FISHES OF THE^ WEST. 337 



I'inally brought on board, exhausted, he is easily removed from 

 the hook." 



They are free, strong biters, and cannot be considered very 

 shy, as they will rise repeatedly to a fly if a failure is made in hook- 

 ing them. Often two, and occasionally three, are landed at once. 

 Nevertheless, experience proves that it sometimes requires all the 

 ingenuity of an experienced fly-fisherman to induce an occasional 

 rise, even when grayling are seen to be plentiful in the river. 

 Very many styles of flies are used. The favorite grayling fly is 

 made with a stone wing and yellow body ; brown and grey hackles, 

 the white and lead wing coachman, the silver widow, the Jewel fly, 

 and the professor, with light yellow dyed hackle, mostly used. In 

 fact any fly tied on No. 6 and 8 O'Shaughnessy hooks will kill, if 

 not too gaudy. 



The history of the discovery of the species is as follows : It 

 has been known for years to the people in adjacent counties, and 

 among the lumbermen, and generally called trout, distinguishing 

 it from the ordinary species by applying the local name of the 

 stream, as the " Hersey trout," or the "Jordan," or "Ausable" 

 trout. 



In the winter of 1864 and 1865, Prof. Edward D. Cope, of the 

 Philadelphia Academy of Sciences, worked up a large collection of 

 fishes, sent by Mr. M. Miles, of Lansing, belonging to educational 

 institutions of the State of Michigan. Among these he found this 

 species, readily detecting its relation to the genus Thymallus, and 

 giving it the name o{ tricolor. In the winter of 1872, Mr. D. Fitz- 

 hugh procured specimens and forwarded them to Professor Baird 

 of the Smithsonian Institution, and to Professor Agassiz, as well as 

 to prominent authorities of the hook and line profession. These 

 were the first specimens obtained by the museums, and were 

 regarded with a great deal of interest. Two obtained for the U. 

 S. Commission of Fisheries in 1871, from the Jordan River, were 

 lost in the great fire at Chicago. Mr. Fitzhugh subsequently 

 went before the legislature of his State and induced the passage of 

 a law protecting the grayling from a too rapid destruction. He 

 was also the first to communicate with reference to their habits 

 and qualities £K a game fish.
