The main column is 9 inches high, and each of the six faces is 2 inches. Cut out a piece of cardboard, of medium thickness, 9 inches by 12¼ inches (Fig. 378). Divide it into six parts 2 inches in width, leaving a flange ¼ inch wide at the end for fastening the column together. Make half cuts along the dotted lines. Cut out a door and windows, and two holes, G and H, ¼ inch square. Fold and gum together. The hexagonal column above the first platform is 2½ inches high, sides 2 inches; that above the second platform is 2 inches high, sides 1½ inches.
Before folding and gumming the top column, or lantern, together, windows must be cut out. It is easier to cut the windows out completely and gum the bars behind the openings. A door is cut just above the first platform as shown in the plate. The top of the lantern is a hexagonal pyramid 1½ inches high, edges 2 inches. To make this, the length of one of the sloping edges (as a' d' in Fig. 380) must be found.
Fig. 380
Fig. 381
Draw a line a b (Fig. 381) 2 inches long. This is one edge of the hexagonal base. On it make an equilateral triangle a c b. This is the same as triangle a' c' b' in Fig. 380. At c (Fig. 381) draw c d at right angles to a c; make c d equal to the height of the pyramid—namely, 1½ inches; join a d; this is the length of one of the sloping edges (a' d' in Fig. 380). With radius a d describe a circle (Fig. 379). Mark along its circumference the distance a b, six times; join a to b, b to c, etc., and join each point to the centre. Cut off the shaded portions, leaving a flange for fastening, and make half-cuts along the dotted lines. Bend and gum together.
The first platform shown in the plate is a circle of cardboard or wood, radius 3 inches. Holes are made round the edge.
To this the upper column is fastened by paper hinges, unless the columns have been provided with flanges at top and bottom. Glue match sticks or pieces of cane, about 1 inch in length, into the holes in the platform for railings, round which black thread may be tied. Now fasten the whole to the main column so that the sides coincide.
