If there is no glass in the side walls, 

 one of the returns may be omitted. 



For heating with hot water, I would 

 use three 2 ^^ -inch flow pipes and 

 twelve 2-inch returns, or two flows and 

 thirteen returns, arranged about the 

 same as for steam. One flow may be 

 placed upon each plate, and if three 

 are used the third pipe may be under 

 the ridge. If the 1%-inch pipe is on 

 hand, it may be substituted for the 2- 

 inch as returns, provided a mercury or 

 other pressure system is installed. In 

 ordinary winter weather even the lYz- 

 inch pipe will suffice to give the tem- 

 perature desired and, since the water 

 in the pipes can be raised even above 

 the boiling point by placing it under 

 pressure, there will be no difficulty 

 about maintaining 60 degrees in the 

 coldest weather. The radiation is fig- 

 ured at 60 degrees, as requested, al- 

 though a temperature of 50 to 55 de- 

 grees is all that is required for growing 

 carnations. 



PIPING FOR CUCUMBER FBAMES. 



I have two frames, each 6x50 feet, 

 eighteen inches high in front and 

 thirty inches high at the back. They 

 are used for growing early cucumbers. 

 During the winter no heat is needed in 

 the daytime, but frequ'ently the tem- 

 perature at night goes as low as 33 

 to 36 degrees. What hot water piping 

 would be needed for the two frames, 

 here in southern California, to keep 

 them at the proper temperature? 

 Should there be any piping underneath? 

 There is a 3-foot walk between the 

 frames. W. J. M. — Cal. 



If a little bottom heat can be pro- 

 vided for the frames, it will hasten the 

 growth of the cucumbers. Under the 

 conditions mentioned, I would run a 

 2-inch flow pipe on the back of the 

 frames, about six inches below the 

 glass, and connect this at the end of 

 the beds with two 2-inch returns, the 

 top of which should be about six inches 

 below the surface of the soil. In case 

 bottom heat is not desired, the neces- 

 sary ni^ht temperature may be secured 

 by running one 2-inch return pipe on 

 the front wall of the beds.
