The eggs retained at the station, which began in January to hatch, 

 produced 200,000 fry. 



The distribution of yearlings was commenced January 23, 1892, and 

 completed April 12. The number shipped was 45,722, which were con- 

 signed to applicants in Wisconsin, Michigan, Iowa, Indiana, Ohio, 

 Kentucky, New York, Pennsylvania, and Vermont. 



BlacTc- spotted trout. — On February 5, 1892, 1,000 seven-months old 

 trout of this species were received at the station, having been brought 

 by Mr. H. D. Dean, superintendent of the Leadville Station. They were 

 immediately placed in tanks, and commenced feeding well. 



Whitefish. — Of the 370,000 eggs of the whitefish received from the 

 Alpena Station, 100,000 each were forwarded to Switzerland, France, 

 and the Indiana Fish Commission at Eichmond. 



A noticeable feature in the work of the station was the success which 

 attended the shipments of eggs. In no shipment, which was reported 

 upon, was the loss more than 5 per cent, and in many cases there was 

 none. 



The loss among the rearing fish during the season was very great, 

 especially among the brook trout, which were attacked by a fungus. 

 The cause of this was not definitely determined, but was probably due 

 to the scarcity of water occasioned by the continued drought and unpre- 

 cedentedly warm weather during the whole season. The folloAving 

 table exhibits the progress of trout fry produced from the eggs of the 

 fall of 1891 to July 1, 1892:
