SCENES ON THE AMAZON.
The chief feature of the Lower Amazon is the vast expanse of smooth water, of a pale yellowish-olive colour, bearing on its bosom detached ma.s.ses of aquatic gra.s.s floating down like islands, sometimes mixed with huge trees, their branches and roots interlocked, and often carrying among them wild animals, which, unconscious of their character, have there taken refuge from their foes, or have ventured thither in search of prey. The timid stag and fierce jaguar are sometimes thus entrapped and carried out to sea. At even and morn flocks of parrots and large and yellow macaws, fly backwards and forwards, uttering their wild and hoa.r.s.e cries; herons and rails frequent the marshes on its banks; while all night long the cries of gulls and terns are heard over the sandy banks where they deposit their eggs, while they may be seen during the day sitting in rows on floating logs gliding down the stream, motionless and silent, as if contemplating the scenery. There are divers and darters, too, in abundance. Now and then a huge manatee comes gliding by, its cow-like head rising to breathe the upper air; while dolphins, porpoise-like, rear their backs above the surface, or leap half out of the water as they swim up the stream. On the low banks, huge alligators with open jaws are basking in the sun, or leisurely swimming across the river.
THE RAINY SEASON.
This magnificent region enjoys a perpetual summer, its various fruits coming to maturity, according to their character, at different periods throughout the year. It has, however, its wet and dry seasons. The rain occurs at one time in the Upper Amazon, and at another in the Lower,--greatly swelling the volume of water in the main stream, which, unable to find its way towards the ocean, rushes through the countless channels and igarapes, overflowing the lower portions of a vast district called the Gapo. The waters begin to rise in February, and progress inch by inch until the middle of June, gradually swelling the rivers and lakes, when, these becoming filled, the lower lands and sand-banks are overflowed even far-away in the interior. The forests are traversed by numerous gullies, which in the dry season are wide dells, but now become transformed into broad creeks, through which canoes can proceed to great distances under the shade of the lofty trees.
At this period of the year the inland pools are frequented by swarms of turtle, as well as alligators, and shoals of fish which leave the main river; while the flocks of wading birds migrate northerly, thus greatly dispersing the food on which the natives depend for their existence.
The fishermen who have been employed during the dry months in catching turtle and fish on the sand-banks return to their villages, though some employ themselves in collecting the Brazil-nut and wild cacao, which are now ripe.
About the first week in June, the flood has risen sometimes to the height of forty feet above the usual level of the river, when it now begins to subside. The rains, however, do not fall continuously, though very heavy at times. Several days of beautiful sunny weather generally intervene. The fine season begins with a few days of brilliant weather--the rays of the sun breaking forth among the pa.s.sing clouds.
Towards the middle of July the sand-banks again appear, flocks of gulls and other water birds fly by, and the gaily-plumaged inhabitants of the forest come forth into full activity and life.
STORMS.
The navigation of the Amazon is not free from danger. Fierce storms arise; black clouds gather over the blue expanse, suffused anon with a lurid yellow tinge, and the fierce whirlwind howls along the river-banks, tearing the placid stream into ma.s.ses of foam; the tall trees bend before the blast, and huge branches are wrenched off and hurled into the water. The long-legged waders and other water birds, unable to face it, throw themselves on the ground, and cling with claws and beak to the sand to escape being carried helplessly away.
THE POROROCCA.
Sometimes, too, the destroying pororocca--a vast wave rising across the whole width of the stream, to the height of twelve or fifteen feet-- sweeps up the stream. Advancing noiselessly over the deeper portions of the river-bed, it rises into an angry billow, with a fearful roar when pa.s.sing over a shallow, or meeting any impediment in its course. A French traveller describes an island where he and his companions had rested on their voyage down the stream. They had happily gone over to the mainland on the previous evening, when, as they stood on the sh.o.r.e, the pororocca was heard approaching. Onward it came till the island was reached, when, with an angry roar, it burst into ma.s.ses of foam, and swept over the devoted spot, carrying in its fierce embrace not only the whole ma.s.s of vegetation, but overturning the foundations of the island itself, so that in a few seconds not a vestige remained. Sometimes, too, the higher banks of the Upper Amazon, crowned by lofty trees, are worn away by the rapid current, increased during the rainy season, continually pa.s.sing beneath them, till the upper portions, deprived of their support, fall over with a terrific roar into the stream, dragging with them their neighbours. The earth trembles with the concussion, the waters hiss and foam and rush furiously over the impediments in their course. Sometimes miles of the bank thus give way, the sound being heard far up and down the stream. Occasionally a canoe and its crew-- who, to avoid the current, have been toiling close along the bank--have been thus overwhelmed; while others, descending, unaware of the obstruction, have been dragged by the furious whirlpool thus formed amid the tangled branches, and destroyed.
