Messrs. Schneider and Co. have built 2,684 locomotives since they commenced this brandi of engineering in 1838. Figs. 289 to 313, Plates LXI. to LXVIL, are diagrams of some of the principal types, and to eacli figure the leading dimensions are appended ; they form inter- in Fig. 283, and Figs. 284, 285, Plate LIX. ; Figs. 286, 287, Plate LX. ; and Fig. 288, page 109, are general and detailed views of an express passenger locomotive constructed at Creusot for the State Railways of France. The illustrations are so complété that only a short description will suffice. The engine lias four coupled wheels and a four-wheeled front truck ; the cylinders are placed outside the deep plate frames which are extended well forward of the truck, and bevelled at the end to receive the sharp bow-plate covering of the smokebox door, a device introcluced to reduce tlio air résistance when running at high speeds. With the same object, the front of the drivers cab is finished with a pointed curve, as will be seen by reference to the general elevation, Fig. 283. The construction of the truck is Fig. 283. Express Passenger Locomotive for State Railways of Fiance. ësting illustrations of Schneider and Co. in the progress eftected by Messrs. this brandi of their Construction Department. The following list indicates the manner in which these locomotives have been distributed : Locomotives. Tenders.

The boiler and outside firebox shell are of extra mild steel plates, and the tubes are of steel on the Serve system. The firebox and the front tube-plate are of copper. The firebox is of the Belpaire type, and is placed between the driving wheels, so that a considérable depth is available ; it is fitted with a brick arch, and the details of the drop-bars in front are shown in Figs. 284 and 287. The niethod of staying the firebox is illustrated by Figs. 284 and 287 ; the firebox stays are of copper. The boiler is fitted with three safety valves, two of which are on the dôme, and the third over the firebox. The boiler is fed by two 9.5 millimétrés Friedmann injectors placed at the back of the firebox, as will be seen from b ig. 286. lhe
