Thus encouraged, he pursued his way up the river, gazing with wondering delight upon its glorious scenery, and listening with gradually fading hope to the stories of the natives who flocked to the water to greet him. The stream narrowed, and the water grew fresh, and long before he anchored below Albany, Hudson had abandoned the belief that he was in the Northwest passage. From the anchorage, a boat's crew continued the voyage to the mouth of the Mohawk. Hudson was satisfied that he had made a great discovery--one that was worth fully as much as finding the new route to India. He was in a region upon which the white man's eye had never rested before, and which offered the richest returns to commercial ventures. He hastened back to New York Bay, took possession of the country in the name of Holland, and then set sail for Europe. He put into Dartmouth in England, on his way back, where he told the story of his discovery. King James I. prevented his continuing his voyage, hoping to deprive the Dutch of its fruits; but Hudson took care to send his log-book and all the ship's papers over to Holland, and thus placed his employers in full possession of the knowledge he had gained. The English at length released the _Half Moon_, and she continued her voyage to the Texel. The discovery of Hudson was particularly acceptable to the Dutch, for the new country was rich in fur-bearing animals, and Russia offered a ready market for all the furs that could be sent there. The East India Company, therefore, refitted the _Half Moon_ after her return to Holland, and despatched her to the region discovered by Hudson on a fur trading expedition, which was highly successful. Private persons also embarked in similar enterprises, and within two years a prosperous and important fur trade was established between Holland and the country along the Mauritius, as the great river discovered by Hudson had been named, in honor of the Stadtholder of Holland. No government took any notice of the trade for a while, and all persons were free to engage in it. Among the adventurers employed in this trade was one Adrian Block, noted as one of the boldest navigators of his time. He made a voyage to Manhattan Island in 1614, then the site of a Dutch trading post, and had secured a cargo of skins with which he was about to return to Holland, when a fire consumed both his vessel and her cargo, and obliged him to pass the winter with his crew on the island. They built them log huts on the site of the present Beaver street, the first houses erected in New York, and during the winter constructed a yacht of sixteen tons, which Block called the _Onrust_--the "Restless." In this yacht Block made many voyages of discovery, exploring the coasts of Long Island Sound, and giving his name to the island near the eastern end of the sound. He soon after went back to Europe.
