Captain John Smith's friend, the Englishman Henry Hudson, while in the employ of the Dutch East India Company, in his vessel of ninety tons, the Half-Moon, being in search of a northwest passage south of Virginia, cast anchor outside of Sandy Hook, September 3, 1609, and on the 11th passed up through the Narrows into the present bay of New York. Under the firm conviction that he was on his way to the long-sought Cathay, a day later he entered the Hudson River, where now stands the proud metropolis of America. As the Half-Moon ascended the river the water lost its saltness, and by the time they were anchored where the city of Albany now stands all hopes of Cathay faded from the heart of the mariner. Englishmen called this river in honor of its discoverer, but the Dutch gave it the name of North River, the Delaware had been discovered and named South River. Thus, while in 1609 Samuel Champlain was exploring the lake which bears his name, Hudson was ascending his river upon the southern water-shed. The historian tells us that these bold explorers penetrated the wilderness, one from the north and the other from the south, to within one hundred miles of each other. The same historian (Dr. Lossing) says: "The most remote source of the extreme western branch of our noble river is Hendricks Spring, so named in honor of Hendricks Hudson. We found Hendricks Spring in the edge of a swamp, cold, shallow, about five feet in diameter, shaded by trees, shrubbery, and vines, and fringed with the delicate brake and fern. Its waters, rising within half a mile of Long Lake, and upon the same summit-level, flow southward to the Atlantic more than three hundred miles; while those of the latter flow to the St. Lawrence, and reach the same Atlantic a thousand miles away to the far northeast." Since Dr. Lossing visited the western head of the Hudson River, the true and highest source of the stream has probably been settled by a gentleman possessing scientific acquirements and inflexible purpose. On the plateau south of Mount Marcy, State-Surveyor Colvin found the little Lake Tear-of-the-Clouds to be the loftiest sheet of water in the state, -- four thousand three hundred and twenty-six feet above the sea, -- and proved it to be the lake-head of the great river Hudson. A second little pond in a marsh on a high plateau, at the foot of Mount Redfield, was also discovered, -- "margined and embanked with luxuriant and deep sphagnous moss," -- which was named by the party Moss Lake. It was found to flow into the Hudson. A beautiful little bivalve shell, three-sixteenths of an inch in diameter, of an undescribed species, was found in the pellucid water, and thus a new shell was handed over to conchology, and a new river source to geography, in the same hour. This pool is four thousand three hundred and twelve feet above tide-water, and only a few feet lower than its sister, Tear-of-the-Clouds -- the highest source of the Hudson.
