(To be read Thursday, IHt,. Fcbrniiry, 1896.) Peun Y an has a population of about 5 000. It is situated at the outlet of Lake Kenka in the western part of New York State, about 50 miles southeast I'roiu Uoohestor. Lake Kenka is Ion;: and narrow, bcin'; about 20 miles long by i a mile wide, and it is very deep. It is from this lako that Penn Yun takes its water for fire and domestic purposes. At a distance of one mile up the lake from Penn Yan, the banks rise quite rapidly, so that it was easy to get a suitable place f u- a roscrvnir at a short distance from the lake, and at an elevation thatwuild give gooil pressure for 6re purposes. At a distance of about U milns up the lake from the town, t was decided to build a pump house on the shore, and extend an intake pipe out into the lake 550 feet, also to build a r.'sorvoir back 1800 feet from the shore and at an I'levatioii of ;$2ll feet above the surface of the lake. Survcyo, plans, specitieations and estimates were luade by the En- gineer, estimating the entire co.st for pumps, pump-house, reservoir, trenching, pipes, hydrant.s, etc . the whole system complete, to cost 500,000, whieh it did bolbre eoiupUtvd. The reservoir was located at such an elevation that ample pressure (90 lbs.) could bo obtained in tlie higher part" of tln> town, i'or the town was built on an ineline, as is shown by the eontour lines in the plan. The capacity of the reservoir was 1,000,000 gallons, which it was computed (in ease ol' accident to the pumps) could be delivered to the centre of the town tluoiigh tlio 12 ioeh pipe in 5 hours , this computa- tion was made from the formulae y = a(; = •785-1 .i^\/-^-?^-j 1-5 + A* A () inch overflow pipe was put in the reservoir 2 feet f-om the top of wall, and conveyed the water 75 feet ironi the reservoir. This pipe was computed to oarry off 850,000 gals, daily before the water would over- flow the walls. The following are some of the specifications ;— The trenches were 5 feet deep, and, where possible^ made in a straight line, wore kept dry and made wide enough that the laying and eanlking could be properly done, care being taken not to injure gas, wat(!r, or sewer pipes already laid.' The boxes for stop gates were placed vertically over and around the top of the gate, and then surrounded for a thickness of about 1 foot with small loose stones or coarse gravel, whieh was carried up to within 20 inches of the grade of the street. Upon this mass of loo.se stone or gravel a ButHcieiit amount of tine gravel was then deposited to form a bed f"r till' irate b,'x stone into which the jacket inclosing the upper portion of the box is suspended. Kvery jtipo, special casting, stop gate and liydfunt was liruily sup- ported ami ttdju.radc by a wooden block and two wooilen weilj^os, wliieh weio in f^cnt'ial placed near the hubs of the pipe .iiid iixture'* The lihicks were of sound lioiuloolc or oak, not less than !(> inches long 3 inches tliiek, and 9 inches wide, the wedges were 10 inches long, 4 inches wide, and ;> inches thick, these blocks were evenly sawed, and romiiined under the jiipe after refilling the trench. The spigots were inserted into ihi' hubs, so that tlu' shouldi:v nf the hub was in close contact with the fucc of the spigot, and were then ad- justed by the wedges so as to give an even and unirorni space all around for the lead joints. Hemp yarn was .lecurely I'l'iveii into the joints, so as to leave 2^ in- ches in depth and at least ,'„ of an uieh in thickness all arouu il il of Water System . - *•• . ...^i'C . :-^ .
