The slide-valves are underneath the cylinders, and thusgive self-acting drainage : no drain-cocks are required, nofrightening of horses. This arrangement saves one-sixth ofthe fuel used by engines with slide-valves above cylindt r». Vol. LXVIII, No 5.] AND RAILROAD JOURNAL. 229 2 The working gear, connecting and coupling-rods, areall in the same plane. 3. The bearings and springs are outside the wheels, andthe tanks inside, which gives steady running on narrow gaugeson uneven roads. 4. Slide-valves are of the Church pattern, which are self-adjusting for wear, . . never require readjusting. This isof importance in countries where no shops are at hand. 5. All lubricatiou is by means of grease absolutely closedagainst intrusion of grit, saving of 90 per cent, of material,and vastly reduced amount of wear. 6. All valves which have to
