The security of life and property arising from mild laws, and, an equal administration of justice, had encouraged activity and industry. In continual contest with the ocean and rapid rivers, which poured their violence on the neighboring lowlands, and whose force it was requisite to break by embankments and canals, this people had early learned to observe the natural objects around them; by industry and perseverance to defy an element of superior power; and like the Egyptian, instructed by his Nile, to exercise their inventive genius and acuteness in self-defence. The natural fertility of their soil, which favored agriculture and the breeding of cattle, tended at the same time to increase the population. Their happy position on the sea and the great navigable rivers of Germany and France, many of which debouched on their coasts; the numerous artificial canals which intersected the land in all directions, imparted life to navigation; and the facility of internal communication between the provinces, soon created and fostered a commercial spirit among these people. The neighboring coasts, Denmark and Britain, were the first visited by their vessels. The English wool which they brought back employed thousands of industrious hands in Bruges, Ghent, and Antwerp; and as early as the middle of the twelfth century cloths of Flanders were extensively worn in France and Germany. In the eleventh century we find ships of Friesland in the Belt, and even in the Levant. This enterprising people ventured, without a compass, to steer under the North Pole round to the most northerly point of Russia. From the Wendish towns the Netherlands received a share in the Levant trade, which, at that time, still passed from the Black Sea through the Russian territories to the Baltic. When, in the thirteenth century, this trade began to decline, the Crusades having opened a new road through the Mediterranean for Indian merchandise, and after the Italian towns had usurped this lucrative branch of commerce, and the great Hanseatic League had been formed in Germany, the Netherlands became the most important emporium between the north and south. As yet the use of the compass was not general, and the merchantmen sailed slowly and laboriously along the coasts. The ports on the Baltic were, during the winter months, for the most part frozen and inaccessible. Ships, therefore, which could not well accomplish within the year the long voyage from the Mediterranean to the Belt, gladly availed themselves of harbors which lay half-way between the two.
