206 NATURALIZATION OF FISH. 



used to the salt water, do nevertheless delight 

 much more in the fresh ; quoting the salmon and 

 the smelt, I doubt, he says, there hath not been 

 sufficient experiment made of putting sea fish 

 into fresh water ponds and pools ; it is a thing of 

 great use, for so you have them new at a great 

 distance; besides, fish will eat the pleasanter, 

 and may fall to breed : " such was the prophetic 

 eye of him who did not reject experiment. Why 

 is it rejected now? says Dr. M'Culloch. 



Mr. Arnold, of Guernsey, has in his lake, of about 

 four acres, chiefly supplied with fresh water, many 

 sea fish ; all have improved in quality, and propa- 

 gated. The lake, which before was worthless, only 

 producing a few eels, now yields a large rent. The 

 bottom of the lake is various muddy, rocky, and 

 gravelly, and since the introduction of sea fish 

 the eels have multiplied a thousand fold ; a cart 

 load may be had of them.
