were not enough of them to make satisfactory bases for conclusions 

 and they may or may not be representative, hence, too much weight 

 must not be put on the conclusions that appear to be warranted. It 

 is interesting to examine them nevertheless. 



It will be noticed, in the first place, that there were no 4-year 

 fish of this type. There may have been some of them in the run, but 

 like the 3-year fish of the previous type, they may have been small 

 enough to pass through the net. There were 5-year fish and 6-year 

 fish, but the latter were very few in number (only 3). The disparity 

 agrees very well with that between the 5-year and 4-year fish in the 

 1-year stream type. There were not enough specimens to make it 

 worth while attempting an extended analysis of the growth or to make 

 a frequency curve, but it may be noted that taking the average, the 

 first year growth was 2-6 inches, the second 3-2, the third 8-2, the 

 fourth 6-1, the fifth in the 5 year class 2-4, in the 6-year class 3-3 

 and the sixth year in the 6-year class 1 • 4. 



It is profitable to compare this growth with that of the 1-year 

 stream type in the same river. The first year growth is much less, 

 almost as low as in the Rivers inlet fish. The second year growth is 

 much similar to that of the first year and in the different years in the 

 sea the two types correspond, but that of the 2-year stream is slightly 

 less in each case, so that by the time the third year in the sea is reached, 

 the 2-year stream fish has lost the excess length that it obtained by 

 remaining a year longer in fresh water, and the two are now prac- 

 tically the same length. The 5-year fish of the 2-year stream type, 

 having spent three summers and two winters in the sea, has a length of 

 22-5 inches as compared with 22-3 inches, the length of the 4-year 

 fish of the 1-year stream type that has spent the same length of time 

 in the sea. The 6-year fish, having" spent four summers and three 

 winters in the sea is 24-7 inches long, while the 5-year fish, the same 

 length of time in the sea, is 24 inches. It would seem, therefore, that 

 those sockeye that remain in the fresh water for the extra year, 

 practically lose that year as far as growth in length is concerned. 



The sockeye of the sea type remain to be considered. Here again 

 the numbers are not sufficiently great to provide satisfactory bases 

 for conclusions. Here the 3-year fish were big enough to be caught in 

 the net, but there were not many of them. The majority were 4-year 

 fish and there were some in the 5th year. If there were any 2-year 

 fish they were probably too small to be caught in the nets. 



The first year growth averages 6-4 inches, the second 8-3, the 

 third 6-5, with the portion of the third year in the 3-year class not
