DETAILED STUDY OF RETURNS FROM THE COMMERCIAL FISHING 
DISTRICTS. 
Two tables have been prepared for each of the marking stations, 
presenting in detail the data obtained from the marking: First, a 
table showing for each day’s marking the number and percentage 
of specimens recovered from each region and the average number of 
days required for the journey; second, a table showing the distribu- 
tion of returns according to the region from which the return was 
reported and the number of days en route. This last is given as a 
matter of record and in order to show something of the range of 
variation underlying the average rates of progress as given in various 
other tables. It is upon the data given in these tables that the 
general discussions of the routes and rates of travel which immedi- 
ately follow are based.
