“Believe me, my young friend, there is nothing—absolutely nothing—half so much worth doing as simply messing about in boats,” says Rat, and his sentiment rings with truth (and inspired the delightful grass-roots magazine, “Messing About in Boats,” which I highly recommend to any part-time sailor). The narrative arc of this story treks from a slow start with Mole’s adventures and Rat’s waterfront life toward rescuing Toad, whose character drives the plot toward a happy ending. Well-developed characters, all exhibiting behaviors similar to their nonfiction animal cousins, make the premise believable. However, due to the laborious language (even if it’s beautifully descriptive, perceptive or astute) and lengthy and convoluted sentence structure (admittedly not unusual for 1908), I trudged through every page.
