The facts thus far given have been taken, as the reader will have observed, from Mr. Urquhart's work; and as that gentleman is a warm admirer of the system denounced by Adam Smith, he cannot be suspected of any exaggeration when presenting any of its unfavourable results. Later travellers exhibit the nation as passing steadily onward toward ruin, and the people toward a state of slavery the most, complete--the necessary consequence of a policy that excludes the mechanic and prevents the formation of a town population. Among the latest of those travellers is Mr. Mac Farlane,[57] at the date of whose visit the silk manufacture had entirely disappeared, and even the filatures for preparing the raw silk were closed, weavers having become ploughmen, and women and children having been totally deprived of employment. The cultivators of silk had become entirely dependent on foreign markets in which there existed no demand for the products of their land and labour. England was then passing through one of her periodical crises, and it had been deemed necessary to put down the prices of all agricultural products, with a view to stop importation. On one occasion, during Mr. Mac Farlane's travels, there came a report that silk had risen in England, and it produced a momentary stir and animation, that, as he says, "flattered his national vanity to think that an electric touch parting from London, the mighty heart of commerce, should thus be felt in a few days at a place like Biljek." Such is commercial centralization! It renders the agriculturists of the world mere slaves, dependent for food and clothing upon the will of a few people, proprietors of a small amount of machinery, at "the mighty heart of commerce." At one moment speculation is rife, and silk goes up in price, and then every effort is made to induce large shipments of the raw produce of the world. At the next, money is said to be scarce, and the shippers are ruined, as was, to so great an extent, experienced by those who exported corn from this country in 1847.
