Although the propelling machinery for a large passenger vessel like. the President Coolidge is consider ed the most important part of the entire mechanical equipment, con sideration must be given to the, large number of auxiliaries upon which the propulsion machinery is dependent for continued operation, and the very appreciable amount of auxiliaries necessary to the comfort and service of the passengers' and' crew. How completele the electri fication has been utilised on this ship for mich services may be judged by the reference to the nume ber of motors, fans, and stateroom heaters which have been installed:
