It is found generally in British America and Alaska, abundant north-

THE TRirol.iil; (.RAYLING. 



Thymallus tricolor occurs in the streams of the southern peninsula of 

 Michigan, and is abundant in Ausable River, and in the headwaters of the 

 Missouri in Montana. 



It was described by Cope in 1865, but his notice, having been published 

 in the proceedings of a scientific society not generally read by sportsmen,, 

 attracted but little attention. Popular interest was first excited in 1873, 

 by the discussions in " Forest and Stream," and by a letter from Professor 

 Agassiz, published extensively in the daily papers, acknowledging the 

 receipt of two specimens sent to him from New York through the agency 

 of Mr. Hallock, who had received them from Michigan. The subject 

 was then taken up by the newspapers, and the Grayling was soon well 

 known. A name closely associated with the study of the Grayling is the 

 honored one of the late James W. Milner. In 1S71, iNIr. Milner, in 

 company with Mr. I). H. Fitzhugh, of Bay City, Mich., visited the 

 Jordan River for the purpose of procuring specimens of this fish; but, 

 although many were seen in the clear cold waters, they could not be in- 

 duced to take the hook during the day spent on the river. In 1873 he 

 again visited this region, and subsequently published several popular 

 articles on the subject of " Graylings of North America," which consti- 

 tute a considerable portion of the very few essays finished by him, out of 

 the many which were planned, and interrupted by his untimely death. 



Milner's description of the habitat of the Grayling is excellent: 

 '•In the center of tlie Lower Peninsula of Michigan is an elevated plateau, 

 a sandy region, with a soil containing a \ery small percent, of organic
