THE STAND-SUMP. 207 



There is, for instance, the Stand-sump, which, as the 

 name implies, is always stationary. It is square, and com- 

 posed of rough boards, nailed transversely to stout uprights 

 at the corners. The lowermost ends of these uprights 

 extend twelve to eighteen inches beyond the Sump itself, 

 and serve as feet for it to rest upon. It is needful thus 

 to raise it from the ground, especially in running water, 

 as the mud and slime would otherwise find its way into the 

 interior, and thus foul the water to the injury of the fish. 

 The top is boarded over, with the exception of an opening 

 for the introduction of a hand-net. Pretty large holes are 

 bored, about six inches apart, as well in the bottom as the 

 sides; and should the Sump be intended for small as well 

 as large fish, as is often the case, these holes are guarded by 

 pieces of stout wire, placed crosswise over them. 



The Sump in question is placed between four stout up- 

 right posts fixed in the ground, the space between being just 

 sufficient for its reception. It is suspended by hooks and 

 chains, that it may be raised or lowered, as the water rises 

 or falls a necessary precaution ; for should the lid lie 

 beneath the surface, the fish, from the want of atmospheric 

 air, are suffocated. The Sump ought to be placed in 

 running water ; for should there be no current, that portion 

 of the water enclosed within it would, from the presence 

 of a multitude of fish, soon become unfit for respiration. 

 If running water is not to be had, the Sump must be 

 placed where the bottom consists of sand or stone. In 

 shallow water, with a grassy, muddy, or clayey bottom, no 

 fish, unless perhaps the Crucian, the Tench, or the Eel, can 

 live. 



Another kind common in Sweden is the Slap-sump