PART THREE, CHAPTER FOUR.
CHARACTER OF VEGETATION ON THE BANKS.
A dense vegetation, though somewhat varied in character, rises like a lofty wall of verdure along the banks of the mighty stream, from the base of the Andes to its mouth in the Atlantic. There, where the influence of the sea-breeze is felt, the ever-present mangrove of the tropics forms a thick belt round the sh.o.r.es of its numberless islands.
Higher up, various palms of many graceful forms appear, interspersed with numberless other trees, some bearing huge pods a yard long, others vast nuts and other curious fruits,--the banks below fringed either with giant gra.s.ses and broad-leaved bananas, or here and there with the large wide heart-shaped leaves of the aninga growing on the summit of tall stems, or in other places with the murici of a lower growth close to the water"s edge. Among the most remarkable is the white-stemmed cecropia, the lofty ma.s.saranduba, or cow-tree, often rising to the height of one hundred and fifty feet; the seringa, or india-rubber tree, with its smooth grey bark, tall erect trunk, and thick glossy leaves. The a.s.sai-palm, with its slender stem, its graceful head and delicate green plumes, is at first more numerous than any other. Now appears the miriti, or mauritia--one of the most beautiful of its tribe, with pendent cl.u.s.ters of glossy fruit, and enormous spreading fan-like leaves cut into ribbons; the jupati, with plume-like leaves forty feet and upwards in length, graceful in the extreme, starting almost from the ground. Here is seen also the bussu, with stiff entire leaves, also of great length, growing upright from a short stem, close together, and serrated along their edges. Higher up still, while the palms become less numerous, other trees take their places. Among them appears conspicuous the majestic sumaumera, its flat dome rounded, but not conical, towering high above the forest. The branches of this tree are greatly ramified and knotty, and the bark is white. Conspicuous, too, is the taxi, with brown buds and white flowers; while the margin of the water is thickly fringed by a belt of arrow-gra.s.s, or _frexes_--so called by the Portuguese--six feet in height. Its name is given in consequence of being used by the Indians in making arrows for their blowpipes.
Amid this wonderful ma.s.s of forest vegetation grows an intricate tracery of lianas and climbing sipos, some running round and round the trees, and holding them in a close embrace; others hanging from branch to branch in rich festoons, covered with starlike flowers, or dropping in long lines to the ground,--often to take root and shoot upwards again round a neighbouring stem, or drooping like the loose cordage of a ship swinging in the breeze. Often they form so dense and impenetrable a thicket from the ground upwards that a way must be cleared with an axe to proceed even a short distance from the banks towards the inner recesses of the forest.
THE GAPO.
On the Gapo, or submerged lands, however, a considerable difference in the vegetation appears. The palms are here often more numerous than in other parts. This is the region where the cacao-tree and p.r.i.c.kly sarsaparilla grow. Here the underwood is less dense, the sipos retiring to weave their tracery among the upper branches alone. Though during the dry season the vegetation springs up with wonderful rapidity, it is swept away by the next overflow.
Here the lovely orchis tribe adorn the gloomy shades with their brilliant flowers. Among the most beautiful is the oncidium, of a yellow hue, often seen--apparently suspended in air between the stems of two trees--shining in the gloom, as if its petals were of gold. In reality it grows at the end of a wire-like stalk a yard and a half long, springing from a cl.u.s.ter of thick leaves on the bark of a tree; others have white and spotted blossoms, growing sometimes on rotten logs floating on the water, or on moss and decayed bark just above it. Still more magnificent is the Flor de Santa Ana, of a brilliant purple colour, emitting a most delicious odour.
Peculiar and strange is this region of the Gapo. When the waters are at their height it can be traversed in all directions. The trees which grow on it, and the animals which here have their abodes, appear to differ from those of other districts.
Let us accompany the naturalist Wallace, in his canoe, through a district of this description; now forcing our way under branches and among dense bushes, till we get into a part where the trees are loftier and a deep gloom prevails. Here the lowest branches of the trees are level with the surface of the water, many of them putting forth flowers.
