There are 6,500 feet of glass in tlio houses, which are heated to a tein|K'rature of 50 de- grees at night. As we are changing from steam to hot water, we are at a loss to know what kind of fuel to buy, and should like some information on the subject, especially a comparison of costs of soft and hard coal. We are advised by Lord & Burnham Co. to use hard coal in their boilers, but we have always used soft coal. Hard coal, egg and pea, costs about $13 a ton delivered and soft coal costs about $ How much soft coal and how much hard coal would be need- ed for an average winter? Would the consumption of hard coal be enough smaller to somewhat nearly equalize the ilifl'erence in costs, or would the only advantage be the ease of firing? If we purchase hard coal, is it a good plan to use egg and pea in combination, the pea for quick firing and as a bank over the egg? If so, how many tons of each should we purchase for the winter's sup- ply? F. G.—N. Y. So much depends upon the quality of the coal, especially if it is soft coal, that we cannot give a definite reply to your <luestions. At the prices mentioned, if both are of good quality, we should con- sider the soft coal the cheaper, but in most sections soft coal sells for from $9 to $10 per ton, if of good quality. Hence, we judge that the soft coal men- tioned is not of the best and may prove to be the dearer. Since soft coal requires a grate con- siderably larger than hard coal requires, it is advisable to use a boiler rated at nearly twice the actual radiating sur- face. As near as we can estimate from the data given, about 1,650 square feet of radiation will be required for the four houses. This means that to use soft coal a boiler rated for 3,300 square feet of radiation will be required. We are not advised regarding the rating of a W-3G-6 boiler.
