This book relates the further adventures of the young Americans in France, where they viewed the fighting from above the firing lines. From this book the reader gains considerable knowledge of the different types of air planes and battle planes used by the warring nations, as all descriptions are illustrated with unusually clear line drawings. =The Boy Volunteers with the British Artillery= How many boys today know anything about the great guns now being used on so many European battle fronts? Our young friends had the rare opportunity of witnessing, at first hand, a number of these terrific duels, and the story which is most fascinatingly told is illustrated with numerous drawings of the British, French and German field pieces. =The Boy Volunteers with the Submarine Fleet= Our young heroes little expected to be favored with so rare an experience as a trip under the sea in one of the great submarines. In this book the author accurately describes the submarine in action, and the many interesting features of this efficient fighting craft are made clear to the reader by a series of splendid line drawings. =The Boy Volunteers with the American Infantry= The entry of the United States into the great conflict offers the two boys their long-looked-for opportunity. The arrival of our troops abroad and the boys' experiences with them make a thrilling tale.
