Price, 50c. per vol., postpaid THE BOY INVENTORS' WIRELESS TELEGRAPH. Blest with natural curiosity,--sometimes called the instinct of investigation,--favored with golden opportunity, and gifted with creative ability, the Boy Inventors meet emergencies and contrive mechanical wonders that interest and convince the reader because they always "work" when put to the test. THE BOY INVENTORS' VANISHING GUN. A thought, a belief, an experiment; discouragement, hope, effort and final success--this is the history of many an invention; a history in which excitement, competition, danger, despair and persistence figure. This merely suggests the circumstances which draw the daring Boy Inventors into strange experiences and startling adventures, and which demonstrate the practical use of their vanishing gun. 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.
