It is stated that Prof. Morse founded his alphabet upon information given him by his brother, a journalist, as to the numerical relation of the letters in the English alphabet, the simplest signal (a dot) being given to E, nnd the next simplest Ca dash) to T, those letters occuring the most frequently in our language. t For the generat ion of power in the electric telegraph, Daniell's batteries (, see Galvanism) are chiefly employed in this country.

In pole and over-house lines, the wires are kept from each other and from contact with the earth by insulators of various kinds. White porcelain and brown stoneware are the chief materials used. The former, when of good quality.well glazed and well burned.is perhaps the most perfect of all insulating materials, and does not deteriorate with age. The fewer the poles are in number on which the wires are suspended.the better is the insulation and the less the cost, hftt the liability to accident is probably greater. The number of poles used varies from 16 to 0 per mile, and is governed by the number of wires carried, the configuration of the track, and other considerations. On road lines, the number ...
