They needed no pilot to point out their course. There could be no danger of straying from it. The strait they were following was of that kind known as an igarápe, which, in the language of the Amazonian Indian, means literally “the path of the canoe,” – igarité being the name of the craft most used in the navigation of the Gapo. The strait itself might have been likened to a canal, running through a thicket, which formed on both sides a colossal hedge, laced together by an impenetrable network of parasitical plants. Unlike a canal, however, it was not of uniform breadth, here and there widening into little openings that resembled lakes, and again narrowing until the tree-tops stretching from each side touched one another, forming underneath a cool, shadowy arcade.
Up this singular waterway our adventurers advanced, under the guidance of the bordering line of verdure. Their progress was necessarily slow, as the two who could swim well were compelled to assist the others; but all were aided by a circumstance that chanced to be in their favour, – the current of the Gapo, which was going in the same direction with themselves. Herein they were greatly favoured, for the flow of the flood corresponded very nearly with the course of the igarápe; and, as they advanced, they might have fancied themselves drifting down the channel of some gently flowing stream. The current, however, was just perceptible; and though it carried them along, it could not be counted on for any great speed. With it and their own exertions they were enabled to make about a mile an hour; and although this rate might seem intolerably slow, they were not discontented, since they believed themselves to be going in the right direction. Had they been castaways in mid-ocean, the case would have been different. Such tardy travelling would have been hopeless; but it was otherwise in the forest sea that surrounded them. On one side or the other they could not be more than fifty miles from real dry land, and perhaps much less. By going right, they might reasonably hope to reach it, though detained upon the way. It was of the utmost importance, however, that the direction should be known and followed. A route transverse to it might take them a thousand miles, either way, through a flooded forest, – westward almost to the foot of the Andes, – eastward to the mouth of the Amazon! The experienced tapuyo, knowing all this, was extremely cautious in choosing the course they were now pursuing. He did not exactly keep in the line indicated by the flow of the flood. Although the echente was still going on, he knew that its current could not be at right angles to that of the river, but rather obliqued to it; and in swimming onward he made allowance for this oblique, the igarápe fortunately trending at a similar inclination.
Several hours were spent in slowly wending along their watery way, the swimmers occasionally taking a rest, stretched along the surface of the water, supported by hanging llianas or the drooping branches of the trees. At noon, however, a longer halt was proposed by the guide, to which his followers gladly gave consent. All were influenced by a double desire, – to refresh themselves not only by a good rest, but by making a meal on the cold roast macaws, several of which were strapped upon the shoulders of the tapuyo. A tree with broad, spreading branches offered a convenient place, and, climbing into it, they took their seats to await the distribution of the dinner, which was committed to the care of the ex-steward, Mozey.
Previous to ascending their dining-tree, the swimmers had been more than six hours in the water, and, as nearly as they could guess, had made about that number of miles. They congratulated themselves on having met with no hostile inhabitants of the Gapo, for the jararáca and jacaré, with the perils encountered while in the presence of these two dangerous reptiles, were fresh enough in their remembrance to inspire them with continual fear. All along the way, the Indian had been constantly upon the alert. Nothing had occurred to cause them alarm, though many strange sounds had been heard, and strange creatures had been seen. Most of these, however, were of a character to cheer rather than affright them. The sounds were mostly musical, – the voices of birds, – while the creatures seen were the birds themselves, many of beautiful forms and bright plumage, perched upon the tree-tops, or winging their way overhead. Conspicuous among them were the tiny winged creatures called humming-birds, with which the Gapo abounded. During their swim they had seen several distinct species of these lovely little sprites, flashing like meteors over the surface of the water, or darting about through the tree-tops like sparks of glistening light. They appeared to be the gnomes and elves of the place.
