or grooves; so that each hair may pass through the quill, 

 and by the side of die cork, with some little resistance. 



The knot, which will thus be on the outside, beyond 

 the cork, should be turned round between the finger and 

 thumb ; by which means the hairs, coming like so maliy 

 rays from die edges of the cork, will begin to twist in the 

 most regular even manner, and will be gradually drawn 

 dirough. 



The person twisting the hairs should be careful to ob- 

 serve when the further ends of the hairs are about to come 

 through the grooves, which he may easily perceive, and 

 should then grasp what he has twisted close to die cork ; 

 then drawing out the residue, tie the ends, as in the first 

 instance : but, in order to keep the twists correct, he 

 should, as he proceeds, pass die line round his hand, so 

 as to coil it up in a small ring. 



This being done, he should lay every length, so soon as 

 made into a coil, in a cup of water, to let it soak -, after 

 about half an hour, some of the hairs will probably snarl, 

 or appear to gather, or shrink, in die twists. The lengths 

 in which such snarls appear must be untied, and be twisted 

 ,3! second time, after the hair has been dried. 



This process will all be seen in Plate I. where, in 

 Fig. 3, A, is the quill, B, the cork plug, c, the knot, and 

 d, d, d, d, the several hairs which form the length, or link, 

 passing through die quill 5. being pressed diereto, at equal 

 distances, by the cork. 



Any number of hairs may be dius twisted far better than 

 In the common way, and as regularly as by any machine : 

 though some on a goo,d plan, are sold at the tackle shops. 

 As the grooves may be made so as to allow twists of two, 

 three, or four hairs each, to pass, links may be made of
