A.— better way to maintain proper lengthsand distances of these parts, in the gover-nor, is not to trust to measurements, butto get a new governor and make a steeltemplate which shall give the distancesand lengths. Allowance must be made forseats that have been ground deej) into the r,j. triples to go into quick action. This ten-dency is also increased by neglected con-ditions of the triples. As it takes lesstime to draw a given amount of air pres-sure from the train pipe of five cars thanten, the tendency to get quick action isgreater on the shorter train. By addingon cars you decrease the tendency, andeven get beyond it. A broken graduatingspring would also cause this, but is lessfrequently the fault than the one givenabove. (4g) J. A. S., Creston.

Concord, N. asks:What causes the governor to blow backby the diaphragm valve seat when therelooks to be a good seat on both. Some-times the governer blows back from 10 to15 pounds before it stops, it seems towork all right otherwise. What will rem-edy the trouble? A.—I. We infer that theblowing back referred to is through thesmall port in the neck of the diaphragmbody 62. and that the pump fails to shutoff until the air pressure falls 10 or 15 (48) W. A.
