Omitted because of closed period. > 1920 and 1930 omitted. 
The curves for even years are presented in the lower section of the figure, and 
those for odd years in the upper section. The curves for kings were omitted, since 
the highest point in any one week in even years was less than 0.4 percent, and in odd 
years was less than 0.1 percent. The scale for odd years was increased so that the 
proportion of the run afforded by all species other than pinks should be equal in odd- 
and even-numbered years. Because of the extreme peak the odd-year curve was 
truncated, hence the percentage occurrence of the total catch and the proportion 
represented by pink salmon are not shown for the weeks from August 18 to September 
8. These curves vary most from those of fishing effort in the more extreme differ- 
ences between the summer and fall fisheries. It is evident that the number of fish 
per delivery is much greater during the height of the run of pink salmon in odd years 
and during that of chum salmon in even years.
