Of all those expensive and uncertain projects, however, which bring bankruptcy upon the greater part of the people who engage in them, there is none perhaps more perfectly ruinous than the search after new silver and gold mines. It is perhaps the most disadvantageous lottery in the world, or the one in which the gain of those who draw the prizes bears the least proportion to the loss of those who draw the blanks: for though the prizes are few and the blanks many, the common price of a ticket is the whole fortune of a very rich man. Projects of mining, instead of replacing the capital employed in them, together with the ordinary profits of stock, commonly absorb both capital and profit. They are the projects, therefore, to which of all others a prudent lawgiver, who desired to increase the capital of his nation, would least choose to give any extraordinary encouragement, or to turn towards them a greater share of that capital than what would go to them of its own accord. Such in reality is the absurd confidence which almost all men have in their own good fortune, that wherever there is the least probability of success, too great a share of it is apt to go to them of its own accord.
But though the judgment of sober reason and experience concerning such projects has always been extremely unfavourable, that of human avidity has commonly been quite otherwise. The same passion which has suggested to so many people the absurd idea of the philosopher’s stone, has suggested to others the equally absurd one of immense rich mines of gold and silver. They did not consider that the value of those metals has, in all ages and nations, arisen chiefly from their scarcity, and that their scarcity has arisen from the very small quantities of them which nature has anywhere deposited in one place, from the hard and intractable substances with which she has almost everywhere surrounded those small quantities, and consequently from the labour and expense which are everywhere necessary in order to penetrate to and get at them. They
