Carefully find the exact center of the' 

 bridle loop and tie a loop knot there. 

 This settles for all time the point of 

 attachment of the flying string. This 

 kite flies higher than the Malay kite, 

 when bridled as described. By moving 

 the bridle back carefully, a point can 

 be found where the kite will fly low and 

 pull like a mule. 



The next t>pe is the square box. It 

 is shown in Fig. 21. 



The directions for the Blue Hill box 

 practically co\-er this, except the bracing. 

 For this case place the hardwood strip 

 vertically, glue and brace as before, with 

 the differences shown. Cut the tvs'o 

 holes side by side in the hardwood strip. 

 Glue the spreaders to the side ribs, cut 

 the shoulder on them at the right 

 length, and spring into the holes. 

 Bridle with a single string tied at the 

 f)oint where the inner edge of the cam- 

 bric of one end crosses one stick. When 

 knocked down this kite will lie flat. 



The Malay Box Combination

described for the Malay. When put 

 together it appears as shown in Fig.

 Malay kite. Fig. 24. 



Make the bowstring stick so it can be 

 dismounted, cis described for the Malay. 

 This kite is a beautiful flyer, and always 

 attracts much attention when in the air. 

 Three of these this size are all that can 

 be safely handled at one time. This 

 kite will knock down flat by removing 

 the bowstring and bow. This kite, as 

 described above has about 2,2 ft. of sail. 



The Tetrahedral Cell 



This kite is the invention of Professor 

 Alexander Graham Bell, and is a scien- 

 tific wonder. To begin with, a tetra- 

 hedron is a solid geometrical figure 

 made by four surfaces, each of which 

 is an equilateral triangle, all of these 

 triangles being of equal size. A tetra- 

 hedral cell kite cuts out tvvo of these 

 triangles. The remaining triangles are 

 the flying planes. In its simplest form
