In America none but recording instruments have ever been used. Of these we have many kinds, but only five are in operation at present, namely:--The electro-magnetic timing instrument of Professor Morse; the electro-magnetic step-by-step printing of Mr. House; the electro-magnetic synchronous printing of Mr. Hughes; the electro-chemical rhythmic of Mr. Bain; and the combination-printing, combining the essential parts of the Hughes instrument with portions of the House. The Morse apparatus is, however, most generally used in this country and every other. Out of the two hundred and fifty thousand miles of electric telegraph now in operation or in the course of construction in the world, at least two hundred thousand give the preference to it.
