When a husband or wife has died at sea, when the ship has made more than half of her trip, the survivor must pay or serve not only for himself or herself, but also for the deceased. When both parents have died over halfway at sea, their children, especially when they are young and have nothing to pawn or to pay, must stand for their own and their parents' passage, and serve till they are twenty-one years old. When one has served his or her term, he or she is entitled to a new suit of clothes at parting; and if it has been so stipulated, a man gets in addition a horse, a woman, a cow."
