The Kavirondo are essentially an agricultural people: both men and women work in the fields with large iron hoes. In addition to sorghum, Eleusine and maize, tobacco and hemp are both cultivated and smoked. Both sexes smoke, but the use of hemp is restricted to men and unmarried women, as it is thought to injure child-bearing women. Hemp is smoked in a hubble-bubble. The Kavirondo cultivate sesamum and make an oil from its seeds which they burn in little clay lamps of the ancient saucer type, the pattern being, in Hobley's opinion, introduced into the country by the coast people.
