available, and Table 15 and Fig. 5 are therefore drawn up for the four seasons, 1934-8. 

 ' Factories' days' are not given in the statistics for seasons prior to 1934-5, so the earlier 

 seasons, when some ships worked in area V, are not included. During the period 

 1934-8, however, it is clear that Blue whales, though scarce in area II, were taken in

large numbers between 20 and 40 E in area III, and again between 80 and ioo° E in 

 area IV. This suggests a grouping very similar to that of Humpbacks. Fin whales 

 dominate the catches in area II between 20 and 50 W; in area III there is a maximum 

 in about the same position as the Blue whale maximum, but in area IV the maximum 

 for Fin whales is some distance to the east of that for Blue whales. The well-known 

 scarcity of whales about 60 and 70 E is clearly seen. The graph of ' whales per day ' gives
