The electric drive has been of material assistance in the lightingof the shops, which is further increased by large window the buildings have been made as fire-resisting as possible,special attention has been paid to this in the case of the patternstorage building. This is four stories in height, whereas the patternshop, which is built as a lean-to to it, is but one story in floors are used throughout and fire walls divide the build-ing into sections. The windows consist of wire glass in iron frames,and the roof is covered with the H. W. Johns-Manville Companysasbestos roofing. The various buildings are separated from one. to unite all sources of power in one location. In this instance,however, the works as laid out will eventually have two independentpower plants. Such a course has been deemed advisable as certaintyof operation has been considered of greater importance than anyeconomy which might result from the con-centration of the two plants in one. It, ofcourse, will be readily appreciated thatpower in such an establishment, althoughnot an insignificant item in the cost of pro-duction, nevertheless is not the most im-portant one. Although with modern motor-driven tools, the possibility of a shut-downis not as great as formerly with line shaft-driven machinery; nevertheless, the possi-bility of an accident to the power plant itselfis a factor not to be disregarded. Except in a few cases where it was notadvantageous to do so, the electric drive hasbeen used As a large part ofthe machinery consists of variable-speedtools, and also because of the extensive useof cranes, direct current has
