I COInpduy,
 MT. Ellsworth said, ''that the long dis tance tests to San Francisco and l Hawaii were conducted entirely by | the conpany's engineers. The navy's representatives courteousIy loaned the use of their towers and were inter ested observers. But they were only observers. They did not conduct the 1 test
 "It is not so that ony of pr. De Forests patents were used. As MT. 1 Gherardi pointed out, all the new ap- | pliances were the discoveries of the company's own engineers. The com pany will not enter into any controz i versy with pr. De Forest, who on other occasions has sought publicity l by claiming successes which belong ed to the A. T. and T. alone"
 An effort was made to reach pr. De Forest by telephone in his home at Spuyten Duyvi1 without success.
 Last night Secretary Daniels had not yet received any letter from Dr. FDe Forest and all the naval officers say the departments only share in l the tests was to lend the towers and 1 to observe what, was done.
 The wireless talk to Hawaii was conducted under circumstances which on the receiving end, at least
 might have been better The receiv- I ing antennae were not strung very high, nor were they elaborately pre- pared. They were stretched between 1 a smokestack and a watertower and were not nearly as high as the Arling-. ton Tower. MT. Espenchied was sent to Hawaii several months ago to pre- pare for the test, which was a we'll kept secret until it had been accom- plished.
 ITO Chief Engineer John ;. Carty is given most of the credit for it's conplishment, and President Vail, in a formal statement warmly congrat- l ulated him and his staff. Hundreds of electrical experts both in the pe- search and manufacturing lines took part. MT. Gherardi put it thus: eff one is asked, Who won the battle 2 the reply is. The General and his soldiers In this case Carty was the General and we were his army
 Carty Telephone Pioneer MT. Carty is fifty-feur years old, a native of Cambridge, Mass. and pioneer in telephone, having been in I it since 1879. He possesses >the Order of the Rising Sun, conferred upon him by the Emperor of Japan, and is a member of many scientific bodies. MT. Gherardi was asked if he would endea6or to give an explanation, free fo technicalities, of the new system. 'F.or various reasons cannot he said. "In the first place, we are not yet. protected by patents. We have taken the necessary steps along that line. but the Patent Office moves slowly. Then, again, it would take
 me a week, I believe, to put the mat ter into untechnical words which a 1ayman might understand. There have been Inventions and discoveries of a. scientific nature which only the most skilled scientists could compre- hend.',
 Have any principles been learned which never were known before?'' he was asked.
 ''Yes that has been the case. Some things entirely new have fbeen dis greatly developed and improved. may say this much: There have been great developne eIlts affecting the transmitting apparatus, and also af fecting the receiving apparatus.
 Our success has been gained ! through these things: First, the ar rangeInent connecting the wire tele- phone with the wireless system at the towers; second, a special apparatus for transmitting the speech from the tower into the other;s third, the con- nection which receives the voice from the ether at the receiving tower, and, fourth, the connection which puts the voice back on the wire again.
 '"The new appliances are all at the towers. So far as the original send ing of the voice goes, and so far as the final receiving of the conversation i & ment now in use is perfectly satisfac- tory"
 Some Natural Drawbacks.
 MT. Gherardi repeated what had been said the previous day, that the wireless telephone had certain natural drawbacks that will prevent it from ever displacing the wire te1e- phone. But it will beautifully sup p1ement the wire system and be of +o ind h S9id
 There are three difficulties about wireless telephoning." he explained. ttOne is tstatic,' that mysterious dis turbance in the atmosphere. Anoth- CT is the interference of other sta tions. There's only one ether to work in, and with many stations working there is bound to be conflict, though tuning will help to remedy that.
 '.The third trouble is that there can be no secrecy. Y You're literally shout ing out to the whole world when 1 you talk by wireless phone, and any one can tune a receiving instrument so as-to hear you.
 ''But for reaching ships at sea and ina accessible points on land. and, in fact, for reaching places where wires can't reach, believe this system will be of incaIcu1ab1e value. am not a, military of naval expert. but be- lieve that both arms of the service can make great use of the wireless telephone.
 Conversation from ship to ship should be easy. In the suppositious case of an enemy destroying all the land wires in the United States, or ders might be issued from Washing ton or New York, from any tall tower, to any point within the boundaries of the country
 Experiments Cover Several Years.
 The experiments Of Engineer Carty and his adies have been going on, MT. Gherardi said, for several years. Early this year they talked from an experimenting tower at Montauk Point to a privately owned tower at Wilmington, Del, a distance Of 25O miles. Soon aftrward they talked 1rnrn Monfaulz Point to a fower at
