The Northville and Alpena stations. — Mr. Frank K. Clark, in charge 

 of the Northville and Alpena (Mich.) stations, in the appendix to this 

 volume, makes an interesting report of the labor carried on by him 

 during 1882. The work performed in his department shows double the 

 results obtained heretofore in a single year. The new station at Alpena 

 was fitted up expressly' for the hatching of whitefish, and about 

 32,000,000 of these fish were planted from that station in the Great Lakes. 

 At the Northville station about 30,000,000 eggs of whitefish were re- 

 ceived. Of tliis number 12,000,000 eggs were shipped to various points 

 in the country, and 16,000,000 were hatched and deposited in the Great 

 Lakes. There were handled at this station also 277,000 lake trout, 

 473,000 brook trout, 7,000 rainbow trout, 1,400 " German" trout, and 

 20,000 hmd-locked salmoTij and 1,500 carp were distributed, in lots of 20, 

 to applicants in the Northwestern States. The station has been increased 

 in efficiency by the addition of two new ponds for breeding purposes. 

 Tlie Alpena liatchery, which has just been completed, is believed to be a 

 model establishment. It contains, besides a hatching room, an office and 

 dormitory and a storage room. The liatchery proper, which has a capa- 

 city for treating 100,000,000 eggs, is equipped especially for whitefish.
