NAVY DAY PROGRAM 10 BE BROADCAST Radio Hook-Up to Blanket Country for Observance Thursday. Featured by a radio hook-up that will blanket the ited States, the program for the Nation-wide observ ance of Nav, completed by the Navy League of the United States. Not since the inception of the idea of thus observing the birthday President Theodore Roosevelt, fore- most _advocate of the impo.tance of sea power -to the Nation's growth in influence and prosperity, have the ar- rangements for the annual event been as inclusive and comprehensive as this year. In 43 States prominent leaders in official ‘and civil life have agreed to act as chajrmen and have organiza- tions at work to carry the message of the /day to every town and ham let. Iy.the other States, in which the chairmen have not sent formal ac- ceptances of their willingness to serve, other agencies, patriotic so- cieties,sreserve units and individuals are carrying on. Sea Power and Commerce Talks. Virtually every port in the country will be the home port on that day for one or more naval vessels and open house will be order of the day aboard all ships and all the Navy's shore stations. Visitors will be welcomed and shown the sights under the guid- ance of naval personnel. The keynote of tbe speeches made throughout the country will be “Sea- power and Commerce,” stressing the importance of the merchant marine, primarily its vital importance to the economic life of the country and its bearing on national prosperity. and of its potential use as an invaluable adjunct to the fleet in time of war. Special attention will be called to the three fundamentals of sea power, foreign trade, merchant marine and naval protection. Program Centers in Capital. Centering in Washington, the radio program will be broadcast over both the Red and Blue chain of the Na- tional Broadcasting Co. Three speak- ers are scheduled—Secretary Wilbur, Rear Admiral H. P. Jones and Comdr. Richard E. Byrd. A musical program also. will be given which will include selections by the Navy Band Orches- tra.~ Another feature will be the first appearance before the “mike” of the double ‘quartet from the Naval Acad- emy in two groups of songs. HOLLAND PROGRAM HEARD IN CAPITAL Delegate to Conference Sets Up Short-Wave Receiver to Show Potentialities. . Potentialities of long-distance broad- ecasting have been forcibly demon-| strated to Americans not only by the Marconi beam system, which in its gresent stage uses only a code signal, ut by a short wave system perfected by the Dutch for transmitting pro- grams to the far-flung colonies of Holland. Dr. Balth van der Pool, a delegate to the InternatioméiRadiotelegraph Conference now me in Washing- ton, last week set up @ special short ‘wave receiver @t the Bereau of Stand- ards and pickéd up a program .broad- cast by station’ PCJJ, at Eindhovenk, Holland, & Wn‘ which he had de- signed and Dr.“van-der Péol, who is director of research for the Philip’s Radio Works, which operates under a concession from the Dutch government, set up the specially devised Phillip’s appar- atus with the assistance of Dr. J. H. Dellinger of the Bereau of Standards, and together they listened in on a program of speech and music which they heard very clearly. The program was being broadcast on a wave length of 30.2 meters,and was_being transmitted especially for the Dutch colonies of Java and Dutch Guiana. For at least six months, Dr. van der Pool said, these experimental broadcasts have been received with more or less regularity in the colonies. At one time Queen Wilhelmina spoke into the microphone on the short wave,| broadcast to the colonies. This is be- lieved to have been the first time any. monarch ever directly addressed subjects so far away. ‘The success of this system of broad- casting has Jed to the formation of a ¢ompany “Which will furnish pro- regularly to the colonies.

OCEAN PLANE MODEL ARRIVES IN AMERICA Levine Machine for Oversea Serv- ice to Weigh 40 Tons ‘With Seven Motors. By the Associated Tress. NEW YORK, October 32.—A wind- tunnel model of the giant, 40-ton, meven-motored “fing wing” plane from which Charles A. Levine expects to bulld up a regular transatlantic service within a year, arrived yester- day from Europe in the possession of Levine’s associates. ‘The new machine will house passen- gers in the large main wing instead of in the fuselage. Of the seven 800- horsepower motors two are to remain idle except in case of accident, when they may be switched on to prevent the plane from falling. The plane, resembling a greatly en- larged monoplane, will have a wing spread of 180 feet. The wing will be nine feet thick in the center section which will be used for passenger commodation. ‘The wooden model of the plane will be used in wind-tunnel tests to deter- mine the machine’s resistance to the air. The two engineers who brought the model and who Levine has said were to develop the new plane are Alexan- der Kartvelichvili, a Russian expatriate living in Paris, and Edmund Chagn- jard, a French aeronautical engineer. ‘With them were Maurice Frankel, Le- vine's business manager while he was abroad, and John Carisi, his motor expert. HOME OF NEEDLES. New England Makes Most Sewing Accessories. Correspondence of the Associated Press. BOSTON.—New England has just discovered that it makes three-fourths of the tiny clothing accessories used by women in the United States— of such as needles and pins, hooks and | eyes, and snap fasteners.

