 gular shape. After filing the knots, and straighten- 

 ing his strips, he planes down a half- 

 dozen on the pith side to but half the 

 full thickness wanted. The other 

 six strips, after receiving the same cross-section of dou- 

 treatment, he files crosswise on the 

 enamel side just enough to flatten this surface for a 

 glue joint; the plane will not bite efficiently on this 

 glossy, outside surface of the bamboo. When glued 

 together, each double or compound strip will pre- 

 sent on cross-section the appearance shown. The 

 further treatment of these double 

 strips is identical with that of simple

 of each strip, the knots are slipped or staggered as 

 well as when gluing up the completed strips into 

 joints. 



There is one situation where the expedient of 

 double-built joints is of practical advantage, and that 

 is in building butt- and middle-joints of very large 

 caliber as for salmon or salt-water rods. It also 

 will be the resort at any time when you desire to con- 

 struct a solid-fiber butt-joint and when a single thick- 

 ness of the stock on hand is scant for the purpose. 

 You also can employ this method in combining the 

 handsomer Calcutta bamboo on the outside, for
