 out it is twisted so as to inclose the tish securely. It can be used only 

 where the bottom is free from aquatic plants and other impediments.

towards the bottom, so that the small fish, which go towards the bottom, 

 cannot fall through. The four corners of the net arc fastened to two 

 hoops placed crosswise, which serve to keei) it extended. At tlic i)lacc 

 where the hoops cross each other it is, by means of a rope, fastened to 

 a pole r> to 7 meters long. When fish are to be caught with tliis net a 

 bait is jdaced in it and it is dipped into the water. 



{c) The hose-net. — This apparatns consists of a net 10 to V2 meters 

 long, which is very wide 

 at the top and, gradually 

 getting narrower, ends in 

 a pointed bag. This net 

 is only used in very nar- 

 row rivers, wdiere it cov- 

 ers the entire breadth of 

 water. The fish enter 

 through the wide opening 

 i\U{\ go up into the narrow 

 portion of the net, whence 

 they cannot retrace their 

 way, but where they are frequently crushed to death. To remedy this 

 evil,

 bles the hose-net. It differs from tiiis net by the fact that tiie bag is 

 kei)t extended by hoops. At the mouth a very large hoop is fastened, 

 and at certain intervals hoops follow each other, which gradually become 

 narrower, and keep the net extended, so the lish can move about in it.
