SOME PRELIMINARY OBSERVATIONS CONCERNING THE 

 ARTIFICIAL CULTURE OF THE GRAYLING. 



The grayling of Montana exists only in the tributaries of the 

 Missoin-i River, above the falls, but principally in the three forks 

 of that river, the JetTerson, Madison and Gallatin Rivers, and their 

 tributaries. 



In 1805 Lewis and Clark found the grayling near the head- 

 waters of the JefTerson. and in the history of their wonderful ex- 

 pedition spoke of it as follows: "Toward evening we formed a 

 drag of bushes, and in about two hours caught 528 good fish, 

 most of them large trout. Among them we observed for the first 

 time ten or twelve trout of a white or silvery color, except on 

 the back and head, where they are of a bluish cast; in appearance 

 and shape they resemble exactly the speckled trout, except that 

 thev are not so large, though the scales are 'much larger: the 

 flavor is equally good." 



This fish was not subse(|uently identified from this descrip- 

 tion, though any one acquainted with the locality and the fishes of 

 the headwaters of the jefTferson could not doubt for a moment 

 that the grayling was meant. Dr. Elliott Coues in his edition of 

 the History of the Lewis and Clark Expedition, thinks the de- 

 scription applies to the blue-backed salmon (O. nerka) of the 

 Pacific coast, though he says this genus is not -known to exist 

 in Atlantic waters. 



In a recent conmnmication to "Forest and Stream" I have ad- 

 vised the adoption of the name Thymallus lewisi for the grayling, 

 on the strength of Lewis' description, and to relegate to synonomy 

 Cuvicr's name of Thymallus ontariensis. based on a specimen, the 

 locality of which is unknown, though it was wrongly attributed, 

 as I believe, to Lake Ontario. 



Seth Green and Fred Mather claim to have hatched the gray- 

 ling artificially from eggs procured in Michigan in 1874. Seth 

 Green has a brief notice in his "Fish Ilatching and Fish Catch-
