The places at which the capture of whales, or "whale-fishery," is carried on. The principal are the coasts of Greenland and Davis Straits, for the northern right whale; Bermuda, for hump-backs; the Cape of Good Hope and the Australian seas, for the southern right whale; the North Pacific, for the Japanese right whale; and various places in the intertropical and southern seas, for the sperm-whale. But the constant persecution to which these animals are subjected causes a frequent change in their habitats. They have been nearly exterminated, or rendered so scarce as not to be worth following, in many districts where they formerly most abounded, and in order to make the trade remunerative, new grounds have to be continually sought. Maury's "whale charts" give much valuable information on this subject.
