A GREAT ENGINE AND BOILER BUILDING PLANT. By an expenditure equal to about one-third the original investment represented in the plant of the Detroit Dry Dock Company, Detroit, Mich., the capacity of the different works was doubled in 1892, and the plant as a whole is now among the finest in the entire country. Improvements made by this company were mainly in the Dry Dock Kngine Works, connected with the dry docks and wooden ship building plant at the foot of Orleans street, Detroit. The new engine works have a frontage on three streets and are so constructed that great advantages in light and air are secured from an immense skylight and large windows extending the full height of the building. The construction is of steel and brick with fire-proof floors and roof. The entire building is 200 feet long, 66 feet wide and 50 feet in height. The main shop for the erection of engines and for heavy machinery runs the full length and height of the building and is 37 feet 3 inches in width. From this main floor space there is an addition 26 feet 6 inches in width, which also runs the full length of the building, and which is divided into three floors, the first, or ground floor, being used for power purposes and for heavy machinery, the second for light machinery and for bench work and the third for the storage of patterns. An elevator affords ready access to all of these floors, or galleries, and there is an abundance of light and air from the fact that there are no partitions between them and the main shop space, while the facilities for the transmission of power and the handling of material by a large electric crane in the main shop are most complete. One end of the main structure is reserved for the erection of machinery, and the space devoted to this purpose admits of four of the largest triple expansion engines being put up at one time. At the other end of this main portion of the building the large tools are so arranged that work from them can be readily transferred with the least possible difficulty by means of a 20-ton Shaw electric crane, which runs the whole length of the building, and which can be applied to heavy work in the galleries as well as in the main shop. This crane has 37 feet span and the space
