“The ground was thickly carpeted with Lycopodiums,[149] but it was also encumbered with masses of vegetable débris and a thick coating of dead leaves. Fruits of many kinds were scattered about, amongst which were numerous species of beans, some of the pods a foot long, flat and leathery in texture, others hard as stone. In one place might be seen a quantity of large empty wooden vessels; such they appeared to be, but in reality they had fallen from the Sapucaya tree. They are called Monkey’s Drinking-cups (Cuyas de Macaco), and are the capsules of the nuts sold under this appellation in Covent Garden Market. The top of the vessel is pierced with a circular hole, in which a natural lid fits easily. When the nuts ripen this lid becomes loosened, and down falls the heavy shell with a crash, scattering the nuts over the ground. The tree[150] which bears this extraordinary burthen is of immense height. It is closely allied to the Brazil-nut tree,[151] whose seeds are likewise enclosed in large wooden vessels, but these are without lids, and fall entire to the ground. It is at least 120 feet high, and rises to the noble stature of 100 feet before it throws off any branches. From twelve to twenty of these sweet edible nuts lie in a pod. The monkeys are very partial to them, and will patiently sit for hours hammering at a capsule with a stone, in order to open it; and as soon as they have succeeded, the on-lookers rush to the spot, to purloin as many as they can. The natives assail the quarreling party with stones, a proceeding which incites the monkeys to revenge themselves by a discharge of nuts. By this means the Indians load their boats without trouble, and the monkeys are left to make a fresh foray.”
In his forest wanderings, Mr. Bates was especially attracted by the colossal trees. He says that, on the whole, they had not remarkably thick stems; the great and uniform height to which they grow without throwing off a branch is a much more noticeable feature than their thickness; but at intervals he paused before a veritable giant. Only one of these huge patriarchs of the woods can flourish within a given space; it monopolizes the domain, and none but humble individuals can nestle within its shadow. The cylindrical trunks of these larger trees were generally about twenty to twenty-five feet in circumference. Von Martius, another Brazilian traveller, mentions having measured trees in the Pará district, belonging to various species (Symphonia coccinea, Lecythis spirula, and Cratæva Tapia), which were fifty to sixty feet in girth at the point where they become cylindrical! The height of the vast column-like stems could not be less than 100 feet from the ground to their lowest branch. The total height of the Pao d’Ano[152] and the Massaranduba, stem and crown together, may be computed at from 180 to 200 feet. Where one of them stands, the vast canopy of leafiness rises above the other forest trees like a domed cathedral above the minor buildings of a city.
A very curious feature in these trees is the growth of buttress-shaped projections around the lower part of their stems. The spaces between these buttresses, which may be compared to thin walls of wood, form spacious chambers, like stalls in a stable; some of them large enough to hold half-a-dozen persons. “The purpose of these structures,” says Mr. Bates, “is as obvious at the first glance, as that of the similar props of brickwork which support a high wall. They are not peculiar to one species, but are common to most of the larger forest trees. Their nature and manner of growth are explained when a series of young trees of different ages is examined. It is then seen that they are the roots, which have raised themselves ridge-like out of the earth; growing gradually upwards as the increasing height of the tree required augmented support. Thus they are plainly intended to sustain the massive crown and trunk in these crowded forests, where lateral growth of the roots in the earth is rendered difficult by the number of competitors.”
Among other remarkable inhabitants of the Brazilian wilderness, we may name the lofty Moira-tingu,[153] the Samaüma,[154] and the Massaranduba or Cow tree.[155] The Eriodendron Samaüma, or Silk-cotton tree, holds in the New World the same position as the Bombax in the Old. It rises to an enormous stature without branches, and then spreads out a glorious mass of foliage. The bark is light in colour; and the capsule pod contains a large quantity of down, of a brown tint, and exquisite silky softness. The Massaranduba is also called the Palo de Vacca, the Arbor de Lacte, the Galactodendron utile, or the Cow tree. Its bark furnishes an abundant supply of milk as pleasant to drink as that of the cow. If exposed to the air it thickens into a glue, which is excessively tenacious, and often employed to cement broken crockery. The tree has a wild, strange appearance, owing to its deeply scored, reddish, and rugged bark, a decoction of which is used as a red dye for cloth.