As we proceed we sometimes come to a grove of small palms, the leaves being now only a few feet above us. Among them is the maraja, bearing bunches of agreeable fruit, which, as we pa.s.s, the Indians cut off with their long knives. Sometimes the rustling of leaves overhead tells us that monkeys are near, and we soon see them peeping down from among the thick foliage, and then bounding rapidly away. Presently we come out into the sunshine, on a lake filled with lilies and beautiful water-plants, little bladder-worts, and the bright blue flowers and curious leaves with swollen stalks of the pontederias. Again we are in the gloom of the forest, among the lofty cylindrical trunks rising like columns out of the deep water; and now there is a splash of fruit falling around us, announcing that birds are feeding overhead, and we discover a flock of parrakeets, or bright blue chatterers, or the lovely pompadour, with its delicate white wings and claret-coloured plumage.
Now, with a whir, a trogon on the wing seizes the fruit, or some clumsy toucan makes the branches shake as he alights above our heads.
This region, as might be supposed, is not dest.i.tute of inhabitants.
Several tribes of Indians dwell within it all the year round. Among them are the Purupurus and Muras tribes, who, spending most of their time in their canoes, in the dry season build small huts on its sandy sh.o.r.es; and when the waters overflow it, form rafts, which they secure between the trees, sleeping in rude huts suspended from the stems over the deep water, and lighting their fires on ma.s.ses of mud placed on their floating homes. They subsist entirely on fish, turtle, and manatee.
Several species of trogons are peculiar to this submerged region. The curious black umbrella-bird is entirely confined to it, as is also the little bristle-tailed manakin. Several monkeys visit it during the wet season, for the sake of its peculiar fruits; and here the scarlet-faced urikari has its home.
For miles and miles together the native traverses this region in his canoe, pa.s.sing through small streams, lakes, and swamps, sc.r.a.ping the tree trunks, and stooping to pa.s.s between the leaves of the p.r.i.c.kly palms, now level with the water--though raised on stems forty feet high--while everywhere round him stretches out an illimitable waste of waters, but all covered with the lofty virgin forest. In this trackless maze, by slight indications of broken twigs or sc.r.a.ped bark, he finds his way with unerring certainty.
"This curious region," says Wallace, "extends from a little above Santarem to the confines of Peru, a distance of about 1700 miles; and varies in width on each side of the river from one to ten or twenty miles."
TRIP UP AN IGARAPE INTO THE INTERIOR.
Let us leave the mighty stream, and wander amidst the picturesque windings of an igarape, into the depths of the forest, with Professor Aga.s.siz. Pa.s.sing into its narrow entrance, the lofty trees arching overhead shelter the voyager in his light canoe from the glaring heat of the noonday sun. The air is cool and refreshing. Not a ripple stirs the water, save that caused by the paddles of the Indian crew. Clumps of the light and exquisitely graceful a.s.sai-palm shoot up everywhere on either side from the denser forest. Here and there the drooping bamboo dips its feathery branches into the water, covered sometimes to their very tips with the purple of convolvuli; yellow bignonias carry their golden cl.u.s.ters to the very summits of some of the more lofty trees; while white-flowering myrtles and orange-coloured mallows border the stream. Life abounds in this quiet retreat. Birds and b.u.t.terflies are numerous on the margin of the water. Crabs of every variety of colour and size sit on the trunks of decaying logs, watching for their prey,-- to make their escape, however, with nimble feet, when pursued.
Or let us start before daylight, on a calm morning, along the banks of a larger tributary, to proceed towards the heights of the Sierra Erere.
As dawn begins to redden the sky, large flocks of ducks and of a small Amazonian goose may be seen flying towards the lake. Here and there we see a cormorant, seated alone on the branch of a dead tree; or a kingfisher poises himself over the water, watching for his prey.
Numerous gulls are gathered in large companies on the trees along the river-sh.o.r.e. Alligators lie on its surface, diving with a sudden splash at the approach of the canoe. Occasionally a porpoise emerges from the water, showing himself for a moment, and then disappearing. Sometimes a herd of capybaras, resting on the water"s edge, are startled at our approach.
There sits, on the branch of an imbauba, rolled-up in its peculiar att.i.tude, a sloth, the very picture of indolence, with its head sunk between its arms. The banks, covered in many places with the beautiful capim-gra.s.s, afford excellent pasturage for cattle.
Now we turn into an inner stream, or igarape, often having to make our way with difficulty amid islands of capim-gra.s.s. Now we pa.s.s through a magnificent forest of the beautiful fan-palm--the miriti--overshadowing many smaller trees and innumerable shrubs, bearing light conspicuous flowers. Among them are numerous Leguminosae--one of the most striking, the fava, having a colossal pod.
