The fuel that is used will depend upon the type of furnace and the relative prices prevailing for different kinds. Recent developments in oil heating bring this fuel in close competition from the standpoint of economy with coal or coke. Oil is particularly adaptable as a source of fuel in homes in the country since tank trucks can readily deliver oil to the home owner. Improvements in securing the maximum efficiency from all types of fuel are being developed continually; and there are now on the market furnaces, using anthracite or bituminous coal as fuel, which offer many advantages that were unknown to older types. _Fireplace Construction._--An open fireplace where wood can be used as fuel is a great source of satisfaction and pleasure, as well as a comfort, in country homes. Wood of proper length for fireplace burning can be readily secured in the country and there is ample room for storing it. Where the house is small in size, such wood fires can be used for heating the house satisfactorily in spring and fall and can be used to supplement other types of heating when desired. No country home can be considered complete without a fireplace. The comfort and homelike atmosphere that it gives make it a general asset for the enjoyment of the family circle. Fireplaces should be constructed so as to insure a good draft with a maximum of heat radiation. It is desirable to build in the fireplace flue a damper which can be open when the fire is burning and can be shut when it is desired to keep heat from escaping from the room via the chimney. It is also a convenience to have a trap opening placed in the back of the fireplace on the floor so that ashes may be removed in this manner, eliminating the labor of carrying them from the fireplace. _Sewerage of Farm Homes._--All wastes from the farm home coming under the term of sewage should go direct to a septic tank. Here the sewage is held in a quiet state for a period of time, and through bacterial processes, the organic matter is destroyed. A septic-tank installation consists of four parts: first, the house sewer from house to tank; second, the sewage tank, consisting of one or more chambers; third, the sewer from tank to distribution field; fourth, the distribution field where the sewage is distributed, sometimes called the absorption field. Plans for sewerage construction may be obtained from state and local boards of health and from federal health and agricultural agencies.
