We shall not attempt to describe the silk manufacture, which is on the same principles as all other textiles, except that less work can be done by machinery. But it is one of the most pleasant and picturesque of all our manufacturing operations. The long light rooms in which the weaving is conducted are scrupulously clean and of a pleasant temperature,--no dust, no motes are flying about. The girls in short sleeves, in the course of their work are, as it were, obliged to assume a series of graceful attitudes. The delicacy of their work, and the upward position in which they hold them, render their hands white and delicate, and the atmosphere has something of the same effect on their complexion. Many of the greatest beauties of Belgravia might envy the white hands and taper fingers to be found in a silk mill. Unfortunately this trade, which in factory work is healthy and well paid, is, more than any other, subject to the vicissitudes of fashion. The plain qualities suffer from such changes less than the rich brocades and fancy patterns. It must be remarked that, although the repeal of protective duties to eighteen per cent. produced a temporary depressing effect on the trade of Macclesfield, the general silk trade has largely increased ever since 1826, and has spread over a number of counties where it was before unknown, and has become an important article of export even to France. An example of the readiness with which, in these railroad days, a manufacture can be transplanted, was exhibited at Tewkesbury four years ago. The once- fashionable theatre of that decayed town was being sold by auction; it hung on the auctioneer's hammer at so trifling a sum that one of the new made M.P.'s of the borough bought it. Having bought it, for want of some other use he determined to turn it into a silk mill. In a very short space of time the needful machinery was obtained from Macclesfield, with an overseer. While the machinery was being erected, a bevy of girls were acquiring the art of silk weaving, and, in less than twelve months, five or six hundred hands were as regularly engaged in this novel process, as if they had been so engaged all their lives. Without railroads, such an undertaking would have been the work of years, if possible at all. Raw silk is obtained from Italy, from France in small quantities, as the exportation of the finest silk is forbidden, from China, from India in increasing quantities, and from Brusa in Asia Minor through Constantinople.