While eating dinner, our adventurers were favoured with an excellent opportunity of observing the habits of these graceful and almost microscopic creatures. A tree stood near, whose top was surmounted by a parasite, – a species of bignonia, – in full blossom, that with its array of sweet-scented flowers completely covered the tree, almost concealing the green foliage underneath. Over this flowery spot hundreds of humming-birds were hovering, now darting from point to point, anon poised upon swiftly whirring wings in front of an open flower, their tiny beak inserted into the corolla, therefrom to extract the savoury honey. There were several species of them, though none of them of large size, and all looking more like insects than birds. But for the swiftness of their motions, they might have passed for a swarm of wild bees (meliponae) disporting themselves among the flowers. Ralph and Rosa were delighted with the spectacle, though it was not new to them, for the warmer valleys of the Andes, through which they had passed in approaching the headwaters of the Amazon, were the favourite habitat of the humming-birds, and there a greater number of species exist than in Amazonia itself. What was new to them, however, and to the rest of the party as well, was some information imparted by the tapuyo while they sat conversing after dinner. He said that there were two kinds of these birds, which, although alike in size, beauty, bright plumage, and many other respects, were altogether distinct in their habits and ways of life. By two kinds he did not mean two species, for there were many, but two sets of species, or groups, as the Indian would have called them, had he been a student of ornithology. One set, he said, – and the several species then before their eyes belonged to it, – lived upon the juice of the flowers, and this was their only food. These frequented such open campos as those on the southern side of the Solimoës, and along the rivers running into it from that direction. They were also common in plantations, and other places where clearings had been made, or where the forest was thin and scattering, because there only could they find a sufficiency of flowers. It was only at times that they made excursions into the great water-forest, when some of the sipo plants were in blossom, just as the one before them was at that time. The species they saw did not belong to the Gapo. They had only strayed there upon a roving excursion, and would soon return to the mainland, – the treeless regions. The kinds that frequented the great forest never went out of it, and cared nothing about flowers. If seen hovering around a tree in blossom, it was only because they were in pursuit of insects, which had been attracted thither in search of the sweet juices. Upon these the forest humming-birds regularly preyed, making their exclusive diet upon flies, which they caught as much among the foliage as the flowers, darting upon the insects whenever they perched upon the leaves, and snapping them up either from the upper or under side. They built their nests upon the tips of the palm-leaves, choosing the side that was inward towards the tree, from which they suspended them. They were purse-shaped, and composed of fibres closely woven together with a thick lining of a fine, soft silk-cotton, taken from the fruit of a tree called samaüma. They did not come much into the sun, like the other kinds, but kept more in the shade, and might be often met whirring about in the aisles of the forest. Sometimes they would poise themselves in the air, right in front of a person passing through among the tree-trunks, and, after remaining till the intruder’s face would be within a few feet of them, would fly on in advance of him, and again come to a pause in the same way, repeating the manoeuvre several times in succession. All these things, averred the observant Indian, made the humming-birds that kept constantly to the forest very different from those that only visited it upon occasions, and therefore, in his opinion, they were of two distinct kinds. And his opinion was the correct one, founded on observations already made by the ornithologist, and which have resulted in the classification of the humming-birds into two great groups, the Trochilinae and Phaethorninae.
Notwithstanding the pleasant theme that formed the subject of their after-dinner discourse, it was not long continued. Both those who took part in it and those who listened were too anxious about their situation to enjoy even the most interesting conversation. As soon, therefore, as they felt sufficiently recruited by the rest, they resumed their aquatic journey. For several hours they continued to advance at the same slow rate, without encountering any incident worthy of record. The igarápe still trended in a straight line, with only here and there a slight turning to one side or the other, preserving, however, the same general direction, which was northward. This they had discovered on the night before, not by observing the polar star, which is at no time visible at the equator, nor until you have travelled several degrees to the north of it. Even when this well-known star should be seen from the low latitudes of the torrid zone, it is usually obscured by the hazy film extending along the horizon. Sirius and other northern, constellations had guided them. As the sun had been shining throughout the whole of that day as well as the preceding one, you may suppose there could be no difficulty in discovering the quarter, within a point or two of the compass, at any hour of the day. This might be true to any one travelling in a high latitude, northern or southern, or at certain seasons of the year, anywhere outside the tropics. Even within the tropics it might be done by skilful observation, if the observer knew the exact time of the year. Trevannion knew the time. He knew, moreover, that it was close upon the vernal equinox, when the sun was crossing the equatorial line, near to which they were wandering. For this reason, in the meridian hours the great orb was right over their heads, and no one – not even a skilled astronomer – could have told north from south, or cast from west.
