370. One of the remedies employed by the masters against the occurrence of combinations, is to make engagements with their men for long periods and to arrange them in such a manner, that these contracts shall not all terminate together. This has been done in some cases at Sheffield, and in other places. It is attended with the inconvenience to the masters that, during periods when the demand for their produce is reduced, they are still obliged to employ the same number of workmen. This circumstance, however, frequently obliges the proprietors to direct their attention to improvements in their works: and in one such instance, within the author's knowledge, a large reservoir was deepened, thus affording a more constant supply to the water-wheel, whilst, at the same time, the mud from the bottom gave permanent fertility to a piece of land previously almost barren. In this case, not merely was the supply of produce checked, when a glut existed. but the labour was, in fact, applied more profitably than it would have been in the usual course. 371. A mode of paying the wages of workmen in articles which they consume, has been introduced into some of our manufacturing districts, which has been called the truck system. As in many instances this has nearly the effect of a combination of the masters against the men, it is a fit subject for discussion in the present chapter: but it should be carefully distinguished from another system of a very different tendency, which will be first described. 372. The principal necessaries for the support of a workman and his family are few in number, and are usually purchased by him in small quantities weekly. Upon such quantities, sold by the retail dealer, a large profit is generally made; and if the article is one whose quality, like that of tea, is not readily estimated, then a great additional gain is made by the retail dealer selling an inferior article.
