With the introduction of steam vessels, which is now rapidly taking place, the trade of Manaos is destined to increase enormously. Woods used in building and furniture work, cocoa, caoutchouc, coffee, sarsaparilla, sugar-canes, indigo, muscado nuts, salt fish, turtle butter, and other commodities, are brought here from all parts, down the innumerable streams into the Rio Negro from the west and north, into the Madeira from the west and south, and then into the Amazon, and by it away eastward to the coast of the Atlantic.

Manaos was formerly called Moura, or Barra de Rio Negro. From 1757 to 1804 it was only part of the captaincy which bears the name of the great river at whose mouth it is placed; but since 1826 it has been the capital of the large province of Amazones, borrowing its latest name from an Indian tribe which formerly existed in these parts of equatorial America.

Careless travelers have frequently confounded it with the famous Manoa, a city of romance, built, it was reported, near the legendary lake of Parima--which would seem to be merely the Upper Branco, a tributary of the Rio Negro. Here was the Empire of El Dorado, whose monarch, if we are to believe the fables of the district, was every morning covered with powder of gold, there being so much of the precious metal abounding in this privileged locality that it was swept up with the very dust of the streets. This assertion, however, when put to the test, was disproved, and with extreme regret, for the auriferous deposits which had deceived the greedy scrutiny of the gold-seekers turned out to be only worthless flakes of mica!
