This apparatus may,of course, be replaced by the American type of receptor using insteadan auto-coherer and a pair of head telephones. One of the strongestfeatures of the new system is its applicability to firing mines byelectricity, w-hen the key of the transmitter may be made to closeand remain so for a predetermined period of time. A correspondentfrom Berlin has communicated to the writer the interesting newsthat the German Government is now testing the merits of the systemfor specialized classes of work. To facilitate the directing of the lenses, small finding telescopes—called finders—are rigidly mounted on the levers in front of grad-uated and arcuated bars, v, and the flexibility of the system makesit especially commendable for serving a greater variety of purposesand in a more exact manner than is possible with the ordinary wire-less telegraph.
