1. Broadly speaking--of prices, i.e.--no movement of any note is perceptible, or records itself in legislative enactment until about 1520, so gradual and at first unimportant was the flow of metal from America. What did come at first was not silver so much as gold, and represents the puny and blood-stained plunder of ornaments from the natives. If this import tended to turn the balance in any way, it was in the direction of depreciation of gold as compared with silver. But during this first quarter of the sixteenth century, possibly more influence on the maintaining of equilibrium is to be attributed to the largely increased home production of silver. The silver mining in the Saxon Harz, in Bohemia, and the Tyrol, had received a strong impulse towards the close of the fifteenth century, while gold was obtained during the same period in appreciably greater quantities in the archbishopric of Salzburg, and in Hungary, as well as from Africa. [Sidenote: GENERAL STATEMENT] 2. In this second period of European bimetallic history, the centre of European monetary exchanges passes from Italy to the Netherlands. Antwerp takes the place of Venice and Florence. There is a double and deep significance in the fact. It is not merely that the trade route had changed in such a way as to lay the foundation for that development of European commerce, of which England is the highest expression in our own days; it is that by the change was provided a more effective safeguard against precipitate and overwhelming depreciation. The centre of European exchanges--Antwerp in the sixteenth, as London to-day--has always performed one supremest function--that of regulating the flow of metals from the New World by means of exporting the overplus to the East. The drain of silver to the East, discernible from the very birth of European commerce, has been the salvation of Europe, and in providing for it Antwerp acted as the safety-valve of the sixteenth-century system, as London has done since. The importance of the change of the centre of gravity and exchange from Venice to Antwerp lies therefore in this fact. Under the old system of overland and limited trade, Venice could only provide for such puny exchange and flow as the mediæval system of Europe demanded. She would have been unable to cope with such a flood of inflowing metal as the sixteenth century witnessed, and Europe would have been overwhelmed. But the foundations of the commerce of the Netherlands were laid wider. Together with Portugal she opened an extensive empire along the coasts of Africa and in the Indian East; and the very time which gave birth to the revolution in the production of the precious metals in America saw provision made for the regulation of its outflow through the commerce and exchanges of Antwerp to India. In the modern system this would be a theoretically perfect world-mechanism, and its working would be normal and healthy, and the safest indicator of commerce.
