THE TRAMMEL. 223 



meshes or sheeting, between two tighter nets of larger meshes 

 called the walling. 



It is thus made and of the following materials : 



The twine known as the Shrewsbury thread is found to 

 answer better than any other that has been tried, as from its 

 fineness and pliability it meshes the fish remarkably well, which 

 a hard twine fails to do. 



The size No. 18 is preferred in the island of Guernsey, and 

 is manufactured by Messrs. Marshall & Co., Shrewsbury. 



A flax-twine used in Kent for drift Sprat-nets has also been 

 tried and approved of. 



The size of the mesh should be three inches and one-eighth, 

 and the depth forty- two meshes or eighty-four rows. 



Supposing the net to be eighty fathoms in length, when 

 mounted it must only occupy half this distance, namely forty 

 fathoms, and on every length of six inches of the roping four 

 meshes must be taken in the needle at once and secured. 



On each side of this fine netting is fastened a net with 

 meshes of eighteen inches in length when stretched tight, in- 

 eluding three knots, and of Salmon twine : these large meshes 

 are secured to the rope or rawling at distances of twelve inches 

 on the head and foot ropes, and being only half the depth of 

 the middle net leave a large amount of slack which allows the 

 fish to pocket themselves, as shown in the second engraving. 



Fig. 68, p. 224 represents a side view of the trammel when 

 set in the water, or as it appears when hung up to dry upon a 

 wall, the large meshes plainly visible crossing the smaller, which 

 being slacker fall down to the foot-line. As there is a walling 

 on both sides of the small mesh, the fish pocket themselves 

 when swimming from either side. Plain sheet-nets are used in 

 some localities, and are erroneously called * trammels.' At 

 others they are used with one walling only ; to be strictly a 

 ' trammel,' there must be three nets side by side. At Poole the 

 middle only is of three nets, the ends single sheets. Square 

 wallings originated, I believe, in Spain, but are now frequently 

 used in England. 



The cork required for the head-line should be cut two 

 inches square and three-quarters of an inch in thickness, from
