yet it is several miles upriver from the lower fishing limits, and therefore gives a chance 
to test whether the marked fish ever run toward salt water. 
Of the 59 fish marked and liberated on August 14, there were 25 chinook salmon 
(1 Oncorhyiichus tschawytscha ) , 16 silver salmon ( O . kisutch), and 18 steelheads ( Salmo 
gairdneri). These fish ranged in total length from 41 to 103 cm. for the chinooks, 
47 to 78 cm. for the silvers, and 71 to 90 cm. for the steelheads. The largest chinook 
weighed 35 pounds. The fish, while few in number, were well distributed as regards size, 
Information as to the import of the experiment was given out to the fishery interests 
on the Columbia. Fishermen were requested to record the place and details of the 
catch of any marked fish, to note any injuries or other facts of interest, and to report 
the same to me. Fishermen were also requested to send in the marking buttons with 
the tails of the fish. The various salmon-packing firms were especially helpful in 
reporting catches and in forwarding the marking buttons.® 
Seventeen out of the 59 fish marked were retaken and reported to me. This 
number retaken represents 29 per cent of the fish liberated, a very favorable propor- 
tion considering the 12 to 15 days of closed season following the 25th of August. Of 
these fish 6 were chinooks, 6 were silver salmon, and 5 were steelheads. The time of 
the retaking extended from the date of the marking, August 14, to October 10, a total 
of 57 days. The general record of all the fish retaken is presented in table 1.
