The second summary of drum collections, from May 9 to June 5, 1926, brought the 

 O or youngest year class into consideration, with the fish ranging in length from 1 to 

 15 centimeters (0.4 to 5.9 inches). Several sharp modes exist within the length dis- 

 tribution of this O class, owing possibly to the various difl'erences in time of hatching. 

 The collections from June 6 to July 9, 1926, however, smoothed out this irregular 

 distribution. 



The O year class, positively known to be in its first year, grew rapidly during the 

 summer of 1926, and by November (October 10 to November 5) had attained a 

 modal length of 21 centimeters (8.2 inches), compared with the modal length at 11 

 centimeters (4.3 inches) shown by the class during June. Collections became much 

 smaller during the winter, but spring catches (April 3 to May 22) showed that the 

 class (I) had attained a modal length of about 26 centimeters (10.2 inches) when a
