passenger pigeon, was commercial hunting. Bison skins were used for industrial machine belts, clothing such as robes, and rugs. There was a huge export trade to Europe of bison hides. Old West bison hunting was very often a big commercial enterprise, involving organized teams of one or two professional hunters, backed by a team of skinners, gun cleaners, cartridge reloaders, cooks, wranglers, blacksmiths, security guards, teamsters, and numerous horses and wagons. Men were even employed to recover and recast lead bullets taken from the carcasses. Many of these professional hunters, such as Buffalo Bill Cody, killed over a hundred animals at a single stand and many thousands in their career. One professional hunter killed over 20,000 by his own count. The average prices paid the buffalo hunters from 1880 to 1884 was about as follows: For cow hides, $3; bull hides, $2.50; yearlings, $1.50; calves, 75 cents; and the cost of getting the hides to market brought the cost up to about $3.50 ($89.68 accounting for inflation) per hide. The hunter would customarily locate the herd in the early morning, and station himself about 100 yards/meters from it, shooting the animals broadside through the lungs. Head shots were not preferred as the soft lead bullets would often flatten and fail to penetrate the skull, especially if mud was matted on the head of the animal. The bison would continue to drop until either the herd sensed danger and stampeded or perhaps a wounded animal attacked another, causing the herd to disperse. If done properly a large number of bison would be felled at one time. Following up were the skinners, who would drive a spike through the nose of each dead animal with a sledgehammer, hook up a horse team, and pull the hide from the carcass. The hides were dressed, prepared, and stacked on the wagons by other members of the organization. For a decade after 1873, there were several hundred, perhaps over a thousand, such commercial hide hunting outfits harvesting bison at any one time, vastly exceeding the take by Native Americans or individual meat hunters. The commercial take arguably was anywhere from 2,000 to 100,000 animals per day depending on the season, though there are no statistics available. It was said that the Big .50s were fired so much that hunters needed at least two rifles to let the barrels cool off; The Fireside Book of Guns
