The causes of the decreasing means of subsistence are but too obvious; and the checks which keep the population down to the level of these decreasing resources, may be traced with nearly equal certainty, and will appear to include almost every species of vice and misery.’ Happy country, secured by the very nature of its government from the terrors of increasing population, and where every species of vice and misery, wisely anticipated, on the principle that the imagination of a thing is worse than the reality, takes away all fear of any greater evils than those they already endure! In the same chapter, he says, that in Persia ‘the lower classes of people are obliged to defer marriage till late; and that it is only among the rich that this union takes place early. The dreadful convulsions to which this country has been subject for many hundred years, must have been fatal to her agriculture. The periods of repose from external wars, and internal commotions have been short and few, and even during the times of profound peace, the frontier provinces have been constantly subject to the ravages of the Tartars.—The effect of this state of things is such as might be expected. The proportion of uncultivated to cultivated land, Sir John Chardin states to be, ten to one; and the mode in which the officers of the state and private owners let out their lands to husbandmen, is not that _which is best calculated to reanimate industry_. The other checks to population in Persia are nearly the same as those in Turkey. _The superior destruction of the plague in Turkey is perhaps nearly balanced by the greater frequency of internal commotions in Persia._’
