THE RAILROAD SERIES

By ALLEN CHAPMAN
Author of the “Radio Boys,” Etc.

Uniform Style of Binding. Illustrated.
Every Volume Complete in Itself.

In this line of books there is revealed the whole workings of a great American railroad system. There are adventures in abundance—railroad wrecks, dashes through forest fires, the pursuit of a “wildcat” locomotive, the disappearance of a pay car with a large sum of money on board—but there is much more than this—the intense rivalry among railroads and railroad men, the working out of running schedules, the getting through “on time” in spite of all obstacles, and the manipulation of railroad securities by evil men who wish to rule or ruin.

THE RIDDLE CLUB BOOKS

By ALICE DALE HARDY

Individual Colored Wrappers. Attractively Illustrated.
Every Volume Complete in Itself.

Here is as ingenious a series of books for little folks as has ever appeared since “Alice in Wonderland.” The idea of the Riddle books is a little group of children—three girls and three boys decide to form a riddle club. Each book is full of the adventures and doings of these six youngsters, but as an added attraction each book is filled with a lot of the best riddles you ever heard.
