whales. Once a whale was sighted, rowing boats were sent from the shore. If the whale was successfully killed it was towed ashore, flensed (i.e., the blubber was cut off), and the blubber boiled in cauldrons known as "try pots". Even when whales were caught far offshore, the blubber was still boiled on shore well into the 18th century. New Bedford whaling was established when prominent Nantucket whaling families moved their operations to the town for economic reasons, and made New Bedford the fourth busiest port in the United States. In Herman Melville's novel Moby-Dick the narrator begins his whaling voyage from New Bedford. In the late 1870s, schooners began hunting humpbacks in the Gulf of Maine. In 1880, with the decline of menhaden fish, steamers began to switch to hunting fin and humpback whales using bomb lances. This has been called "shoot-and-salvage" because of the high-rate of loss due to whales sinking, lines breaking, etc. The first such whale hunting ship was the steamer Mabel Bird, which towed whale carcasses to an oil processing plant in Boothbay Harbor. At its height in 1885 four or five steamers were engaged in whale fishery at Boothbay Harbour, dwindling to one by the end of the decade. Over 100 whales were killed annually during some years. The fishery ended in the late 1890s. Technological advancement In the 1850s, the Euro–American whalemen began a serious attempt at catching rorquals such as the blue whale and fin whale. In the 1860s Captain Thomas Welcome Roys invented a rocket harpoon, making a significant contribution to the development of the California whaling industry. In 1877, John Nelson Fletcher, a pyrotechnist, and a former Confederate soldier, Robert L. Suits, modified Roys's rocket, marketing it as the "California Whaling Rocket". The rocket was highly effective in killing whales. Danish naval officer Captain Otto C. Hammer and the Dutchman Captain C. J. Bottemanne also imitated Roys' rocket harpoon. Hammer formed the Danish Fishing Company, which operated from 1865 to 1871. Botteman formed the Netherlands Whaling Company, which operated from 1869 to 1872. Legacy In 1996, the New Bedford Whaling National Historical Park was established, offering exhibits on the history of the "City that Lit the World". Pacific Northwest Whaling on the Pacific Northwest Coast encompassed both aboriginal and commercial whaling. The indigenous peoples of this coast have whaling traditions dating back millennia.
