BOSK

"The bosk is said to be the Mother of the Wagon Peoples, and they reverence it as such. The man who kills one foolishly is strangled in thongs or suffocated in the hide of the animal he slew; if, for any reason, the man should kill a bosk cow with unborn young he is staked out, alive, in the path of the herd, and the march of the Wagon Peoples takes its way over him."
Nomads of Gor, pg 5
