twenty-nine subspecies. Of these three groups, the first is 

 celebrated for the beauty of form, picturesque surroundings, 

 and gamy quaUties of its members. The sahiion and white- 

 fish are noted chiefly for their great vahie as food. 



Few persons, it is safe to say, know either the size or the 

 subdivisions of the group of American trout and charrs. 

 The species are numerous, beautiful and widely distributed 

 north of a line drawn from New York City to San Diego, 

 California. For a clear and correct understanding of these 

 fishes, a diagram is absolutely necessary. The world is in- 

 debted to Dr. D. S. Jordan for the researches which have 

 made him the leading authority on this large and extremely 

 interesting group of fishes, and by means of which it has been 

 made comprehensible. 



Of North American trout, generally, the centre of abun- 

 dance is certainly west of the Rocky Mountains, and the 

 group as a whole is decidedly of the Far West. The trout of 

 the eastern United States are but the advance guard of the 

 main body which fills the swirling mountain streams and lakes 

 of the Rocky Mountain region and the Pacific coast. Our 

 famous and well-beloved speckled trout of the East is but a 

 trifling incident in comparison with the many fine species 

 found in the true home of the Trout Famil}^ 



Dr. Jordan believes that our original stock of trout came 

 to us from Asia, and "extended its range southward to the 

 upper Columbia, thence over the continental divide via Two- 

 Ocean Pass to the Yellowstone and the Missouri Rivers, the
