2-inch supply pipe as a main in each 

 direction from the cross aisle on the 

 plates of the side walls or on the pur- 

 lins, to the farther end of each house. 

 For the coils, use three 2-inch returns 

 on each of the outer walls of houses 

 1 and 3, which have six feet of 

 exposed glass. As we understand the 

 construction of the houses, there are 

 no partition walls, in which case it 

 will answer it a 2-inch main is run 

 each way on each of the inside lines of 

 gutter posts, with two 2-inch returns 

 on each side of these posts. There will 

 then be four 2-inch flows running in 

 each direction, with fourteen 2-inch re- 

 turns, there being five returns in the 

 middle house. 



Instead of using 2-inch returns, it is 

 preferable to use four 1%-inch returns 

 on each of the inside rows of gutter 

 posts. All of the returns should be 

 kept three feet above the floor of the 

 greenhouses. Were it not that the wa- 

 ter level of the boiler is so close to the 

 level of the greenhouse floor, one of 

 the returns might be carried in the in- 

 side walks. 



AMOUNT OF PIPE. 



^ We are sending a sketch of a green- 

 house, 25x85 feet. The side walls are 

 three feet of glass and three feet solid. 

 The south end is a salesroom, while the 

 north end is solid. The twenty-five 

 feet next to the boiler room is also solid. 

 I should like to install a new hot wa- 

 ter boiler and should like to know how 

 much pipe would be necessary and what 

 would be the best arrangement of the 

 pipes so as to have a temperature of 

 60 degrees in zero weather. The house 

 runs north and south and is well pro- 

 tected on the west side. The twenty- 

 five feet of space at the north end is 

 occupied by ground benches, the rest 

 by raised benches. Should the boiler 

 be below the ground level? What, at 

 present prices, ought this outfit to cost 

 installed! B. M. C— O. 



To heat the house itself, about 1,100 

 feet of hot water radiation will be re- 

 quired for 60 degrees and it is probable 

 that 100 square feet additional will be 

 needed for the salesroom. To provide 

 for this, as well as for the mains, the 

 'boiler should have a rating of at least 

 1,500 square feet of radiation, particu- 

 larly if soft coal is to be used. With 

 most boilers, this will mean a grate 

 containing about six square feet.

run the entire length of the two rooms, 

 placing one on each plate, a third two 

 feet below the ridge and the others 

 under the purlins. With each flow pipe, 

 supply three 2-inch returns, placing a 

 coil under each of the benches. If pos- 

 sible, it would be preferable to run 

 these through both rooms, but as it 

 may not be feasible to run these returns 

 through the north room, with its solid 



beds, it may be necessary to connect 

 these returns at the partition between 

 the rooms with a 4-inch return main 

 and carry this at, or near, the floor 

 level along the west wall of the north 

 room and join it to the boiler. 



If the coils from the south room can- 

 not be continued through the north 

 room, a 3-inch overhead flow should 

 be run through the 25-foot house and,
