BULLETIN OF THE UNITED STATES FISH COMMISSION. 367 



Disposal of fry. 



Brook trout, 10,000 sold to private parties ; 5,000 retained in ponds. 



The land-locked salmon eggs were forwarded from Maine to this 

 hatchery for reshipment to California, but on opening the crates the 

 eggs were found too far advanced for further shipment ; they were, 

 therefore, hatched and distributed to Iowa and Minnesota waters. 



Season of 1880-'81. 



Eggs of whitefish placed in hatching- jars, 13,780,000. 



Shipments of eggs were made as follows: To Germany, 250,000 ; Maine, 

 1,000,000; Iowa, 500,000; Minnesota, 250,000; Kentucky, 500,000; Cali- 

 fornia, 500,000; Nevada, 100,000; and Pennsylvania, 100,000; total, 

 3,200,000. With one exception, these shipments were made with per- 

 fect success. Something over nine million minnows were also hatched, 

 and released in the waters of the Great Lakes. 



Number of eggs of brook trout placed in hatching-boxes, 75,000, dis- 

 posed of as follows: 50,000 sold to private parties; loss on eggs, 12,000; 

 fish hatched, 13,000, of which 3,000 were retained in artificial ponds and 

 the remainder planted in adjacent streams. 



A few hundred eggs of California trout were also obtained from a 

 few adult fish of this species held in the ponds of the station. These 

 were hatched, and the fry retained at the hatchery. 



Season of 1881-'82. 



The work was quite largely increased this season. The number of 

 whitefish embryos placed in the hatching-jars from fisheries of Lake 

 Erie and Lake Huron was something over 22,000,000. From these 

 nearly 2,000,000 were shipped, and over 17,000,000 fish hatched and 

 planted. The minnows were distributed by the United States Fish Com- 

 mission car to various points on the Great Lakes, and eggs were shipped 

 as follows: To Germany, 300,000; France, 250,000; Iowa, 500,000 ; Con- 

 necticut, 10,000 ; California, 750,000, and New Jersey, 100,000. 



About 60,000 eggs of lake trout were obtained from Lake Huron fish- 

 eries and brought to this hatchery for incubation and shipping. Of 

 these, 20,000 were shipped to F. Mather, Newark, N. J., for transmis- 

 sion to Germany, and 30,000 were sent to the State of Iowa. 



From the California trout mentioned above, some 4,000 or 5,000 eggs 

 were obtained ; they were hatched and the fry retained at the hatchery. 



Upwards of 150,000 eggs of brook trout were laid in from the breed- 

 ing-fish reared in the artificial ponds adjoining the hatchery; 30,000 of 

 these were shipped to the Druid Hill hatchery, Baltimore, Md., and 

 20,000 to F. Mather, Newark, N. J., for reshipment to France. About 

 75 per cent, of the remainder were hatched; 30,000 of these were taken 

 to West Virginia by United States Fish Commission car No. 1 ; 10,000
