Dear Boys:

At last I am able to give you the third volume of “The Motor Boys Series,” a line of books relating the doings of several wide-awake lads on wheels, in and around their homes and in foreign lands.
The first volume of this series, called “The Motor Boys,” told how Ned, Bob and Jerry became the proud possessors of motor-cycles, and won several races of importance, including one which gave to them, something that they desired with all their hearts, a big automobile touring car.
