Wood has certain advantages as a fuel, which many people nowadays have not considered. Wood is clean and free from disagreeable dust; it produces little smoke or soot when properly burned. A cord of hardwood leaves only 60 pounds of ashes, while a ton of hard coal will make 200 to 300 pounds. The wood ashes, moreover, have fertilizing value. Wood begins to burn at a comparatively low temperature, so that a wood fire is easy to start and can be maintained at a lower ebb than a coal fire, when only a small output of heat is needed. For cooking, a wood fire need not be kept burning so long as a coal fire and is less likely to overheat the kitchen in warm weather.
