The decrease in the measure of steam in the low pressurecylinders, due to the position of the superheater, is well illustrated in this test by comparing it with No. I, in which theamounts were very nearly equal.

The profile of this section is shown by Fig. 10; the maximumgrade is , and there are two spiral tunnels of 2,890 ft. and3,200 ft. long, having a radius of 573 ft. The regular locomotives working on this and similar gradesin the Rocky Mountains have general dimensions as follows: Type ~-;^—> Class (Ry. ) M—4 Cylinders 21 >n- ^ 28 in. Driving wheels,
