ferns, pot plants, etc. The climate is 

 mild here. The temperature rarely goes 

 below 15 degrees above zero. I should 

 like to maintain a temperature of 55 

 degrees in the coldest weather in the 

 larger houses, and 65 to 70 degrees in 

 the smaller house. Will you please tell 

 me how to pipe these houses? If the 

 size of the boiler is unsatisfactory, I 

 can either enlarge or reduce it. The 

 flows and returns on this boiler may be 

 either 2 1^ -inch or 2-inch. How low 

 should the boiler pit bef 



W. H. D.— Ore. 



"Without some knowledge of the way 

 the boiler is constructed, it is not pos- 

 sible to estimate its rating, but I should 

 consider a boiler having a firebox 28 x 

 50 inches amply large for heating the 

 houses described and able to heat them 

 economically. 



I should run a 4-inch flow pipe to the 

 south house, and with it supply three 

 2%-inch flow pipes. One should be 

 upon each plate, and the other under 

 the ridge. Connect each flow pipe at 

 the west end of the house with return 

 coils of 2-inch pipe. Three pipes will 

 be required in the middle and south 

 coils, and two for the coil on the north 

 wall. 



In the middle house only two flows 

 will be required, and each of these 

 should supply a coil containing four 

 2-inch returns. For this house the main 

 flow and return pipes need not be 

 larger than Si-^-inch. 



To heat the small house to 65 degrees, 

 run a 2-inch flow on each wall plate, 

 and connect each flow with a coil con- 

 taining four 2-inch returns. If 70 de- 

 grees is needed, use 2% -inch pipes for 

 the flows and five returns in each coil. 



If the boiler has no openings larger 

 than 2%-inch, it will be necessary to 

 run flow and return pipes of that size 

 from the boiler to each house. I should 

 prefer not to use flows and main returns 

 smaller than 2%-inch for an open tank 

 system; if the openings are only 2-inch, 

 I should still use 2i^-inch pipes and re- 

 duce them at the heater. If 2-inch 

 flows and returns are put in, a mercury 

 generator should be used. If possible, 

 the top of the heatei* should be below 

 the level of the returns. 



PAETLY FOR PEOPAGATING. 



We are building an additional green- 

 house, 12x126, which eventually is to 

 be used only as a propagating house, 

 but will at first be used for general 

 purposes, such as propagating and 

 growing pot plants, etc. There will be 

 a 3-foot bench along the south wall, 

 and a 5-foot bench with a walk on each 

 side of it. We intend to use the 3-foot 

 bench for propagating only. Will you 

 please give us instructions about the 

 piping of the house! 



J. G. W. & S.— 111. 



The temperature desired for the 

 house is not stated, but for most plants 

 60 degrees will answer and this may 

 be secured by running a 2i/^-inch flow 

 on the plate over the 3-foot bench and 

 another about three feet under the 

 ridge, with three 2-inch returns under 

 each of the benches. In order to se- 

 cure bottom heat for the propagating 

 bed, the sides should be partly boarded 

 up. Later, when both beds are re- 

 quired for this purpose, and especially 

 if more heat is desired, one flow and 

 two or three returns may be placed on 

 tho other wall.
