All the gunners assert that when the gray whales appear at Ulsan on their migrations they are invariably traveling straight ahead and apparently not stopping to feed. This information, combined with the fact that little except water could be found in the stomachs, lends strong support to the theory that when upon their annual migrations the devilfish do not feed at all, and during the winter draw for nourishment upon the fat of their thick blubber. This is true of the fur seal during the breeding season, and of other water mammals. When the male fur seals arrive upon the “rookeries” at the Pribilof Islands to await the coming of the females, their bodies are covered with layer upon layer of fat. During the following four months the bulls do not leave the land and neither eat, drink nor sleep while they guard their harems, subsisting upon the fat which has been stored up on their bodies. When the animals leave in the fall to spend the winter at sea, they have become so thin through their self-enforced fasting that they are mere skeletons of their former well-fed selves. Scammon says that in the spring the blubber of the devilfish is dry and yields but comparatively little oil, as would be the case if the animals had fasted during the winter. I have no personal information as to this because in Korea these whales are not killed on their northward migrations. So many other and more valuable species can be taken during the spring that the devilfish are allowed to depart unmolested. If they do feed while on their migrations, the food in their stomachs would certainly have been discovered when the animals were cut in at the stations. The male devilfish at all times shows strong affection for the female, and when a school of males, led by one or two females, is found, if one of the latter is wounded, often the bulls refuse to leave until the cow is dead. Captain Melsom tells me that while hunting a pair of devilfish near Ulsan he shot the female, and the male would not leave his dead consort, keeping close alongside and pushing his head over her body. Later he struck the male with a harpoon, but did not get fast, and even then it returned and was finally killed. [Illustration: Captain Melsom about to lance a gray whale from the pram. ] Scammon says that when attacked in the lagoons with their young the devilfish would turn furiously upon the boats, and that almost every day injuries to the crews were reported. He gives an interesting account of two gray whales which, in February, 1856, were found aground in Magdalena Bay:
