Mikado type shows an increase in tractiveforce of 31 per cent.; in grate area of 32per cent, and in total equivalent heatingsurface of 95 per cent. The boilers of the Mikado type locomo-tives are of the modified Wootten type,equipped to burn a mixture consisting oftwo-thirds fine anthracite and one-third1)ituminous coal. The boiler has a straighttop, while the throat, back-head and roofof the firebox are sloping. Flexible stay-bolts are used exclusively in the water-legs, while the front end of the crown issupported on three rows of Baldwin ex-pansion stays. There are two power- ope-rated fire-doors, placed low down in theback-head. The grate is of a design whichhas proved specially satisfactory on thisroad. It is composed of rocking-bars, nodrop-plates or water tubes being bars rock in six sections, and aresupported on two intermediate longitu-dinal bearers and two side bearers. Care-ful atten
