SALMON FISHERIES OF ALASKA. 



contracts within its shallow narrow limits and flows over a long series of rapids. The 

 tide rises in the river from 3 to 5 feet, and its influence is felt throughout the lagoon. 

 The fresh water begins practically at the rapids, about 2J miles from the bay. During 

 the time of our stay the water was so clear that salmon and trout could be seen on the 

 bottom. During freshets, of course, large quantities of soil are brought down, making 

 the water turbid, and numerous plants are rooted up and floated to sea by the current. 

 The temperature of the water at Karluk and other localities, as recorded by Mr. Stone, 

 varied as follows:
