On a hill at Bomma near the mouth of the Congo dwells Namvulu Vumu, King of the Rain and Storm. Of some of the tribes on the Upper Nile we are told that they have no kings in the common sense; the only persons whom they acknowledge as such are the Kings of the Rain, _Mata Kodou,_ who are credited with the power of giving rain at the proper time, that is, the rainy season. Before the rains begin to fall at the end of March the country is a parched and arid desert; and the cattle, which form the people's chief wealth, perish for lack of grass. So, when the end of March draws on, each householder betakes himself to the King of the Rain and offers him a cow that he may make the blessed waters of heaven to drip on the brown and withered pastures. If no shower falls, the people assemble and demand that the king shall give them rain; and if the sky still continues cloudless, they rip up his belly, in which he is believed to keep the storms. Amongst the Bari tribe one of these Rain Kings made rain by sprinkling water on the ground out of a handbell. Among tribes on the outskirts of Abyssinia a similar office exists and has been thus described by an observer: "The priesthood of the Alfai, as he is called by the Barea and Kunama, is a remarkable one; he is believed to be able to make rain. This office formerly existed among the Algeds and appears to be still common to the Nuba negroes. The Alfai of the Barea, who is also consulted by the northern Kunama, lives near Tembadere on a mountain alone with his family. The people bring him tribute in the form of clothes and fruits, and cultivate for him a large field of his own. He is a kind of king, and his office passes by inheritance to his brother or sister's son. He is supposed to conjure down rain and to drive away the locusts. But if he disappoints the people's expectation and a great drought arises in the land, the Alfai is stoned to death, and his nearest relations are obliged to cast the first stone at him. When we passed through the country, the office of Alfai was still held by an old man; but I heard that rain-making had proved too dangerous for him and that he had renounced his office."