Supposing that the igarápe should not be trending in the same direction, but imperceptibly departing from it? In that case, during the mid-hours of the day they could have had no guidance from the sky, and must have suspended their journey till the sun should begin to sink towards the west, and once more make known the points of the compass. Fortunately they needed not to make this delay. As already observed, the flow of the flood was the pilot to which they looked for keeping them in their course; and, as this still ran with a slight obliquity in the same direction as the igarápe, the latter could not have departed from the right line upon which, they had been advancing. The current had been compared with the points of the compass that morning before setting out. It was a little to the east of north. Northward, then, was the course of the swimmers.
They had drawn further inference from the direction in which the flood was setting. It proved that they had strayed from the Solimoës by its left or northern bank, and must now be somewhere among the mouths of the great river Japura. It was no consolation to discover this, but the contrary. The old tapuyo only looked graver on arriving at the conviction that such was the case. He knew that in that direction, in the vast delta formed by the unnumbered branches of the Japura, the Gapo was of great width, extending far back from the banks of this remarkable river, and dry land in that direction might be at the greatest distance. There was no alternative but to keep on, and, by deviating from the course as little as possible, they might in due time reach the limits of the flood. Actuated by this impulse and its attendant hopes, they continued their toilsome journey along “the path of the canoe.”
We have said that for several hours they encountered no incident worthy of note. It was not destined, however, for that day’s sun to set before one should arise, whose record is not a matter of choice, but necessity, since it exerted such an influence on the proceedings of the travellers as to cause a complete change in their mode of progression. What they encountered was not exactly an incident, but an obstruction. In other words, their swim was suddenly brought to an end by the ending of the igarápe!
They had arrived at the termination of this curious canal, which all at once came to a cul-de-sac, the trees closing in on both sides, and presenting an impenetrable front, that forbade farther progress. The way was equally obstructed in every other direction; for on neither side of the igarápe, throughout its whole length, had any opening been observed. At first they fancied that the water might open again beyond the obstruction, but Munday, after penetrating a short distance among the tree-trunks, returned to declare his conviction that the igarápe was at an end. Nor did it terminate by any gradual convergence of the two lines of trees. On the contrary, they came together in an abrupt circular sweep, – one of colossal size, that rose high above its fellows and spread far out, standing in the centre, like some Titanic guardian of the forest, and seeming to say to the igarápe, “Hitherto shalt thou come, but no farther!”
It was of no use remaining longer in the water for that day. Even had the obstruction not arisen, it was time to have suspended their exertions. The sun was sinking towards the tree-tops, and by the time they could get themselves snugly stowed away, and something ready for supper, it would be night. Leaving other cares for the morrow, and the morrow to take care of itself, they at once proceeded to select their sleeping-place for the night. The colossal tree that had come so unpleasantly across their track seemed to offer the very quarters they were in search of; and, without more ado, they accepted the hospitality of its wide-spreading branches.
The tree upon which they had made their roost was one of a species of which they had observed many during the day. It was the true Brazil-nut (Bertholletia excelsa), own cousin to the sapucaya; for both are of the same family, – the Lecythis, – of which there are many distinct members. Like the sapucaya, it is a denizen of the low lands and flooded forests, growing to a stupendous height. It produces large, showy flowers, which are succeeded by huge capsule-like pericarps, each enclosing a score or more of Brazil-nuts. But though the flowers are followed by the fruits, these do not all come together; and, like the orange and other tropical trees, bud, blossom, and fruit may all be observed upon the same branch, in various stages of development.
