The Service of an Electrical

Research Laboratory

The research facilities of the General Electric Company are an asset of world-wide importance, as recent war work so clearly demonstrated.

A most interesting story tells of the devices evolved which substantially aided in solving one of the most pressing problems-the submarine menace. The results attained in radio communication, special X-ray equipment for field hospital service and many other products, for both combatant and industrial use, did their ful! share in securing the victory.

In the G-E laboratories are employed highly trained physicists, chemists, metallurgists and engineers-experts of international reputation. These men are working not only to convert the resources of Nature to be of service to man, but to increase the usefulness of electricity in every line of endeavor.

Scientific research works hand in hand with the development of new devices, more efficient apparatus and process of manufacture. It leads to the discovery of better materials, which ultimately make happier and more livable the life of all mankind.

THRIFT

By Dr. Frank Crane

Tis a common mistake to

IT

suppose that thrift means only saving money. Thrift means spending money intelligently as well as saving it. Thrift

simply means that you know

what you are doing, how much you are spending, what you have spent and what you are going to spend. Every person ought to keep strict account of his income and outgo. It is a matter of habit. When you get used to it, it is as easy as shiftlessness. Thrift is the road to

contentment.