The whole ma.s.s of vegetation is interwoven with innumerable creepers, amid which the flowers of the bignonia, with their open trumpet-shaped corollas, are conspicuous. The capim is bright with the blossoms of the mallow growing in its midst, in some places edged with the broad-leaved aninga--a large aquatic arum. Through these forests, where animal life is no less rich and varied than the vegetation, our canoe glides silently for hours.
The sedgy gra.s.ses on either side are full of water birds. One of the most common is a small chestnut-brown wading bird--the jacana--whose toes are immensely long in proportion to its size, enabling it to run over the surface of the aquatic vegetation as if it were solid ground.
It is their breeding season--January. At every turn of the boat we start them up--usually in pairs. Their flat, open nests generally contain five flesh-coloured eggs, streaked in zig-zag with dark brown lines. Among the other waders are a snow-white heron, another ash-coloured, and a large white stork. The ash-coloured herons are always in pairs--the white always singly, standing quiet and alone on the edge of the water, or half hidden in the green capim. The trees and bushes are full of small warbler-like birds. The most numerous and interesting is one which builds a very extraordinary nest, considering the size of the bird. It is known among the country people by the name of _pedreiro_, or the _forneiro_--both names referring to the nature of its habitation. This singular nest is built of clay, and is as hard as stone--_pedra_; while it is the shape of the mandioca oven--_forno_--in which the country people prepare their farina. It is about a foot in diameter, and stands edgewise upon the branch or crotch of a tree.
Among the smaller birds are bright tanagers, and a species resembling the canary. Humming-birds are scarce, though here and there a few appear; while countless numbers of parrots and parrakeets fly overhead in dense crowds, at times drowning every other sound with their noisy clatter.
Birds of prey are not wanting. Among them is the red hawk, about the size of a kite--and so tame, that even when a canoe pa.s.ses under the branch on which he is sitting, he does not fly away.
Among the most striking are the gallinaceous birds. The commonest is the cigana, to be seen in groups of fifteen or twenty perched on trees overhanging the water, and feeding upon berries. At night they roost in pairs; but in the daytime are always in larger companies. In appearance they have something of the character of both the pheasant and peac.o.c.k, and yet do not closely resemble either. With the exception of some small partridge-like gallinaceous birds, the representatives of this family in Brazil belong to types which do not exist in any other parts of the world. Here the cura.s.sow, the jacu, the jacami, and the unicorn resemble as much the bustard and other ostrich-like birds as the hen and pheasant.
The most numerous insects to be met with are dragonflies; some with crimson bodies, black heads, and burnished wings; others with large, green bodies, crossed by blue bands.
THE CAMPOS.
Although the forests cover generally the whole length and breadth of the Amazonian Valley, there are here and there, on the higher ground, open dry plains with scanty vegetation,--the ground in the water-courses or gullies, formed of clay, being baked by the heat of the sun into slate-like ma.s.ses. One of these spots we now reach. The most prominent plants of this sandy or clayey region are cl.u.s.ters of cacti and curua palms--a kind of stemless, low palm, with broad leaves springing, vase-like, from the ground. Here also grow wild pineapples; and in broad sunlight numerous humming-birds delight to sport and feed upon the blossoms of the various plants which find no room to bloom in the darker shades of the forest.
GEOLOGY OF THE AMAZONIAN VALLEY.
Professor Aga.s.siz remarks that no formation--known to geologists-- resembling that of the Amazon exists on the face of the earth. Its extent is stupendous. It stretches from the Atlantic sh.o.r.e through the whole width of Brazil into Peru, to the very foot of the Andes--one vast extent of red sandstone, capped by a yellow-ochred clay; not only along the banks of the main river, but forming the sides of those of its tributaries, to their far-off sources, probably over the whole basin of the Paraguay and the Rio de la Plata. How are these vast deposits formed? is the question. The easiest answer, he observes, and the one which most readily suggests itself, is that of a submersion of the continent at successive periods--to allow the acc.u.mulation of these materials--and its subsequent elevation. This explanation is rejected, for the simple reason that the deposits show no signs whatever of a marine origin. No sea-sh.e.l.ls, or remains of any marine animal, have as yet been found throughout their whole extent--over a region several thousands of miles in length, and from five to seven hundred miles in width. It is evident, he considers, that this basin was a fresh-water basin, these deposits fresh-water deposits. It is true that calcareous layers thickly studded with sh.e.l.ls have been found interspersed with the clay; but though supposed to be marine fossils, he recognised them for what they really are--fresh-water sh.e.l.ls of the family of the Naiades.
