PERCENTAGE OF RETURNS. 
Table 3 shows the percentage of returns from each day’s markin 
at each station. The data from which the percentages were obtaine

was quite uniformly successful. This is especially true with that 
done at stations B and D. The marking done at station A suffered 
somewhat in efficiency for a few days at the time the change was 
made in the personnel but otherwise is satisfactory. The records 
from station E show a sudden diminution in the percentage of re- 
turns on August 8 and for the following three days on which fish

(note to Table 1, station C), the accuracy of the August records for 
station C is subject to considerable question, and the operator at 
this point has admitted reporting incorrectly the number of fish 
marked on August 6. But 2 out of 164 reported marked on this date
