It was then that the idea presented itself to the mind of Mr. Astor, of grasping with his individual hand this great enterprise, which for years had been dubiously yet desirously contemplated by powerful associations and maternal governments.  For some time he revolved the idea in his mind, gradually extending and maturing his plans as his means of executing them augmented.  The main feature of his scheme was to establish a line of trading posts along the Missouri and the Columbia, to the mouth of the latter, where was to be founded the chief trading house or mart.  Inferior posts would be established in the interior, and on all the tributary streams of the Columbia, to trade with the Indians; these posts would draw their supplies from the main establishment, and bring to it the peltries they collected.  Coasting craft would be built and fitted out, also at the mouth of the Columbia, to trade, at favorable seasons, all along the northwest coast, and return, with the proceeds of their voyages, to this place of deposit.  Thus all the Indian trade, both of the interior and the coast, would converge to this point, and thence derive its sustenance.

A ship was to be sent annually from New York to this main establishment with reinforcements and supplies, and with merchandise suited to the trade.  It would take on board the furs collected during the preceding year, carry them to Canton, invest the proceeds in the rich merchandise of China, and return thus freighted to New York.  As, in extending the American trade along the coast to the northward, it might be brought into the vicinity of the Russian Fur Company, and produce a hostile rivalry, it was part of the plan of Mr. Astor to conciliate the good-will of that company by the most amicable and beneficial arrangements.  The Russian establishment was chiefly dependent for its supplies upon transient trading vessels from the United States.  These vessels, however, were often of more harm than advantage.  Being owned by private adventurers, or casual voyagers, who cared only for present profit, and had no interest in the permanent prosperity of the trade, they were reckless in their dealings with the natives, and made no scruple of supplying them with fire-arms.  In this way several fierce tribes in the vicinity of the Russian posts, or within the range of their trading excursions, were furnished with deadly means of warfare, and rendered troublesome and dangerous neighbors.

The Russian government had made representations to that of the United States of these malpractices on the part of its citizens, and urged to have this traffic in arms prohibited; but, as it did not infringe any municipal law, our government could not interfere.  Yet, still it regarded, with solicitude, a traffic which, if persisted in, might give offence to Russia, at that time almost the only friendly power to us.  In this dilemma the government had applied to Mr. Astor, as one conversant in this branch of trade, for information that might point out a way to remedy the evil.  This circumstance had suggested to him the idea of supplying the Russian establishment regularly by means of the annual ship that should visit the settlement at the mouth of the Columbia (or Oregon); by this means the casual trading vessels would be excluded from those parts of the coast where their malpractices were so injurious to the Russians.
