The mode of finishing which was formerly, at least, in vogue in Lancashire and Cheshire may be taken as a type of the best work. (In the present day, the various methods are so widely known that they have ceased to be local, and are varied according to the quality and tannage of the goods.) The butts, which in earlier times were largely bark-tanned, are taken wet from the pits, and scoured on a rounded beam or “horse” with stone and brush, till the bloom is completely removed, and are then lightly oiled on the grain, half dried (“sammed”), laid in pile to temper, and “struck out” with the “pin,” a two-handled tool of triangular section shown in Fig. 29. The use of this tool has now been largely superseded by Wilson’s striking machine Fig. 39, in which knives or sleekers (or stones and brushes), held in jointed arms, are made to work on the butt, which is extended over a slowly rotating cylinder. The object of the pinning is not so much to remove bloom or dirt, which has been previously effected by the scouring, as to smooth and flatten the grain. After further drying, a second pinning is generally given, and the goods are then twice rolled, first with a light weight, and somewhat moist grain, and then more heavily with the grain nearly dry. This was formerly accomplished by a sort of box or car, heavily loaded with weights, supported on a smooth brass roller of about 5 inches diameter and 9 inches long, and manipulated with a long wooden handle on a floor of hard wood, or zinc plates. One type of the machines which have now almost entirely replaced this primitive contrivance is shown in Fig. 40, but is principally used for offal and common classes of goods. For better work, traversing rollers, such as Wilson’s ingenious double bed roller shown in Fig. 41, are to be preferred. After rolling, the goods are dried pretty rapidly by the aid of moderate heat, and, after polishing with a brush (hand, or machine, Fig. 42), are ready for sale. It may be pointed out that although the tools are different, the process is almost the same as that used for “_vache lissée_” in France and Belgium, and closely resembles that of currying harness leather except that the “stuffing” with fats and oil is omitted. [Illustration: FIG. 40.--Offal Roller.] In contrast with the rather elaborate method just described, we may place the American finish of red hemlock sides, which are tanned throughout with a material which yields no bloom. On these, the scouring and “striking” is altogether omitted: the goods are completely dried out from the pits, which is found to fix the dark-coloured liquor, and result in better colour; they are then damped back, and tempered, and heavily rolled under a rapidly moving pendulum roller, which polishes at the same time that it smooths the leather. The saving of cost by so simple a process is not inconsiderable. [Illustration: FIG. 41.--Wilson’s Double-bed Butt Roller.]
