The four water wheels of the plantwas made by James Leffcl it Co. of Springfield, rest on the Hoor and take their water supply from thepenstock through five-foot openings, each wheel having anindividual supply. The inlet pipes to the wheels can beclosed by valves operated by hydraulic pressure. The valvesare 60-in. and made after Mr. Johnsons plans by R.
