In Table 13 we give the percentages of each age group in the series of random 

 samplings throughout the season. The results are very similar to those we obtained 

 in the run of 1922. Certain groups are most abundantly represented in the early 

 part of the run or are entirely confined to it, while other groups are the reverse of this 

 and either grow more numerous in the latter part of the run or else are found in this 

 part only. In our discussion of the run of 1922, we stated that the data we had for 

 that year indicated that the early running groups had spent the longest time in the 

 sea before maturing, while the groups that showed a distinct tendency to mature 

 and enter the run in the latter part of the season were those whose sojourn in the sea 

 had been of shorter duration. We will now pass the different groups of the 1924 run 

 in review to ascertain what degree of correspondence is found in the two years. 



The two groups that spent the least time in the sea are the 3 3 and the 4 4 groups. 

 Each of these matured and entered the run during the same season in which it 

 descended to the sea as a fingerhng. As shown in Table 13, the few individuals of
