A Brazilian port at the mouth of the Guama, on the E. shore of the Pará estuary, is a compact, regularly-built, thriving town, with whitewashed buildings, blue and white tiled roofs, tree-shaded streets, tram-cars, telephones, theatre, and cathedral; it is the emporium of the Amazon trade, exporting india-rubber and cacao, and sending foreign goods into the interior; though hot, it is healthy.
