CONCRETE FOR CHIMNEY.

To put up scaft'(dding and a 1 rame to 

 build the chimney of concrete, as you 

 would, a wall would be very expensive 

 and then, again, if built of concrete 

 blocks, whieh are now extensively manu- 

 factured, it would not l)e :is serviceable 

 •is brick, for concrete does not stand fire 

 as well as brick. 



You do not say whether it is for a 

 ■«team boiler or for several water heaters 

 \'>n want to use the ehimne}. If for 

 -t'am, I can toll you soinetiiing definite. 

 ^ .uir 20,UOO feet' will nee(l two thirty- 

 'i\e horse-jiower boilers, or one of sixty 

 :i seventy horse-power to do the work 

 ■umfortably. Such an outfit will need a 

 ■liimney fifty feet liigh and tuo feet in 

 1:1 motor; that Ls, a two-foot ojiening. 



We often see immense stacks built in 

 t n-tories wliere a large amount of power 

 '- used and occasionally see greenhouse 

 -ream plants with tall, massive smoke- 

 -taijk?. I)epend on it. the higher the 

 -tacks the more cconemieal tin fuel bill. 

 If you are using a return iliio tubular 

 boiler, the fire will burn and niake steam 

 with a smaller and shorter smokestack 

 'han ia often seen, and that may appear 

 to some as .all you want. Not so. With

BOILER AND PIPING. 



What gives the bi'st heat i'nv gniwing 

 ,-arnations, lettiiee and a general lino of 

 other jilant.s, siu-h ji- ;;eraniums, lielio 

 tropes, etc..' 1 lia\i' .a greeiihouse 2(l\ 

 (i4. 'J'he walls are briek ami live mul 

 onedialf feet high, with two feed of glass 

 the full lerit'lh on the soiitii side. It is 

 ten feet to the ridge. .\t the center ot 

 the north wall of this greenhouse is a 

 brick house KixL'i' feet, with a basement 

 of the same size, '["he basement tloor is 

 five feet below the floor of the green- 

 house. Would it be deep enough to ae- 

 eommodate a boiler.' West of the bri<d\ 

 house and adjoining it and the green 

 house I ha\<' now. I want to build ;iii- 



I'lii a ]il,nit no larger than the house 

 -0\(il ,nid the contemplated liouse -2x215 

 !■ et a liot-water system will prove most 

 --111 isfactory, and even if there were an- 

 other house 20x(j-t parallel with the pres- 

 ent one of that size, 1 think water would 

 -^lill lie most desirable, 'i'hc cost of in- 

 stalling the piping for water will exceed 

 that of steam by a few dollars, but the 

 cdst of maintenance will be le.ss, as the 

 water will require less attention. 



The basement of the brick house is 

 deep eiiougii to accommodate any one of 

 till' modern hot-water heaters of proper 

 capacity to sup{>ly heat for these green- 

 linuses. Do not get a second-hand boiler 

 unless you know it to be a goorl one. 

 A three-(|uarter span house with the long 

 side to tiie soutii wduld be satisfactory

 m.-ikes for success in gre(>nhouse work. 

 I 1 .annot ('stimate the cost of the pipe 

 ,ir I lie work for you, but can say that to 

 pipe the house 20xt!4 it will require 

 .-ibout S(l(t lineal fe(>t of Jineli pipe for 

 lid degrees temperature; in the house 

 ■_'"_'x23 feet ;i20 lineal feet of 2-inch pipe 

 will be required. To heat two houses 

 2(iN<;4 and one 22x2:'. feet, about 2,00U 

 feet nt' 2-in<h pipe will be reijuired. A 

 lint-water bidlei- large enough to do this
