Moby-Dick Questions Chs. 61-63: What color is the sperm whale that Stubb kills

What color is the sperm whale that Stubb kills (p. 308 [230]).  How do you interpret the “pipe-smoking” images in ch. 61, and what do they suggest about the relationship between Stubb and the whale?  How does the language of destructiveness and violence in this chapter compare with the language of productivity?  Why does Ishmael describe the killing of the whale in such detail, and how does he defend the cruelty and gore of whaling?
