COMPLETED ENGINE AND GENERATOR up with the laminations, and correspond to similar air ductsplaced in the field poles. The draft produced by this com-bination of air ducts in the stationary armature and re-volving field is expected to give sufficient ventilation tothe generator to enable it to be considerably overloaded,but as yet no overload tests have been made. The care with which the original design was laidout is shown by the accuracy with which the parts ofboth engine and generator have been put together at thestation. The engines are placed so that there is just suf-ficient room between each for the removal of the longCorliss valves in the high-pressure cylinders, there beingbut about 1 in. clearance when the valve is being taken cylinder of engine No. 8, the first engine to be erected,which stands at the west end of the power house, is soclose to the offices in the gallery that a door has had to becut in the office front in order to allow of the removal ofthe low-pressu
