From the mouth of Columbia River, Gray sailed to Nootka Sound, where he communicated his recent discoveries to the Spanish commandant, Quadra; to whom he also gave charts and descriptions of Bulfinch's Harbor, and of the mouth of the Columbia. He departed for Canton in September, and thence sailed to the United States. The voyages of Kendrick and Gray were not profitable to the adventurers, yet not fruitless of benefit to their country. They opened the way to subsequent enterprises in the same region, which were eminently successful. And, in another point of view, these expeditions were fraught with consequences of the utmost importance. Gray's discovery of Columbia River was the point most relied upon by our negotiators in a subsequent era for establishing the claim of the United States to the part of the continent through which that river flows; and it is in a great measure owing to that discovery that the growing State of Oregon is now a part of the American Republic. From the date of the discovery of Columbia River to the war of 1812, the direct trade between the American coast and China was almost entirely in the hands of the citizens of the United States. The British merchants were restrained from pursuing it by the opposition of their East-India Company; the Russians were not admitted into Chinese ports; and few ships of any other nation were seen in that part of the ocean. The trade was prosecuted by men whose names are still distinguished among us as those of the master-spirits of American commerce,--the Thorndikes, the Perkinses, Lambs, Sturgis, Cushing, and others of Boston, Astor and others of New York. The greater number of the vessels sent from the United States were fine ships or brigs laden with valuable cargoes of West-India productions, British manufactured articles, and French, Italian, and Spanish wines and spirits; and the owners were men of large capital and high reputation in the commercial world, some of whom were able to compete with the British companies, and even to control their movements.
