256 THE TRAMMEL NET. 



and is formed of three separate portions. The small 

 meshed twine netting is called the lint, and in a net 

 thus composed of three parts, the more flexible lint 

 hangs loosely between the two portions of the much 

 larger-sized cord meshes which are called the wallings. 

 These wallings are of equal length and depth on both 

 sides or rather before and behind the lint or lining 

 portion, which is always double the length and depth 

 of the wallings, whatever their length and depth may 

 be ; depending on the particular purpose or place for 

 which the net is intended. The meshes of the wallings 

 should be four times larger than the meshes of the 

 lint. This sort of net corked along the head-line, 

 and leaded at the bottom, is commonly used as a 

 stop-net. 



Hanging in the water like a drift-net to intercept 

 the passage of any passing fish, a scan or a draught- 

 net is pulled towards it from a distance, and any fish 

 flying from before the draught-net passes through the 

 walling, and forms by his momentum a bag or pocket 

 for himself in the looser lint of the net from which he 

 seldom escapes. 



When this net is used in a river it should be long- 

 enough to reach quite across it, from bank to bank, 

 and the water being disturbed for some distance both 

 above and below the trammel, both wallings come into 

 operation. 



The next net, and the last to be here figured and re- 

 ferred to is called a keer-drag, and is an effective 

 machine where the ground is smooth, for collecting 

 small fishes, and various other marine animals.
