Sketch of Broken Turbine Shaft not spared. A peculiar and perhaps significant relic of the machineis the turbine shaft. This shaft was approximately 13 in was broken in two places and the bolts of the flange coupling betweenthe turbine and generator had partly sheared and broken ofif. Onepiece of this shaft, about 4 ft. in length, marked A in Fig. 3, afteran extensive air flight, lodged in the basement under the piece, 8 ft. long, with the flange coupling, was hurled througha window into the yard. This latter piece, shown at B in Fig. 2,has a considerable ofifset, doubtless received an instant before theshorter piece of shaft was broken off. From the appearance of thebore of the turbine discs, all of which were considerably enlarged andbelled out and from the fact that the piece of shaft on which they hadbeen mounted was found after the wreck at some distance from thediscs, there
