GLAD TO PBmT ANSWERS. 



It would be interesting to others, no 

 doubt, as well as myself, to see in the 

 department of Greenhouse Heating 

 statements showing the number of tons 

 of coal used per 1,000 square feet of 

 glass in heating, by a number of repre- 

 sentative growers. This should show 

 the kind of fuel used and the tempera- 

 ture maintained. The last two winters 

 I used between nine and ten tons of 

 soft coal screenings (slack), each win- 

 ter, night temperature averaging 50 de- 

 grees. I am inclined to think this too 

 much, and am wondering how it com- 

 pares with others. I use both hot water 

 and steam, the steam boiler being used 

 only as a helper in extreme weather or 

 ,when raising heat in the mornings.

PIPINa AtTD BOILEB. 



Kindly advise me through your heat- 

 ing department as to the best steam 

 system and how to pipe four houses so 

 I may obtain 65 degrees to 70 degrees 

 in zero weather. The houses are 22x95 

 feet; height to ridge, fourteen feet; 

 gutters, seven feet; also size of boiler 

 you would recommend. Location, a 

 Chicago suburb. E. F. G. 



For each of the houses run a 2-inch 

 overhead main about two feet below 

 the ridge, and at the farther end con- 

 nect with the coils, using 114-inch pipe. 

 Just how many coils there should be 

 will depend upon whether beds or 

 benches are to be used, the number of 

 each, and the use to which the house 

 is to be put. About ten 114-inch pipes 

 will be required. If there are four 

 raised benches, two pipes may be located 

 under each of them, and the others on 

 the walls. If there is any exposed 

 glass in any of the walls, use one addi- 

 tional return for every two feet of 

 glass. Shut-off valves should be placed 

 in the connecting pipes at both ends of 

 e ?h coil. 



PLANNING AN ADDITION. 



Enclosed you will find a rough sketch 

 of my grounds, on which I intend to 

 .build some more greenhouses. The pres- 

 ent house is 18x50. The boiler shed is 

 at the west end and throws too much 

 shade on the house. Would you advise 

 me to run the new house, 23x120, west 

 from the shed, as shown in the sketch, 

 so that the shed would be at its east 

 endf I should like to keep the boiler 

 shed about where it is, so as to have it 

 as near the dwelling as possible. There 

 is a stable about seventy-five feet north 

 of the shed. Would you advise an 

 equal-span house or one with a short 

 span to the south? I intend to plant 

 the house with carnations and bedding 

 plants. Are there any steam boilers 

 that can be left for any length of time 

 without attention t E. W.

running east and west, with the shed 

 at the west end of the small house and 

 at the east end of the proposed house, 

 which seems to be as good a plan as 

 can be used, unless the small house is 

 soon to be taken down or extensive ad- 

 ditions are to be made in the near 

 future. In either of these cases it 

 would be better to plan for the new 

 house, or houses, without much regard 

 for the present house. A new range 

 could be built running north and south, 

 with a shed at the north end, near the 

 stable referred to. If this is done it 

 will be best to have even-span houses, 

 and they are generally preferred even 

 for houses which run east and west. 



While it is always best if steam 

 boilers can have frequent attention, if 

 they are of ample size and have a large
