The life-cycle for both sexes was differentiated by important rituals. Both girls and boys underwent initiation. Boys (bašemane, later mašoboro) spent their youth looking after cattle at remote outposts, in the company of peers and older youths. Circumcision and initiation at koma (initiation school), held about once every five years, socialized youths into groups of cohorts or regiments (mephato) bearing the leader's name, whose members then maintained lifelong loyalty to each other, and often traveled together to find work on the farms or on the mines. Girls attended their own koma and were initiated into their own regiments (ditswa-bothuku), usually two years after the boys. Initiation is still practiced, and provides a considerable income to the chiefs who license it for a fee or, in recent years, to private entrepreneurs who have established initiation schools beyond chiefs' jurisdiction.
