EXPERIMENTS IN STOCKING 241 



pounds was caught, whilst the nine fish killed 

 in that month weighed ten pounds six ounces. 



In February 1890 I added 100 two year old 

 Loch Lev ens. These increased to three-quarters 

 of a pound weight in 1891, and no more were 

 imported into this water after 1890, for the 

 trout have bred in it in spite of the absence 

 of any stream. This seems to me an interest- 

 ing fact, and it is one which, so far as this 

 water is concerned, is beyond all doubt. In 1892 

 trout of about four ounces appeared in it ; and 

 I have a note to the effect that in 1894, "there 

 are many fat and pretty half-pound trout, which 

 rise freely." Those small fish, it is clear, could 

 not be the two year old trout of 1890, for the 

 latter had grown into mature fish of larger size 

 in 1891 ; and if any doubt still remains it is 

 surely disposed of by the fact that a record has 

 been kept by me of the number of trout killed 

 out of this water, and now amounts to 321 trout 

 of three-quarters of a pound and upwards, against 

 a total of only 300 trout introduced. It must 

 be borne in mind also that my list of the trout 

 killed is probably not complete, for some others, 

 especially of the yearlings in 1887, must have
