The Innocents Abroad was the account of a preplanned package tour; in A Tramp Abroad, Twain has to set his own agenda, and spends almost the entirety of the 600 pages in southern Germany and Switzerland. But at this point in his career Twain doesn't need much in the way of incident to fill a book. The slightest prompt can provide grist for a chapter or three, whether it be a rant about hotels, a retelling of a German fairy tale, a 50-page mountain climbing story piling absurdity on top of absurdity, a straightforward account of student duels in Heidelberg, an awestruck paean to the beauty of the Alps, you name it. It's as shapeless as a weblog, but thoroughly entertaining all the way through; Twain, about to run off a string of now-famous titles, has evolved from a guy who can crack a joke to one who can take a stage and keep an audience transfixed for hours, and not entirely with comedy.
