Mr. William A. Nash of Biddleford, Me., writes to us that the article “Pictured Electro-magnetic Waves" in the December issue of “QST” is not exactly clear to him. He asks these questions: 1. What is meant by having the lead at the higher end of the aerial. 2. As shown in the sketch, which is the more efficient arrangement, Fig. 1 or Fig. 2? 3. Just when are the signals received strongest between two stations? When the aerials are pointed toward each other or away from each other? 4. In sketch No. 1 aerial B transmitting, are the stronger signals toward the east or west? Ans. 1. If in the aerial proper, one end is higher than the other and the lead-in is connected to either end, we speak of the lead as being connected to either the high or low end, as the case may be.

Up to October first I had a small station and had been working on the various parts necessary to the construction of a one Kw. stations, however, on that date I moved my residence and am now living next door to the telephone exchange in this city. My move put me out of business from a wireless standpoint. The Telephone Company has continuously running a small rotary converter, ¼ H.P., 16 cycle, 80 volt, for the purpose of converting the city’s 110 volt lighting current into their direct ringing current. In my previous location (about a block from the exchange) I could hear this machine but not loud enough to annoy me seriously; however, since moving next door am unable to drown out or tune out the loud singing noise made in my receivers by this machine, and for this reason have had to abandon my wireless altogether. Can you suggest a remedy by which I might get rid of this singing noise without

Ans. 2. With A and B communicating the arrangement shown in Fig. 2 would be the more efficient. Ans. 3. The signals will be stronger in case two. This is purely a theoretical case; in practice trees, houses, telephone lines, and all objects would affect the waves. Even in theory the difference might not be very marked, perhaps three or four percent, depending upon the conditions. Ans. 4. In Fig. 1 B transmitting the signals are stronger toward the East. E-East. W-West.

Dec. 17, 1915. Mr. C. D. Tuska, Hartford, Conn. Dear Sir: Enclosed please find 25 cents for “QST” as per December issue. In answer to K. Kathkan’s query permit me to say that it has been suggested that Mr. K. being a Japanese has no business to ask such a question that upsets the laws of our society. Have enclosed application blank for A. R. R. L. May I suggest that it be obligatory on the part of special license stations to have
