SALMON INDUSTRY. 
The most prominent features of the salmon industry growing out 
of the operations of 1920 are (1) the continued falling off in the 
catch of salmon in southeast Alaska and (2) the increase in pro- 
duction in both central and western Alaska. But the catch of 
salmon in any district may not be a sufficient indicator of the condi- 
tion of the fisheries therein unless considered in connection with the 
character of fishing activities, the amount of gear used, length of 
season, and the intensiveness of operations. Nor can an accurate 
analysis of the condition of the fisheries be made until the position 
and influence of these factors are determined; and even then there 
are other factors of less prominence which may have an important 
bearing on the question, as, for instance, the application of restric- 
tive measures designed to afford more prcetection to the runs of 
salmon. 
Consideration of certain pack figures in the southeastern district 
for a number of years back may be of interest. From 1912 to and 
including 1920 the pack of canned salmon in southeast Alaska did 
not vary “markedly, except from 1916 to 1917 and from 1919 to 1920. 
The first of these movements was upward, with an increase of more 
than 1,000,000 cases in 1917; the second marked change occured in 
1920, when there was a decrease of almost 900,000 cases from the 
previous year. In the three seasons of 1917, 1918, and 1919 the 
production of salmon in southeast Alaska reached its peak. In 1920 
the production may be considered as normal, upon the basis of the 
general average pack for a series of years, and was not exceeded in 
the period from 1910 to 1916, inclusive, except in 1915. 
In central Alaska there was an increase in the pack of all species 
of salmon except chums, and the total catch of salmon in that dis-
