Now mark on a piece of tin a circle four inches and a quarter radius, or eight and a half inches wide; cut this circle out. Now cut out a quarter of the circle ([Fig. 12]), bring the cut edges together, lap them a little, and solder the joint, so that it makes a small tin cone ([Fig. 13]). Put this on to the four points on the top of the chimney-tube, and solder those points into it securely, and your chimney will be finished and look like [Fig. 14]. This must be pushed into the hole at the top of the lantern.
