WINDINGS AND GUIDES 159 



metrically-graduated spacing. That does determine 

 the outcome, but the subsequent spirals are wound 

 with increasing rapidity. Attention is directed also 

 to the fact that even the most serious mishap to any 

 part of the continuous winding, after the rod is com- 

 pleted, in no case necessitates rewinding the whole 

 joint, but only of the short interval between two con- 

 secutive solid windings, whether guide- or ferrule- 

 wrappings. 



All rod-windings are terminated finally by an " in- 

 visible-knot " ending. Before taking up the ques- 

 tion of guide- and ferrule-wrappings and their loca- 

 tion on the rod the detailed layout we will 

 describe several ways of making the invisible knot or 

 whip finish, which, after all, attain but one and the 

 same result. The winder soon will find that the 

 particular method which is most convenient will de- 

 pend both on himself and on the particular location 

 of a winding, or on other special conditions under 

 which he is compelled to make the fastening. The 

 mystery of this is the chief secret of rod-winding, 

 and it really is no " knot " at all, but a trick of 

 burying the end under the final turns in order at once 

 to get it out of the way and to keep the winding 

 from unwrapping. 



The illustrations that follow, Figures I to 9, show 

 windings made with a coarse thread instead of the 

 actual winding-silk, for the purpose of clearer delin- 

 eation.
