be distributed to do away with the very 

 annoying hot and cold ends which are 

 often found in greenhouses? J. B. 



The house 26x120^ if heated with hot 

 water at 180 degrees, should be pro- 

 vided with a 3 14 -inch main flow pipe 

 arranged to supply seventeen 2-inch re- 

 turns. The house 10x120 will require a 

 214-ineh flow pipe, returning the length 

 of the house through eight 2-inch re- 

 turns. 



Yes, it is quite possible to do away 

 "with the warm and cool ends of green- 

 houses. This can be more easily and 

 cheaply accomplished with steam than 

 with hot water, and also more easily 

 where the main flow is carried, to the 

 most distant end of the house under the 

 ridge than when smaller flow pipes are 

 used and arranged under the benches. 

 When steam is used and the main flow 

 is carried to the most distant end of 

 the house under the ridge and there di- 

 vided to return under the benches in an 

 adequate number of returns there is sel- 

 dom any trouble with uneven tempera- 

 tures, but with no other system of piping 

 have I been able to secure as even a 

 temperature. L. C. C. 



METHOD OF HEATING. 



I am planning to erect an even-span 

 house 30x100 in a sheltered location, 

 boarded on the north and with two 

 feet of glass on the south side. The 

 temperature required will be 50 to 55 

 degrees in the coldest Massachusetts 

 weather. The land is such that I can- 

 not sink a boiler more than four feet. 

 I have a sixty horse-power tubular 

 boiler, but I must dispense with a night

fireman. If I use a steam trap to re- 

 turn condensation could I get an ap- 

 pliance which would automatically ring 

 a bell in my sleeping room if the steam 

 pressure went below the point neces- 

 sary to operate the trap, or would you 

 advise me to have larger openings cut 

 in the boiler and turn it into a hot 

 water system? If so, how large open- 

 ings would be necessary? How many 

 runs of 2-inch pipe would be required 

 if hot water was used and how many 

 runs of 11/4 -inch pipes if steam was 

 used? E. W. 



Yes, it will be possible for you to ar- 

 range an automatic alarm to indicate 

 minimum steam pressure as you sug- 

 gest, but if you have only one green- 

 house of the size indicated to be 

 heated by a sixty horse-power tubular 

 boiler it would, in my judgment, be bet- 

 ter for you to plan a hot water system 

 rather than a steam system until you 

 have sufficient glass to warrant you in 

 employing a night fireman. The boiler 

 you have undoubtedly has a 4-inch con- 

 nection on top and 2^-ineh or 3-inch 

 connection for the return. If so it will 

 be ample for either steam or hot water. 

 If you use steam the main flow pipe 

 should be 214-inch and arranged to 

 supply eighteen l^^-inch pipes. With 

 hot water the flow pipe should be 3^4-

Indianapolis, Ind. — Mrs. Gunnar Teil- 

 mann, of Marion, Ind., is in the hospital 

 here, where she underwent a serious oper- 

 ation, July 6. She stood the ordeal well 

 and is convalescing as rapidly as could 

 be expected.
