What Happens When You Mail a Letter
By Herbert O. Johansen
With the Christmas rush on, the complex network of men and machines that speeds the mails is working in high gear.

Torture Tests Tell The Truth

EVERY time you visit the dentist, break in a pair of new shoes, buy an electric light bulb, heat your home, drive an automobile, wind your watch or weigh your groceries, you are directly or indirectly affected by the work of scientists located in an enormous network of laboratories in an obscure section of Washington, D. C. This is the National Bureau of Standards, where a group of technical men seem to live in a complicated mechanical world that appears far afield from that of Mr. Average American Citizen. This Bureau of Standards, without the slightest exaggeration, is the nation’s and probably the world’s, greatest quality testing laboratory. Every day, in almost every conceivable way, it performs monumental tasks which help make life healthier, safer, happier, more comfortable and more convenient for every one of us.
