In thisconstruction the usual arrangement of flat sheets supportedby stay bolts has been abandoned except in the front sheets. Details of butt-welded joint at mud-ring and door sheets. The side sheets, crown sheets and wrappersheets have been replaced by a series of semi-elliptic channel-formed sections riveted together with their flanges turnedaway from the fire. Stay bolts have been replaced by staysheets, A stay sheet is interposed between each adjacent setof channel sections and is securely held thereto by the samerivets which fasten these sections together. These stay sheetsare partially cut out or perforated through the water spacein order to afford ample opening through which the watermay pass to establish horizontal circulation.
