NATURALIZATION OF FISHES. 207 



stocking their trout pond. The following is from the same 

 letter : 



" Our b&3S-pond of sixty acres, and twenty feet deep in 

 some places, adjoins that intended to be occupied by the 

 trout, and is separated from it, by a small embankment 

 extending across a narrow neck of land, which, in low 

 water, is sometimes dry. Early in the spring of 1866, we 

 put into it twenty-nine large black bass, and as many more 

 during the summer, to make the number exceed one hun- 

 dred. We think those we put in early spawned the same 

 season, as a numerous progeny (about one and a half inches 

 long) were observed by the men who had charge of the 

 pond. The young bass are readily distinguished from the 

 perch, which had already occupied it. I can not say how 

 large the bass have grown by this time. We shall restrict 

 the fishing to the fly. As regards the perch, we have no 

 apprehension of the injury they may do the bass, but have 

 fears that those in the smaller pond will be destructive to 

 the young trout. We shall therefore try to seine out the 

 perch from the latter, during the coming summer. As we 

 do not contemplate feeding the young trout after we put 

 them in the pond, we will rear them in troughs until 

 autumn, by which time, we hope they will be large enough 

 to take care of themselves, and escape any perch that may 

 be left after dragging the pond with the seine." 



It will be seen by the foregoing, to what an extent the 



May each year, occasionally extend special invitations to brethren 

 of the angle. Wholesome regulations prevail, and good order 

 characterizes the assemblage of the members.
