In many parts of my Journal, I have expressed an opinion that travellers have exaggerated the beauty and brilliancy of tropical vegetation, and on a calm review of all I have seen in the districts I have visited, I must repeat it.

There is a grandeur and solemnity in the tropical forest, but little of beauty or brilliancy of colour. The huge buttress trees, the fissured trunks, the extraordinary air roots, the twisted and wrinkled climbers, and the elegant palms, are what strike the attention and fill the mind with admiration and surprise and awe. But all is gloomy and solemn, and one feels a relief on again seeing the blue sky, and feeling the scorching rays of the sun.

It is on the roadside and on the rivers' banks that we see all the beauty of the tropical vegetation. There we find a mass of bushes and shrubs and trees of every height, rising over one another, all exposed to the bright light and the fresh air; and putting forth, within reach, their flowers and fruit, which, in the forest, only grow far up on the topmost branches. Bright flowers and green foliage combine their charms, and climbers with their flowery festoons cover over the bare and decaying stems. Yet, pick out the loveliest spots, where the most gorgeous flowers of the tropics expand their glowing petals, and for every scene of this kind, we may find another at home of equal beauty, and with an equal amount of brilliant colour.

Look at a field of buttercups and daisies,—a hill-side covered with gorse and broom,—a mountain rich with purple heather,—or a forest-glade, azure with a carpet of wild hyacinths, and they will bear a comparison with any scene the tropics can produce. I have never seen anything more glorious than an old crab-tree in full blossom; and the horse-chesnut, lilac, and laburnum will vie with the choicest tropical trees and shrubs. In the tropical waters are no more beautiful plants than our white and yellow water-lilies, our irises, and flowering rush; for I cannot consider the flower of the Victoria regia more beautiful than that of the Nymphæa alba, though it may be larger; nor is it so abundant an ornament of the tropical waters as the latter is of ours.

But the question is not to be decided by a comparison of individual plants, or the effects they may produce in the landscape, but on the frequency with which they occur, and the proportion the brilliantly coloured bear to the inconspicuous plants. My friend Mr. R. Spruce, now investigating the botany of the Amazon and Rio Negro, assures me that by far the greater proportion of plants gathered by him have inconspicuous green or white flowers; and with regard to the frequency of their occurrence, it was not an uncommon thing for me to pass days travelling up the rivers, without seeing any striking flowering tree or shrub. This is partly owing to the flowers of most tropical trees being quickly deciduous: they no sooner open, than they begin to fall; the Melastomas in particular, generally burst into flower in the morning, and the next day are withered, and for twelve months the tree bears no more flowers. This will serve to explain why the tropical flowering trees and shrubs do not make so much show as might be expected.

From the accounts of eye-witnesses, I believe that the forests of the southern United States present a more gay and brilliant appearance than those of tropical America.

Humboldt, in his "Aspects of Nature," repeatedly remarks on the contrast between the steppes of Tartary and the llanos of the Orinooko. The former, in the temperate zone, are gay with the most brilliant flowers; while the latter, in the tropics, produce little but grasses and sedges, and only few and inconspicuous flowering plants. Mr. Darwin mentions the brilliancy of the flowers adorning the plains of Monte Video, which, with the luxuriant thistles of the Pampas, seems hardly equalled in the campos of tropical Brazil, where, with some exceptions, the earth is brown and sterile. The countless beautiful geraniums and heaths of the Cape cease on entering the tropics, and we have no account of any plants equally striking and brilliant supplying their place.

What we may fairly allow of tropical vegetation is, that there is a much greater number of species, and a greater variety of forms, than in the temperate zones. Among this great variety occur, as we might reasonably expect, the most striking and brilliant flowers, and the most remarkable forms of stem and foliage. But there is no evidence to show that the proportion of species bearing brightly coloured, compared to those bearing inconspicuous flowers, is any greater in the tropics than in the temperate regions; and with regard to individuals—which is, after all, what produces the effects of vegetation—it seems probable that there is a greater mass of brilliant colouring and picturesque beauty, produced by plants in the temperate, than in the tropical regions.

