TROUT BREEDING. 101 



is in these details, which are so necessary to success, that 

 most of the essays on trout culture are deficient. As I 

 have already remarked, it is an industry which is yet in its 

 infancy, and although I have given all the directions which 

 have arisen from Mr. Ainsworth's and my own experience, 

 and much that I have learned of Seth Green, there will 

 still be additional discoveries in the minutiae of the art, as 

 progress is made in it. 



I deem it a branch of industry that should claim the 

 attention of our national government. If the agricultural 

 bureau has no discretionary power to foster it, special legis- 

 lation should be directed to it, and appropriations made for 

 the purpose of experiments, and its promotion.
