What is Samuel's punishment for punching Richard in Chapter Eight?

Samuel makes fun of James for crying, and Richard defends him by calling Samuel names. There is a fight. Smith drags Samuel away and punishes him by making him stand on one foot. Because of the rocking of the ship, Samuel can't do it. Smith tells him that this is lesson for him on how they need to stand together to survive. He chains Samuel to the wall, saying that if he can't teach the gentlemen this lesson, he can at least teach his page.
