Other kilns are cylindrical, with a low arch for a cover, but the principle of their operation does not essentially differ from that above represented. They all have openings for admitting air around the base, and for the escape of gases from above, all of which may be closed at will. G02. In another method, the kilns are of brick or stone made round and somewhat conical like a hay-stack, with openings on the side for filling and emptying, and air-holes for regulating the burning. They are of various capacities, but generally hold from 40 to 60 cords of wood. They are best built upon sloping ground, with doors on the upper side for filling, and at the bottom for removing the coal, and in both rectangular and conical kilns there is a further ad-.
