Modern Geography has stood the test of use. It is in successful use in hundreds of schools under widely varying conditions. It is as successful in the manufacturing district around Pittsburgh as in the agricultural state of Iowa. It has been adopted for exclusive use in the state of Kentucky as well as in nearly all the high schools in the city of Chicago.

J. R. HOATS, Stadium High School, Tacoma, Wash.

We are using Modern Geography in one of our courses and like it very much.

R. A. DARTEN, Carlisle, Pa.

I used Modern Geography last term and found it very satisfactory. W. LEO HARRINGTON, East High School, Des Moines, Iowa.

I have had the pleasure of using Modern Geography in my classes and I desire to say the following: It interests more than any book I have ever used. It is complete. It is easily used by both pupil and teacher. What more is there to say?

EVER SO LONG AGO in faraway India, stood the "Tree of the Sun;" its top a widespreading garden wherein stood a "Castle of Crystal" with view toward every quarter of the Heavens. Below in the castle walls were reflected pictures of the world, representing all that took place each day. Here dwelt a beautiful blind maiden who had spun a wondrous thread by which she might be guided home again, when she should fare forth into the great world. This thread not being visible to mortal eyes, the way to the Sun Tree was long ago forgotten-BUT now 21 skilled workmen have woven a cable-600 strands strong, and christened it the KEYSTONE "SIX HUNDRED SET."

Holding fast to this visible "Teachers' Guide," the boys and girls of our schools DAILY may wend their way to this Palace of Pictures, the mystic mirrors of whose walls reflect TENFOLD the wonders of its 600 views.

THREE UNUSUAL NEW MAPS

Each Distinctive in its Class

Chamberlin's Map of North America
During the Great Ice Age

By Professor Thomas C. Chamberlin, Head of the Department of
Geology in the University of Chicago.

By the world authority on glaciation, this map is the most complete expression on the subject, and the only large scale map of its kind. On a black base map it shows, in a solid tint of light blue the maximum extent of the great ice flow, and at the same time, by hundreds of dark blue arrows, it points the movement of the glacier. Terminal moraines are indicated, and a white patch on the blue expanse locates the "driftless" area of Wisconsin and the adjacent states.

Size 46 x 66 inches. Hand mounted.

Van Cleef's Rainfall Map of the United States

By Eugene C. Van Cleef, Professor of Geography, Normal School, Duluth, Minn. (In preparation).

A complete, accurate, and scientific wall map of the normal annual rainfall in the United States, based upon the most recent bulletins of the United States Weather Bureau. Topographic influences are well pictured. The variety of the mountain regions, and the simplicity on the plains are shown with an accuracy and detail not seen in the ordinary rainfall map.

"We have long needed such a map," writes Professor DeC. Ward, Harvard University.

Size 46 x 66 inches. Hand mounted.

South America

Goode Political Series of Wall Maps.

Built on the latest data, and portraying a continent whose very name spells a magnificent future, the map is wonderfully interesting. With the Caribbean Sea, the Gulf of Mexico, and the Panama canal included, the great steamship lines are fully pictured bespeaking interAmerican as well as European relations, and focusing at our new gateway, they voice a promise beyond our power to vision. On this map Colonel Roosevelt traced with his own hand the "River of Doubt," the Rio Theodoro.

Size 46 x 66. Hand mounted.

All these maps are printed in colors.
