I expect to build two greenhouses, each 12x50. There will be one foot of glass in the side walls of one of the houses; the other house will have glass only in the roof. What will be the best way to heat the houses? The coldest weather we have here is about 16 de- grees below zero. The house with glass in the walls will have raised benches and will be used for genpral purposes. The other house will have solid beds. What will be the best size of pipe to use and what will be the best way to arrange it? Will an upright boiler of ten horsepower be suitable for the houses? Will it be better to install a hot water or steam system? T. L.—Utah. For houses of the size mentioned, it will be advisable to install a hot water plant. An upright boiler can be used, provided it can be so located that the top of the boiler will be lower than the returns. However, a boiler rated for 750 to 800 square feet would suffice. To maintain a temperature of 60 de- grees in the house containing solid beds, we would run a 2-inch flow pipe upon each plate, giving a fall of one inch in fifteen feet, and connect each flow at the farther end of the house with three 2-inch or four li^-inch return pipes. Each c_oil should then be connected with the boiler by a 2-inch return main. For the house with raised benches, which has one foot of glass in each side wall, we would use one 2%-inch flow pipe, carrying it a foot or so below the ridge, and connect with eight 2-ineh re- turns, located under the benches.