It need not be said that the nuts of the Bertholletia form one of the commercial staples of Amazonia. They are too well-known to need further description; for there are few dwelling-houses in either Europe or America where they have not been submitted to the squeeze of the nut-crackers. In the forest, where they are no man’s property, they are collected by whoever chooses to take the trouble, but chiefly by the Indians and half-breeds who dwell on the borders of the Gapo. The time to gather the Brazil-nuts is the vasante, or dry season, though there are certain tribes of savages that go nutting in their canoes during the season of the echente. But the real nut harvest is after the floods have subsided, and the trees once more stand upon dry land. Then the whole malocca of Indians, or the inhabitants of a village, proceed in a body to the places where the fruits are to be found, scattered around the stems of the tall trees that have produced them.
In gathering their crop the gleaners require to observe certain precautions, those who go under the trees covering their heads with a thick wooden cap, resembling a helmet, lest the dropping of the heavy capsules – big as a cannon-ball, and almost as heavy – might crack a skull! For this reason the monkeys of the Amazon forest, though crazy for sapucaya and Brazil-nuts, always give the Bertholletia a wide berth, never going under, but around it, in a circle whose circumference lies outside the tips of the branches. Strange to say, these creatures have no fear of the sapucaya, although its pericarps are as large and heavy as those of the Brazil-nuts. But the former do not fall to the ground, or when they do, it is only after the lid has sprung open, and the huge cup has scattered its contents, leaving it a light and empty shell. It is for this reason, as much as anything else, that the nuts of the sapucaya are scarce in the market, and command a higher price. Having escaped spontaneously from their shell, they are at the mercy of all comers, birds, quadrupeds, and monkeys; whereas the Brazil-nuts, protected by their thick woody pericarps, are not so easily accessible. Even the monkeys cannot get at them, until some animal with teeth better adapted for chiselling performs for them the service of laying open the box, and giving them a chance at the treasures contained within. This is done by several species of rodents, among which the cutia and paca are conspicuous; and one of the most comical spectacles to be seen in a South American forest is that of a group of monkeys, watching from a distance the proceedings of a paca thus employed, and then springing forward to take forcible possession of the pericarp after it has been sufficiently opened.
It was a bit of good fortune that our adventurers found lodgings upon the Bertholletia. Though more hospitality may usually be met with in an inn, it provided them with at least a portion of their supper, – the bread-stuff. They had still left a brace of the macaw squabs that had not been roasted; but Munday, as before, soon produced sufficient fire to give them a scorching, and keen appetites supplied salt, pepper, and sauce.
Supper over, our adventurers only awaited the sunset to signal them to their repose. They had already selected their beds, or what was to serve for such, – the spaces of horizontal network formed by the intertwining of luxuriant llianas. At the best, it was no better than sleeping upon a raked hurdle; but they had been already somewhat inured to an uneasy couch on the galatea, and they were every day becoming less sensitive to necessities and hardships. They were all tired with the severe exertions they had made; for although their journey had been but about six miles, it was enough to equal sixty made upon land. They felt as if they could go to sleep astride of a limb, or suspended from a branch.
It was not decreed by fate that they should find rest before being made the witnesses of a spectacle so curious, that, had they been ever so much inclined for sleep, would have kept them awake against their will.
A noise heard afar off in the forest attracted their attention. There was nothing in it to alarm them, though had they not heard it before, or something similar to it, their fears might have been excited to the utmost pitch of terror. What they heard was the lugubrious chant of a band of howling monkeys. Of all the voices of Nature that awake the echoes of the Amazonian forest, there is perhaps none so awe-inspiring as this. It is a combination of sounds, that embrace the various tones of shrieking, screaming, chattering, growling, and howling, mingled with an occasional crash, and a rattle, such as might proceed from the throat of a dying maniac. And yet all this is often the product of a single mycetes, or howling monkey, whose hollow hyoidal bone enables him to – send forth every species of sound, from the rolling of a bass drum to the sharp squeak of a penny-whistle.
“Guaribas!” quietly remarked the Mundurucú, as the distant noise was first heard.
“Howling monkeys you mean?” interrogatively rejoined Trevannion.
“Yes, patron, and the loudest howlers of the whole tribe. You’ll hear them presently. They are coming this way.”
“They’re not far off now, I should say, if one may judge by the loudness of their cries.”
