The manufacture of linen in Scotland, and that of coarse woollens in the west riding of Yorkshire, are growing manufactures, of which the produce is generally, though with some variations, increasing both in quantity and value. Upon examining, however, the accounts which have been published of their annual produce, I have not been able to observe that its variations have had any sensible connection with the dearness or cheapness of the seasons. In 1740, a year of great scarcity, both manufactures, indeed, appear to have declined very considerably. But in 1756, another year of great scarcity, the Scotch manufacture made more than ordinary advances. The Yorkshire manufacture, indeed, declined, and its produce did not rise to what it had been in 1755 till 1766, after the repeal of the American stamp act. In that and the following year it greatly exceeded what it had ever been before, and it has continued to advance ever since.
The produce of all great manufactures for distant sale must necessarily depend, not so much upon the dearness or cheapness of the seasons in the countries where they are carried on, as upon the circumstances which affect the demand in the countries where they are consumed; upon peace or war, upon the prosperity or declension of other rival manufactures, and upon the good or bad humour of their principal customers. A great part of the extraordinary work, besides, which is probably done in cheap years, never enters the public registers of manufactures. The men servants who leave their masters become independent labourers. The women return to their parents, and commonly spin in order to make clothes for themselves and their families. Even the independent workmen do not always work for public sale, but are employed by some of their neighbours in manufactures for family use. The produce of their labour, therefore, frequently makes no figure in those public registers of which the records are sometimes published with so much parade, and from which our merchants and manufacturers would often vainly pretend to announce the prosperity or declension of the greatest empires.
