In many different manufactures, however, the operations are so much alike, that the workmen could easily change trades with one another, if those absurd laws did not hinder them. The arts of weaving plain linen and plain silk, for example, are almost entirely the same. That of weaving plain woollen is somewhat different; but the difference is so insignificant, that either a linen or a silk weaver might become a tolerable workman in a very few days. If any of those three capital manufactures, therefore, were decaying, the workmen might find a resource in one of the other two which was in a more prosperous condition; and their wages would neither rise too high in the thriving, nor sink too low in the decaying manufacture.
