230 Fly-rods and Fly-tackle. 



and the shoulder formed within is removed by a reamer. 

 No shoulder should be allowed in any joint at the edge 

 of a ferrule ; that is, there must be no abrupt change of 

 diameter between the part of the joint within and that 

 without the ferrule. Nor should the slightest scratch 

 running around the joint be permitted there, or, indeed, 

 elsewhere, for the joint is much weakened thereby and 

 thereat just as a few nicks with a cold chisel weakens a 

 bar of steel. 



When these sizes of ferrule are used with ash and 

 lancewood, or hickory, or ironwood, the rod, exclusive of 

 tip, should be divided into two equal portions, very near- 

 ly, to give the best result. These, and the sizes given 

 under the head of Bethabara in the preceding chapter, 

 will furnish as precise information as it is in my power 

 to give. If they are followed, it is not believed any error 

 can result beyond correction by local readjustment of the 

 taper. But if ignorance of the length and material you 

 propose to use, and the style of action you may prefer, 

 render it impossible precisely to define the diameters you 

 should employ, there are some other points in reference 

 to your ferrules which I most earnestly recommend to 

 your attention. 



First, your ferrules should by no means exceed the 

 lengths already given. You may even reduce them one- 

 eighth of an inch with profit, if your fitting is tolerably 

 good. The male ferrules to correspond should not exceed 

 butt ferrule, uniting same to handle, 1 finches; larger 

 end of middle joint 1-^- inches; tip has been already given. 

 Why you are thus advised will appear in discussing the 

 following points. 



Second, shun the dowel-pin and its socket.
