The Electric Trumpet

Mr. Ilarry B. Oox, of Cincinnati, has created considerable cxcítement in the ndghborhood of Fernback of late witli an iiitriiinciit. which is nothing moro tlmn a largo tin Mora with a crooked mouth piece. He lias worked for sevcral luouths to perfect tlie instrument, trying all sorts of uluctrical appliances to accomplish tbe resulta wished for, but tinally liscovered that tho siinple8t device wa8 th e best. Tlie inventio is tho outgrowtli of bis discovery of the great distance an echoed or reyerbrated sound would carry, and tbe discovery tbat speaking trumpets, it' made to give the same fundamental note would víbrate and produce tlie phenomenon known in acousties as "synipathy," With this trumpet conversation Ín an ordinary tone of voice was carried on between parties four and one quarter miles apart. From the laboratory the spectators, standing about two feet away from the bell part of the trumpet and quietly listening, distinctly heard a locoinotive whistle at Sedamsville, and at each 8urrounding station until it reacued Fernbank. Then the nunbUüg doÍM of the wheels of the train, as it passed over the track Uaving Ferabank, grew lesa and less, and when blowlng for road oreatkigl aiul stations the h hi.-tle was plainly hcard until the train arrived at Lawrenceburg, Ind., making a total range of twenty-six miles in wliich til ose present at the laboratory could follow the 8oundof the train. The ra il road timetable M used to (lesiónate tbe stoppagos and tlie train on arriving at Lawrenceburg, was one minute and forty seconds ahead of the time on the tcheaule. l'eople sitlnjr :it thcir Windows or on the porches of their liouses a mile away, conversinfi in an ordinary tone, conld be distinctly heard, and in ¦ eotiplf of instances, in order to verify the aecuracy of the tust, they were told the nature of thcir conversation, and admtlted that Hlcb h.ul t:iken place. Yot It w:is a difli cnlt matter to ttiefia believe tbat geveral pemou were aüiflud by their re inarks by nieans of a tin bom mile away. About dusk another evenln;, Mr. Cox nul his brothcr, who is an Episcopal clergyuun having charge of the city missione, made scveral aiuusing tests with the horn. Tliey experiinented upon an old darkey, and completely frustrated the old fellow, who was walking up the roail. Using the bell end of the hom, they began talking to the colored man as he walked aloog. The peculiarily of sound tiansmittcd by the trumpet is, that to the pcrson hearing it, t appears to come from sume one near him, and not from a distance. 'l'be old darkey hearing the voice was at tiist annoyed, then puzzled, and finally so badly frightcned that he started up tbe road on a dead run, no doubt attributing his adventure to soine siipernatural agciicy. Another more satisfactorj' te-t was made, Mr. Oox, taking a skift' at the river, rowed down gtream a couple of niilos, and landing ascended to the Kcntucky hills. In the meantime another genuenian left Fernbank and going a little to the nortbeast, went out betweeu two and three miles to tbe hill-tops back of that place. K-ich one carried a trumpet Mr Cox asked flrst if the other gentlem m was rcady, and an immediate respoiiM was had and a conversation was kept up for 30111e time, each one talklng in his ordinary and natural tone of volee. Tests were made on the rivcr, and they proved to be more dMtltflt on (he water llian upon land.
