 curious circumstances, which have come to my 

 knowledge, would appear to lend some colour to 

 the supposition. 



In order to test the migratory theory, Mr. 

 Newenham, an English resident at Antwerp, had 

 two small ponds excavated near together, and 

 stocked one with Pike, and the other with small 

 Roach, Dace, &c. At the end of the second day he 

 caused both ponds to be emptied, when it was found 

 that several of the Pike from pond No. i had made 

 their way by some means into pond No. 2, and 

 had destroyed a great part of the fry. 



A singular fact, pointing indirectly to the same 

 conclusion, once came under my own observation. 

 A pool five or six yards square, for the reception 

 of small fish, had been constructed close to a stew- 

 pond containing Pike ; the work had been finished 

 in the afternoon, and the pond left to fill. On 

 visiting it the next morning, I was surprised to find 

 it already occupied by a Jack of about | Ib. weight, 

 which had contrived thus early to take possession. 



The sudden appearance of Pike at certain times 

 is not less remarkable than their unaccountable 

 disappearance at others. There is no doubt that 

 in seasons of great heat or unusual drought, when 

 ponds or reservoirs have become rapidly dried up, 

 the Pike that were in them have vanished in a 

 very extraordinary manner, and that upon the 

 return of the water they have been immediately
