The firebox is 108 ins. long and 66 ins. wide,and provides a grate area of sq. ft. The ratio of heatingsurface to grate area is thus 82, whereas in their previousengines of this type with similar design of boiler, but withnarrow firebox, the ratio was as high as 119. As in the consolidation engines, a large number of flexiblestaybolts are used, there being 376 in the sides, and 115 inthe back-head, while all the throat stays are of the flexible.

The crown and side sheets of the firebox are in onein diameter, and have a maximum travel of 5 ins. They have piece, as are also the outside side sheets and admission and are designed with 1-in. steam lap and The dimensions and weights of the consolidation loco-no exhaust lap or clearance, and are set with J4 in. lead. motives follows: The frames, which are of wrought iron, consist of a main Cylinder—Type, simple piston; diameter 22 ins. frame with single front rail integral with it and a slab form Cylinder—Stroke 30 ins. of trailing frame spliced to the main frame just back of Track gauge 4 ft. x 9>y2 ins. the rear pedestal. The main frame is 5 ins. wide, while the Tractive power slab frame is 2y4 ins. wide. Wheel Base—Driving 17 ft. 9l/2 ins. One of the most interesting features of the design is the Wh
