On the morrow, the 7th of June, the jangada breasted the banks of the
village of Pucalppa, named also New Oran. Old Oran, situated fifteen
leagues down stream on the same left bank of the river, is almost

Indians belonging to the Mayoruna and Orejone tribes. Nothing can be
more picturesque than this village with its ruddy-colored banks, its
unfinished church, its cottages, whose chimneys are hidden amid the
palms, and its two or three ubas half-stranded on the shore.

During the whole of the 7th of June the jangada continued to follow
the left bank of the river, passing several unknown tributaries of no

easterly shore of the island of Sinicure; but the pilot, well served
by the crew, warded off the danger and remained in the flow of the
stream.

In the evening they arrived alongside a narrow island, called Napo
Island, from the name of the river which here comes in from the
north-northwest, and mingles its waters with those of the Amazon

streams before falling into the Amazon.

Several years later a French traveler, Paul Marcoy, went out to
examine the color of the waters of this tributary, which has been
graphically compared to the cloudy greenish opal of absinthe. At the
