EXPERIMENTS IN STOCKING 239 



September 1891. Out of the seventy-five fon- 

 tinalis put in only seven were killed altogether, 

 and the experiment has in consequence not been 

 repeated. 



In regard to trout, on the other hand, out of 

 about 250 (including the 200 yearlings intro- 

 duced in 1887) put in at various times up to 

 1892, nearly 100 have been killed with fly, 

 and though many have doubtless escaped during 

 floods, yet there still remain a few in the pond. 

 No small trout have appeared, and it is clear 

 that those which do remain are fish which have 

 been put into the pond artificially and not 

 reared in it naturally. The result altogether has 

 been an interesting illustration of the migratory 

 nature of fontinalis as compared with our own 

 trout, and it should be added that though one 

 or two of the fontinalis appeared for a year or 

 two in the burn below the pond, and found 

 their way into a larger burn well stocked with 

 trout, yet none of them remained there, and 

 they have, I t believe, entirely disappeared. 



My second experiment was tried in a different 

 place which was originally a quarry. It has 

 been disused for many years, and a natural
