I expect to build two houses, each 18x70. "What size of boiler will be needed to heat these properly, in this Ohio climate? I expect to heat with hot water, as there will be an opportunity for a good return system, with the boiler in a basement on a hillside. I will also have another building, 12x60, in front of the greenhouses, and will use it as a workroom, store and experi- ment room. In this building there will be about 400 feet of glass, in the sides only. G. L. N. The inquiry is far from being clear enough to warrant a definite reply. The temperature which is desired is not stated, and the coistruction of the greenhouse walls and the amount of glass they contain are not given. If the walls of the greenhouses are well built and contain no glass, it should be pos- sible to maintain a temperature of 60 degrees in them with 1,000 square feet of radiation. One can only give a guess at the amount of radiation required in the other building. If the walls are ceiled or plastered inside and 400 square feet of glass is the entire amount in the building, it should be found an easy matter to heat it to 60 defrees with 250 square feet of radiation, provided the walls are only eight or nine feet high and there is a ceiling at about that height. To furnish the radiation for both this building and the green- houses it would be advisable to have a hot water boiler rated at about 1,500 square feet of radiation. THE FUEL MABEET. The last few days have brought the first real winter weather of the season over a large part of the country—the part in which greenhouse fuel require- ments are heaviest. It has increased consumption while it has, in some sec- tions, more or less impeded the move- ment of cars by the railroads. The sit- uation at Chicago is much the same as elsewhere and the
