THE BOY INVENTORS' DIVING TORPEDO BOAT.
As in the previous stories of the Boy Inventors, new and interesting triumphs of mechanism are produced which become immediately valuable, and the stage for their proving and testing is again the water. On the surface and below it, the boys have jolly, contagious fun, and the story of their serious, purposeful inventions challenge the reader's deepest attention.
