264 AMERICAN FISH CULTURE. 



VII. 



COLD SPRING TROUT-PONDS. 



The following account of these ponds, and matters con- 

 nected with them, has been written out by the proprietor. 

 Rev. Livingston Stone, at my own request, for this book. 

 It was not until I had completed the chapters on trout- 

 breeding, that I received any communication from Mr. 

 Stone. Having occasion to write him in regard to the 

 salmon ova placed under his charge by the New Hampshire 

 Fish Commission, I found from his letters in reply, that 

 his establishment was more extensive, and embraced the 

 cultivation of a greater variety, than I had supposed. It 

 will be seen that he fully endorses in its many bearings, all 

 that I have said as to the importance of fish culture. His 

 remarks on the necessity, when one rears them in large 

 numbers, of having young trout in a defined space where 

 they can be fed and attended to, in substance, correspond 

 with the directions I have given. Though neither of us 

 was aware of the other having engaged in this line of 

 business, we have from similar experience and experiments, 

 arrived at the same conclusions on the most important 

 points connected with it. Mr. Stone's rearing-box, a model 

 of which he sent me a few weeks since, is the most complete 

 contrivance of the kind I have seen, and is particularly 

 adapted to the wants of those who wish to raise a few 

 thousand young trout. With the accompanying directions, 

 the proper requisites, and with ordinary care, one can 

 scarcely go wrong.
