RADIO WILL GUIDE ZR-3 ACROSS OCEAN TO HELP GIANT ZEPPELIN ON 3,600-MILE TRIP Giant German-Built Craft to Be Protected on Flight by Weather Broadcasts By Carl H. Batman WASHINGTON.— Early in November it is expected that the Zeppelin Company will point the nose of the great ZR-3 toward the West and the long overseas journey of the navy's second airship will begin. On her maiden trip to her American home at Lakehurst, N. J., a distance of approximately 3,600. nautical miles, Radio will guide this latest Zeppelin. She will not be under Radio control, as was the old battleship "Iowa" when sunk by naval gunfire, but Radio will carry to her twice daily complete forecasts of the weather ahead and the meteorological conditions on the southern trans-Atlantic steamship route along which, it is understood, she will proceed under the direction of the German officers and crew. The only American officer who is certain of making the trip over is Capt. G. W. Steele, U. S. N., her future commander. Description of Giant Craft Briefly, the characteristics of the new aerial passenger cruiser (she is not a war craft, at least not yet) are: Length 660 feet, slightly less than the American built ZR-1; diameter, 90 feet; power, four 40fr horsepower Maybach engines, giving a speed of approximately 80 miles per hour. Through arrangements between the weather bureau, navy, shipping board vessels and certain other north Atlantic ships, meteorological data from all along the ZR-3's route will be compiled and Radioed twice a day to a station ship in mid-Atlantic. This vessel will have a powerful Radio set and will transmit to NAA, Arlington, Va., bulletins for broadcasting to the ZR-3, both before and during her flight. Little is known of the Radio equipment of the ZR-3, but it is said that it is also of the latest German type, and that transmission and reception are assured all the way across the Atlantic, although half that range would be sufficient, due to the cooperation of the station ship and NAA. STOPS PROGRAM TO AID GROUNDED SHIP WJAZ Picks Up Distress Call of Stranded Vessel in Lake Michigan CHICAGO. — For the first time in the history of Great Lakes navigation a broadcasting station came to the rescue of a distressed steamship, when Station WJAZ, the Edgewater Beach hotel, recently picked up the SOS call of the Canadian Adventurer off the harbor of South Chicago. While the program of the broadcasting station was being given, one of the receiving sets, equipped with a wave trap for the reception of signals on a different wave length than that used by the broadcasting station, picked up the distress signal. R. H. G. Mathews, manager of the central division of the American Radio Relay league, and one of the owners of Station WJAZ, ordered the program stopped and took down the following message: "SOS. Send tug to Canadian Adventurer, aground outside South Chicago pier." Mr. Mathews communicated with the ship and learned that the operator had been frantically endeavoring to rouse the Great Lakes station. He then phoned the Dunham Towing company, which at once dispatched tugs to pull the vessel off the shoal. The craft was not damaged. FRANCE AND AMERICA STANDARDIZE WAVES Compare Frequencies Used in Trans-Atlantic Communication New Service for Lake Shipping WASHINGTON, D. C. — Weather bulletins and hydrographic information are being broadcast twice daily by the Intercity Radio Company, located in Cleveland, on Lake Erie. The service is intended for the shipping on the Great Lakes, and will be broadcast on a wave length of 706 meters, spark. The call of the station is WTK. This station also is licensed to communicate with Rogers City, Mich., on a wave of 1,764 meters. WASHINGTON. — In an effort to standardize Radio frequencies used in transAtlantic communication, the Navy Department is co-operating with the French Government and once a month the frequencies of the Annapolis and Lafayette Radio stations are recorded and compared. Transmission on standard frequencies, or wave lengths, is essential to efficient communication in order that all stations can keep to the wave length assigned them by national or international law. Special efforts are now being made by the United States and foreign governments to keep all their stations on the prescribed waves and it is essential that their standards be equivalent and their instruments be calibrated. When all stations maintain their proper wave lengths or frequencies exactly, tuning in will be more readily accomplished, it is pointed out, the process approaching the simple