and G H bisecting the angles already made. 

 With the point of intersection as centre, draw 

 a larger circle A C H, of about two inches 

 diameter, and a smaller one of about half an 

 inch diameter. If this is done with compasses, 

 the point of the leg must not be allowed to 

 make a hole in the paper at the centre. To 

 avoid this, a small flat piece of indiarubber 

 or tin or leather may be laid on the point where 

 the lines intersect, and the leg of the compass 

 can be placed upon it. When the circles are 

 marked out, draw lines in the position of the 

 dotted lines on the diagram. 



Now, with scissors or penknife, cut round 

 the larger circle. Then cut down the thick 

 lines, as far as the smaller circle, and from the 

 inner end of each cut make another cut half- 

 way to the inner end of the next cut. The 

 triangular flaps, E K L, and the others like 

 it, are now to be folded up so as to slope at 

 an angle of 45 to the table. This can best be 

 done by placing over the radial part which is 

 to remain unbent, K P D L, a flat ruler, in 

 the position M K N O, with its edge along 

 the dotted line K L. Holding this edge firmly 

 down, put the end of a table knife under the 

 flap E K L, bend it up, and press it with the 

 back of the knife-blade against the edge of 

 the flat ruler, so as to produce a sharp crease 

 along the dotted line K L. Leave the flap 

 sloping up at an angle of about 45. Bend
