This is a story of active boys of fifteen or so. They are very fortunate in the friendship of the principal of their school and his friend, an athletic young doctor. Under the care of these two they go into camp on an island well suited to the purpose, and within easy distance of a thronged summer resort. A series of exciting ball games and athletic contests with the boys at the hotel naturally follows, and the boys display as many varieties of human nature as could their elders. The author is a man who knows boys thoroughly, and by his work is known to a very large number of them, and the whole atmosphere of the story is merry, wholesome, and just what boys like. "Mr. Eldred's book is almost certain to meet with a ready response from young readers, for not only are the boys filled with life and vigor of a true youthful and appreciable variety but their experiences are entertaining in themselves and may perhaps give the young readers ideas for summer plans of their own."--Chicago Tribune. "This is a capital book for active boys, vigorous, wholesome and sane, written by a man who knows boys and can give them the best kind of vacation."--Defender, Boston.
