87:2.8

It was customary to dispatch a large number of subjects to accompany a dead chief; slaves were killed when their master died that they might serve him in ghostland. The Borneans still provide a courier companion; a slave is speared to death to make the ghost journey with his deceased master. Ghosts of murdered persons were believed to be delighted to have the ghosts of their murderers as slaves; this notion motivated men to head hunting.
