Ilowever, a boiler rated for ]25 horse- power will be amply large except when the weather ajjproaches zero, and, un- less the number of the greenhouses is to be increased, we would recommend the installation of two boilers of 125 horsepower each, planning to hold one in reserve, except in severe weather, to be used in case of accident to the other boiler. Although one of these boilers will not be quite as large as will be de- sired for carrying the radiation with the temperature at zero and below, it will do so with a little extra attention in case of a breakdown of the other boiler, and in ordinary weather it can be operated much more cheaply than the larger boiler. QUANTITY OF COAL CONSUMED. I am of the opinion that I am using more coal than I ought to use in heating my establishment, which comprises the following buildings: One greenhouse 18x85, with two feet of glass in the sides and a 10-foot gable; another greenhouse 24x110, with four feet of glass in the sides and a 12-foot gable; a packing room 12x24, with 9-foot stud- ding and a quarter-pitch roof; a resi- dence, of which I heat the first story, which is nine feet high and contains five rooms, 14xlG, 12x14, 12x12, 14x15 and 10x11, and a bathroom 5x9. I have an American hot water boiler, rated at 3, 750 feet. Please let me know about how much mine-run soft coal should be re- quired each season to heat this place, running the greenhouses with a temper- ature of 50 degrees at night and 60 de- grees in the daytime. C. J. S.—Pa. So many conditions affect the coal con- sumption that what might prove ample in one season might come far short in another. The construction: and exposure of the greenhouses will have much to do with it, and the weather might be much more severe one year than another. Careful firing will have much to do with the economy in coal consumption. We would think that under good aver- age cond
