The Cerro Carriche is another granite mass similar to Yapacana, but not quite so high. It stands on the south bank of the river, between the mouths of two small rivers called Carriche and Trocoapure.
Early on February 21 we had the first distinct view of the Cerro Duida, looming, faintly outlined, in the distance. From afar it resembled a high, level plain, but as the vapor clinging to the huge, dark mass slowly dissolved itself, a well-defined short range appeared with twin peaks showing high above the rest of the mountains.
The Orinoco steadily decreases in width until the distance across is not more than half a mile; in many places the banks are high and composed of pink and white clay streaked with layers of dark-blue clay. On both sides the jungle presents an unbroken wall of tangled verdure; occasionally a slender palm rears its delicate head high above the riotous mass, as if gasping for one more breath of air before being strangled by the figs and creepers slowly entwining its stem with their death-dealing tentacles. Among the lower growth are vast areas of palms, known as coco del mono, with long fronds resembling those of the Seaforthia, and bearing small, hard nuts; the leaves are used in thatching huts and the carroza or covering of the boats. Another palm, tall and thorny, resembles the well-known chonta of Colombia; it bears large clusters of red nuts, which are very palatable when thoroughly boiled.
The heat was always intense and most oppressive; even the cool nights brought no respite, and in the early morning a thick vapor slowly rose from the water, to be later wafted above the tree-tops and disappear.
Flocks of hoatzins, or lizard-birds (Opisthocomus cristatus), were seen almost daily. They fussed and fluttered among the dense vegetation, but could not be induced to leave their dark retreat. There were also nesting-trees of the black and yellow orioles, better known as caciques, which are about the size of a blue jay; sometimes a single tree contained thirty or more nests placed close together, and also invariably a number of large wasp-nests were placed in the same tree. The nests of these birds differed from those of the giant orioles (Ostinops) in being smaller and having the opening at the top instead of at the side of the swinging bag.

At the end of the twentieth day we reached the mouth of the Cunucunuma, and camped upon its sandy banks for the night. This river is approximately five hundred feet wide at its mouth, shallow, with dark, clear water, and flows southward, joining the Orinoco at right angles, as the course of the latter river at this point is eastward; a low, forested hill called Ventana rises to the north. One may cover the distance from the mouth of the Cunucunuma to the Cassiquiare in a day, and reach the plains on which was located Esmeraldas by continuing his journey an additional day.
Not far above the mouth of the river is the dry bed of a stream, said to have been the former course of the Cunucunuma; short, soft grass now covers the ancient, sandy route and the lines of trees on each side present such clean-cut edges as to suggest well-kept hedgerows. Tapirs and capybaras have worn many paths through the luxuriant sward; apparently these animals come out into the open at night to feed.
The current of the river is so strong that we could not average more than four or five miles a day. Through the clear water we could see shoals of fish and numbers of large sting-rays darting about over the bottom. One fish, resembling a beautifully spotted trout, rose eagerly to a trailing hook baited with a strip of white cloth; it weighed about a pound, and was called pabón by the natives; on two occasions members of this species leaped clear of the water and into the boat as we poled along after nightfall. Another kind greatly resembled a flying-fish, and leaving the water singly or in pairs, skimmed over the surface for a distance of twenty yards or more, and then dropped with a splash; when “flying” it left a train of ripples in its wake, as if long appendages were trailing after it.
