As the Count knew nothing of coal as a fuel, the dimensions of his chimneys were based on the burning of wood, and made large enough for the purpose. The back of his fireplaces sloped forward, making a narrow opening for the smoke toward the front. This narrow opening extended up for a foot or more, and then dropped back square making a shoulder or shelf. If there is any back draught in such a chimney, the cold air strikes this shoulder and the hot air carries it up again at once, giving it no / / chance to get into the room and take the smoke with it. This little sketch (Fig. i) shows the method of construction. Three of our fireplaces were arranged to- gether, back to back, with one.
