Editor: Almost every road that I have beenover, since starting on my travels, I findhas more or less difficulty in lubricatingthe 9K-inch pump satisfactorily, and Iam sometimes asked why it is that onepump of this class will run smoothly with-out groaning on a small quantity of valveoil fed regularly, while others groan al-most continually, although the supply ofoil allowed them is quite liberal. At first I attributed the trouble 10 theleakage of oil through the joints of thegovernor c6nnection where the nuts ofthe governor were not screwed up per-fectly tight, and to leakage through thedrain cocks whenever they were not agood fit, or through carelessness or forget-fulness they were not closed wh
