The whalers found out the paths whales liked to take in the ocean, and killed them mercilessly. It was a dangerous and frightening job. Whalers would jump into a small boat and follow the whale. Once they were close to it, they would throw a harpoon that was attached to a very long rope into the whale. The end of this harpoon was not at all like a spear. It had a switch blade on the end that would stay in the whale's skin. Once the harpoon was in the whale, the whale would start swimming as fast as it could. The whale might swim day and night with no stop for several days. Eventually, the tired and hurt whale would stop. The whalers would then kill the whale with one last harpoon. When the animal died, the whalers would haul the whale onto the ship (big or small), skin it, then boil the blubber for the oil.
