This is a pioneer book. It ranks with books on interior decoration and

furniture as a help toward transforming a house into a home. It is

practical in that it offers advice on all sorts of lighting problems and

it is fascinating reading as well.

ARTIFICIAL LIGHT, ITS INFLUENCE ON CIVILIZATION

6 x 9, illustrated, 366 pages $3.00

This story of the achievements of artificial light is written especially

for the man in the street who is not interested in technical scientific

terms and formulae, but who looks with admiration upon the huge signs

which flash and sparkle above the crowds on the Great White Way, who

marvels at the colors and brilliance of a spectacular theatrical

production and desires to know how it is accomplished, and who takes a

natural delight in hearing about scientific discoveries when they are

explained in the simple, vivid language he understands best.

THE LIGHTING ART, ITS PRACTICE AND POSSIBILITIES

6 x 9, illustrated, 229 pages $2.50

This book discusses lighting as engineering plus art, and treats the

subject as a branch of interior and exterior decoration. The technical

aspect of the subject is not neglected, but the main emphasis is upon the

"why" and not merely the "how" of lighting.

THE LANGUAGE OF COLOR

6 x 9, illustrated, 282 pages $2.00

A practical volume on color, the various fields in which it is used and

its importance in portraying the ideas that make for progress. A book of

special interest to all those who deal in color schemes and values.

THE BOOK OF THE SKY

6 x 9, illustrated, 236 pages $3.50

"The beauties, wonders, awesome spectacles, inspiring panoramas, and

extensive ranges of vision which await the aerial traveler, make of

cloudland a veritable fairyland if he will open his consciousness to them.

Aircraft have brought this new world of experiences within easy reach of

mankind and it is one of the aims of this volume to awaken those who fly,

or would fly, to the variety of interest which air travel affords."
