Did you ever stop to think that your employer constantly weighs his men, balancing one

against the other?

of two men, you and another, both equally faithful and energetic, the thing that decides in your favor or against you is training,

The untrained man kicks the beam-weighs light; the trained man outweighs him, always. He must be kept, promoted, pushed ahead.

The International Correspondence Schools are organized to give you the training that makes you indispensable to your employer. During November last year I. C. S. training turned the scale in favor of 337 men, bringing them promotions or increased salaries. It would have been easy for you to have been one of them.

Within the next month hundreds more will be advanced as the result of I. C. S. training. Will you be one of them? You can be, without leaving your home or present work. It makes no difference where you live, what you do, or how little you earn.

Fill out the attached coupon and get the training on your side with which you must always outbalance your competitor.

Secure the added weight with your employer which enables you todemand an advanceand get it.

Facts are facts. You are being weighed every day. Don't be found lvanting! Fill out the coupon at once.