Compensation is a rule that works both ways. Broadcasters have overcome a num- ber of difficulties for radio owners through increasing power. There is less fading to contend with and radio- ists are enabled to enjoy good recep- tion even if their batteries or tubes are not in the best of condition. There are, however, numerous instances where broadcasting is not at its best, and where this is the case the radio owner should look to the facilities of- fered by his own set and its acces- sories to overcome the difficulties. He can soften reception through de- tuning. This is a simple process of turning the tuning dials a little off the true setting for the respective station, and is a plan which many radioists know about, but often overlook. If there is too much volume he is able to cut out a stage of audio and thus re- duce the amplification. It is not generally recognized by radio owners that even though a broadcaster may take special precau- tions to have everything in the most satisfactory order, there are many fac- tors beyond his immediate control. Weather conditions may be adverse to radio broadcasting in the territory near the studio, yet out where some set owner is getting signals the air may be cool and crisp. It is not possible for the broadcaster to meet all conditions where they change so ra; and where the spread of the signals. is so extensive. 5 the Job is left to the radioist who has within his power equipment and con- trols sufficient to enable him te adjust the sensitivity of the set to meet the efficiency of signal transmission. Radio Waves Penetrate Rock. Recent tests, conducted by the Bureau of Mines in a Colorado metal mine, indicate that radlo waves will penetrate 500 feet or more of rock strata. Preliminary experiments were observed by Dr. A. S. Eve, director of physics at McGill University, Mon- treal, Canada, who is conducting a study for the bureau of the possibil- fties of various methods of geophysical prospecting for the location of mineral deposits. The experiments participated in were carried out wtih a superhetero- dyne receiver of nine tubes in the mine of the American Mining & Pros- pecting Co., at Caribou, Colo. The first test was at a depth of 220 feet, where, by means of a loop, a strong and clear reception was obtained of a musical concert broadcast by a Denver station, 50 miles distant. The evidence pointed strongly to the conclusion that this clear reception was due to the penetration by the radio waves of the solid rock strata, although there was a remote possibility that the reception was obtained through shafts and cross-cuts, although the loop did not point in that direction. The nearest metal conductors, iron rails, were 6( feet away. The next experiments were con- ducted at a depth of 550 feet, when “mushy” reception was obtained from the Denver transmitter. This type of reception was, however, as good as could be obtained above ground at the time, the night being unfavorable. This series of tests was conducted at the end of a cross-cut reached after many turns, and 200 feet from the main shaft. A pipe came down the shaft and followed the tunnel up to 80 feet from the point of observation. Following previous experiments con- ducted by the Bureau of Mines near Pittsburgh, Pa., it was at first con- cluded that radiation and induction would penetrate rock for considerable depths, but subsequent investigations showed that in every case the trans. ference of radiation was by some con- ductors such as electric wires, pipes or rafls. It is possible that at Carlbou the radio waves excited the conductors ir the shaft. and that these In turn excited the ralls and pipes, which brought the radiation to within 70 or 80 feet of the experimenters, and that E K.

RADIO GOSSIP AND NEWS the strong amplification of the radlo apparatus enabled the _radiation bridge the gap. Dr. Eve cons. this is improbable, but not impossible. He was impressed with the fact that the loop did not point toward neigh boring conductors or along the tun- nels, but that it did point at both observation levels within a few de- grees of the source at Denver. The evidence is strong, but not absolutely conclusive, that wireless waves will penetrate 500 feet of rock to an extent which enables them to be recefved with powerful amplifica- tion. It is desirable, the bureau experts hold, that these investigations should be followed by further research work on the subjedt. Through Time With Tubes. Among all the features of radlo, perhaps the development of the vacuum tube is the most interesting. For the sake of those who like to go back into history, and who feel that it would be interesting to know the evo- lution of the invention of the present- day vacuum tube, the following chron- icle may be of value: The first electric light was developed by Sir Humphrey Davy. That was 117 years ago. Later Thomas A. Edison discovered what is known as the Edison effect. Quite a number of years later Prof. Fleming, an Englishman, utilized the Edison_effect in detecting radio sig- nals. His detector tube at that time was called the Fleming valve. Later Dr. Lee DeForest added the grid, the third member in the vacuum tube. Since then there have been numerous _refinements, Dr. Irving Langmuir, an American, being on$ of the chief contributors to the present- day tube. i e French Wine Harvest. - The provisional estimate .of the wine harvest of France this year is that it will amount to between 1,056,000,000 and 1,100,000,000 gallons, which is higher than last year's har- vest, but below the average. — The jury system will be put into :grz'(ée in Japan beginning October 1, BROADCASTING GROWS. 35,000 Hours of Broadcasting Of- fered During September. Statistics cited by George H. Kiley, radio manufacturer, indicate the ex- tent of the growth of program broad- casting in the United States. Mr. Kiley estimates that during Septem- ber alone American radio listeners had 35,000 hours of radio entertain- ment offered by the 700 broadcasting stations in this country. No listener with even a single tube et could get less than 2,000 of these hours, no matter where he was situated—that is, he had that amount of entertainment available to him, al- though, of course, he could not spend that much time listening, says Kiley.
