As early as 1763, shortly after the acquisition of the Canadas by Great Britain, Captain Jonathan Carver, who had been in the British provincial army, projected a journey across the continent between the forty-third and forty-sixth degrees of northern latitude to the shores of -the Pacific Ocean. His objects were to ascertain the breadth of the continent at its broadest part, and to determine on some place on the shores of the Pacific, where government might establish a post to facilitate the discovery of a northwest passage, or a communication between Hudson's Bay and the Pacific Ocean. This place he presumed would be somewhere about the Straits of Annian, at which point he supposed the Oregon disembogued itself. It was his opinion, also, that a settlement on this extremity of America would disclose new sources of trade, promote many useful discoveries, and open a more direct communication with China and the English settlements in the East Indies, than that by the Cape of Good Hope or the Straits of Magellan. * This enterprising and intrepid traveller was twice baffled in individual efforts to accomplish this great journey. In 1774, he was joined in the scheme by Richard Whitworth, a member of Parliament, and a man of wealth. Their enterprise was projected on a broad and bold plan. They were to take with them fifty or sixty men, artificers and mariners. With these they were to make their way up one of the branches of the Missouri, explore the mountains for the source of the Oregon, or River of the West, and sail down that river to its supposed exit, near the Straits of Annian. Here they were to erect a fort, and build the vessels necessary to carry their discoveries by sea into effect. Their plan had the sanction of the British government, and grants and other requisites were nearly completed, when the breaking out of the American Revolution once more defeated the undertaking. **The expedition of Sir Alexander Mackenzie in 1793, across the continent to the Pacific Ocean, which he reached in lat. 52 20'

48", again suggested the possibility of linking together the trade of both sides of the continent. In lat. 52 30' he had descended a river for some distance which flowed towards the south, and wag called by the natives Tacoutche Tesse, and which he erroneously supposed to be the Columbia. It was afterwards ascertained that it emptied itself in lat. 49 degrees, whereas the mouth of the Columbia is about three degrees further south.

When Mackenzie some years subsequently published an account of his expeditions, he suggested the policy of opening an intercourse between the Atlantic and Pacific oceans, and forming regular establishments through the interior and at both extremes, as well as along the coasts and islands. By this means, he observed, the entire command of the fur trade of North America might be obtained from lat. 48 north to the pole, excepting that portion held by the Russians, for as to the American adventurers who had hitherto enjoyed the traffic along the northwest coast, they would instantly disappear, he added, before a well regulated trade.

A scheme of this kind, however, was too vast and hazardous for individual enterprise; it could only be undertaken by a company under the sanction and protection of a government; and as there might be a clashing of claims between the Hudson's Bay and Northwest Company, the one holding by right of charter, the other by right of possession, he proposed that the two comparties should coalesce in this great undertaking. The long-cherished jealousies of these two companies, however, were too deep and strong to allow them to listen to such counsel.

In the meantime the attention of the American government was attracted to the subject, and the memorable expedition under Messrs. Lewis and Clarke fitted out. These gentlemen, in 1804, accomplished the enterprise which had been projected by Carver and Whitworth in 1774. They ascended the Missouri, passed through the stupendous gates of the Rocky Mountains, hitherto unknown to white men; discovered and explored the upper waters of the Columbia, and followed that river down to its mouth, where their countryman, Gray, had anchored about twelve years previously.

Here they passed the winter, and returned across the mountains in the following spring. The reports published by them of their expedition demonstrated the practicability of establishing a line of communication across the continent, from the Atlantic to the Pacific Ocean.

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.
