In order to reduce trouble with frame breakage as much aspossible, the matter of substantial bracing has been given par-ticular attention. The frames are in two parts, the main sectionbeing 5 in. in width and 7j4 in. in depth over the pedestal. Thetrailer frame is spliced to it and is 4 in. in width. In additionto the cylinders and the firebox supports, these frames are bracedby a heavy casting at the guide yoke and but slightly less heavybraces between the other pairs of drivers. An inspection of theillustrations of two of these braces will give a good idea of thecare this feature has been given. The cylinders are cast separate from the saddle, and the frontframe extension, which measures 5 in. x 13 in. at this point, iscompletely housed between the castings for a length of about 52in. Fifty-nine lYg. in. bolts are used to form the connection be-tween the cylinders and saddle, and ten of these pass through. Arrangement of Brake Rigging Which Includes a Connection to the Traiiing Trucl<. locomotive and measures 9 ft. in width by 12 ft. in length. Thegrates are of the rocking type with short fingers and narrowopenings in the center, suitable for the fine grade fuel to beburned. They are installed in three sets across the firebox and tlic frame. Exceptionally large exhaust ports are providedthrough the cylinder castings, and large outside steam pipes con-necting at the top center of the valve chest are used. It is statedthat these large steam passages have made a very free moving
