Hon. J. S. Whipple, Forest, Fish and Game Commissioner: 



SIR. — The report herewith submitted relates chiefly to the practical 

 work of the hatcheries. It includes accounts of repairs and improve- 

 ments at all the fish cultural stations, supplemented by the statements 

 of the foremen, remarks on the distribution of young fish, notes on many 

 of the species of fish reared or met with in fish cultural operations, food 

 of trout, growth of brook trout, diseases affecting the life and vitality of 

 the fish, treatment of these various disorders, and courtesies received from 

 many sources or extended to correspondents and collaborators. These 

 subjects are so arranged as to facilitate reference by persons interested in 

 the progress of the work. 



The output of the hatcheries was greatly increased over the yield of 

 former years and everything points to still further gains. In whitefish 

 culture much difficulty was found in collecting a sufficient number of eggs, 

 notwithstanding the active and long-continued planting of fry. The causes 

 of this falling off are not known, but will be carefully investigated. 



General conditions are more favorable than ever before, and the out- 

 look for the future is bright.
