In some places a crow-foot bar is used, andtwo men working from ixiside the shell will break the boltsdown through the water space; in either case the bolts willhave to be drilled outside just the same, and all burrs re-moved with a gouge. \\illi the door sheet removed, it willbe easy to drop the two sides by working the back ends to-wards the center till there is sufficient space in the clear toenable front end to pass outside of flue sheet flange and dropto the floor. Fig. 3 is a side view of the front end. It will be noticedthat the smoke-box is butted to fronts end and held in place bya I by 8-inch wrought-iron ring. Before the flue sheet can beremoved it will be necessary to cut off the front section offront end, including this ring, for the reason that the internaldiameter of ring is less than outside diameter of flue sheet.