There are several reasons which lead us to this conclusion. In the tropics, a greater proportion of the surface is covered either with dense forests or with barren deserts, neither of which can exhibit many flowers. Social plants are less common in the tropics, and thus masses of colour are less frequently produced. Individual objects may be more brilliant and striking, but the general effect will not be so great, as that of a smaller number of less conspicuous plants, grouped together in masses of various colours, so strikingly displayed in the meadows and groves of the temperate regions.

The changing hues of autumn, and the tender green of spring, are particular beauties which are not seen in tropical regions, and which are quite unsurpassed by anything that exists there. The wide expanse of green meadows and rich pastures is also wanting; and, however much individual objects may please and astonish, the effect of the distant landscape is decidedly superior in the temperate parts of the world.

The sensations of pleasure we experience on seeing natural objects, depends much upon association of ideas with their uses, their novelty, or their history. What causes the sensations we feel on gazing upon a waving field of golden corn? Not, surely, the mere beauty of the sight, but the associations we connect with it. We look on it as a national blessing, as the staff of life, as the most precious produce of the soil; and this makes it beautiful in our eyes.

So, in the tropics, the broad-leaved banána, beautiful in itself, becomes doubly so, when looked upon as producing a greater quantity of food in a given time, and on a limited space, than any other plant. We take it as a type of the luxuriance of the tropics,—we look at its broad leaves, the produce of six months' growth,—we think of its delicious and wholesome fruit: and all this is beauty, as we gaze upon it.

In the same manner, a field of sugar-cane or an extensive plantation of cotton produces similar sensations: we think of the thousands they will feed and clothe, and the thought clothes them with beauty.

Palms too are subject to the same influence. They are elegant and graceful in themselves; they are almost all useful to man; they are associated with the brightness and warmth of the tropics: and thus they acquire an additional interest, a new beauty.

To the naturalist everything in the tropics acquires this kind of interest, for some reason or other. One plant is a tropical form, and he examines it with curiosity and delight. Another is allied to some well-known European species, and this too attracts his attention. The structure of some are unknown, and he is pleased to examine them. The locality of another is doubtful, and he feels a great pleasure in determining it. He is ever examining individual objects, and confounds his own interest in them, from a variety of causes, with the sensations produced by their beauty, and thus is led to give exaggerated descriptions of the luxuriance and splendour of the vegetation.

As most travellers are naturalists, this supposition will account for the ideas of the tropics generally obtained from a perusal of their works.

If I have come to a different conclusion, it is not that I am incapable of appreciating the splendours of tropical scenery, but because I believe that they are not of the kind usually represented, and that the scenery of our own land is, of its own kind, unsurpassed: there is nothing approaching it in the tropics, nor is the scenery of the tropics to be found with us. There,—singular forms of stems and climbers, gigantic leaves, elegant palms, and individual plants with brilliant flowers, are the characteristic features. Here,—an endless carpet of verdure, with masses of gay blossoms, the varying hues of the foliage, and the constant variety of plain and forest, meadow and woodland, more than individual objects, are what fill the beholder with delight.

CHAPTER XVI

OBSERVATIONS ON THE ZOOLOGY OF THE AMAZON DISTRICT.

A. Mammalia

Notwithstanding the luxuriance of the vegetation, which might be supposed to afford sustenance, directly or indirectly, to every kind of animal life, the Amazon valley is remarkably deficient in large animals, and of Mammalia generally has a smaller number both of species and individuals, than any other part of the world of equal extent, except Australia. Three small species of deer, which occur but rarely, are the only representatives of the vast herds of countless species of deer and antelopes and buffaloes which swarm in Africa and Asia, and of the wild sheep and goats of Europe and North America. The tapir alone takes the place of the elephants and rhinoceroses of the Old World. Two or three species of large Felidæ, and two wild hogs, with the capybára and páca, comprise almost all its large game; and these are all thinly scattered over a great extent of country, and never occur in such large numbers as do the animals representing them in other parts of the world.

Those singular creatures, the sloths, the armadilloes, and the ant-eaters, are very generally distributed, but only occur singly and sparingly. The small agoutis are perhaps rather more plentiful; but almost the only animals found in any numbers are the monkeys, which are abundant, both in species and individuals, and are the only mammalia that give some degree of life to these trackless forests, which seem peculiarly fitted for their development and increase.