adjustment of a dial to a known position. Perhaps dials will be marked "London," "Paris," "Berlin," etc.. in the future. John Osborn, well-known Philadelphian, attracted considerable attention recently by appearing on the Fairmount Park bridle path wearing a complete portable Radio set with a loop aerial on his back. By B. B. Leibner Radio has been stumped at last. The greatest wonder of the age, which has cut down space, helped cure the sick at sea and on land; which has made many of the deaf to hear, and which could have sent the latest baseball scores and live news into the heathen lands, had the people there been sufficiently interested, has encountered its first, apparently insurmountable obstacle in the massive form of an elephant in captivity. The waves that have carried almost every known sound through the air, as well as many sounds and squeaks and speeches hitherto unknown, have finally cracked under the strain of the elephant language. And Syed Ali, native Indian mahout, nurse and companion of Indarini, the prize elephant of the London Zoo, has lost all faith in modern methods and contraptions. Inherit Elephant Bingo It seems that for centuries and centuries, dating back into the dim mists of the beginnings of time, the Indian mahouts, keepers and trainers of elephants, have inherited, son from father, an elephant language that all the huge pachyderms heed, understand and obey. The principal commands in this "Hathi ki Bat" — "Tongue of the Elephants"—are: Eat your hay! Drink the water! Get up! Lie down! Pick it up! Pull! Stop that noise! "Indarini is a smart elephant," said Syed Ali, the London keeper, to himself, "but not quite up-to-date. I'll have to teach him some of the new ways." Ali Becides to Broadcast So Ali dressed himself in state clothes, with crimson headdress and all, and went to a broadcasting station four miles away from the Zoo. He was going to give his orders to Indarini, the elephant, in the way of 1923 — by Radio. Arriving at the station, Syed Ali sent out his commands. From the attendants, who remained at the Zoo to watch the developments, he soon received reports by telephone, regarding the outcome of his experiment. Did Indarini obey the commands? He did not. Indarini Says, "Nothing' Doing" Did he heed his master's voice? Nothing doing on that score. After several attempts, Ali gave up the attempt in disgust. For instead of following the commands of his master, the elephant went on calmly munching the apples, potatoes and locust beans that the London kids, visiting the Zoo, offered him. Zoologists now believe that elephants will not obey a disembodied voice. These animals apparently must see and smell their master — and they can't do that by Radio — yet. And that presents an opportunity for some ambitious, far-seeing and ingenious inventor to carve his name in the hall of fame. Queen Alexandra returned thanks to the British people for their greeting on the sixtieth anniversary of her wedding day by broadcasting. The "B" Battery is the Life of Your Radio Set THIS IS NUMBER ONE OF A SERIES THE only function of your Radio set is to produce sound-waves — those mechanical disturbances in the air caused by some rapidly vibrating body. So far as the Radio set itself is concerned the actual source of the sound is the "B" Battery. It is not an exaggeration to say that the "B" battery is the "life of your Radio"; for the set itself is simply a device to reproduce sounds, and the sounds all have their origin in the "B" Battery. The "B" Battery is simply a box full of electrical energy; harnessed for you by experts. Without the Radio wave the flow of energy from the "B" battery is smooth, steady and silent. It is the final aim and purpose of all the many parts which go to make up a Radio receiving set, to convert the otherwise steady flow of electrical energy from the "B" Battery, into a rippling, vibrating, throbbing, audible current. As the sound-waves — whether caused by the human voice in talking or singing, or by musical instruments — are modulated up and down — now high — now low; so does the current from the strongly vital "B" Battery follow the modulations and the variations, so that the original message, in all its delicacy of tone and vibration, comes clear imd distinct through your Radio set. Not a mere adjunct to the pleasuregiving quality of your Radio set is the "B" Battery — instead, it is the vital, life-giving part — the very heart of your Radio set. Do not slight this vital part — give your Radio set the advantage of the best — use Eveready "B" Batteries.
