To this I should add fourteen millions, as the increase during the Seven following years, when the average Exports were, according to my calculation, Twenty-two millions of dollars, and the average Produce Twenty-four millions; thus making the whole circulating medium, in 1810, amount to about Seventy-two millions of dollars.
The Mines, in fifteen years, appear to have produced 153,276,972, (according to the Mint Returns,) or 165,000,000, if the Average, which I have taken, of Eleven millions annually, be correct; which, with the Seventy-two millions already in existence, give a Total of Two hundred and thirty-seven millions of dollars.
The exact amount of the Exports in Specie, it is impossible to ascertain; but, during a period of disorder, which, at one time, amounted to almost total disorganization, the allowance made for unregistered Exports must be very large.
Respecting those of which an account was kept, I have obtained the only accurate information now to be procured, viz. extracts from the Registers of the Custom-Houses of Vĕrăcrūz, Ăcăpūlcŏ, Săn Blās, and Măzătlān, for which I am indebted to His Majesty's Consular Agents at those Ports. .
conceive it to have been correct, but because, in a calculation, where so much must necessarily be left to conjectural evidence, I wish to have something more than a mere supposition of my own to serve as a basis. Sixty millions are thought by most people to be very much under the real amount.
