The power house, together with the; niarliinc shopand boiler house, is of reinforced concrete, with iron roof. Anoticeable feature is the minute attention that has been givento details tending to insure continuity of operation. In the eventof fire in the mill or yard, the entire building can be completelyenclosed, and air supplied to the operating staff by means of twoelectrically driven fans, whose intakes are located at the sealevel, thus making sure that the fire punqis can be kept in 600 kw.

All tliese panels are enclosedin neat asbestos lined cabinets, with hinged doors on both sidesto admit of ready access to the switch gear, etc. Owing to the general excellence of the apparatus used it wasfelt that the work of installation and the materials employedshould be of equally high standard. Consequently it was decidedthat the regulations of the National Board of Fire Underwritersshould be observed to the letter. This decision rendered neces-sary the use of 3,500-volt lead covered cable, which was drawn
