Mr. Chesney points out one thing that should be considered in two ways, the extra floor space required. It is true that if one considers the space taken by the condenser outfit for cooling the oil and the extra pumping apparatus necessary, more floor space may be required, but that extra floor space can usually be found in most stations. The space necessary for the cooling apparatus, the pump and condenser, is not so great as the space occupied by the transformer, and they can usually be put away in some corner in the station. Also in several cases I have found it advisable to install this cooling coil, not in a part of the station but, say, in the tail-race, using the water from the turbine to do the cooling. There is not, therefore, the complication of extra pumping facilities; there would be one set of pumps similar to those that are ordinarily used for forced water circulation in a water-cooled transformer.
