These are the duties of the overseer: He should maintain discipline. He should observe the feast days. He should respect the rights of others and steadfastly uphold his own. He should settle all quarrels among the hands; If any one is at fault he should administer the punishment. He should take care that no one on the place is in want, or lacks food or drink; in this respect he can afford to be generous, for he will thus more easily prevent picking and stealing.
