136 BRITISH IND USTEIES. 



constructed on the same principle as those I have 

 previously described as being used at Grimsby ; but 



in order that they may 

 offer less resistance to 

 the stream, their ends are 

 rounded off, giving them 

 a somewhat boat-shaped 

 appearance. This form is 



Harwich Cod-chest. unnecessary in the quiet 



water of the Grimsby fish- 

 dock, and the oblong shape there adopted is more con- 

 venient for economizing room, and entails less expense 

 in construction. 



A few deep-sea trawlers sometimes work from Har- 

 wich, and trawling for prawns is carried on along the 

 adjoining coast. There is also some fishing in the 

 Harwich river by means of a net called a " trim-tram," 

 very much the same as the Leigh shrimp-net, which 

 appears to me to be very superior for its purpose, and is 

 probably an improved form of it. The distinguishing 

 feature in the trim-tram is the presence of a triangular 

 wooden frame resting on the ground in front of the 

 lower beam, and it may answer the possible purpose of 

 keeping the mouth of the net upright, and turning aside 

 any rubbish which may be in front of the net; but 

 there is an obvious disadvantage in this frame disturb- 

 ing the shrimps and fish at some little distance before 

 they can enter the net. The average quantity of fish 

 carried annually by the Great Eastern Kailway from 

 Harwich in the last fifteen years is 2000 tons, and this 

 has principally consisted of cod.
