96 THE IDYL OF THE SPLIT-BAMBOO 



joint (it being understood that some ten to twelve 

 inches of handgrasp are included in this joint, in 

 the completed rod) ; the corresponding ferrule-half 

 of the second-joint projecting i% inches, leaves that 

 amount less than 40.79, or 39.665 inches, for the 

 wood length of the second-joint. The way that it 

 works out is shown in our next illustration. 



Going back now to our previous diagram, we 

 measure 39.54 inches from A, which gives B as 



. 6(, S 



Finding the joint wood-lengths io-foot rod 



the actual common caliber of the adjoining ends of 

 the first- and second-joints; measuring, once more, 

 39.665 inches from the point B, gives us C as the 

 remaining caliber wanted. We now know the length 

 of each of our bamboo-joints irrespective of the fer- 

 rules, and we know the diameters of the respective 

 ends of these joints or pieces of the rod, and can 

 proceed to set our metal grooved-mold accordingly, 

 using half of each of these diameters as the measure- 

 ments from bevel-edge to bevel-edge across the face 

 of the mold, in getting out the component joint- 

 strips. Of course we maintain the mold so set, by 

 tightening up the screws.
