taining thirty inches of glass and thirty 

 inches of concrete. The temperature de- 

 sired is 55 to 60 degrees. Each house 

 has two side benches, with a solid bed 

 in the center. 



From the sizes of pipe ordered, it is 

 inferred that the idea is to use 3-ineh 

 flows and 2-inch returns, wliich will be 

 all right. 



For each house it will be advisable to 

 use two 3-inch flow pipes, placing them 

 cn'the side wall plates and giving them 

 a slight downward slope. At the farther 

 end of the houses connect each flow pipe 

 with a coil of five 2-inch returns on the 

 outside walls and four returns on the 

 inside walls. 



This will only require about 1,800 feet 

 of 2-inch pipes, and good results can be 

 obtained with 1,600 linear feet. If 55 

 degrees will suffice, when the tempera- 

 ture is 10 below zero, the number of re- 

 turn pipes in each house can be reduced 

 to seven, which would require only 1,400 

 feet of 2-inch pipe. 



The boiler is am2)ly large to heat the 

 two houses. 



rOR CONNECTING HOUSES. 



Will you kindly give the heating re- 

 quirements for two greenhouses, one 

 12x40, six feet at the plate, nine feet 

 at the ridge, thirty-six inches of glass in 

 side walLs and glass in the ends; the 

 other, annexed, 7x40 feet, six feet at 

 the plate, nine feet at the ridge, thirty- 

 six inches of glass on side wall and the 

 end glass? I have a good deal of 2-inch 

 pipe I should like to use. Temperature 

 to be maintained, with hot water, is 60 

 degrees in the large house and 45 or 50 

 degrees in the small house. What rat- 

 ing should the boiler have?

A greenhouse 12x40 feet and with 

 th?ee feet of glass in each side wall can 

 be heated to 60 degrees by using three 

 2-inch flow pipes and six 2-inch returns. 

 Place one of tlie flow pipes on each of 

 the side wall plates and the other two 

 feet below the ridge, giving them a 

 slight slojjc. Two returns should be 

 placed on each of the side walls and the 

 other on the inside legs of the benches. 



In the other house use a 2i^-inch 

 overhead flow and four 2-inch returns. 

 If preferred, two 2-inch flow pipes may 

 be used.
