346 FIFTEENTH ANNUAL REPORT OF THE 



direction of the Commissioner, who is unwilling to place bass in the Adiron- 

 dack region with the risk of its spread into trout waters. 



Brown Trout 



Early in November, 1909, the water was so low in the creek at the 

 Caledonia Station that it was very difficult to move the brown trout into 

 the ponds for stripping purposes. The water was also unusually warm so 

 that it was necessary to wait for a raise of water or for colder weather. 



On September 3, 1909, the brown trout at Caledonia were beginning 

 to make excavations in the pond bottom, as they always do about a month 

 or so before the spawning season begins. 



Mr. G. H. Vail, of Malone, on August 10, 1909, reported that this trout 

 was planted in Lake Titus, near Malone, about ten years ago. Recently 

 two of these fish were found dead, one weighing eight pounds and another 

 weighing eleven. Three or four years ago two other specimens were found 

 at the top of the water almost dead and were captured. Each of them 

 weighed a little over nine pounds, and both were apparently in good con- 

 dition. 



It has been found very difficult to capture this trout by angling. Occa- 

 sionally one is taken with a fly at night only. 



Rainbow Trout 



On March 17, 1909, the rainbow trout at the Pleasant Valley Station 

 which had been attacked with inflammation of the gills were improving 

 after treatment with salt. 



On September 8, 1909, the stock of fingerling rainbows at the Cale- 

 donia Station had been reduced to about 13,000. The trout spawned later 

 than usual in 1909 and the distribution, as the result, extended later. 



Mr. John N. Ross, secretary, Owasco Lake Anglers' Association, 

 Auburn, N.Y., under date of July 19, 1909, stated that some little rainbows 

 received a few days earlier were accustoming themselves to their new 

 surroundings and were feeding busily on insects at the surface of the water. 

 He believes that the smaller fish are more hardy than the larger ones, 

 which often die in great numbers if shipped in the warm months. 



Mr. Charles L. Paige, of Shasta, Cal., had brook trout and rainbow 

 trout in open outdoor pools and ponds. He finds that when the tempera-
