Henry of Huntingdon, writing in the reign of Henry II., says that England possessed mines of copper, iron, lead, and silver, the last metal in very small quantities. “Silver, however, is received from the neighbouring ports of Germany, with which an extensive commerce is carried on by the Rhine in the abundant product of fish and meat, as well as of fine wool and fat cattle which Britain supplies.... Britain also furnishes large quantities of very excellent jet of a black and brilliant hue.” One observes that he does not include slaves among the exports. That trade had therefore disappeared. The statement of this Chronicle stands good for four hundred years. The staple exports of England continued to be wool, hides, iron, and tin. Sometimes grain was also exported. England, for many centuries, was the greatest wool-producing country of Europe. The chief reason appears to have been the comparative peace enjoyed by the island at a time when the rest of Western Europe was continually devastated by wars of all kinds, namely, civil wars, foreign wars, wars between barons, wars between towns. The Englishman was the only farmer who could keep his sheep. Therefore it happened that the German Ocean was always covered with light ships sailing to and fro laden with wool. Flanders was the manufacturing country which received the wool; when there was a break in the friendly relations of England and Flanders half the Flemish people were thrown out of work. England sent abroad money by means of wool: the tribute to the Pope was paid in sacks of wool sent to Bruges and there sold. In the year 1343 the Deans of York, Lichfield, and Salisbury, and the Archdeacon of Canterbury, who were all non-resident Italians, received their stipends in wool. Even the taxes were calculated by sacks of wool. Many efforts were made to make England a manufacturing country, but for a long time in vain. Henry I. established the cloth fair at St. Bartholomew’s. Edward III. brought weavers from Flanders and settled them at Norwich. One has only to stand before the Guildhalls of Bruges and Ghent, or in the splendid Hall of the Drapiers of Ypres, to understand how great an industry was this of the cloth manufacture, which the English people were so slow in learning. Up to the fifteenth century the English ships went up to Bruges by canal. When in the sixteenth century Maximilian dammed the canal at Sluys, the English vessels then went to Antwerp. The chief town of the wool trade was called the Staple. It was changed from time to time: Bruges, St. Omer, Calais, Antwerp, were all in succession Staples. When Antwerp was sacked in 1567 and 1585, London took its place.
