A SMALL ILLINOIS HOUSE. 



, I am about to build a small green- 

 house, 21x25, for the purpose of grow- 

 ing bedding plants. The house will run 

 north and south. The south end will be 

 glass and there will be three feet of 

 glass in the sides. The height to the 

 ridge will be about thirteen feet. There 

 will be three benches. Please give me 

 Bome idea of how to pipe the house so 

 as to maintain a temperature of 65 de- 

 grees in this Illinois climate. 



J. G. W. 



To heat the house described, I would 

 run two 21^-inch flow pipes about two 

 feet under the ridge, to the farther end 

 of the house, where they should drop 

 down and each of them should feed a 

 coil of six 2-inch pipes, running from 

 the middle of the south end to the cor- 

 ners of the house and then along the 

 sides back to the boiler. By using a 

 generator it would be possible to sup- 

 ply both of the coils with one 2i^-inch 

 flow pipe, but I would not make any 

 other change. 



BOILEE CAPACITY UNCERTAIN. 



Please let me know how much green- 

 house area can be heated by a Hender- 

 son Thermo boiler, the fire-box of which 

 is 28x40 inches. I have three green- 

 houses. Two of them are each 20x80 

 and the other is 30x100. The two smaller 

 houses are twelve feet high in the center 

 and the larger one is fifteen feet high 

 in the center. The houses run north and 

 south. The smaller houses are south of 

 the boiler shed and the other house is 

 north of the shed. Let me know whether 

 the boiler mentioned will heat the three 

 houses to 50 degrees at night in zero 

 weather. At present I grow only sweet 

 peas, but next August I shall want to 



filant the houses with carnations. I am 

 ocated in northeastern New Jersey. 

 How many pipes will be required and of 

 what sizet J. G. 



Since only the grate area of the boiler 

 is stated, it is not possible to give a 

 definite answer to the question regarding 

 its efficiency for heating the three houses 

 described. I am not familiar with the 

 construction of the boiler mentioned and 



WHY TAKE A CHMICE? 



You can't know (at best you only think you 

 know) what the temperature is in your green- 

 houses, nights and during yx>ur absences, unless 

 you have

THCmMOMETCR 



Preseit price, $20.00; formeriy $2S.OO 



It has made thousands of dollars for many flor- 

 ists and may do as much for you. Your plants 

 must have'certain, steady temperature to do their 

 best. Use this thermometer and you will know 

 whether they are getting what they need. It 

 leaves a written record under lock and key.
