Outside of the building, at places where the oldwalls had fallen, pilasters were built to sustain the endsof the trusses, which were built right into the walls, stonesbeing placed in the wall to receive them. Inside, a tim-ber was set under the truss, and framed into it, also boltedto the brick-work, with large star washers outside. Wherethe old walls were standing, and the steel posts remained. FIG. 3.—LATHE FOR BORING BEARINGS built into the walls, the end of the truss was placed ontop of the steel built-up post, and the wooden post car-ried down nearly to the ground and bolted through, asdescribed, another section of wood being used on theother side of the wall, instead of the star washers.

The shop is lighted by monitors built in the roofs,the section of roof (.there are two sections) furthestfrom the vertical windows in the walls being furnishedwith a higher monitor than the section of roof nearestto the side-wall windows.
