. Bulletin - United States National Museum. Science. I have been away from Yakima, except for an occasional day, for a year, and arrived here two weeks ago. Last Saturday, March 26th, I exhibited your new type meter at a meeting of Engineers here, most of whom are engaged in Reclamation work. They were much interested, but criticised the meter severely .... I cannot comprehend how an engineer, who must have known the conditions under which a meter has to operate, could have designed such a device. The upper bearing in my first meters was not worn or cut by grit; the lower pintle bearing was not cut or worn; and the hardened steel pintle and its hardened steel bearing did not rust .... The water with the grit it contained was kept out by the air which was compressed in the inverted cups. The upper bearing of thii meter has no air trap to keep out water and grit, and the lower bearing is nearly as inefficient. The upper bearing housing is. I believe, four times larger than necessary. The large housing produces eddy currents, which may cause some inaccuracy in measurements. If I can go East next simimer, I would like to have you build a meter for me, at my expense, that I would not be ashamed to bear my name. I will express your meter to you today. That letter might have created considerable con- sternation, especially in the Geological Survey where the new design had been sponsored, had it not been that prior to May 18, 1926—several months before the letter arrived—someone had already conceived of the idea of moving the upper bearing from the stem of the contact chamber to a much higher position within the chamber. The air trap in that area was thereby provided for the first time on Small Price current meters. That change first appeared in Gurley's drawing no. 8250BS, dated May 18, 1926. The first production lot of the 622 meters was manu- factured on the basis of that drawing so that only the small experimental lot contained the fault Price criticized most severe
