It does this chiefly in the three following ways. First, by restraining the competition in some employments to a smaller number than would otherwise be disposed to enter into them; secondly, by increasing it in others beyond what it naturally would be; and, thirdly, by obstructing the free circulation of labour and stock, both from employment to employment, and from place to place. First, The policy of Europe occasions a very important inequality in the whole of the advantages and disadvantages of the different employments of labour and stock, by restraining the competition in some employments to a smaller number than might otherwise be disposed to enter into them. The exclusive privileges of corporations are the principal means it makes use of for this purpose. The exclusive privilege of an incorporated trade necessarily restrains the competition, in the town where it is established, to those who are free of the trade. To have served an apprenticeship in the town, under a master properly qualified, is commonly the necessary requisite for obtaining this freedom. The bye-laws of the corporation regulate sometimes the number of apprentices which any master is allowed to have, and almost always the number of years which each apprentice is obliged to serve. The intention of both regulations is to restrain the competition to a much smaller number than might otherwise be disposed to enter into the trade. The limitation of the number of apprentices restrains it directly. A long term of apprenticeship restrains it more indirectly, but as effectually, by increasing the expense of education. In Sheffield, no master cutler can have more than one apprentice at a time, by a bye-law of the corporation. In Norfolk and Norwich, no master weaver can have more than two apprentices, under pain of forfeiting five pounds a-month to the king. No master hatter can have more than two apprentices anywhere in England, or in the English plantations, under pain of forfeiting five pounds a-month, half to the king, and half to him who shall sue in any court of record. Both these regulations, though they have been confirmed by a public law of the kingdom, are evidently dictated by the same corporation-spirit which enacted the bye-law of Sheffield. The silk-weavers in London had scarce been incorporated a year, when they enacted a bye-law, restraining any master from having more than two apprentices at a time. It required a particular act of parliament to rescind this bye-law.
