8 MIGRATION OF ADULT SOCKEYE SALMON. 
STATISTICAL STUDY OF DATA. 
GENERAL FEATURES. 
In the following study the chief concern is with what is believed 
to be a strict and reasonably complete presentation of the facts. 
There has been no attempt to draw conclusions regarding the bear- 
ing of these facts upon the particular problems connected with the 
conservation of the sockeyes of the Fraser River. Some of the tables 
present similar data as seen from different points of view. ‘This has, 
perhaps, been carried to an extreme in order that all obtainable facts 
might be available. Other tables are presented rather as matters of 
record than as having any especial bearing on the main problems in 
hand. For the most part such tables are presented without detailed 
comment. 
RAW DATA. 
Table 1 gives for each marking station the numbers of the tags 
attached each day. As noted in the table, silver tags were used only 
at Sooke (station A). At all other stations aluminum tags were 
used, and the first few tags used at Sooke were also of aluminum, 
numbers 5 to 29, inclusive.

a Tag Nos. 5 to 29, attached at station A, and the tags used at all other stations were aluminum. 
With the exception of those noted, all tags attached at station A were of silver. : 
b This is the official list as given by the assistant having charge of the marking at this station. The rec- 
ords for Aug. 6 and subsequent dates are subject to suspicion on account of an admitted lack of veracity 
in the accounts. Previous to this date Dennis Winn was present at the markings. |
