At Home - Bill Bryson [63]
In common with other types of whales, the oil of sperm whales was also craved by industry as an emollient in the manufacture of soaps and paints and as lubrication for machinery. Whales also yielded gratifying quantities of baleen, a bonelike substance taken from the upper jaw, which provided a sturdy but flexible material for corset stays, buggy whips, and other items that needed a measure of natural springiness.
Whale oil was an American speciality, both to produce and to consume. It was whaling that brought so much early wealth to New England ports like Nantucket and Salem. In 1846, America had more than 650 whaling ships, roughly three times as many as all the rest of the world put together. Whale oil was taxed heavily throughout Europe, so people there tended to use colza (a type of oil made from cole seeds) or camphene (a derivative of turpentine), which made an excellent light, though it was highly unstable and tended, unnervingly, to explode.
Nobody knows how many whales were killed during the great age of whaling, but one estimate suggests that about three hundred thousand were slaughtered in the four decades or so leading to 1870. That may not seem an especially vast number, but then whale numbers were not vast to begin with. In any case, the hunting was enough to drive many species to the edge of extinction. As whale numbers dwindled, whaling voyages grew longer and longer—up to four years became common and five years not unknown—and whalers were driven to search the loneliest corners of the most distant seas. All this translated into greatly increased costs. By the 1850s a gallon of whale oil sold for $2.50—half an average worker’s weekly wage—yet still the remorseless hunt continued. Many species of whale—possibly all—would have vanished forever but for a sequence of unlikely events that began in Nova Scotia in 1846 when a man named Abraham Gesner invented what for some time would be the most valuable product on Earth.
Gesner was a physician by profession, but he had an odd passion for coal geology. While experimenting with coal tar—a useless, sticky residue left over from the processing of coal into gas—he devised a way to distill it into a combustible liquid that he called (for uncertain reasons) kerosene. Kerosene burned beautifully and gave a light as strong and steady as that of whale oil, but with the potential to be produced much more cheaply. The problem was that production in volume seemed impossible. Gesner made enough to light the streets of Halifax and eventually started a plant in New York City, which ensured his personal prosperity, but kerosene squeezed from coal was never going to be more than a marginal product in the world at large. By the late 1850s, total American output was just six hundred barrels a day. (Coal tar itself, on the other hand, soon found applications in a vast range of products—paints, dyes, pesticides, medicines, and more. Coal tar became the basis of the modern chemical industry.)
Into this quandary strode another unexpected hero—a bright young man named George Bissell, who had just stepped down as superintendent of schools in New Orleans after a brief but distinguished career in public education. In 1853, on a visit to his hometown of Hanover, New Hampshire, Bissell called on a professor at his alma mater, Dartmouth College,
