Mil. J. A. MILNE ON THE 



its sjDawning ground a month later. But compare tkese scales 

 with text-fig. 115. This fish was forwarded to me from Toronto 

 on October 17th, so that it must have been procured at Lake 

 Shuswap some days earlier. 



Text-fia-. 115. 



;~A. 





Scale of Cohoe (O. hisutcli). $ . 3^ lbs. Shuswap Lake. 

 Weighed after spawning. 



According to Dr. Greene (Migration of Salmon in Columbia 

 B-iver, Bulletin of U.S. Bureau of Fisheries, vol. xxix. 1909), a 

 Silver Salmon travels about 7 miles per diem. This fish, then, 

 to reach Shuswap by, say, October 12th, must have ceased feeding 

 in the sea not later than 23rd August. It will be noticed that 

 the outer lines of the scale are still widely spaced, showing that 

 summer feeding aiid growth were still in progress up to the time 

 at which the fish left the sea for the river. 



The Humpback Salmon {Oncorliyncli%is gorhuscha). 



I have biit little to say at present about the Humpback, the 

 Dog Salmon, and the Steelhead Trout. 



The Humpback has flesh of a pale pink colour. It was not 

 used for canning purposes until quite lately, but now there is 

 a good trade in it with China and Japan, where it is much 

 esteemed. The Chinese, not being accustomed to red-fleshed 

 fish, were very shy of the canned Quinnats and Sockeyes when I 

 was in China in 1893, and this may account for their partiality 

 to the Humpback. 



The total weight of Humpbacks canned on the Pacific Coast in 

 1909 was 100,32(5,144 lbs., and over another 3,000,000 lbs. weight 

 was used in other ways.
