found forthis cast-off relic of the old mining days. Youhave been reading recently how the hydraulicmonitor was used to clear space for the Drumpower-house on Bear River; well, I want to tell you that its revival dated not fromthat construction work but from ours, severalmonths previous. When we cleaned out the reservoir wefound its bottom covered to a depth of fromthree to eighteen feet. Without the use of thehydraulic monitor it might have been a workof some magnitude to remove this large amountof useless material, in substance upward of80,000 cubic yards, but as I said before themonitor did the trick and in short order. I should mention that it took four of themto do it. We had Monitor No. I, and Moni-tor No. 2, and two spare monitors to taketheir places on occasion. To furnish the water and the necessarypressure for these monitors we had recourse totwo centrifugal pumps. These were installedat the lower end of the reservoir, one on eachside and located a few feet below high water
