The government of Holland did not, however, recognize the claims of England to jurisdiction over the whole American coast, and took measures to encourage the discovery and appropriation of additional territory, by a decree giving to discoverers of new countries the exclusive privilege of trading thither for four successive voyages, to the exclusion of all other persons. This enactment induced several merchants to fit out five small ships for coasting along the American shores in this vicinity. One of these vessels, commanded by Captain Block, soon after its arrival on the coast, was accidentally destroyed by fire. Block immediately began the construction of another, of thirty-eight-feet keel, forty-four and a half feet on deck, and eleven and a half feet beam, which was the first vessel launched in the waters of New York. She was called the Unrest, or Restless, and ploughed her keel through the waters of Hell Gate and the Sound, the pioneer of all other vessels except the bark canoes of the aboriginal inhabitants. The several ships despatched on this exploring expedition having returned to Holland, from their journals and surveys a map of a large extent of country was made, over which the Dutch claimed jurisdiction, and to which they gave the name of "New Netherlands." The owners of these vessels, as the reward of their enterprise, were granted the promised monopoly of trade hither for four voyages, to be completed within three years, commencing on January 1, 1615. These merchants seemed to have been composed in part of those who had established the first trading-post here, but having increased their number and capital, and enlarged their former designs of trade, formed themselves into a company under the name of the "United New Netherlands Company." Corstiaensen was continued the principal agent here, and they likewise established a post at the head of the river, on an island opposite the present site of Albany. Forts, of a rude description--being merely enclosures of high palisades--were erected at both places. The privileges granted to the United New Netherlands Company being, however, limited in respect to time, their establishment on this island can hardly be considered as a permanent settlement; the cabins of the settlers were nearly of equal rudeness with those of their Indian neighbors; and but few of the luxuries of civilization found their way into their habitations. The great object of the settlement was, however, successfully carried on, and stores of furs were in readiness to freight the ships on their periodical visits from the fatherland. No interruption of the friendly intercourse carried on with the Indians took place, but, on the contrary, the whites were abundantly supplied by the natives with food and most other necessaries of life, without personal labor and at trifling cost.
