on each of the sides of the foundation platform, cut a strip of cardboard twelve and one-half inches long, and three inches wide. Across the entire length of the strip draw lines half an inch apart, as I I ([Fig. 367]). Cross these short lines by a long line running lengthwise one inch from the top edge, J J ([Fig. 367]). Between this line and the upper edge draw another line, running lengthwise, a quarter of an inch from the line J J, as K K, [Fig. 367]. You now have a strip of cardboard twelve and one-half inches long and three inches wide. Across its entire length you have run two long lines, and across the entire width many short lines.
Begin with the Second Division
from one end of the strip marked by the short lines, and make a dot on the centre of the line K K ([Fig. 367]) where this line crosses the second division. L ([Fig. 367]) shows the dot.
Fig. 368.—Stand the box on one side.
The diagram [Fig. 367] is merely intended as a guide, giving only portions of the twelve and one-half inch strip you are making. Begin at the lower corner of the small division under L ([Fig. 367]) and draw a curved line up to L; draw another curved line from the opposite corner of the same division up to the same point. The two lines will
Form an Arch
as in M ([Fig. 367]). Skip one division and draw another arch on the fourth division in the same way that you drew the arch of the second division. In like manner draw an arch in the space between the lines K K and J J of every other division on the strip. This will make twelve arched divisions, leaving a solid division or pillar at each end of the strip and also between each opening. With the point of your knife-blade
