Apparently Jack was as intent upon settling the question as Amos himself could be. He put on more speed, and side by side they broke into a run, such was their eagerness to cover the intervening ground. Men in khaki looked after them in bewilderment, not knowing who these two boys were, or what object they could have in thus braving the fearful ordeals to be encountered on a battlefield. Amos was caring little for all this. He had but one object in view, and that the settling of the question whether his long absent brother Frank, now one of the Allies’ aviators, was working on that section of the firing line, and if he was fated to meet him face to face after so arduous a search. Whether Amos and his faithful chum Jack were to be rewarded with immediate success after their eventful hunt for the missing Frank, or meet with still further disappointment, must, however, be left to another story, which the reader will find ready for his perusal later on. THE END. * * * * * BOY AVIATORS’ SERIES By Captain Wilbur Lawton Absolutely Modern Stories for Boys Cloth Bound Price, 50c per volume The Boy Aviators in Nicaragua Or, Leagued With Insurgents The launching of this Twentieth Century series marks the inauguration of a new era in boys’ books--the “wonders of modern science” epoch. Frank and Harry Chester, the BOY AVIATORS, are the heroes of this exciting, red-blooded tale of adventure by air and land in the turbulent Central American republic. The two brothers with their $10,000 prize aeroplane, the GOLDEN EAGLE, rescue a chum from death in the clutches of the Nicaraguans, discover a lost treasure valley of the ancient Toltec race, and in so doing almost lose their own lives in the Abyss of the White Serpents, and have many other exciting experiences, including being blown far out to sea in their air-skimmer in a tropical storm. It would be unfair to divulge the part that wireless plays in rescuing them from their predicament. In a brand new field of fiction for boys, the Chester brothers and their aeroplane seem destined to fill a top-notch place. These books are technically correct, wholesomely thrilling and geared up to third speed. Sold by Booksellers Everywhere HURST & CO.
