220 THE ANGLEE-NATUEALIST. 



It is to be regretted, in the interest of science, that 

 the traveller was not allowed to continue his progress, so 

 that we might have had a fact instead of an hypothesis to 

 add to our knowledge of the subject. There seems to be 

 no doubt, however, that if a Pike is placed near the bank 

 of a river or lake where it has no means of seeing the 

 water, it will, by instinct, immediately begin to jump in the 

 proper direction. 



A somewhat analogous case to the above was com- 

 municated to me by a gentleman who happened to be 

 present on the occasion. Mr. Newenham, an English re- 

 sident at Antwerp, in order to test the migratory theory, 

 caused two contiguous ponds to be excavated, 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. 1 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 con- 

 clusion, once came under my own observation. A pool 5 or 

 6 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. 



Perhaps, however, the most remarkable occurrence of 

 this description is one which recently happened in the
