The policy of the Dutch West India Company was to offer generous prizes for peopling the land while simultaneously forbidding competition with any of the numerous products or commodities dealt in by itself. This had much to do with determining the basic character of the conspicuous fortunes of a century and two centuries later. It followed that when native industries were forbidden or their output monopolized not only by the Dutch West India Company in New Netherlands, but by other companies elsewhere in the colonies, that ownership of land became the mainstay of large private fortunes with agriculture as an accompanying factor. Subsequently the effects of this continuous policy were more fully seen when England by law after law paralyzed or closed up many forms of colonial manufacture. The feudal character of Dutch colonization, as carried on by the Dutch West India Company, necessarily created great landed estates, the value of which arose not so much from agriculture, as was the case in Virginia, Maryland and later the Carolinas and Georgia, but from the natural resources of the land. The superb primitive timber brought colossal profits in export, and there were also very valuable fishery rights where an estate bounded a shore or river. The pristine rivers were filled with great shoals of fish, to which the river fishing of the present day cannot be compared. As settlement increased, immigration pressed over, and more and more ships carried cargo to and fro, these estates became consecutively more valuable. To encourage colonization to its colonies still further, the States General in 1635 passed a new decree. It repeated the feudal nature of the rights granted and made strong additions.
