As a rule the voyage to the Pacific whaling waters was round Cape Horn, though occasionally a vessel made its way to the eastward and rounded the Cape of Good Hope. Almost always the world was circumnavigated before return. In early days the Pacific whalers found their game in plenty along the coast of Chili; but in time they were forced to push further and further north until the Japan Sea and Bering Sea became the favorite fishing places.
The whale was usually first sighted by the lookout in the crow’s nest. A warm-blooded animal, breathing with lungs, and not with gills, like a fish, the whale is obliged to come to the surface of the water periodically to breathe. As he does so he exhales the air from his lungs through blow-holes or spiracles at the top of his head; and this warm, moist air, coming thus from his lungs into the cool air, condenses, forming a jet of vapor looking like a fountain, though there is, in fact, no spout of water. “There she blows! B-l-o-o-o-ws! Blo-o-ows!” cries the lookout at this spectacle. All is activity at once on deck, the captain calling to the lookout for the direction and character of the “pod” or school. The sperm whale throws his spout forward at an angle, instead of perpendicularly into the air, and hence is easily distinguished from right whales at a distance. The ship is then headed toward the game, coming to about a mile away. As the whale, unless alarmed, seldom swims more than two and a half miles an hour, and usually stays below only about forty-five minutes at a time, there is little difficulty in overhauling him. Then the boats are launched, the captain and a sufficient number of men staying with the ship.