As their resemblance is very remarkable, the mistake as to their true zoological character is natural: indeed, many travellers have confounded some fresh-water fishes from the Upper Amazon of the genus of Pterophyllum with the marine genus Platax. He considers that the immense glacier which probably existed at the same time that ice, thousands of feet thick, covered the centre of Europe, must have been formed in this valley, and then, ploughing its bottom over and over again, and grinding all the materials beneath it into a fine powder, must ultimately have forced its way through the colossal sea-wall which it had built up eastward into the Atlantic.
A DAY AND NIGHT ON THE AMAZON, WITH THEIR SIGHTS AND SOUNDS.
Day is beginning to dawn, the birds are astir, the cicada have begun their music; flocks of parrots and macaws, and other winged inhabitants of the forest, pa.s.s by in numbers, seeking their morning repast; beautiful long-tailed and gilded moths like b.u.t.terflies fly over the tree-tops. Rapid is the change from the dark night. The sky in the east a.s.sumes suddenly the loveliest azure colour, across which streaks of thin white clouds are painted. The varied forms of the numberless trees, imperceptible during the gloom of night, now appear, the smaller foliage contrasting with the large glossy leaves of the taller trees, or the feathery, fan-shaped fronds of palms. For a time the fresh breeze blows, but flags under the increasing power of the sun, and finally dies away, the heat and electric tension of the atmosphere becoming almost insupportable.
The heat increases as the day draws on. Languor and uneasiness seize on every one;--even the denizens of the forest betray it by their motions.
By this time every voice of bird or mammal is hushed. Only in the trees is heard at intervals the whir of the cicada. The leaves, so soft and fresh in the early morn, now become lax and drooping. The flowers shut their petals. The natives, returning to their huts, fall asleep in their hammocks, or, seated on mats in the shade appear too languid even to talk. White clouds now appear in the east, and gather into c.u.muli, with an increasing blackness along their lower portions. The whole eastern horizon becomes rapidly black, the dark hue spreading upwards.
Even the sun is at length obscured. Then the rush of a mighty wind is heard through the forest swaying the tree-tops. A vivid flash of lightning bursts forth, then a crash of thunder, and down streams the deluging rain. The storm soon ceases, leaving the bluish-black motionless clouds in the sky till night. Meantime all nature is refreshed, but heaps of flower petals and leaves are seen under the trees.
Towards evening life revives again. The noises of the forest animals begin just as the sun sinks behind the trees, leaving the sky above of the intensest shade of blue. The briefest possible twilight commences, and the sounds of multifarious life come from every quarter. Troops of howling monkeys, from their lofty habitations among the topmost branches--some near, some at a distance--fill the echoing forest with their dismal noise; flocks of parrots and blue macaws pa.s.s overhead, the different kinds of cawing and screaming of the various species making a terrible discord. Added to them are the calls of strange cicada--one large kind perched high on the trees setting up a most piercing chirp.
It begins with the usual harsh jarring tone of its tribe, rapidly becoming shriller, until it ends in a long and loud note resembling the steam whistle of a locomotive engine. A few of these wonderful performers make a considerable item in the evening concert. The uproar of beasts, birds, and insects lasts but a short time; the sky quickly loses its intense hue, and the night sets in. Then begin the tree-frogs--Quack, quack! Drum, drum! Hoo, hoo! These, accompanied by melancholy night-jars, keep up their monotonous cries till late at night.
The night, however, is not given over to darkness. In every forest path, across the calm waters of the igarapes, along open s.p.a.ces, in the village as well as in spots remote from man"s abode, the whole air is full of bright and glittering lights of varied hue; now darting here, now there, like meteors flashing through the sky--now for a moment obscured, to burst forth again with greater brilliancy. Beautiful as is the English glow-worm, the fire-flies and fire-beetles, the elaters of the tropics, far surpa.s.s them in brilliancy. Their light is redder and more candle-like, and being alternately emitted and concealed, each of the tiny vermilion flames performing its part in the aerial mazy dance, the spectacle is singularly beautiful. In the marshy districts is seen the large elater, which displays both red and green lights; the red glare, like that of a lamp, alternately flashing on the beholder, then concealed as the insect turns his body in flight, but the ruddy reflection on the gra.s.s beneath being constantly visible as it leisurely pursues its course. Now and then a green light is displayed, and then the mingling of the two complementary colours, red and green, in the evolutions of flight, surpa.s.ses description. Even the brilliant elaters, however, will scarcely enable the traveller to find his way amid the darkness through the forest.
