On his retirement as one of the leading advertising agents in New York City, EARNEST ELMO CALKINS devoted himself to the hobbies which had long been inviting his spare hours. He wrote about the ordeals and compensations of being deaf, and his autobiography, Louder, Please, is a standard in its field. He developed his passion for woodcarving, and from his bench has launched a fleet of precise and beautiful ship models. He also indulged himself in mathematics, as in this paper.
