The Cryptogram / Manaos
THE TOWN of Manaos is in 3° 8' 4" south latitude, and 67° 27' west longitude, reckoning from the Paris meridian. It is some four hundred and twenty leagues from Belem, and about ten miles from the _embouchure_ of the Rio Negro.

Manaos is not built on the Amazon. It is on the left bank of the Rio Negro, the most important and remarkable of all the tributaries of the great artery of Brazil, that the capital of the province, with its picturesque group of private houses and public buildings, towers above the surrounding plain.

The Rio Negro, which was discovered by the Spaniard Favella in 1645, rises in the very heart of the province of Popayan, on the flanks of the mountains which separate Brazil from New Grenada, and it communicates with the Orinoco by two of its affluents, the Pimichin and the Cassiquary.

After a noble course of some seventeen hundred miles it mingles its cloudy waters with those of the Amazon through a mouth eleven hundred feet wide, but such is its vigorous influx that many a mile has to be completed before those waters lose their distinctive character. Hereabouts the ends of both its banks trend off and form a huge bay fifteen leagues across, extending to the islands of Anavilhanas; and in one of its indentations the port of Manaos is situated. Vessels of all kinds are there collected in great numbers, some moored in the stream awaiting a favorable wind, others under repair up the numerous _iguarapes,_ or canals, which so capriciously intersect the town, and give it its slightly Dutch appearance.
