The Grayling 



tic grayling is regarded as the parent stock, Distribution 

 while the others are possibly relics of the 

 glacial period. This seems probable in con- 

 nection with the fact that in the mountains 

 where the sources of the Jefferson River 

 arise, there is a deep lake, some four miles 

 long (Elk Lake), that in addition to gray- 

 ling is inhabited by the Great Lake, or 

 Mackinaw, trout. This trout is found no- 

 where else west of the Great Lakes except 

 in Canada. 



Beginning with 1874 numerous attempts Propagation of 

 were made to propagate the Michigan gray- the ( 

 ling artificially, but after repeated failures 

 all effort in this direction was abandoned. 

 When a station of the U. S. Fish Commis- 

 sion was established at Bozeman, Mon- 

 tana, in 1897, the Commission, under my 

 supervision, began a series of experiments in 

 grayling culture, resulting in complete suc- 

 cess, so that for several years millions of 

 grayling have been hatched and planted, 

 and millions of eggs have been shipped to 

 other stations of the Bureau, where they 

 have been hatched and planted in Eastern
