CANADIAN MACHINERY At the plant under consideration,however, the annealing furnaces are ofthe most modern description, and havebeen carefully designed to give an evendistribution of heat. There is a specialfurnace for annealing locomotive framesand similar large castings. This is 40ft. long by 5 ft. deep by 6 ft. wide, andis fired by four fire holes along one from the tires passes over thecastings and enters downtakes in thefloor, passing thence through (lues un- 23. ANNEALING ROOM, SHOWING FURNACES IN COURSE OF ERECTION. The core ovens are located in themiddle of the core room, and are servedby trucks from either side in such amanner as to make their operation con-tinuous. They are fired by coke and areconveniently situated to serve both themain floor and the bench molders. The foundry is piped for compressedair and will eventually be fully equippedwith jar ramming and other molding ma-chines, as the work may require. The Annealing and Finishing Depart-ment. These are in a separate building meas-uring 60 ft. by 200 ft. It runs parallelto the foundry with which it connectedby a narrow gauge transfer track and astandard gauge shipping track. Thebuilding lias a height to the rout trusschords of 28 It., and is served through-out its length by a 10-ton Northernerane. There are three annealing furn-aces, all castings made by the companybeing carefully annealed. While moststeel foundries are now giving this mat-te
