They will be the most modernthree-phase machines and built to be easily moved forrepairs. The increase of temperature after a continuous run oftwenty-four hours at rated speed must not exceedforty degrees centigrade above the temperature of theair at five feet distance from the shaft. The inherentregiilation of the dynamo shaft shall be set with thedrop of potential between 10% at rated load, and thenon-inductive load shall not exceed 6%. The dynamos are to operate regularly and parallel, having commonbus bars. And in so operating, each dynamo mustcarry its portion of the total load. The insulation isto withstand successfully a potential ten times as greatas that for which it is designed, and the armature to betested for twenty thousand volts. As already stated, the wheels shall be connected sixto each machine, there being twelve machines, there. Mr. Peter Lvall, Director. will be in all seventy-two wheels. The power housewill consist of a building about one thousand feet longwith three centre portions divided off so as to form thedynamo house starting from the shore. There will be on each line of shaft six wheels and agenerator ; then a generator and six wheels ; thenagain six wheels and a generator and a generator andsix wheels ; then six wheels and a generator ; then agenerator and six wheels. This doubled will completethe electrical lay-out. The building is of steel con-struction, the dynamo portions being Laprairie pressedbrick. The foundations and flooring of the dynamohouses are of concrete and steel beams, and the turbinesheds of steel work with three inch plank covered withcorrugated iron.
