WIRELESS BUGLE CALLS.

Tunes by wireless —that is the latest development of the marvels of electricity. Baron von Lepel has invented, and has successfully demonstrated in England, a new system of sending musical notes by. wireless which seems defined to play great part in the future of telegraphy. Two remarkable features of Lepel’s system of wireless are that very much less power is wanted to send a message over a long distance than with most other systems, and that the intense electric spark, so important, hut so noisy, a feature of many other systems, is entirely absent. But the genius of the Baron is most in evidence in the receiving apparatus he has invented, by which very feeble and indistinct signals are almost miraculously transformed into louder ones. Baron von Lepel uses a clear musical note instead of the toneless buzz of the ordinary receiver, and this note can be changed at an instant’s notice by merely depressing a key of what looks to the uninitiated something like a dolls pianoforte. The operator receiving a wireless message hears a succession of musical notes, and by means of simple adjustment he ean tune up his receiver so that they can be heard clear ami sharp, while ordinary wireless signals, which in the ordinary way would greatly confuse the opeiatoi, can be ent out in’a few moments so successfully that they cannot be heard at all. In a demonstration given this week, by pressing the correct notes of the timin'* keyboard already referred to, toe time ‘'God Save the King” was transmitted from Slough to Brussels with the utmost ease. -Bien entendu: vive J’entente eordiale!” came the reply a minute later. The tune was heard and recognised with the utmost ease. Xow, it is only a simple step from transmitting tunes by wireless to sending bugle calls, which may mean anything, prearranged bv code. Suppose the tuning keyboard had'lG or 2<l notes, think what an' extraordinary number of bugle calls, -tunes.” or musical messages could be sent from one ship to another. The musical code would lie a distinct novelty in wireless telegraphy, yet no one can deny it is merely a subtle bugler. The ‘•tunes” could lie heard, also, no matter how much confusion was attempted by the operator of ordinary wireless systems-
