Several of the olcier railroads have begunto use electric instead of steam locomotives. The most wonderful use for electricity was yet to men had long known that electricity travels throughspace without the necessity of following a wire, like waveson the surface of the water. In 1896 Marconi, an ItaHanelectrician, invented an instrument for telegraphing throughspace without wires. The method was rapidly improveduntil messages could be sent across the Atlantic Ocean andfrom ship to ship in mid-ocean. The wireless telegraph, 466 THE NEW METHODS OF WORKING. invented in Europe, was almost immediately adopted in theUnited States. Within a few years after the invention of the dynamo, themotor, and the electric light, many private companies went into the business of makingelectric current and selling itfor lighting and for runningmachinery. Some electricplants use coal for fuel, butothers depend on waterpower. In 1902 great ma-chines were built to use apart of the water of NiagaraRiver above the Falls. Theelectric current is carried onwires to Buffalo, 22 milesaway, and even to citiesmuch farther off. In theseit is used to light streets andbuildings, run factories, andmove street cars. Rivers aremade to do work which wouldrequire thousands of nineteenth century wasthe age of steam, but thetwentieth century is becoming the age of electricity.
