salmon of the Sclioodic Lakes we find larger eggs than with the larger 

 migratory salmon (Salmo salar), although our ichthyologists maintain 

 that these two fish are identical." 



III. The land-locked salmon, which was introduced into Germany 

 about a year ago, is the third American salmonidse which we possess. 

 Last winter Professor Baird sent us 10,000 eggs of this fish. From all I 

 had heard about the land-locked salmon, I determined to choose deep 

 mountain lakes in Bavaria for this fish ; but I also sent 1,500 eggs each 

 to Freiburg and HiiningeD for experiments and observations. So far 

 only the healthy development of the young fry has been reported, and 

 farther results are still to be looked for. 



I meanwhile take the liberty to give the following report of Mr. At- 

 kins, relative to this fish, which, unfortunately, reached me later than 

 the above-mentioned eggs, and which suggests the propriety of scatter- 

 ing the eggs more in future. Mr. Atkins writes : 



"I am not able to give you the exact depth and area of the lakes 

 where the land-locked salmon is found ; but among them there are cer- 

 tainly lakes which have a depth of less than 100 feet and an area of 

 less than 1,000 acres. The largest lake in which this salmon is found, 

 and after which it is generally called, Lake Sebago, has an extent of 

 50 square miles. The lakes in which these salmon are found in large 

 number are surrounded by a flat country. Lake Sebago is situated in 

 a flat sandy country, and on the great lake in the Schoodic Hills there is 

 no hill higher than GOO feet over the surface of the lake. None of the 

 lakes in question is located in a mountainous region. 



" There are altogether only about twenty lakes, located in four not 

 very extensive river regions in Maine, where this salmon (which does 

 not migrate) is found. Relatively speaking it is, therefore, a rare fish, 

 for Maine has hundreds of lakes. 



"In the Schoodic Lakes this salmon reaches a weight of 5 pounds, and 

 in Lake Sebago 12 pounds. In exceptional cases it reaches a weight 

 of 10 pounds in the former lakes, and from 18 to 20 pounds in the lat- 

 ter. This fish is prized more highly in the United States than any 

 other kind of salmonida3. 



" These fish commence to spawn in October, and their principal 

 spawning-season is from November 1 to 20. Like Salmo fontinalis, they 

 spawn in running streams. In small artificial basins they do not grow 

 as rapidly as Salmo fontinalis. They are generally caught in May and 

 June, but also in July, September, and during the winter months. 



"The usual bait in May is the skin of salt pork; in June, artificial 

 flies ; and in winter, some small live fish." 



IV. For two winters large numbers (250,000 to 300,000) of eggs of the 

 white fish, Coregonus albtis, have been successfnlly shipped to Germany 

 from the United States ; and we, therefore, possess in this fish a fourth 

 salmonidfe.
