companies. The Bank of St. George, at Genoa, and other banks founded in imitation of it, were at first only companies to make loans to, and float loans for, the Governments of the cities in which they were formed. The want of money is an urgent want of Governments at most periods, and seldom more urgent than it was in the tumultuous Italian Republics of the Middle Ages. After these banks had been long established, they began to do what we call banking business; but at first they never thought of it. The great banks of the North of Europe had their origin in a want still more curious. The notion of its being a prime business of a bank to give good coin has passed out of men's memories; but wherever it is felt, there is no want of business more keen and urgent. Adam Smith describes it so admirably that it would be stupid not to quote his words:--'The currency of a great state, such as France or England, generally consists almost entirely of its own coin. Should this currency, therefore, be at any time worn, clipt, or otherwise degraded below its standard value, the state by a reformation of its coin can effectually re-establish its currency. But the currency of a small state, such as Genoa or Hamburgh, can seldom consist altogether in its own coin, but must be made up, in a great measure, of the coins of all the neighbouring states with which its inhabitants have a continual intercourse. Such a state, therefore, by reforming its coin, will not always be able to reform its currency. If foreign bills of exchange are paid in this currency, the uncertain value of any sum, of what is in its own nature so uncertain, must render the exchange always very much against such a state, its currency being, in all foreign states, necessarily valued even below what it is worth. 'In order to remedy the inconvenience to which this disadvantageous exchange must have subjected their merchants, such small states, when they began to attend to the interest of trade, have frequently enacted, that foreign bills of exchange of a certain value should be paid, not in common currency, but by an order upon, or by a transfer in, the books of a certain bank, established upon the credit, and under the protection of the state, this bank being always obliged to pay, in good and true money, exactly according to the standard of the state. The banks of Venice, Genoa, Amsterdam, Hamburgh and Nuremburg, seem to have been all originally established with this view, though some of them may have afterwards been made subservient to other purposes. The money of such banks, being better than the common currency of the country, necessarily bore an agio, which was greater or smaller, according as the currency was supposed to be more or less degraded below the standard of the state. The agio of the bank of Hamburgh, for example, which is said to be commonly about fourteen per cent, is the supposed difference between the good standard money of the state, and the clipt, worn, and diminished currency poured into it from all the neighbouring states. 'Before 1609 the great quantity of clipt and worn foreign coin, which the extensive trade of Amsterdam brought from all parts of Europe, reduced the value of its currency about 9 per cent below
