are separated from the alley by a barn. 

 The north two are for carnations and 

 mums and the south house is for let- 

 tuce. The boiler room is at the west 

 end of the lettuce house, and is thus 

 a distance of 354 feet from the frontal 

 house. The boiler will be five feet 

 lower than the floor of the frontal 

 house. 



The boiler room and the lettuce house, 

 in the new part of the range, are in 

 a direct line with the bedding plant 

 house, in the old part of the range, 

 and we want to run a supply steam line 

 from the boiler straight east to the 

 frontal house. Would this give us good 

 return circulation to the boiler without 

 the use of force? S. F. & N. C. 



Judging from the description given, 

 there should be no difficulty in heating 

 the houses. While the details are not 

 sufficiently definite to permit any posi- 

 tive assertion regarding the running 

 of the mains, the following should give 

 good results: 



For the new 200-foot carnation houses 

 take off a 3-inch main from the boiler, 

 and from it run a 2%-inch supply pipe 

 through feach house from the west to 

 the east end. For the coils use eight 

 1^/4 -inch pipes in each house and con- 

 nect all with the boiler by means of a 

 1%-inch return. 



To supply the other houses — the new 

 lettuce house and the old part of the 

 range — run a 4-inch main through the 

 lettuce house. At the east end of that 

 house take off a 2-inch supply pipe and 

 from it feed six l^iinch returns, to 

 heat the lettuce house. Then continue 

 the main pipe on through to the east 

 end of the bedding plant house as a 

 3-inch. For the carnation house, 42x 

 116, use a 2-inch supply pipe and con- 

 nect at the east end with fourteen 1%- 

 inch pipes. Arrange this same piping 

 also for the rose house, 32x116. In 

 the bedding plant house, 22x102, use 

 ten 11/4-inch pipes, with the same num- 

 ber in the propagating house. 



THIS HALF 



shows you the three times »>ack and forth Burnham Fire Travel that actually is three times 

 By three times, we mean three times in each half of the boiler— actually a six times travel! 

 you see. 



It's this wonderful travel that sifts out practically all the heat from the gases, making hot 

 coils and a cool chimney. 



And This Half 



shows that deep lire pot with its thick bed of coals and the deep waterways directly over the 

 hottest part. It is the space between these waterways that makes the cross fire channels 

 running from side to side of the fire chamber. It is these channels that lead to tho side flue 

 openings. It is these flue openings that prevent the burning gases from rushing to an outlet 

 at rear of boiler, making only the back sections really etlicient. Kvery Bumtuun Section 

 is equally efflolent. Got the word equally fixed in your mind. The Burnham is a 

 greenhouse boiler made for greenhouse work. Send for catalogu'

For the palm house run a l^/^-inch 

 main from the east end of the bedding 

 plant house to the south end of the 

 palm room and another to the north 

 end, over the doors. Then from each 

 end run eight 1%-inch pipes to the cen-

 benches. 



GREENHOUSE AND RESIDENCE.

 wish to put in a heating plant. I also 

 wish to heat four rooms in my dwelling, 

 which is about thirty feet from the 

 greenhouse. I want to have the boiler„
