The very terms used in this manufacture have an ancient smack about them. The sheepskins used are called "pelts," and are supplied by the "fell-monger." They are first immersed for a while in a solution of lime, and then hung over nothing less primitive than the half of a tree, sawn lengthwise, while a "flesher" scrapes and "couches" them (_i.e._, removes all wrinkles). They are then "split," the inner skin, called the "mutton" or "lining," being adroitly separated from the outer "grain." This "lining" is next "frized" (_i.e._, rubbed), to remove all fat, then again "limed," and thoroughly washed. It is then "squeezed" and "punched" till "the water is killed," then soaked with cod-liver oil. This causes fermentation to set in, during which the skins have to be carefully watched by men whose duty it is to "turn the heats" before "burning" takes place. Alkaline treatment follows, and, finally, the skins are "ground," _i.e._, pared with a round knife and smoothed with a wooden "scurfer," being sprinkled the while with water from a bunch of butchers' broom, called by its old English name "knee-holm." They are then packed in "kips" of thirty apiece, and put on the market. Before "grounding," the taste of the ordinary customer, who likes a pretty white "shammy," is consulted by bleaching most of the skins with sulphur. Appearance, however, is thus dearly purchased, for sulphur blackens silver, besides shortening the life of the skin. The useful colour is dark brown. "For parchment the 'linings' are tied in a frame by strings fastened round grooved pegs, on the same principle as a Spanish windlass.... After being scraped with a 'half-round' knife, dried, 'shaved,' dabbed with whitewash, and heated in a stove to remove the grease, they are then scalded and rubbed with pumice until they are fine and smooth.... The parchment workers wear clogs, sheepskin leggings, and 'basil' aprons. A basil is an unsplit tanned sheepskin. In this well-managed factory all the refuse goes to make soap, glue, dubbin, or manure, and not one scrap of material is wasted."[168] [Footnote 168: Prof. Hughes' _Geography of Cambridgeshire_, p. 106.]
