Even in a quiet Ohio town remarkable things may sometimes happen calculated to create the most intense excitement. The five motorcycle boys were put in touch with just such an event through a message that came to their wireless station while many miles away from home. What that "voice from the air" told them, and how gallantly they responded to the call for action, you will be delighted to learn in the third volume of this intensely interesting series.

THE BIG FIVE MOTORCYCLE BOYS ON FLORIDA TRAILS;

or, Adventures Among the Saw Palmetto Crackers.

Once more a kind fortune allows Rod Bradley and his four "happy-go-lucky" comrades a chance to visit new fields. Down in the Land of Sunshine and Oranges the Motorcycle Boys experience some of the most remarkable perils and adventures of their whole career. The writer spent many years along the far-famed Indian River, and he has drawn upon his vast knowledge of the country in describing what befell the chums there. If there could be any choice, then this book is certainly the best of the whole series; and you will put it down with regret, only hoping to meet these favorite characters again in new fields.
