Generation after generation supplies its quota of a potential market for another castaway story. Think of the classics of the type,- Robinson Crusoe, Swiss Family Robinson, Treasure Island, and so on. Two of the three are as apt to appear on adult lists as on juveniles, if truth be told. Now comes this entertaining bit of sheer escape in a convincing story -- purporting to be a log belonging to the author's great-uncle. As the story unfolds, one is convinced that here is the day by day record of a youth, shipwrecked with a group of cut throats and wretches, and finding in himself unguessed ingenuities, skills, abilities to fend for himself and fight his own battles. Eventually, having explored one island, entrenched himself on another, and reduced his foes to one, he makes friends with Dandy and together they escape to Australia and the gold fields. There's romance, too, and throughout the adventures are as bloody and as fortunate in their outcome, the lady as fair, the finale as bright as the best of the dreams we'd like to dream. Astonishingly entertaining reading, with a plus market for boys.
