DISCOVERY REPORTS 



Ruud's table I it is called 'number of days with catch'. The totals for the two seasons 

 are divided by the factories' days to give 'whales per day'. The upper part of Fig. 3 

 shows the Humpbacks killed per day, and indicates also the catches of the three species

■ HUMPBACK □ BLUE 4-FIN + HUMPBACK 



Fig. 3. Comparison, in every io c of longitude, between Humpbacks killed per day in 1936-8 and Humpbacks 

 shot at per day during the ' William Scoresby's ' whale-marking cruises in 1934-8. From Tables 1 1 and 12. 



combined. Since Humpbacks are caught in considerably smaller numbers than the 

 other two, the vertical scale for this species is doubled so that its relative distribution 

 can be more easily compared.
