This is a sequel to Macaroni, and is once more a story of the Italian-American lad whose father was a fiddle-maker and repairer, and who longed to be part of the gang of boys in the big American city to which he had come to live. This time the story revolves around the loss of a piece of a valuable broken fiddle, and of how the boys turned detective and eventually found the piece. As a story, it is somewhat anticlimactic; as a good background book on the making of fine violins, it has a good-deal to recommend it. Pictures by the author are in near-caricature style, with a good deal of humor. Reproduced in color and line.
