materially increased, it can be used where the 

 rope is to pass through pulleys and small 

 openings. Good, stout wrapping cord should 

 be used for the whipping. A loop of cord is 

 laid along the end of the rope, as shown at A, 

 Fig. 337. The loop is then used to wrap the 

 rope, allowing the side of the loop to pass over 

 the end of the rope. After the rope has been 

 wrapped for a sufficient distance, the ends of 

 the cord are pulled tight and then cut off, -as 

 shown at B. 



Crowning the end of a rope 

 consists in unraveling it for a 

 short distance, usually 5 or 6 

 inches; then knotting the strands 

 and turnjng them back and weaving them 

 into the rope. This increases the size of the 

 rope end, but makes a very firm 

 finish. The strands are first 

 knotted as shown at A, Fig. 

 338. Then with the aid of a 

 pointed, smooth, hardwood stick 

 the loose strands are woven al- F i g . 7s 5. TWO 

 ternately over and under the half hitches ' 

 strands in the rope. When passed under 

 three or more strands of the rope in this 

 manner, the end of each loose strand may be 

 cut off. To prevent kinks and to make a 

 smoother finish, the loose strands may be 

 slightly untwisted as they are woven into the 

 rope. When finished, the crown should have 

 the appearance of D, Fig. 338.