I met with twenty-one species of these animals, some of which I had no opportunity of examining. Several others exist; but it is necessary to reside for some years in each locality, in order to meet with all the different kinds. I subjoin a list of the species, with the localities in which they were found.

MONKEYS FOUND ON THE AMAZON AND THE RIO NEGRO

1. Mycetes seniculus, Geoff.; on the Rio Negro and the north bank of the Amazon.

2. Mycetes caraya, Gray; on the Upper Amazon.

3. Mycetes beelzebub, Br. Mus.; Pará.

4. Lagothrix Humboldtii, Geoff.; Upper Amazon and west of Rio Negro.

5. Ateles paniscus, Geoff.; Guiana, north bank of Amazon and east of Rio Negro.

6. Cebus apella, Erxl. (?); Amazon and Rio Negro.

7. Cebus gracilis, Spix; Rio Negro and Upper Amazon.

8. Callithrix sciureus, Geoff.; the whole Amazon valley.

9. Callithrix torquatus (amictus, Geoff.); Upper Rio Negro.

10. Callithrix personatus, Geoff.; south bank of Upper Amazon.

11. Nyctipithecus trivirgatus, Humb.; Upper Rio Negro.

12. Nyctipithecus felinus, Spix; Upper Amazon.

13. Pithecia irrorata (hirsuta, Spix); south bank of Upper Amazon.

14. Pithecia——, north of Upper Amazon.

15. Brachiurus satanas, Br. Mus.; Guiana, east bank of Rio Negro.

16. Brachiurus oakary, Spix; Upper Rio Negro.

17. Brachiurus rubicundus, Isid.; Upper Amazon.

18. Brachiurus——, south side of Upper Amazon.

19. Jacchus bicolor, Spix; north of the Amazon and Rio Negro.

20. Jacchus tamarin, Br. Mus.; Pará.

21. Jacchus n.s., Upper Rio Negro.

Of the above, the first seven have prehensile tails, a character only found among the monkeys of America. The howlers, forming the genus Mycetes, are the largest and most powerful. They have a bony vessel situated beneath the chin, and a strong muscular apparatus in the throat, which assists in producing the loud rolling noise from which they derive their name, and which appears as if a great number of animals were crying in concert. This, however, is not the case; a full-grown male alone makes the howling, which is generally heard at night, or on the approach of rain.

The annexed list of the other larger mammalia of the Amazon district, will serve to confirm the statement of the extreme poverty of these regions in that class of animals. Owing to the loss of my notes and specimens, many of the specific names are doubtful: such are marked thus—?

Phyllostoma hastatum.—This is a common bat on the Amazon, and is, I believe, the one which does much injury to the horses and cattle by sucking their blood; it also attacks men, when it has opportunity. The species of blood-sucking bats seem to be numerous in the interior. They do not inhabit houses, like many of the frugivorous bats, but enter at dusk through any aperture they may find. They generally attack the tip of the toe, or sometimes any other part of the body that may be exposed. I have myself been twice bitten, once on the toe, and the other time on the tip of the nose; in neither case did I feel anything, but awoke after the operation was completed: in what way they effect it is still quite unknown. The wound is a small round hole, the bleeding of which it is very difficult to stop. It can hardly be a bite, as that would awake the sleeper; it seems most probable that it is either a succession of gentle scratches with the sharp edge of the teeth, gradually wearing away the skin, or a triturating with the point of the tongue, till the same effect is produced. My brother was frequently bitten by them, and his opinion was, that the bat applied one of its long canine teeth to the part, and then flew round and round on that as a centre, till the tooth, acting as an awl, bored a small hole; the wings of the bat serving, at the same time, to fan the patient into a deeper slumber. He several times awoke while the bat was at work, and though of course the creature immediate flew away, it was his impression that the operation was conducted in the manner above described. Many persons are particularly annoyed by bats, while others are free from their attacks. An old Mulatto at Guia, on the Upper Rio Negro, was bitten almost every night, and though there were frequently half-a-dozen other persons in the room, he would be the party favoured by their attentions. Once he came to us with a doleful countenance, telling us, he thought the bats meant to eat him up quite, for, having covered up his hands and feet in a blanket, they had descended beneath his hammock of open network, and, attacking the most prominent part of his person, had bitten him through a hole in his trousers! We could not help laughing at the catastrophe, but to him it was no laughing matter.

