grate in the three boilers. We can get 

 a return, tubular, firebox marine boiler 

 of eighty horse-power, 5x12 feet, with 

 forty-two 2-inch flues. The grate of this 

 boiler is 4x5 feet. Will this boiler do 

 the work of the three we havet We 

 heat with hot water. J. N. C. 



If three boilers, with a combined 

 grate area of twenty square feet, will 

 heat the houses, there should be no 

 difficulty in heating them with one 

 boiler having the same grate area as 

 the three small boilers. Judging, also, 

 from the radiation in the houses, the 

 boiler will be of ample size. 



A GEBANIUM HOUSE. 



I am building a greenhouse for the 

 growing of geraniums and bedding 

 plants. It is 20x50 feet and four %et 

 to the eaves, with 18 inches of glass 

 in the sides. It is ten feet six inches 

 to the ridge. The walls are concrete. 

 If I run two 2-inch flows overhead in 

 the center, two feet below the ridge, 

 with a rise to the farther end of the 

 house, and then have them drop straight 

 down, each flow going into a manifold 

 and returning on the side walls with 

 three 2-inch pipes to the boiler, would 

 I get a good circulation and would that 

 be sufficient piping to heat the house in 

 this Pennsylvania climate! C. W. B. 



If 60 degrees is desired in a house 

 20x50 feet, with eighteen inches of 

 glass in each wall, about 450 square 

 feet of radiation will be needed, and 

 it will be best to use three 2i^-inch 

 flows and nine 2-inch returns. For 55 

 degrees, two flows and ten returns could 

 be used. 



It will be best to have the highest 

 point in the system near the boiler, and 

 if the expansion tank is attached at 

 that point, no air cocks will be neces- 

 sary. By giving the flow pipes a slight 

 fall, a better circulation can be se- 

 cured than when they run upward.
