trout which had ascended the stream for the purpose 

 of spawning. These were the result of fry liberated in 

 this lake some years before. 



"In addition to the information given you, by ref- 

 erence to the Commissioner's report for 1896, pages 

 136 to 139, you will find some data on this subject, col- 

 lated by Dr. Smith. I am also under the impression, 

 without being able to give you the exact figures, that 

 the rivers and streams in the State of Wisconsin have 

 been very thoroughly stocked." 



Other letters of like tenor were received from Mr. 

 John G. Roberts, Superintendent of the New York 

 State hatchery at Saranac Inn, in the Adirondacks; 

 Mr. W. F. Page, Mr. W. E. Meehan, Assistant Secre- 

 tary and Statistician of Pennsylvania Fish Commis- 

 sion, and others; but enough has been cited to show

LAKE TROUT {SalveltHus nomaycush) . 



This species is gray-spotted, the spots sometimes 

 tinged with red. Its caudal fin is deeply forked. They 

 require colder water than the brook trout, and in the 

 summer they are only found in the deeper waters of 

 those lakes which have a depth of forty or more feet, 

 and have large springs at the bottom. The lake trout 

 is not much of a favorite with anglers because it must 

 be fished for in such deep water, and its fighting quali- 

 ties are inferior to those of the brook trout. 



The "salmon" of the Adirondacks, which one hears 

 of so much, is simply the lake trout, sometimes called 

 salmon-trout, and often the first part of the name only 

 is used. But they are not salmon nor salmon-trout.
