nected with it, one of them thirty-five 

 horse-power and the other forty-five 

 horse-power, and the larger one seems to 

 get the greater part of the draught. The 

 boilers are of the return tubular type. 



W. H. M. 



It is not customary to partition a 

 smokestack into flues, but in the con- 

 struction of house chimneys this is a 

 common practice. From what you say 

 of the size of your' boiler and the size 

 of the stack, I fear the stack is too small 

 for both boilers. The forty-five horse- 

 power boiler should have at least a 24- 

 inch stack, and the thirty-five horse-power 

 boiler should have about a 22-inch stack. 

 It may be desirable to put an iron stack 

 on one of these boilers, in addition to 

 the brick chimney. L. C. C. 



THREE CONNECTED HOUSES. 



We are erecting a range of three 

 greenhouses, each 33x110, connected and 

 running north and south. We are using 

 18-foot rafter bars. There are glass 

 gables and two feet of glass in the sides. 

 We intend to use the houses for growing 

 carnations and a general line of bedding 

 plants, and we wish to heat to 56 de- 

 grees in zero weather, using steam. How 

 many runs of l^-inch pipe will be re- 

 quired? We will have five rows of 

 benches and would like runs under each 

 bench. The boiler room will be at the 

 southwest corner of the greenhouses, 

 with a potting shed 16x99 feet. We 

 should like all pipes connected with a 

 cut-off, so that any pipe can be used as 

 desired. 



Can these pipes be fed by a 4-inch 

 pipe running across the north end and 

 returning to the boiler? If so, do the 

 l^^-inch pipes returning to the 4-inch 

 pipe require to be reduced to a %-inch 

 pipe to keep it from pounding? Where 

 should the air valves be placed? 



A. J. B. 



There is nothing to indicate the loca- 

 tion of this plant except "zero." Mj 

 plan for piping this plant would be to 

 carry a 4-inch pipe from the boiler to 

 the center of the first house, carrying 

 the pipe nearly as high as the comb of 

 the house; here take off a 2-inch flow to 

 run under the ridge of the house to the 

 far end and return ^y fifteen 1 14-inch 

 pipes under the benches. From the cen- 

 ter of the west house continue the main 

 flow. pipe in the potting shed by the use 

 of 3-inch pipe to the comb of the middle 

 house, and take off a 2 -inch flow for it, 

 to be carried to the far end and return 

 by twelve l^^-inch pipes. From the 

 comb of the middle house carry a 2-inch 

 line to the comb of the last house and 

 continue it to the far end of the house, 

 to feed fifteen 114-inch returns. The 

 range will thus be provided with an in- 

 dependent flow for each section and fif- 

 teen, twelve and fifteen returns, respect- 

 ively, or forty-two 1%-inch returns in 

 all. These returns can all be emptied 

 into a 2-inch main return, and as many 

 as desired may be valved to provide a 

 range of temperature for the control of 

 the plant. L. C. C. 



Pana, III.— R. O. Henderson, proprie- 

 tor of the Pana Greenhouses, will tear 

 down the old houses and rebuild next 

 season. He has purchased glass and pipe 

 to erect an addition of 7,500 feet of 

 glass. He will use iron gutters and build 

 cement benches.

gkntlkmkn:— You can strongly and unhesitatingly recommend the 

 "Eclipse" piston type reducing valve to florists. We have two, purchased 

 of you last year. We would not have them out for double their cost, and 

 find them as sensitive as a watch. We will be in Chicago soon to take up 

 the vacuum system with you. Yours truly,
