Greenhouse Heating. 



Those interested in the methods of 

 heating modern greenhouses should read 

 the description of Joseph Heaeock's new 

 place on page 26 of this issue. 



LEAK IN BOILER. 



There is a small leak in our boiler, 

 immediately over the fire. Do you 

 think cast-iron borings and sal am- 

 moniac would do the leak any good, or 

 what would you suggest! D. & J. 



If the leak is not too large it may be 

 possible to stop it by using either iron 

 filings and sal ammoniac, or litharge. 

 The latter should be stirred up in 

 glycerine, and after it has been applied 

 to the leak it should be burned oflf with 

 a torch. By making a number of appli- 

 cations a leak of considerable size may 

 be stopped. 



DEFECT IN HEATING SYSTEM. 



I am sending you a diagram of our 

 heating plant and should like to know 

 whether you can see any defect in our 

 system of piping. We are not getting 

 satisfactory service from our boiler, 

 which is supposed to heat 6,000 square 

 feet of glass in zero weather. We have 

 only 5,000 square feet of glass, as you 

 will see by referring to the sketch, 

 but we have difficulty in pushing the 

 boiler so as to heat the houses, though 

 we are located in southern New Orleans 

 and have no zero temperature to con- 

 tend with. We use soft coal and coke 

 for fuel. D. & J- 



The amount of glass is really some- 

 thing over 6,000 square feet, instead of 

 5,000 square feet as stated, as in esti- 

 mating radiation the total amount of 

 glass exposed is considered. 



The sketch shows two houses 15x100 

 feet, and one house 20x100 feet. In 

 each of the 15-foot houses there are two

2%-inch flows, three and one-half feet 

 below the plates, and each flow supplies 

 one return underneath. In the 20-foot 

 house there are three flows and the 

 same number of returns. It is evident 

 that both flows and returns are below 

 the top of the heater and the best re- 

 sults cannot be secured with the piping 

 so arranged, unless a closed system is 

 used. Even better results can be ob- 

 tained by carrying the flow pipes at 

 the level of the plates and raising the 

 returns to within a foot of the bottom 

 of the benches, or, if on the walls, plac- 

 ing them just under the flows. 



A PARTITIONED GREENHOUSE. 



Will you kindly give me some advice 

 about the heating of my new green- 

 house f It runs north and south and is 

 sixteen feet wide. It has a total length 

 of fifty-eight feet, but is divided into 

 two rooms. The north room, eighteen 

 feet long, is for violets; the south room, 

 forty feet long, is for bedding plants, 

 geraniums, etc. The larger room is 

 three and a half feet high at the sides 

 and six and a half feet high at the 

 ridge. The smaller room is two feet 

 high at the sides and five feet at the 

 ridge, and the walk is sunk eighteen 

 inches below the ground level, so as to

provide room in walking. There is no 

 glass except in the roof. 



I intend using a Wilks upright boiler, 

 20x36. I thought of building a small 

 boiler shed at the south end, and would 

 prefer having the boiler on a level with 

 the greenhouse, if expedient, on account 

 of the ground being rather low, but I 

 shall dig a pit if it is really necessary. 

 Kindly give me definite plans for the 

 piping, so as to have a temperature of 

 42 to 45 degrees in the violet house and 

 45 to 50 degrees in the other room. I 

 am located in the western part of New 

 York state. C. G. J. & S. 



If the returns are not above the top 

 of the boiler it is desirable to use a 

 closed system, by putting on a riveted 

 boiler-iron tank, with a water gauge on 

 the side and a safety valve at the top. 

 This will make it possible to heat the 

 water considerably above the boiling
