When there is 'no current, the spring s brings e 1 back against the insulated screw S'. The pillars JV and P are connected with the poles of the local bat- tery. The metal spring s places the lever e e 1 in connec- tion with P. The screw 6 1 and the end e' of the lever, then, are virtually the poles of this battery. When these are in contact, the local current flows, and it stops when e' is brought back against the screw S'. The receiving instrument is included in the local circuit. When a cur-... rent comes from the sending station, the keeper A is attracted, e' falls on S, the local circuit is closed, and the receiving instrument begins to print. When the current ceases, e' returns to S', and the style of the receiving in- strument is withdrawn from the paper. By this means, a current too 'weak to 'work the receiving 1 instrument can complete the local circuit and print legibly. 325. The Telegraphic Fire-Alarm. The electric telegraph is now extensively used for indicating the locality of fires in cities.
