| contd :- -2- A trouble which we experience occasionally is for a minute piece of foreign matter to lodge on the valve seat and be forced into the alum. when the valve tries to close. This can put the damper out of action in one direction until it is removed. G.W.H. states in his last report that he ran into this trouble and had to dismantle an axle control damper, though he did not actually find the material that caused the damper to go out of action. It occurs to us that if the dampers had a consider- able pressure velocity increase after the valve this trouble would not be quite so serious as the damper, even with the valve open, would retain a considerable proportion of its effectiveness.
