I'm concerned about Twain's use of enchantment in this chapter. Hank sees hogs, a pig sty and three swineherds. Sandy insists there is a castle with captive princesses and three giant ogres. Hank compromises with Sandy and hypothesizes that the enchantment is for his eyes. There is no explanation for this. I'm assuming that Twain started off this quest in some fantastic manner and could come to no other solution. In no other part of the book does Sandy exhibit such delirium and no other superstitions are represented in such a visual manner.
