The violence of the wind abated in the course of an hour, but the deluge of rain continued until about three o'clock in the morning; the sky was lighted up by almost incessant flashes of pallid lightning, and the thunder pealing from side to side without interruption.Our clothing, hammocks, and goods were thoroughly soaked by the streams of water which trickled through between the planks.In the morning all was quiet, but an opaque, leaden mass of clouds overspread the sky, throwing a gloom over the wild landscape that had a most dispiriting effect.These squalls from the west are always expected about the time of the breaking up of the dry season in these central parts of the Lower Amazons.They generally take place about the beginning of February, so that this year they had commenced much earlier than usual.The soil and climate are much drier in this part of the country than in the region lying farther to the west, where the denser forests and more clayey, humid soil produce a considerably cooler atmosphere.The storms may be, therefore, attributed to the rush of cold moist air from up river, when the regular trade-wind coming from the sea has slackened or ceased to blow.
On the 26th we arrived at a large sand bank connected with an island in mid-river, in front of an inlet called Maraca-uassu.
Here we anchored and spent half a day ashore.Penna's object in stopping was simply to enjoy a ramble on the sands with the children, and give Senora Katita an opportunity to wash the linen.The sandbank was now fast going under water with the rise of the river; in the middle of the dry season it is about a mile long and half a mile in width.The canoe-men delight in these open spaces, which are a great relief to the monotony of the forest that clothes the land in every other part of the river.
Farther westward they are much more frequent, and of larger extent.They lie generally at the upper end of islands; in fact, the latter originate in accretions of vegetable matter formed by plants and trees growing on a shoal.The island was wooded chiefly with the trumpet tree (Cecropia peltata), which has a hollow stem and smooth pale bark.The leaves are similar in shape to those of the horse-chestnut, but immensely larger; beneath they are white, and when the welcome trade-wind blows they show their silvery undersides--a pleasant signal to the weary canoe traveller.The mode of growth of this tree is curious: the branches are emitted at nearly right angles with the stem, the branchlets in minor whorls around these, and so forth, the leaves growing at their extremities, so that the total appearance is that of a huge candelabrum.Cecropiae of different species are characteristic of Brazilian forest scenery; the kind of which Iam speaking grows in great numbers everywhere on the banks of the Amazons where the land is low.In the same places the curious Monguba tree (Bombax ceiba) is also plentiful; the dark green bark of its huge tapering trunk, scored with grey, forming a conspicuous object.The principal palm tree on the lowlands is the Jauari (Astrvocaryum Jauari), whose stem, surrounded by whorls of spines, shoots up to a great height.On the borders of the island were large tracts of arrow-grass (Gynerium saccharoides), which bears elegant plumes of flowers, like those of the reed, and grows to a height of twenty feet, the leaves arranged in a fan-shaped figure near the middle of the stem.Iwas surprised to find on the higher parts of the sandbank the familiar foliage of a willow (Salix Humboldtiana).It is a dwarf species, and grows in patches resembling beds of osiers; as in the English willows, the leaves were peopled by small chrysomelideous beetles.
In wandering about, many features reminded me of the seashore.
Flocks of white gulls were flying overhead, uttering their well-known cry, and sandpipers coursed along the edge of the water.
Here and there lonely wading-birds were stalking about; one of these, the Curiaca (Ibis melanopis), flew up with a low cackling noise, and was soon joined by a unicorn bird (Palamedea cornuta), which I startled up from amidst the bushes, whose harsh screams, resembling the bray of a jackass, but shriller, disturbed unpleasantly the solitude of the place.Amongst the willow bushes were flocks of a handsome bird belonging to the Icteridae or troupial family, adorned with a rich plumage of black and saffron-yellow.I spent some time watching an assemblage of a species of bird called by the natives Tumburi-para, on the Cecropia trees.It is the Monasa nigrifrons of ornithologists, and has a plain slate-coloured plumage with the beak of an orange hue.It belongs to the family of Barbets, most of whose members are remarkable for their dull, inactive temperament.Those species which are arranged by ornithologists under the genus Bucco are called by the Indians, in the Tupi language, Tai-assu uira, or pig-birds.They remain seated sometimes for hours together on low branches in the shade, and are stimulated to exertion only when attracted by passing insects.This flock of Tamburi-para were the reverse of dull; they were gambolling and chasing each other amongst the branches.As they sported about, each emitted a few short tuneful notes, which altogether produced a ringing, musical chorus that quite surprised me.
