that any effort was made to stock streams other than 

 those in which the grayling was native. 



In 1909 the State Fish Commission of Montana ob- 

 tained a quantity of grayling eggs and planted over one 

 million fry in Georgetown Lake, which is located on the 

 headwaters of Flint Creek, which flows toward the 

 Pacific. 



For two years, nothing was known as to the result 

 of the planting, but at the end of this time fishermen 

 reported catching grayling in Georgetown Lake, but only 

 in small numbers. The third year many were caught, 

 some of them weighing two pounds and over, and at the 

 end of two years and a half reports were received that 

 grayling weighing in the neighborhood of five pounds 

 had been caught in this lake. As the fish rarely reaches 

 a weight of two pounds in its native habitat the large 

 size of those caught can only be accounted for on the 

 theory that the water temperature and food supply in 

 Georgetown Lake are both favorable to large growth. 

 The State Fish Commission has thus succeeded in plant- 

 ing the grayling in at least one stream which flows west- 

 ward to the Pacific and the success attained encourages 

 further efforts in this direction. 



That the fish have taken kindly to their new home is 

 shown by the fact that during the spawning season of 

 1913, they entered the two inlets to this lake in great 

 numbers to spawn. At one time there were held in the 

 traps set for catching them, over eleven thousand of 

 spawning age, from which were taken about fifteen mil- 

 lion eggs which were handled in the hatchery at Ana- 

 conda, but with only partial success. The fry, which 

 resulted from the eggs taken, were many of them planted 

 in other streams on the west side of the Rocky Mountains 

 and favorable results are hoped for. 



In 1910 there were planted in the Bitter Root River, 

 about fifty thousand grayling fry, and in 1911 and 1912 

 other plantings were made, but so far no results have 

 been noticed. While reports are at times received that
