"A calamity has fallen on Madeira unparalleled in its history. The vintage, the revenue of which furnished the chief means for providing subsistence for its inhabitants, has been a total failure, and the potato crop, formerly another important article of their food, is still extensively diseased. All classes, therefore, are suffering, and as there are few sources in the island to which they can look for food, clothing, and other necessaries of life, their distress must increase during the winter, and the future is contemplated with painful anxiety and apprehension. Under such appalling prospects, the zealous and excellent civil Governor, Snr. José Silvestre Ribeiro, addressed a circular letter to the merchants of Madeira on the 24th of August last, for the purpose of bringing the unfortunate and critical position of the population under his government to the notice of the benevolent and charitable classes in foreign countries, and in the hope of exciting their sympathy with, and assistance to, so many of their fellow creatures threatened with famine." Such are the necessary consequences of a system which looks to compelling the whole population of a country to employ themselves in a single pursuit--all cultivating the land and all producing the same commodity; and which thus effectually prevents the growth of that natural association so much admired by Adam Smith. It is one that can end only in the exhaustion of the land and its owner. When population increases and men come together, even the poor land is made rich, and thus it is, says M. de Jonnes, that "the powers of manure causes the poor lands of the department of the Seine to yield thrice as much as those of the Loire."[49] When population diminishes, and men are thus forced to live at greater distances from each other, even the rich lands become impoverished; and of this no better evidence need be sought than that furnished by Portugal. In the one case, each day brings men nearer to perfect freedom of thought, speech, action, and trade. In the other they become from day to day more barbarized and enslaved, and the women are more and more driven to the field, there to become the slaves of fathers, husbands, brothers, and even of sons.
