will drive away flies or mosquitoes. Like most of the tribes of the White Nile, the Baris have a strong objection to sell their cattle; thus you may be surrounded by plenty, but you may starve in the midst of beef. Their large herds are confined at night within zareebas or kraals. These are formidable defences. The cattle zareeba is a circular stockade formed of a hard wood called by the Arabs abou-noos or abdnoos (ebony). This is an intensely hard black wood somewhat resembling ebony. Piles as thick as a man's thigh are sunk in the earth, so as to leave a fence or stockade of about eight feet high above the surface; these piles are placed as close as possible together, and interlaced by tough hooked thorns, which when dry and contracted bind the stockade into a very compact defence. The entrance to this fort is only sufficiently large to admit one animal at a time; thus the herd can be easily counted. Within the stockade are several houses, in addition to a few large circular sheds for the protection of young calves. The sheep and goats are kept in a separate zareeba.
