TROUT. 



In June last, the commissioners visited the trout breeding 

 establishment of Messrs. Dexter & Cooledge, at West Barn-

 of Mr. Holmes, a practical pisaculturalist, to oversee the

 perfect arrangements for obtaining our own spawn. 



In distributing these trout, the commissioners will be 

 careful to select those streams freest from saw mills, tan- 

 neries, &c., which tend to destroy the fish. A portion will
