30 U. S. BUREAU OF FISHERIES. 
Tn the last analysis, the suppression of this business appears to be 
almost wholly in the hands of the cannerymen and the operators of 
traps themselves. It seems reasonable to conclude that refusal to 
purchase salmon from suspicious sources and the employment of 
honest watchmen will make it unprofitable and cause the entire cessa- 
tion of the reprehensible practice. 
TERRITORIAL FISH COMMISSION. 
The Alaska Territorial Fish Commission was created by the legis- 
lature at its session early in 1919, and‘at the same time the sum of 
$80,000 was appropriated for its work during the ensuing biennium. 
The efforts of the commission have been devoted chiefly to fish- 
cultural work, the removal of natural barriers in salmon streams, and 
the destruction of predatory trout. The commission has issued two 
printed reports covering its activities during each of the two years 
ending March 31. According to the report for the biennium ending 
March 31,1921, there was expended in the first year $27,901.24, and in 
the second year $40,143.66, thus leaving an unexpended balance of 
$11,955.10. Of the $27,901.24 expended in the first year, $12,072.08 
was spent for fish-cultural work, $6,373.98 for stream improvement, 
and the balance for general expenses, permanent improvements, etc. 
Of the $40,143.66 spent in the second half of the biennium, $16,573.71 
was chargeable fo propagation and $19,695.90 to stream improve- 
ment and the destruction of predatory fish, the balance going for 
general expenses. 
According to the reports of the commission, stream improvement 
work in 1919 was accomplished as follows: Juneau district, seven 
streams; Ketchikan district, eight; Cordova district, three; and 
Seward district, three. In 1920 this work was upon a more extensive 
scale, being reported as follows: Juneau district, seven streams; 
Ketchikan district, various streams south of Wrangell Narrows, num- 
ber not stated; Cordova district, five; and Seward district, eight. It 
is reported also that in the Juneau district 10,000 predatory fish 
were destroyed, and in the Cordova district 13,648 were destroyed. 
Mention is made also of the destruction of a considerable number 
of predatory fish in the Bristol Bay district. Figures in respect 
to this, however, are covered by the report by Dennis Winn, field 
superintendent of fish-cultural work for the Bureau, appearing on 
page 31. The Territory contributed $2,000 toward the fund for 
conducting this work in Bristol Bay. 
Details as to the fish-cultural and hatchery work of the commission 
will be found in the section of this report devoted to hatcheries. 
TERRITORIAL LICENSE TAX. 
Under the laws of Alaska a tax is levied on certain fishery prod- 
ucts and apparatus, and it is payable annually to the treasurer of 
Alaska. On May 11, 1921, the treasurer furnished a statement show- 
ing the collections as made to that date for the fiscal year ending 
December 31, 1920. As compared with collections for 1919, the reve- 
nues of the Territory fell off $51,901.14, which amount is almost 
covered, however, by delinquent taxes for 1920,
