Remarks.—Air of Unyanyembe intensely dry; sometimes does not rain for months. Soil fertile by proximity of water; rains every 15 or 16 days. Lightning from S.E. We had very steady rain. Thunder and lightning like chota barsát in Upper India. About the 30th inst. country well sopped. All began to plant; rice about end of month, and Jawari after.
Rain, as at Zanzibar, every day. Generally deep cloudy morns. Cold wind, and very damp. Therm. 70°. Sun at 10 a.m., hot. Clouds partially dispersed. About 2 p.m. showers, with thunder and lightning, increase till dark, when become very violent. Bolts fell one night. Climate unwholesome as the Kinga-ni river. Almost all our men had fever. Wind generally E., but changing to S.W.
This rain in Dec. is called Muaka, or the year. We experienced it on the coast, in the Elphinstone, and the Riami. All are cultivating.
