POWER STATIONS AND DISTRIBUTION OF POWER 415 ciprocating engines and so to get an efficiency superior to thatof either type alone. To gain greater stability, steam-turbine units, whether ofthe Parsons type built by the Westinghouse Machine by the Allis-Chalmers Co. or of the Curtis type built bythe General Electric Co., are now manufactured with the axishorizontal. This means more floor space, but on the otherhand it is more economical of head room. The gas engine has come in recent years to be a real rivalof the steam engine as a prime mover. This is especiallythe case in places where there is an abundant supply of naturalgas. In localities which do not have cheap natural gas butdo have cheap coal, producer gas is commonly made. Oneadvantage of the internal combustion engine is that it can bemade to
