110 U. S. BUREAU OF FISHERIES, 
Section 10. 
(a) No purse seine shall be cast or placed in the water for fishing purposes within 
twenty-four hundred feet of anv trap net. 
(b) The use of purse selues for the capture of sockeye salmon shall be confined to 
the treaty waters southward and westward of a straight lime drawn from the ighthouse 
on Trial Island, British Columbia, to the northwest point of Whidbey Island, State of 
Washington. 
Section 1]. 
A salmon drift net shall not exceed nine hundred linear feet in length, and the 
vertical breadth thereof shall not exceed sixty meshes, and the sie of the mesh shall 
not be less than five and three-fourths inches, extension measure, when in ‘se. 
Had such a treaty been adopted and rigidly enforced 10 or 12 
years ago, it might have had a beneficial effect on the Fraser River- 
Puget Sound sockeye run, but the destruction of the run has pro- 
gressed to such an alarming extent during the past 7 years that only 
a total cessation of all fishing for sockeyes in this section for a 
term of years could have the slightest beneficial effect. The pro- 
posed regulations provide that ‘‘during the years 1920 to 1927, 
both years inclusive, no one shall fish for, catch, or kill any salmon 
from the 20th day of July to the 31st day of July in each year, both 
days inclusive; and during this close time no nets or appliances 
of any kind that will capture salmon may be used in these treaty 
waters * * *,.” This closed period runs concurrently on both 
sides of the line, and while it would have but a very slight effect if 
the salmon were able to reach the spawning grounds in this short 
period, it certainly can have none if the Canadian gill netters are 
enabled to start fishing just about the time the salmon have reached 
the mouth of the Fraser. 
The only hope of rehabilitating the sockeye run—and some well- 
informed observers have grave doubts whether anything will ever 
accomplish this desirable result—is to close the waters of Puget 
Sound through which the sockeyes pass and the Fraser River during 
the months of July and August or such other period as may be neces- 
sary to protect the sockeyes from the time they appear off the capes 
until they have passed beyond the fishermen on the Fraser River to 
all salmon fishing for a period of 8 or 12 years. As the sockeyes 
are 4-year {'sh—1. e., are born and live in fresh water for about a 
year, then go to sea, and are not observed again until they return in 
the fourth year after birth (a small proportion live to 5 years, and a 
vastly smaller proportion to 6 years), spawn on the breeding grounds 
of the Fraser and then die—a closed period of less than 4 years could 
have no appreciable effect, as it would not be a complete cycle in 
the animal's life, while 8 or 12 years, representing two or three cycles 
of their life, might possibly have a beneficial effect, although the 
experiences of the past show clearly that it is much easier to destroy a 
school of fish than it is to restore a much depleted one. 
DECREASE IN HUMPBACK SALMON CATCH. 
Another unfortunate condition has developed as a result of exces- 
sive fishing in Puget Sound of recent years, and that is the heavy 
decline in the catch of humpback salmon. These fish are caught in 
the same apparatus as used for sockeyes. 
For many years the humpbacks came in countless numbers, and 
the fishermen were able to sell but a small part of the catch. Despite
