COLLECTION AND ANALYSIS OF DATA 



173 



considerable part of the catch has been made to the east, far outside the area with which 

 this report is concerned, and though the land station at Deception remained working 

 throughout the period, returns from the Shetland area for the first half of the season 

 have greatly diminished. So few records of Blue whales for 1929-30 and of both species 

 for 1 930- 1 are available that they are insufiicient for analysis. 



The figures for the South Shetland area are thus for eight seasons of Fin whales, 

 1922-3 to 1929-30, and for seven seasons of Blue whales, 1922-3 to 1928-9^. The 

 total number of positions recorded is 18,571, of which 11,849 relate to Fin whales 

 and 6722 to Blue whales. The figures are shown in Tables III and IV, together with
