TABLE III.
Comparison of the amount of oil estimated (from the description of the catches) to be the yield which could be reasonably expected from the whales killed by each company at South Georgia during the season of 1913-14 with the amount of oil stated by the Stipendiary Magistrate to have been actually produced by each com- pany during the said season.

It is first necessary to prove that the amount of oil assumed to be yielded by each whale in these estimates is a fair average one. Major Barrett-Hamilton examined that part of the catch of the South Georgia Company which was obtained between 15th November, 1913, and 16th January, 1914, and he has recorded the measurements of 57 humpbacks, 184 finners, and 50 blue whales, or 291 whales in all. As shown above, 19 of the humpbacks, 6 of the finners, and 15 of the blue whales, i.e., 40 of all kinds, or 18.7 per cent of the total catch of 291 whales, were sexually immature. Entries from Major Barrett-Hamilton's Journal are cited below (p. 167), and these show that during part of the time the method of reducing the whales was a very wasteful one. Table III. shows that in spite of the presence of at least forty immature whales in the catch, and of wasteful reduc- tion during a part of the season, this Company produced an amount of oil 1 per cent. more than that estimated as reasonable to expect from the description of its catch in the season of 1913-14. The yield per whale assumed in the estimates must, therefore, be rather below, and certainly cannot be above, the actual average yield of full-grown specimens.
Certain of the figures, indeed, suggest that the amount assumed in the esti- mates to be the average yield of oil per whale is considerably less than the real average yield. Thus, the report made on the whales captured by the Tönsberg Company during the season 1913-14 (of which report a summary is given below at p. 168) gives the measurements of 69 humpbacks, 144 finners, and 36 blue whales. Of these whales 26 humpbacks, 2 finners, and 12 blue whales, or about 16 per cent. of the whole number, appear to have been sexually immature. Nevertheless, the actual output of oil of the Tönsberg Company in the season of 1913-14 was 7 per cent. greater than their estimated output.
Again, in the season of 1911-12 (Table II) the actual output of oil of the Southern Whaling & Sealing Company, Limited, was 9 per cent. greater than that which I have estimated as reasonable to expect from the description of its catch. In his report on the season the Stipendiary states that the boats of this Company did not arrive until January; since whales were then very plentiful the Company's whalers may have selected large specimens in order to obtain a good profit on their short season. The catch was, allowing for the late start, both numerically and relatively a small one; and the results obtained show, in my opinion, the floating factory (n. 164) working at its best.
Finally, in the season of 1911-12, the Ocean Whaling Company produced an amount of oil no less than 16.5 per cent. in excess of the amount which I have estimated as reasonable to expect from the description of their catch.
