76 EEPOET OF THE SECRETARY. 



keep the fish in their pens, and prevented any measure of success. It 

 is hoped that during normal seasons the j)ropagation of the cod may be 

 considered as a perfectly feasible undertaking, and one promising im- 

 j)ortant economical results. 



The operations of the Commission in connection with the hatching of 

 shad have also been of increasing importance during the year. The 

 work was commenced in Albemarle Sound, North Carolina, and many 

 millions' of fish were hatched out. A station was then established on 

 the Potomac Eiver. By the courtesy of the authorities ,of the Navy 

 Department, and especially of the Chief of the Bureau of Yards and 

 Docks, a hatching station was extemporized for hatching out the eggs 

 of tlie shad obtained by the steamer Jjookout from the seines and gilling 

 stations down the Potomac, especially in the vicinity of Fort Washington. 



Another station was made at Havre de Grace, Maryland, and at the 

 two places about 30,000,000 shad were successfully hatched out. A 

 large i)roportion of these were necessarily j^laced in the rivers whence 

 the eggs were obtained. IMany millious, however, were distributed by 

 the messengers of the Commission to various localities throughout the 

 United States, especially to the waters of the Mississippi Valley. 



The ^propagation of the Salmonidcc has also been conducted with sat- 

 isfactory results. The McCloud Eiver station, for the cultivation of the 

 California orQuinnat salmon, was in successful operation, and furnished 

 many millions of eggs, which were distributed, as usual, to all parts of 

 the United States. Some of these eggs went to Germany, France, and 

 Holland, where they arrived in good condition, and were hatched out 

 very satisfactorily. 



After an interval of several years, work was resumed at the station 

 on the Penobscot Eiver for obtaining the eggs of the Penobscot salmon, 

 and a distribution of these fish was made to the principal rivers of the 

 Northern and Eastern States. 



An unusually largo gathering of eggs of the land-locked salmon was 

 made at the station on Grand Lake Stream, this fish i^romising to be of 

 great value in the cold, deep lakes of the country. 



Work on a large scale in connection with the white-fish of the great 

 lakes was commenced this year by establishing a station at Northvilk, 

 Michigan, under the charge of Mr. Frank N. Clark. With the neces- 

 sary number of assistants, Superintendent Clark obtained a bountiful 

 supply of eggs in the adjacent lakes, and gathered into the hatching- 

 house about 13,000,000. Some of these were distributed to different 

 parts of the country; but by far the greater part were hatched out and 

 placed i)artly in Lake Michigan, ijartly in Lake Huron, and partly in 

 Detroit Eiver. 



An interesting experiment was made in the artificial propagation of 

 the striped bass or rock-fish of the Southern States — the eggs from a 

 gravid female having been properly impregnated, a large number of
