Material: Colored cardboard 5 1/2 in. x 8 1/2 in.; paste, ruler, scissors, strips of paper 1/2 in. x21 in.

Place cardboard on the desk, with the long edge toward you.

One inch from the upper right-hand corner, on the long edge, make a dot; one inch from the lower right-hand corner, on the long edge, make another. Draw a line connecting the dots.

One inch from the upper left-hand corner, on the long edge, make a dot, and one inch from the lower left-hand corner, on the long edge, another. Draw a line connecting the dots.

One inch from the upper right-hand corner, on the short edge, make a dot, and one inch from the upper left-hand corner, on the short edge, another. Draw a line connecting the dots.

One inch from the lower right-hand corner, on the short edge, make a dot, and one inch from the lower left-hand corner, on the short edge, another. Draw a line connecting the dots.

Cut out the squares A, B, C and D, Fig. 1.

Place Fig. 2 on another cardboard 5 1/2 x 8 1/2, and outline the four corners. (Fig. 3.)

Make two lines in each corner 1-16 inch nearer the edges of the cardboard than the lines already drawn. Mark "Cover."

(Fig. 4)

Cut out the four smaller corners, and draw lines connecting-corners. (Fig. 5.) Place the ruler on each of the four lines, and crease with the point of one blade of the scissors.

Cut off 1/4 inch of cardboard from each side. (Shaded part of Fig. 5.) Now bend the sides into position and paste a strip of paper around the edge of the cover. (Fig. 6.)

Do the same with the other piece of cardboard to form the box. (Fig. 7.)

Note: A thorough lesson on the divisions of the ruler should precede this work.
