We have heretofore alluded bneiíy to j a plan devised by Mr. B. Holly, of Lockpotr, to heat tluit city by stenm. Tlie Tjockport f i "ui supplies a more extended oocotint of the propoeed experiment, and it is bo curious that it will be rend with genera] interest. It (teem that a ntunberof substnntial eitizens of Lookport have fonned a ooiupnny wuler the I iiiinic of the "Holly Steam Gombinat.ion Compatiy, Limited," nnd have electeil n Board of Directer, iit which 8niuut.' Rogers, I). F. Bishofi, I. H. Bnlwuck, F. N. Trever, B. D. Hall, and M. M. Hontlrworth are apsoeiated with Mr. Holly, and the experiment íb actunlly to be ' made onder the folloAVing estímate ; Kstimated proent cost for coal, wood, ling, labor, repair of tovos nnd fiirnaces for warming tiie foUowing district, in the city of Lockport, being about one-hall mile sqnare, buunded a follows : Eaat by Wa)ington street, south by Higli rtreet, wciit by Salon treet, north by Caledonia I street, includ'iug the followiug : !

If the city is onc niile square, four nets of boilers will be uecemsufy. The inain pdpes that lcave tlic boilers will lm four-inch, and will diminish to S, 2., 2, 1'i and 1 inch at the extreme end away from the boilers, the inains Of four-inehes 'eontinuiug as the nse along the linos may deniand. The main pipen are placed about fóur feet below the surfaco of the earth. The iron pipes are rirst eovered with asbestos, and tlion placed in WOOd L5ps two inchos thiek. leaving a Bpace for eontined air ■ between the asbestos and woud. The outside pipe keep all water and moisture from the i j steara-pipe and prevent condensation. The i pipes, ijoth wood and iron. are put down in lengtliK of two feet. when they tenninate in I low, upright posts, flrmly s(;ciircd in the earth. j The upper part of this post is arrangedso auto rec-clve the ends of the stenm-pipen through stuffing-boxes to allow the plios to expand and contract without moving the post. the posts are also arranged ko as to rcceive the ends of the sorvice-pipos oitlier with or without expansión joints. The Bervice-pipes are not taken directly from the mains. lint from the hollow supports, thiis aUowing them to be attached or uetácíied from the support instead of passing through the outside wonden pipe to entor f the Btewfl-pipe, trhicb could not be done ; cause the steam-pipe expanda and eontraets, : while the wooden-pipe does not. This ercomes onc of the most important objections to ' the use of long lines of underground , I i n - i. when'brAnob pipet iufe to be taken off. ' Another objeclion bas bvc.a condensation. This i the asbestos reduces about three-fourthn, and the air-space and WOOdon-pipe will reduce it I still fmtlier. Tests made during the month of lulv, itli vcr.v small pip?, prove that steam may be enrried through well-protected ]ii]ies for a niile. and then be more económica] than ;ui otluf Kvsteni. liut it is thought that 1,200 or ' 1.500 fèet oach way, niaking a halí-müe Bqnkre, j iti about all that 'ne'd be furnishod from one ! location. This, even iu a city with a population of 1,600, wonld include neaiiy all the busineMB i places, hotels, ohnrohes, and schools, linildUlge lurther out could be reached by a single line of small pi)'. Htcam can be numii'actured on a largo scale for one-fourth the cost th.it it ean on a small scale, for warming a single dwelling or bldok. Yon ean stop the expense at any time by turning the stcam-cock in your lum.-i-. wherciis in ur ui : piivat boiler, when ycai ' shut off the stiani. combustión goee on just the Bame. There is about 150 oubic feet of hot air per minute lost throngh the chimney.
