What is the author's tone in Mark Twain's Letters from Hawaii by Mark Twain?

Twain's tone is defined by context. As a tourist, the author adopts the role of humorist, often painting himself in ridiculous or self-deprecating terms. Writing in this manner, Twain is verbose and florid. When annoyed, Twain shifts to a sarcastic, even mocking tone, whereon the author's language moves from florid to acerbic. Confronted with matters of commerce, Twain abruptly morphs to something of an accountant, his verbosity turned to the purpose of facts and figures. This version of the author leaves nothing to broad strokes, instead seeking to paint any and all relevant factors in meticulous, painstaking detail.