Senhor Brandão, of Manaquery, informed me that he had once an Indian girl in his house, who was much subject to the attacks of the bats. She was at length so much weakened by loss of blood, that fears were entertained of her life, if they continued their attacks; and it was found necessary to send her to a distance, where these bloodthirsty animals did not abound.

The wound made by them is very difficult to heal, especially in its usual locality—the tip of the great toe, as it generally renders a shoe unbearable for a day or two, and forces one to the conclusion that, after the first time, for the curiosity of the thing, to be bitten by a bat is very disagreeable. They will, however, very rarely enter a lighted room, and for this reason the practice of burning a lamp all night is almost universal.

Tapirus Americanus.—The Tapir is common over the whole Amazon district, but is nowhere very abundant. It feeds on leaves and a great many different kinds of fruits, and sometimes does much injury in the mandiocca-fields of the Indians. Its flesh is very good eating, and is considered very wholesome, and is even said to be a remedy for the ague. It is a very shy and timid animal, wandering about principally at night. When the Indian discovers a feeding-place, he builds a stage between two trees, about eight feet above the ground, and there stations himself soon after dusk, armed with a gun, or with his bow and arrow. Though such a heavy animal, the tapir steps as lightly as a cat, and can only be heard approaching by the gentle rustling of the bushes; the slightest sound or smell will alarm it, and the Indian lies still as death for hours, till the animal approaches sufficiently near to be shot, or until, scenting its enemy, it makes off in another direction. I have accompanied the Indians on these expeditions, but always without success.

Coassus nemorivagus.

C. rufus.—These are the small white and red deer of the forests, found in all parts of the Amazon. They have very small unbranched horns.

Mazama campestris?—The "Viado galera," or horned deer of the Rio Branco, is probably of this species. It has small branched horns, and inhabits the open plains, never the thick forests.

Dicotyles taiaçu. The smaller wild Hog. Taititú of the Indians.

D. labiatus?—The larger species, called by the natives "Taiaçu."

There seems to be also a third species, of the same size as the last.

Arctopithecus flaccidus? Preguiça real. Ai, (Lingoa Geral). The great Sloth.

Bradypus torquatus. Ai, (Lingoa Geral).—These and some other species of sloths are not uncommon. They feed entirely on leaves, preferring those of the Cecropias. They are frequently attacked by the harpy eagle, and are also eaten by the Indians.

Myrmecophaga jubata. Tamanduá assu, (Lingoa Geral). "The great Ant-eater."—This animal is rare, but widely distributed. During rain it turns its long bushy tail up over its back and stands still; the Indians, when they meet with one, rustle the leaves, and it thinks rain is falling, and turning up its tail, they take the opportunity of killing it by a blow on the head with a stick. It feeds on the large termites, or white ants, tearing up with its powerful claws the earth and rotten wood in which their nests are made. The Indians positively assert that it sometimes kills the jaguar, embracing it and forcing in its enormous claws, till they mutually destroy each other. They also declare that these animals are all females, and believe that the male is the "curupíra," or demon of the forests: the peculiar organisation of the animal has probably led to this error. It lives entirely on the ground.

Tamandua tetradactylus? The smaller Prehensile-tailed Ant-eater.—This animal is entirely arboreal, feeding on the tree termites; it has no nest, and sleeps in a fork of a tree with its head bent under its body.

Cyclothurus didactylus. Tamanduái, (Lingoa Geral). The small Silky-haired Ant-eater,—is arboreal, and rather abundant. There is another species much smaller, and as white as cotton; but it is rare, and I never met with it.

Priodonta gigas? Tatuassú, (Lingoa Geral). The great Armadillo.—Rather scarce.

Tatusia septemcinctus? Tatu, (Lingoa Geral).—This and another very small species are the most abundant in the Amazon district, but can seldom be procured except by hunting with dogs. All the kinds are eaten, and their flesh is very white and delicate.

Didelphis–. Opossum. Mucúra, (Lingoa Geral).—Several species are found. They frequent the neighbourhood of houses, and attack poultry. The young are carried in an abdominal pouch, like the kangaroos, and have their little prehensile tails twisted round that of the mother.

