Code 2600 applies to employers engaged in processing fur.  In general, the procedure of fur processing consists of soaking raw fur in a solution of salt water.  The fur is then pulled and kicked in “kicking” machines to soften the pelts.  Flesh still adhering to the hide is cut and scraped off by hand or in “fleshing” machines.  When this operation has been completed, the moisture is removed from the pelts by centrifugal extractors and, after being allowed to dry, the skins are stretched by pulling and the loose and long hair is brushed or plucked out.  When the skins are thoroughly dry, the flesh side is rubbed with fish oil to soften the skins.  The hides are then tumbled with sawdust to absorb the excess oil and to brighten the fur.  Sometimes, the skins are unhaired or sheared to produce fur of uniform length and brushed prior to tumbling.  They are then examined, and any torn sections are repaired by sewing machines, after which they are prepared for shipment.

This classification also applies to hatters’ fur manufacturing - rabbit or similar short-haired animal pelts are received, sorted, and softened in tumblers with water and sawdust, split open with hand knives, and laid flat.  Hair (which is of longer length than the soft fur found close to the skin) is sheared off by machine, leaving a soft downy-like fur on the skin.  The fur is then carroted (a process to stiffen it with a mixture of nitric acid and hydrogen peroxide that is applied by hand brush, spray, or dipping it into vats).