Did our readers ever hear of the Pashiúba, or bulging-stemmed palm?[156] It is not one of the tallest kinds, for its height, when full grown, seldom exceeds forty feet; the leaves are somewhat less drooping, and the leaflets broader, than in other species; but if less beautiful, it is, perhaps, far more remarkable. Its roots grow above ground, radiating from the trunk at an elevation of ten or twelve feet, so that the tree seems to be supported on stilts; and when it is old, a person can stand upright amongst the roots with the perpendicular stem wholly above his head! About midway, this stem bulges out in a circular swelling, which gives it its distinctive name. The roots closely resemble straight rods, but they are studded with stout thorns, whilst the trunk of the Pashiúba is perfectly smooth.
It is in the vast primeval forests of Central and Southern America, and in the leafy wildernesses of the great East Indian islands—Borneo, Sumatra, Java, Madagascar—that man may still contemplate in all its savage majesty the prodigious Flora of the Tropics. These, too, are the haunts of many remarkable animals—mammals, and birds, and reptiles—which are there comparatively safe from the pitiless persecution of the hunter and the trapper.
To obtain an idea—which, however, can only be very vague and imperfect—of the strange and imposing spectacle and the unexpected scenes which at every step astonish the traveller in the great Tropical woodlands, we must study the descriptions of those few but richly endowed adventurers who, after exploring them with the enlightened curiosity of science, have been able to embody the results in language worthy of the subject.
In the foremost rank of those who have possessed the twofold qualification of scientific knowledge and descriptive power, we must place the illustrious Humboldt. His works are a rich storehouse from which later writers have freely borrowed the materials of their essays. In reference to the phrases “ Virgin Forest,” “Primeval Forest,” he has some judicious observations:—Ought we to call, he says, by either of these appellations every kind of wild thick wood, encumbered with vigorous trees, upon which man has never laid his destructive hand? In that case they would be appropriate in a number of very different countries, under the Temperate, ay, and even under the Frigid Zone. But if we intend them to designate the impenetrability of an almost boundless forest, the impossibility of clearing a path with the pioneer’s axe between serried ranks of trees, not one of which is less than from eight to ten feet in diameter, such virgin forests belong exclusively to tropical regions. We must not believe, however, according to the ordinary story in Europe, in the creeping parasitical lianas which, by the interlacement and entanglement of their branches, render the equatorial forests impenetrable. The lianas form but a comparatively insignificant portion of the underwood. The principal obstacle is found in the arborescent plants, which leave not a space uncovered, and this, too, in a country where all vegetables spreading over the soil become ligneous. If a traveller, as soon as he arrives in a tropical clime, whether in the continent or the islands, believes, even before he has penetrated inland, that he is transported to the heart of the virgin forests, his error simply originates in his impatience to realize a long-cherished desire. All Tropical forests are not virgin forests.
The true virgin forests, notwithstanding the recent explorations of Wallace, Bates, and Agassiz, are very imperfectly known; because it is, in truth, perfectly impossible to survey them in every direction, on account of their vast extent and astonishing impenetrability. When we are told by the traveller that he opened for himself a path with his trusty hatchet, we readily understand that he achieved his boasted victory in places where the obstacles were reduced to feeble lianas and brushwood of no great density, and that he turned aside from the massive barriers formed by the closely-planted trunks of colossal trees. Than these mighty vegetable Anakim, nothing, says a naturalist, is more imperfectly known in botany. The stems of most being bare and branchless up to a considerable height, their fructification is frequently beyond the reach of man. In vain would he level them by their base: their summits remain suspended by the inter-tanglement of the neighbouring summits, and like so many Tantaluses, our travellers see themselves shunned by the fruits which their eyes devour. The rivers, those “tracks which march” through the leafy, woody depths, and the tortuous paths trodden down by generations of wild beasts in their quest after new pastures, after fresh hunting-grounds, or fountains to slake their thirst, are the only roads which can be pursued by the explorer.