Hydrochœrus capybara. Capywára, (Lingoa Geral).—This animal is found on all the river-banks. It feeds on grass, and takes to the water and dives when pursued. It is sometimes eaten, but is not considered very good.

Cœlogenis paca. Páca. (Lingoa Geral).—This animal is generally abundant. It is nocturnal, and is much esteemed for its meat, which is the very best the country produces, being fat, delicate, and very tender.

Dasyprocta nigricans, Natt. Black Agouti. Cotía, (Lingoa Geral).—This species is found on the Rio Negro.

D. punctata? Yellow Agouti.—This is probably the common Amazon species.

D. agouti? Cotiwya. (Lingoa Geral).—A smaller species, very widely distributed. All are eaten, but the meat is rather dry and tasteless.

Cercolabes prehensilis. The Brazilian Porcupine.—This animal is scarce. It is eaten by the Indians.

Echimys–. Several species of these curious, spinous, rat-like animals are found on the Upper Rio Negro.

Cercoleptes caudivolvus. The Potto.—It is a nocturnal animal, and inhabits the banks of the Upper Amazon.

Nasua olivacea? Coatí.—Two species, the "Coatí" and the "Coatí mondi" of the Indians, are found on the Amazon.

Lontra Brasiliensis? The Brazilian Otter,—is abundant on the Rio Negro.

Galera barbara. Irára, (Lingoa Geral). Teeth, . This is a curious animal, somewhat allied to the bears. It lives in trees, and eats honey, whence probably its Indian name,—from Irá, in the Lingoa Geral, "honey."

Vulpes–? A wild dog, or fox, of the forests; it hunts in small packs; it is easily domesticated, but is very scarce.

Leopardus concolor. The Puma. In the Lingoa Geral, Sasurána, "the false deer," from its colour.

L. onça. The Jaguar. Jauarité, (Lingoa Geral).—"The Great Dog."

L. onça, var. nigra. The Black Jaguar. Jauarité pixuna, (Lingoa Geral). Tigre (Spaniards).

L. pictus and L. griseus. Tiger Cats. Maracajá, (Lingoa Geral). The Jaguar, or onça, appears to approach very nearly in fierceness and strength to the tiger of India. Many persons are annually killed or wounded by these animals. When they can obtain other food they will seldom attack man. The Indians, however, assert that they often face a man boldly, springing forward till within a few feet of him, and then, if the man turns, they will attack him; the hunters will sometimes meet them thus face to face, and kill them with a cutlass. They also destroy them with the bow and arrow, for which purpose an old knife-blade is used for the head of the arrow; and they say it is necessary not to pull too strong a bow, or the arrow will pass completely through the body of the animal, and not do him so much injury as if it remains in the wound. For the same reason, in shooting with a gun, they use rough leaden cylinders instead of bullets, which make a larger and rougher wound, and do not pass so readily quite through the body. I heard of one case, of a jaguar entering an Indian's house, and attacking him in his hammock.

The jaguar, say the Indians, is the most cunning animal in the forest: he can imitate the voice of almost every bird and animal so exactly, as to draw them towards him: he fishes in the rivers, lashing the water with his tail to imitate falling fruit, and when the fish approach, hooks them up with his claws. He catches and eats turtles, and I have myself found the unbroken shells, which he has cleaned completely out with his paws; he even attacks the cow-fish in its own element, and an eye-witness assured me he had watched one dragging out of the water this bulky animal, weighing as much as a large ox.

A young Portuguese trader told me he had seen (what many persons had before assured me often happened) an onça feeding on a full-grown live alligator, tearing and eating its tail. On leaving off, and retiring a yard or two, the alligator would begin to move towards the water, when the onça would spring upon it, and again commence eating at the tail, during which time the alligator lay perfectly still. We had been observing a cat playing with a lizard, both behaving in exactly the same manner, the lizard only attempting to move when the cat for a moment left it; the cat would then immediately spring upon it again: and my informant assured me that he had seen the jaguar treating the alligator in exactly the same way.

The onça is particularly fond of dogs, and will carry them off in preference to any other animal. When one has been committing any depredations, it is a common thing to tie a dog to a tree at night, the howling of which attracts the onça, which comes to seize it, and is then shot by a person concealed for the purpose.

