 Emergenoy Telegraph system.
 The feasibility of establishing tele- graph and telephone communication he tween two distant and isolated noipts without constructing an elaborasa sxs. tenn of electric batteries, poles or sess4. dults and wires or resortiup to the complex day heliograph or night flash. Light devices was successfully aeaou- strated on Saturday night at Ba5onpe N. J., by William A. Eddy, the sciep- tiic kite dier of that city.
 The equipment used by Aerolopist Eddy for his emergency telegraph and telephone plant comprised several of his aeroplanes, reel of stout kite cord. n reel of ordinary copper wire, number of common lanterns, two simple tele. phono transmitters and a telegraph sounaer He utilized the ground and atmospheric currents for his electric power MT. Eddy and bis assistants, Henry L Allen of this city and Dr William H. Mitchell of Bayonne, con. trived 10 send and receive perfectly in. i teIligibie vocal telephone messages a, | deeipherable telegraph messages dur q period of several hours from poinss fullyl, 900 feet distant and separated by double that distance of wire.
 The scene of Mir. Eddy's achievements was the Bergen Point section of Bay onne His aeroplanes and the wire they carried were sent up from the open lots in tho rear of his honlS, on East Third street The kites carried and supported the wire over houses, streets, telephone and telegraph poles and wires to the point selected for the dis. tant connection with the earth. Be- tween the two stations thus established 2 ridge of sufficient height to prevent the experinentalists from even signal. ing to one another with ianterna also intervened. This necessitated oue of the trio staiioning himself at an interme- diate point to transmit signals before the aerial circuit was completed.
 Whom the pilot kite attained an aIti- tude of 1, 900 feet the wire and it's low ering device were connected with the kite cord. an eight ounce red lantern designating the place of connection and similar Lightweight green Ian. tern sbeing fastened to the plummet OR tho end of tho wire. The lanterns were allowed 10 ascend to height of sos feet before an attempt to lower the wire was made The wire ran out shcrt distance and then became jammed in the pulley Efforts to disengage | wire resulted in the green lantern coming detaohed. Ii fell and was bro. ken to atoms.
 The kite string and wire were reeled in, and white lantern was fastened to the piummet. This lantern was also de- etroyed i'll same manner as the first. Mir. Eddy aud his assistants again haul. ed ill the I'd aud wire and attached xed lantern to the p,ummet. Line al wire were extended until the twin lara- terms attained an altitude of 1, GOO faet, and then tho lowering plummet and signal lantern were allowed to descend safely to the earth. Dr. Mitchell nexn carried the lowered end of tho wire far down Lexington avenue and grounded it with steel rod. Mir. Eddy did like wise with bls end of the wire, the tele- phone transmitters vera attached, and tho aerial circuit was established.
 Satisfied that telephone communica- tion was practicable, both experiment ters signaled Mir Allen at his interms- diate station. It was half past g o'cIo0E when Dr. Mitchell sent the first vocal message to Mir Eddy.
 Hello, do you get me?' he queriod
 Yes, good, replied Mr. Eddy.
 General conversation oyer the wire ensued, Mrs. Eddy, Mir. Allen, FredeB- iclz M Wilson and a reporter partioi< pating. A times watches were held against the telephone transmitters, and their tickings were plainly heard at ths ether end of the wire. Once or twice the telegraph sounder was attached, and the clicking of the Morse alphabet on the instrument was carried clearly to the talanhone receiver at the other end of the circuit. The wind 8 fluctuations per- mitted tho wire to sag so much at times that it crossed the upper wires of the long distance telephone lines stretched along Lexington avenue, and scraps of conversation were transmitted to tbs experimenters. During the operations the lantern at the apex of the wire arch burned cut. leaving the point of con- neetion in absolute darkness.
 The wire used in the experiment. was a thin copper filament, about the size of patent thread, and entirely bare. Be- ing spspenG d from the kite string and freed from connection with any surface object except at the ends, it was DOT feetly insulated from every element save the ground and atmospherioal electrical currents This fact made the wire mo potential in conducting the messages transmitted.
 The success achieved by MT. Eddy in his experiment. demonstrates the fur. ther utility to which his aeroplanes can be put by the arny's signal service de- partment. Rivers and straits, forests, towns, areas of country where trans portation and telegraph facilities have heen discontinued can all be quickly bridged in daylight or in darkness Tor the establishment of temporary tele. graph or telephone system. The use of insulated wire and electric batteries and complete telegraph and telephone instruments in connection with the kites will dd 70 the practicability of the novel idea. The direction of the wind is no hindra. .sce to the use of such 2 system, as the ae oplanes can be flown from either of two objective points, It
