SALMON AND SALMON FISHERIES OF SWIFTSURE BANK 
735 
The increase in larger vessels in 1912, which resulted from the development of the 
cape fishery, is very apparent. These larger craft had been underpowered and not 
particularly successful, and smaller vessels were more popular during the next few 
years. The two large vessels, built in 1909 and 1911, were not built as purse seiners 
but were converted in later years. 
The second abrupt size increase, beginning in 1916, was terminated by the depres- 
sion in 1921. Building was resumed in 1924, but construction never reached the pro- 
portions of earlier years, for the declining abundance of salmon discouraged sustained 
building. It was at this time, however, that Diesel-engined vessels began to appear in 
the fleet. The depression following 1929 sharply curtailed the number of vessels under 
construction, and a recession in size similar to that in the years following 1921 is 
evident.