“All of a mile yet, patron. It proves that the forest stretches more than a mile in that direction, else the guaribas could not be there. If there be open water between us and them, they won’t come this way. If not, we’ll have them here in ten minutes’ time. I wish we could only travel among the tree-tops as they can. We shouldn’t stay long in the Gapo.”
“Just as the Mundurucú expected,” continued the tapuyo, after a pause. “The guaribas are coming towards us. I can hear the swishing of the leaves as they pass among them. We’ll soon see them.”
The howling of the guaribas had for some time ceased, but the rustling of leaves, with the occasional snapping of a twig, to which the Indian had directed the attention of his companions, told that the troop was travelling through the tree-tops, otherwise observing a profound silence.
Soon they appeared in sight, suddenly presenting themselves upon a tall tree that stood by the side of the igarápe, about a cable’s length from that occupied by our adventurers. For some minutes the branches of the tree were seen oscillating up and down, as each black guariba sprang into it: and this continued until not less than a hundred had found lodgement upon the limbs. As the leader of the band, who was evidently chief of the tribe, caught sight of the igarápe, he was seen to pause in an abrupt and ambiguous manner, at the same moment giving utterance to a cry, easily intelligible as a word of command. It had the effect of causing those immediately behind him to come to a halt, as also the others, as they sprang successively into the tree. There could be no question as to what had caused the halt. It was the igarápe crossing the track which the guaribas were going. With them the only question was, how they were to get over it.
At the point where the howlers had clustered together, the strait was narrower than elsewhere within sight. Between the branches, extending horizontally from the opposite sides of the igarápe, there was a clear space of about twenty feet; and to the spectators it appeared improbable that any animal without wings could leap from tree to tree. The monkeys, however, did not seem to be of this opinion, but were plainly contemplating the leap; and it was evident that some of them were only restrained from taking it by an authoritative command from their chief, which held them in check. For several minutes there was a profound silence among them, undisturbed until the stragglers had all arrived in the tree, and squatted on the branches.
It was now observed that among these last were several mothers, each carrying a child upon her back, or embraced between her bare arms; the youngster with face upturned, clinging, not with teeth and toe-nail, but with hands and tail, to the neck of its maternal parent. To these the attention of the whole tribe appeared to be directed; and it was evident that they were the sole cause of the difficulty, – the impedimenta that had interrupted the onward march of the troop.
There had been confusion, accompanied by some chattering, after first coming up; but a sign from the leader had put an end to all noise, and then succeeded the silence already mentioned. During its continuance the guariba chief slowly ascended the tree, until he had attained a position elevated above all his followers. Then squatting down, with his hams firmly planted upon a branch, his long tail carefully coiled around another, he commenced his harangue with as much ceremony as if he had been chairman of a Guild-Hall dinner. Perhaps there was quite as much sense and eloquence in his speech; at all events, there was more noise: for during the ten minutes taken up by it – it had the advantage of brevity – no other sound could have been heard over the Gapo within the circuit of a mile.
His address being ended, the chief, by a series of detached speeches, seemed to invite a reply from his followers, coaxing their assent, or daring them to contradiction. There appeared to be no dissent, not one voice. The chattering that responded to the speech was delivered in a tone that spoke unanimous compliance with the proposal – whatever it was – which their chief had offered to their consideration.
Then ensued another interval of silence, much shorter than before, and again interrupted by the leader of the troop. This time, however, his words were few and to the purpose. They were pronounced in a tone of command, that called for prompt obedience, which was yielded instantaneously and without protest.
One of the strongest of the guaribas ran out upon the limb overhanging the igarápe, and, stopping at its extremity, braced himself for the leap. In another instant it was made, and the monkey was seen rushing up into the tree on the other side of the igarápe. A comrade followed, placing his four hands in the same spot, his body in a similar attitude, and making the leap so exactly like the guariba that had preceded him, that it seemed the same monkey repeating the performance. Then went another, and another, so close following, that the creatures appeared more like the links of some colossal but quick-moving chain, pulled by supernatural power across the igarápe, than a series of individual and animated beings.