It is a general belief among the Indians and the white inhabitants of Brazil, that the onça has the power of fascination. Many accounts are given to prove this; among others, a person informed me, that he had seen an onça standing at the foot of a high tree, looking up into it: on the top was a guariba, or howling-monkey, looking down at the onça, and jumping about from side to side, crying piteously; the onça stood still; the monkey continued descending lower and lower on the branches, still uttering its cries, till at length it fell down at the very feet of the onça, which seized and devoured it. Many incidents of this kind are related by persons who have witnessed them; but whether they are exaggerated, or are altogether imaginary, it is difficult to decide. The belief in them, by persons best acquainted with the habits of the animal, is universal.

Of the smaller Tiger-cats, there are several kinds, but having lost my collection of skins, I cannot ascertain the species. The Puma is considered much less fierce than the jaguar, and is very little feared by the inhabitants. There are several varieties of the jaguar, distinguished by the Indians by different names. The black variety is rarer than the others, and is generally thought to be quite distinct; in some localities it is unknown, while in others it is as abundant as the ocellated variety.

Many small rodent animals—squirrels, rats, etc.—complete the terrestrial mammalia of the Amazon district.

The waters of the Amazon, up even to the base of the Andes, are inhabited by several species of true Cetacea, of which, however, we have as yet but very scanty information.

Two, if not more, species of Dolphins are common in every part of the Amazon, and in almost all of its tributaries. They are found above the falls of the Rio Negro, and in the Cassiquiare and Upper Orinooko. They vary in size and colour, and two of them have distinct Indian names.—Piraiowára (Fish-dog), and Tucuxí.

D'Orbigny mentions their being killed by the inhabitants of Bolivia to make oil. In the Lower Amazon and Rio Negro they are scarcely ever caught, and I was unable to obtain a specimen. The species described by D'Orbigny is probably distinct, as he mentions their being twenty feet long, whereas, none I have seen could have exceeded six or seven.

Herbivorous Cetacea are also found in the Amazon; they are called by the Brazilians, Peixe boi, or cow-fish, and by the Indians, Juarouá.

It has not yet been ascertained, whether the cow-fish of the Amazon is the same as the Manatus of the West Indies and the coasts of Guiana, or a distinct species. All the accounts of the Manatus Americanus mention it as being twelve or fifteen feet long on the average, and sometimes reaching twenty. Those of the Amazon appear to average seven or eight feet only; of five or six specimens I have myself seen, none have exceeded this; Lieutenant Smyth saw one on the Upper Uaycáli, of the same size; and Condamine describes the one he saw as not being larger.

The inhabitants of the Amazon give accounts of three kinds, which they seem to consider distinct, one smaller, and one larger than the common kind, and differing also in the shape of the tail and fins, and in the colour.

The West Indian species is always described as having external nails on the edge of the fin, or fore-arm. This I never observed in the Amazon species; though in cutting the edge of the fin to take out the bones entire, I must have noticed them, had they been as prominent as they are usually described; neither does Lieutenant Smyth mention them, though he could hardly have overlooked so singular an external character.

I am therefore inclined to think that the Amazon possesses one or two distinct species. Having carefully prepared a skin and skeleton of a fine male (which, with the rest of my collections, was lost on the voyage home), I did not describe it so minutely as I otherwise should have done, but have some notes, referring to male and female specimens, which I will now give:—

Manatus of the Amazon.

Peixe boi, of the Portuguese.

Vaca marina, of the Spaniards.

Juarouá, of the Indians' Lingoa Geral.

The mammæ of the female are two, one close to the base of each fin behind. The muzzle is blunt, fleshy, and covered with numerous stiff bristles; the nostrils are on the upper part of it, and lunate. The lips, thick, fleshy, and bristly, and the tongue rough. The skin is lead-colour, with a few pinkish-white marblings on the belly; others have the whole of the neck and fore-part of the body beneath cream-colour, and another spot of the same colour on the underside of the tail. The skin is entirely smooth, resembling india-rubber in appearance, and there are short hairs scattered over it, about an inch apart; it is an inch thick on the back, and a quarter of an inch on the belly; beneath it, is a layer of fat, of an inch or more in thickness, enveloping every part of the body, and furnishing from five to ten gallons of oil.
