until the sack is absorbed a sufficient number of trout, ami 

 turn them into the stream. This can either be clone by the 

 State from its central hatching house, or by individuals living 

 on such streams. 

 The Brook Trout — West of Eocky Mountains — (.Salmo ridea.} 



We received a few eggs of this variety of the Brook Trout, 

 which differs from our "Salmo fontinalis," in that it is 

 marked with black spots instead of red. This fish is describ- 

 ed as being of delicious flavor, it rises boldly to the fly, take& 

 it greedily, is active, plump, and affords geod sport to the 

 angler. The eggs were received from California by Professer 

 Baird, through the mail, and remailed to Mr.. Ferguson in 

 Baltimore. They were successfully hatched in his library, 

 and have ])een placed in a pond in Druid Hill Park, which 

 had been prepared by the Park Commissioners, for fish 

 culture, near the "Crow's Nest." Many of them were wash- 

 ed away by severe rains before the completion of the ponds. 

 The remaining fish are doing well and growing finely, per- 

 haps more rapidh^ than their cousins of the Atlantic slope. 

 Salmox — (Salmo salar.) 



Prof. Baird having jn-esented the State with eighty thou- 

 sand salmon eggs, from the Bucksjiort breeding establish- 

 ment, which is operated by the U. S. Commissioner, and the 

 Commissioners of the New England States, and superintend- 

 ed by Mr. Charles G. Atkins, we placed them under Mr. 

 Kent's care, at his hatching house at "Green Spring," and 

 when readj^for distribution, disposed of them as appears in 

 the table. Wo are not hopeful of any results, as this variety 

 is an inhabitant of much colder waters. Those which we 

 have kept over, have not thrived as the Western variety have. 



The Salmon or Lake Trout — {Salmo namaycusli.) 

 We obtained a few thousand eggs of the Salmon Trout 

 from the State of New York, some of which were hatched at 

 the mansion in Druid Hill Park, by permission of the Park 

 Commission, but unfortunately, during the severe cold in- 

 February, the pipe which furnished the jars with Avater froze,. 

 and the fish and eggs were all lost. Some two thousand 

 were successfully hatched in the library of one of your Com- 

 missioners in Baltimore, and about one thousand. of the young
