Gkntlemen:— 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,

Greenhouse Heating. 



PIPING IN MICHIGAN. 



Please inform nie as to the proper 

 method of piping a greenhouse 20x60 

 feet, with hot water. The house is ex- 

 posed on three sides. The height from 

 floor to ridge is ten feet four inches. 

 The walls consist of sixteen inches of 

 glass and two feet of concrete. My 

 j^sa is to use fifteen lines of 2-inch pipe. 

 Three feeders, connecting with a 3-inch 

 pipe from the boiler, would run to the 

 farther end of the building and there 

 <^rop into twelve returns, which would 

 gradually slope back and connect with 

 a 3-inch pipe leading into the boiler. 

 Ihe bottom of the boiler is four feet 

 below the greenhouse floor. If the fore- 

 going plan. is correct, should manifolds 

 be used or return bends? Should the 

 returns run directly under the benches 

 or at the sides? Should the benches be 

 placed first or should pipes be laid and 

 benches built over them? F. D. 



The house in question should be main- 

 tained at 65 to 70 degrees by using a 

 single 3-inch flow from the boiler direct- 

 ly ^} ^. *^^ ®°^ of the house, where it 

 Should divide to feed ten 2-inch returns. 



connected by manifolds and not return 

 bends. At the end near the boiler the 

 returns should be collected by manifolds 

 and lead into a 3-inch return back to the 

 boiler. It will be more convenient and 

 economical to do the piping before the 

 benches are constructed. L. C. C. 



STEAM WITHOUT NIGHT MAN. 



Will you kindly tell me if it would be 

 advisable to run a low pressure steam 

 system without a night man, with nat- 

 ural gas as fuel? It seems to me that 

 by putting a regulator on the gas at 

 the boiler, a good safety valve on the 

 boiler, and thermostats in the houses, I 

 could go to bed and sleep without dream- 

 ing of being blown up or frozen out. I 

 have at present about 3,500 feet of glass 

 and am adding some each year, and 

 would like to change to steam if I can 

 do it safely without keeping a night 

 man. L. C. B. 



By the use of automatic valves on 

 the gas main, to be controlled by the 

 boiler pressure or by thermostats in the 

 houses, both or either of which is per- 

 fectly practicable, you should be able to 

 maintain almost ideal conditions in the 

 greenhouses by means of steam installa- 

 tion. It will be wise to install an alarm 

 thermometer, to give a signal in case

anything should happen to throw the 

 gas off or on too heavily during the 

 night. This is simply a precautionary 

 measure and not an absolute necessity.

PIPING IN NORTH DAKOTA. 



I should like to know if a 24x42 

 Wilks hot water boiler would be large 

 enough to heat my two greenhouses and 

 residence. The greenhouses are built 

 end to end, and run east and west, with 

 the residence at the east end. The east 

 house, which is protected on the east by 

 the residence, is 20x31 and nine feet to 

 the ridge. The side walls are four feet 

 high, triple boarded, with two feet of 

 glass in the south side. The required 

 temperature is 60 degrees. The west 

 house is 20x32, and requires a tempera- 

 ture of 50 degrees; the other dimen- 

 sions and the construction are alike in 

 the two houses. There is glass between 

 the two houses and in the west end. In 

 the residence we heat only three rooms, 

 one 16x16 and the other two 8x16 each. 

 The outside temperature is often 20 de-
