Pacific Coast Convention to be Held in Salt Lake City, Sept. 6-10
This year the Pacific Coast Convention will be held in Salt Lake City, Utah, beginning September 6 and continuing through for four days. A number of very fine papers have been arranged for and the well-known hospitality of Salt Lake City and the points of interest in and nearby this city insure an enjoyable meeting.
The technical papers will deal with such subjects as high-voltage transmission, corona, surge recorders, stability of alternators, distribution stations, the growth of population, power-factor correction, protection of oil tanks against lightning, transcontinental telephony, carrier communication on submarine cables, electricity in lead-silver mines, safety in mine application and engineering education.
The general committee in charge of arrangements for the meeting is as follows: C. R. Higson, Chairman; P. P. Ashworth, H. G. Baker, V. L. Board, D. L. Brundige, R, J. Corfield, G. S.
