TO MAINTAIN AN EVEN TEMPERATURE IN YOUR GREENHOUSES, USE A 



Foster Pressure Regulator 



With this simple device attach(Hl to your steam main just inside the greenhouse the pres- 

 sure on the heating coils will be absolutely constant, anywhere from 1 to 15 pounds (whatcMM 

 the grower sets the Regulator at), no matter how the pressure on the boilers runs up and dow n. 



If the weather changes, or the sun heat varies, instead of turningr on more pipes, just turn a nut on the 

 Regulator, and get more steam, or less steam, at once. Made in sizes from %-inch to 10-inch just for this wori;. 



"The Foster Pressure Regulators which have been iastiiUed ia our greenhouses are giving 

 perfect satisfaction."— Peter B«lnberg, Chicago, March 16, 1910.

east wall is four and one-half feet kigh, 

 with three feet of concrete and eighteen 

 inches of glass. The west side will be 

 connected to a house with a 614-foot 

 wall. I wish to heat this house to 50 

 degrees in zero weather, in this Ohio 

 climate. I should like to use 4-inch cast 

 iron pipe for flows and returns. My 

 boiler is an upright. Will it be neces- 

 sary to tap it for 4-inch flows and 4- 

 inch returns, as it is tapped now for 

 only 21/^-inch flows and 2-inch returns? 

 The top of the boiler is eighteen inches 

 below the return pipes. C. A. B. 



While it is better to use smaller pipe 

 than 4-inch for hot water heating, it 

 will be possible to secure the temper- 

 ature mentioned in a house 15x60 feet 

 by using two 4-inch flow pipes and four 

 4-inch returns, provided the boiler is 

 sufficiently large. For a house of the 

 size mentioned, it will answer if each 

 flow is connected with the boiler by 

 means of a 2%-inch pipe, and each re- 

 turn by means of a 2-inch pipe. 



A SMALL VIOLET HOUSE. 



I have a small greenhouse in which 

 I intend to try growing violets. The 

 house is 8x15 feet, and five feet six 

 inches to the ridge. Can you tell me 

 of some way to heat it inexpensively? 

 The outside temperature in this part of 

 Colorado sometimes goes as low as 15 

 degrees below zero. C. A. 



The house can be readily heated by 

 using fifty square feet of radiating sur- 

 face, but just how the pipes should be 

 run cannot be definitely told without 

 knowing something of the arrangement 

 of the house. A simple method of pip- 

 ing for hot water, which would probably 

 give the best results for so small a 

 house, would be to use one liA-inch 

 flow pipe on each side of the house, with 

 two 1^-inch returns connected to each 

 flow. For the house menticned, a heat- 

 er rated for seventy-five square feet of 

 radiating surface will be desirable. 



UNSATISFACTORY PIPING. 



I have a greenhouse forty-eight feet 

 long, from east to west, by thirty feet 

 wide. It is ten feet high at tlie high- 

 est part, sloping eight feet to the north 

 and twenty-two feet to the south. The 

 west and north walls are wood. On the 

 north side of the house is a lean-to 

 eight feet wide, which is used as a 

 boiler room and workroom. The hot 

 water heater rests on a cement founda- 



Would, You Save One-Quarter of Your Coal Bill? 



INSTALL ■■ 



A Kitts Improved Hydraulic Damper Regulator. 



Florist Peter Crow^ Rose Place, Utica, N. Y., voluntarily writes:— 



'■ I am very much pleased to let you Icnow that the Damper Regulator I bought from you 

 last fall is by far the best apparatus for greenhouse purposes. I had my book-keeper compare 

 my coal bill of last with that of this year and I find v^a.viiig of one quarter the amount of 

 this year's coal over last year's; also the past winter was a great deal colder and longer than 

 the winter before. 



" There is another very good feature about the Damper Regulator, as it keeps a uniform 

 heat in all the houses at all times by putting on and shutting off pipes. And I find that my 

 Roses and Ferns did far better this winter than any winter so far, as the temperature was so 

 uniform at all times. 



" My reason for writing you is to let you know, and also to thank you for bringing my 

 attention to the Regulator, and I assure you I cannot speak too highly of this machine." 



Are not facts like these worth an 

 investigation ?

SuccesporA to the 

 John Davis Company 



No loss from sudden drops in 

 temperature if you use the 



Hughson Regulating Valve 



In connection with a steam heating plant. Carry 40 or 

 50 pounds pressure on the boiler and set the valve for 5 

 or 10 pounds— it will do the rest You'll be free from 

 worry next winter, if you follow this advice: " Install a
