-RADIO BROADCAST ADVERTISER. A Simplified "MORECROFT" Elements of Radio Communication By JOHN H. MORECROFT Professor of Electrical Engineering, Columbia University For several years Morecroft's "Prin- ciples of Radio Communication" has been recognized as the last word on the subject. But as it is highly tech- nical, there have been many sugges- tions to the effect that a similar but shorter and simplified work would be welcomed by thousands of people. In response to this, Professor More- croft has just written "Elements of Radio Communication." It embraces all the major features of the larger work,'but it is treated in a much simpler fashion. While technical, it requires no mathematical training further than a knowledge of elementary algebra. The whole field of radio is discussed from broadcasting to receiv- ing, and the latter from a simple crystal set to the most modern A.C. operated receiver. Also, the book is completely illustrated with charts and diagrams, and is supplemented with sets of problems taken from actual radio circuits and apparatus.

The company has found that customers appreciate frankness in these respects. When a new man is hired, Mr. Moore instructs him clearly and concisely with regard to the firm's policies. There is none of this "turning a man loose" to do as he pleases and in his own fashion. Whenever a new model appears—and at any other time there may r>e occasion for it—a sales meeting is held. The features of the sets are pointed out one by one and Mr. Moore shows how they should be sold. Representatives of manufacturers and wholesalers are also asked to talk before these meetings occasionally as one of the best means of keeping the Universal sales- men strictly up to the minute. Highly important in the handling of salesmen, says Mr. Moore, is in giving them a real incentive to put forth their best efforts. He believes that the commis- sion method of paying men offers the best solution—providing the dealer's responsi- bility in the men does not cease with the mere offer of payment in case they pro- duce. Hence, Universal salesmen are paid 10 per cent, commission on sales against a drawing account of $40 a week. They also receive carfare for their work. There is another important factor about Mr. Moore's method of paying his men. Fifteen per cent, of every 10 per cent, commission is held back by the company for three months until a fund of $100 has been created in the salesman's favor. This has proved an effective and adequate guarantee against forced sales on the in- stalment plan where the customer's re- luctance to meet payments might not be discovered for several months. The Universal Radio Company wants its men to feel a direct responsibility in every sale they make. It is not taken for granted that salesmen call back at the home of every customer after sets have been in operation a couple of weeks, re- ports being necessary in every instance. This practice pleases the customer, in- sures successful operation of sets and re- sults in obtaining new prospects. ROBERT S.
