In 1802, this same Boston company sent the ship Globe, Magee, master, to the river.

During the year 1802, a brisk, and something like a permanent American trade appears to have been in contemplation by this Boston company. They sent the ship Caroline, Derby, master, from Boston, and the ship Manchester, Brice, master, from Philadelphia.

In 1803, Lamb & Company sent the ship Alert, Ebbets, master; also the ship Vancouver, Brown, master. This year, the ship Juno, Kendricks, master, from Bristol, Rhode Island, owned by De Wolf, entered the Columbia River for trade.

In the year 1804, Theodore Lyman sent the ship Guatimozin, Bumsted, master, from Boston. The Perkins Company sent the ship Hazard, Swift, master, to the river the same year.

In 1805, Lyman & Company sent the ship Atahualpa, O. Potter, master, from Boston. Lamb & Company sent the ship Caroline, Sturges, master, from the same place.

On the 15th of November, 1805, Lewis and Clarke, with their party, having crossed the Rocky Mountains under the direction of President Jefferson, of the United States, arrived at Cape Hancock; remaining but a few days, they crossed the Columbia River and encamped near the mouth of a small river still bearing the name of these two explorers. They left their encampment in March, 1806, and returned across the continent and reported the result of their expedition to the government.

This expedition consisted of one hundred and eighty soldiers or enlisted men. On arriving at the Mandan Village, on the Missouri River, in 1804, they encountered the influence of the Northwest British Fur Company, who, on learning their object, at once made arrangements to follow and get possession of the country at the mouth of the Columbia River.

In 1806, soon after Lewis and Clarke left their encampment on their return to the United States, the ship Vancouver, Brown, master, entered the river, having been sent out by Thomas Lyman, of Boston, in expectation of meeting Lewis and Clarke’s party at the mouth of the river. The Lamb Company sent the ship Pearl the same year, under the command of Captain Ebbets. Lyman, in addition to the Vancouver, sent the brig Lydia, Hill, master, to the river, making three American ships from Boston in the year 1806.

In 1807, the ship Hamilton arrived in the river, sent by Thomas Lyman, of Boston, L. Peters, master. The Perkins Company sent the Hazard, Smith, master.

In 1808, the ship Derby, Swift, master, sent by the Perkins Company. Lyman sent the ship Guatimozin, Glanville, master; both made successful trips in and out of the river.
