Harold W. Felton, Bowleg Bill, Seagoing Cowpuncher, Englewood Cliffs, New Jersey, Prentice-Hall, 1957. From review: " The exuberant chronicle of the exploits of Bowleg Bill, an eight-foot cowboy who rides herd on giant tuna fish and she-whales and he-whales, makes the most of two professions given to tall tales -- whaling and bronco-busting. The mixture of the jargon of the range and the poop-deck add to the incongruity of this beef-and-blubber comedy."
