As they went up the ladder and set foot on deck Rivers turned to Roger, who had followed him, with the rest of the party. "We're back, boys," he said, "and you've stuck right to the end. No man could ask finer comrades on the trail," he put his hand on the boy's shoulder; "men, every one of you, and the boy as good a helper as any one could wish to have."

Government Large 12mo Cloth $1.50 per volume "There are no better books for boys than Francis Rolt-Wheeler's 'U. S. Service Series.'"--_Chicago Record-Herald._ THE BOY WITH THE U. S. SURVEY [Illustration] This story describes the thrilling adventures of members of the U. S. Geological Survey, graphically woven into a stirring narrative that both pleases and instructs. The author enjoys an intimate acquaintance with the chiefs of the various bureaus in Washington, and is able to obtain at first hand the material for his books. "There is abundant charm and vigor in the narrative which is sure to please the boy readers and will do much toward stimulating their patriotism by making them alive to the needs of conservation of the vast resources of their country."--_Chicago News._ THE BOY WITH THE U. S. FORESTERS The life of a typical boy is followed in all its adventurous detail--the mighty representative of our country's government, though young in years--a youthful monarch in a vast domain of forest. Replete with information, alive with adventure, and inciting patriotism at every step, this handsome book is one to be instantly appreciated. "It is a fascinating romance of real life in our country, and will prove a great pleasure and inspiration to the boys who read it."--_The Continent, Chicago._ THE BOY WITH THE U. S. CENSUS Through the experiences of a bright American boy, the author shows how the necessary information is gathered. The securing of this often involves hardship and peril, requiring journeys by dog-team in the frozen North and by launch in the alligator-filled Everglades of Florida, while the enumerator whose work lies among the dangerous criminal classes of the greater cities must take his life in his own hands. "Every young man should read this story from cover to cover, thereby getting a clear conception of conditions as they exist to-day, for such knowledge will have a clean, invigorating and healthy influence on the young growing and thinking mind."--_Boston Globe._ THE BOY WITH THE U. S.
