 1 Year Stream 



Taking first the Rivers inlet fish all of which were of the 1-year 

 stream type, the first year's growth varies mainly from 2-0 to 2-9. 

 This range corresponds to the range of the yearlings recorded by 

 Gilbert from this area. The average, 2-5 inches, is the same for the 

 4-year and the 5-year fish. The second year's growth varies from 5 • 1 

 to 8 • 6, and the third year's from 7 • 9 to 10-9. The fourth year growth 

 in the 5-year class varies from 2-8 to 6-4, with an average of 4 • 4. Al- 

 though the fourth year growth of the 4-year class is complete when it 

 comes into the inlet, the year is not a complete one and hence the 

 growth is not so great on the average as that of the fourth year of the 

 5-year class, the individuals of which complete their fourth year. The
