I have one house, 22x^49 feet, and to this house have added a lean-to, 9Vjx40 feet, which is heated from the main heating system. I have only one 3-inch flow below the ridge and eighteen 2-inch returns under the benches, with a good circulation. I think there is too much bottom heat and not enough above. The walls of the greenhouse are seven feet high; three feet of the walls consists of cement, board and paper, but the cement is cracked. I had my chimney enlarged, but it seems to have done no good. Would it bo better to have one flow on each plate? My boiler burns Pocahontas coal, but when the tempera- ture goes down to 20 degrees below zero it can hardly hold the temperature in the house at 50 degrees. (J. J.—la. Without a definite statement regard- ing the amount of glass in the side walls, it is impossible to give anything but an approximation regarding the amount of radiation required in the house described. Except for the lean-to, the boilat-and radiation should be able to hgnt the house. While the one 3-inch flow p\pe will give good results, it would be advisable to run one 2J/^-inch main on each wall plate, and the 3-incli pipe three feet below the ridge. If there is no glass in the side walla, it should be possible to carry a temperature of 60 degrees by using three 2i/^-inch flow pipes and twelve 2-incli returns. To heat the lean- to, it would be advisable to run a 2V2- inch flow pipe along the side wall near the ridge, and with it supply a coil of four 2-inch returns under the outside bench.
