PROGRESS IN BIOLOGICAL INQUIRIES, 1926 00 | 
tor for British Columbia of the Department of Fisheries of the 
Dominion of Canada. In view cf the recent development of a certain 
type of mechanical fishway, which has been advertised widely as 
having solved the problem of getting fish over high dams, the com- 
mittee presented the following resolution, which was adopted by the 
executive committee: 
Whereas constant and nation-wide prupaganda has been maintained in 
newspapers, engineering and technical magazines, ete., conveying the impres- 
sion, based on the partial success of the experimental fishway at the Baker 
River Dam, near Concrete, Wash., that a complete solution has been reached 
of the problem of safeguarding salmon runs jeopardized by the construction of 
dams; and 
Whereas.in the opinion of this federation no solution of this problem has yet 
been reached that can properly be considered as of general application; and 
Whereas in the opinion of this federation the problem connected with each 
dam is individual and distinet ; and 
Whereas much of the work at Baker River Dam has so far been experi- 
mental and results there are not yet conclusive: Therefore, be it 
Resolved, That the International Pacific Salmon Investigation Federation, at 
its meeting on December 2, 1926, strongly disapprove the propaganda mentioned 
as being unwarranted and misleading; and further be it 
Resolved, That a copy of this resolution be presented to. newspapers and 
periodicals and to such officials and others as may be interested. 
ALASKA SALMON 
The salmon investigations in Alaska have been continued under the 
direction of Dr. C. H. Gilbert, special assistant, and Dr. W. H. Rich, 
chief investigator of salmon fisheries. The tagging experiments in 
the channels of southeastern Alaska were continued, and a total of 
13,100 salmon, representing four distinct species, were tagged and 
liberated. The results have not yet been compiled, but a report by 
Doctor Rich, covering the results of the tagging done in this district 
in 1924 and 1925, was published during the past year as Document 
No. 1005. 
In addition to the tagging experiments conducted in the channels 
of southeastern Alaska, efforts were made, in cooperation with the 
fishery authorities of Canada, British Columbia, and the States of 
Washington, Oregon, and California, to tag fish caught in the ocean 
mainly by trolling. These fish are of two species—the chinook or 
king salmon and the silver salmon. Including the work done by all 
agencies, approximately 2,500 fish, were tagged along the coast. be- 
tween Monterey Bay and the outside coast of southeastern Alaska. 
While the data are not yet sufficiently complete to warrant final con- 
clusions, it appears quite certain that these fish range quite widely 
up and down the coast. The troll fishery for salmon thus assumes an 
interstate and international character, and this fact will have an 
important bearing on the nature of the methods adopted for the care 
of such of the salmon resources as are affected by trolling. 
The intensive study and analysis (by means of scale examinations) 
of the salmon runs in a large number of the more important salmon 
streams of Alaska has been continued by Doctor Gilbert. Counting 
wiers for the enumeration of the spawning escapements have been 
maintained, as for a number of years past, in the Karluk and 
Chignik Rivers, at two of the streams that enter Olga Bay, Kodiak 
Island, at Thin Point and Morzhovoi Bay, Alaska Peninsula, and in
