In a catchy way, Melvern Barker's blue and brown pictures and his rhythmical text outline the core of boatyard activity as Jimmy Jim sees it. Going to the waterfront one day, small Jimmy Jim watches six dungareed, chanty-chanting workers lay the keel, nail up ribs, boards, mast and so forth, of a very neat little boat. By the time it's been launched, so has a good bit of boatyard data. Homorous and direct.
