It must be remembered, hovv^ever, that the numbers of Sei whales taken in any season depend partly on the numbers of other species available to the whalers. Further the Sei whale has been almost notorious for suddenly appearing in large numbers on whaling grounds where it was previously scarce. For instance, it is said to have appeared at South Georgia for the first time in season 1913-14; and to have first arrived in great numbers off the Hebrides and Shetlands in the northern hemisphere in 1906. But it appears possible that the accounts of these sudden appearances are based on inac-. Apr MdL| ' Jun â Jul Aug ' Sep Oct Fig. 108. Sei whale. Monthly catches at Natal, 1918-26. Nov curate observation. In the early days of whaling at South Georgia, Right whales and Humpbacks were so plentiful that the comparatively low powered catchers had no cause to seek for whales at any great distance from the whaling stations. The reason for the sudden abundance of Sei whales at the Scottish whaling stations is given by Haldane (1909) as the extension of fishing outside a previous 40-mile limit. He says, "B. borealts was more abundant, B. nmsciihis scarcer than last year; the reason given for this is that during the time of the 40-mile limit there were plenty of B. musculus within the limit, doubtless feeding on the herring which were abundant on the west coast of Shetland, while beyond the 40 miles B. borealts were plentiful and B. musailus not so ; In both these localities, then, the apparent abundance may have been due merely to.
