Strange to say, at that hour when it was no longer of any concern to them, the sky became suddenly clear, and the sun shone forth with burning brilliance. But his...o...b..was now in the zenith, and of no service to point out the quarter of the compa.s.s. Within the equatorial zone, north, south, east, and west were all alike to him at that season of the year and that hour of the day. If they could but have the direction of one of these points, all would have been well. But the sun gave no sign.

For all that, the Indian hailed his appearance with a grunt of satisfaction, while a change came over his countenance that could scarce be caused by the mere brightening of the sky. Something more than cheerfulness declared itself in his dark features,--an expression of renewed hope.

"If the sun keep on to show," said he, in answer to the questioning of Trevannion, "it will be all right for us. Now it's no good. In an hour from now he'll make some shadow. Then we shall swim as straight as can be, never fear, patron! we shall get out of this sc.r.a.pe before night,-- never fear!"

These cheering words were welcome, and produced universal joy where but the moment before all was gloom.

"I think, patron," continued the tapuyo. "We may as well stop swimming for a while, till we see which way the sun goes. Then we can make a fresh start. If we keep on now, we may be only making way in the wrong direction."

The tired swimmers were only too ready to yield compliance to this bit of advice. The Mundurucu made one more endeavour to catch sight of the tree-tops, and, being still unsuccessful, resigned himself to inactivity, and along with the rest lay motionless upon the water.

CHAPTER FIFTY.

GUIDED BY A SHADOW.

In this way about an hour was spent; though by no means in solemn silence. Perfectly at ease, so far as physical comfort was concerned, upon their liquid couch the swimmers could converse, as if stretched upon a carpet of meadow-gra.s.s; and they pa.s.sed their time in discussing the chances of their ultimate escape from that cruel situation, to which an unlucky accident had consigned them. They were not altogether relieved from apprehension as to their present predicament. If the sky should become again overcast, they would be worse off than ever, since there was the loss of time to be considered. All were constantly turning their eyes upwards, and scanning the firmament, to see if there were any signs of fresh clouds.

Munday looked towards the zenith with a different design. He was watching for the sun to decline. In due time his watchfulness was rewarded; not so much by observation of the sun itself, as by a contrivance which declared the course of the luminary, long before it could have been detected by the eye.

Having cautioned the others to keep still, so that there should be no disturbance in the water,--otherwise perfectly tranquil,--he held his knife in such a way that the blade stood up straight above the surface.

Taking care to keep it in the exact perpendicular, he watched with earnest eye, as a philosopher watches the effect of some chemical combination. In a short time he was gratified by observing a _shadow_.

The blade, well balanced, cast an oblique reflection on the water; at first, slight, but gradually becoming more elongated, as the experiment proceeded.

Becoming at length convinced that he knew west from east, the tapuyo restored his knife to its place, and, calling to his companions to follow him, he struck off in the direction pointed out to him by the shadow of the steel. This would take the swimmers in an easterly direction; but it mattered not what direction so long as it carried them out of the lagoon. As they proceeded onward, the guide occasionally a.s.sured himself of keeping the same course, by repeating the experiment with his knife; but after a time he no longer needed to consult his queer sun-dial, having discovered a surer guide in the spray of the forest, which at length loomed up along the line of the horizon.

It was close upon sunset when they swam in among the drooping branches, and once more, with dripping skins, climbed up into the tops of the trees. Had it not been that they were glad to get to any port, they might have felt chagrin on discovering that chance had directed them to the very same roost where they had perched on the preceding night.

The drowned guariba which Munday had carried from the middle of the lagoon was roasted, and furnished their evening meal; and the epicure who would turn up his nose at such a viand has never tasted food under the shadow of an Amazonian forest.

CHAPTER FIFTY ONE.

AROUND THE EDGE.

Discouraged by their failure, our adventurers remained upon their perch till nearly noon of the next day, in listless la.s.situde. The exertions of the preceding day had produced a weariness that required more than a night's rest, for not only their bodies, but their spirits were under the influence of their long toil, until their state of mind bordered upon despondency. As the hours wore on, and their fatigue was gradually relieved by rest, their spirits rose in like proportion; and before the sun had reached its meridian, the instinctive desire of life sprang up within their bosoms, and once more they began to consider what steps should be taken to prolong it.

Should they make another attempt to cross the lagoon by swimming? What chance would there be of steering in the right course, any more than upon the day before? They were just as likely to go astray a second time, and perhaps with a less fortunate _finale_. If again lost amidst the waste of waters, they might not be able to get sight of the tree-tops, but swim on in circles or crooked turnings, until death, arising from sheer exhaustion, or want of food, should complete their misery.

Even the Mundurucu no longer urged the course in which he had formerly expressed such confidence; and for some time he declined giving any advice whatever,--his silence and his gloomy looks showing that he felt humiliated by the failure of his plan. No one thought of reproaching him; for although their faith in his power was not quite so strong as it had hitherto been, there was yet confidence in his superior skill. Had they been castaways from a ship, escaping in an open boat, or on some raft or spar, in the middle of the great ocean, their cook would doubtless have disputed his right to remain master. But in the midst of that strange inland sea, whose sh.o.r.es and islands consisted only of tree-tops, the Mozambique acknowledged himself to be no more than a novice.

Trevannion himself took the lead in suggesting the next plan. It was not intended to give up the idea of crossing the lagoon. It was a general belief that on the other side there must be land; and therefore to reach it became the paramount thought of the party. To go around it, by keeping upon the trees, was clearly out of the question. Even had these continued all the way with interlacing branches, still the journey would have been one that apes alone could perform. It would have occupied days, weeks, perhaps a month; and what certainty was there of finding food for such a length of time? Still, if they could not travel upon the tree-tops, what was to hinder them from going _under_ them?

Why should they not use the forest to steer by,--swimming along the edge of the trees, and making use of them at intervals for rest, and for a sleeping-place during the night?

The idea was excellent, and, coming from Trevannion himself, was of course approved without one opposing voice. Even the Indian acknowledged that it was a sagacious design, and superior to his own.

Fortunately it required but slight preparation for trial, and as the sun shone down from the zenith they forsook their resting-place, and once more betook themselves to the water, with their swimming-belts carefully adjusted again about them.

CHAPTER FIFTY TWO.

THE Ma.s.sARANDUBA.

They advanced at the rate of about a mile an hour. Could they have kept on steadily, this would have given them ten or twelve miles a day, and two or three days might have brought them to the other side of the lagoon. It was necessary, however, that they should stop at intervals to obtain rest; and their progress was further impeded by the piosoca plants,--the huge water-lilies already described,--whose broad, circular leaves, lying along the surface like gigantic frying-pans, came directly in their course. Here and there they had to traverse a tract of these lilies several acres in extent, where the rims of the rounded leaves almost touched each other; and the thick succulent stalks formed a tangle underneath, through which it was very difficult for a swimmer to make way. More than once they were compelled to go around these watery gardens for a distance of many hundreds of yards, but thus shortening the journey made in the right direction.

On account of such impediments they had not gone more than three miles from their point of starting, when the Mundurucu recommended a halt for the night, although it could not have been later than six o'clock, as could be told by the sun, still high up in the heavens.

"I am hungry, patron," said the Indian at last; "so are you all. We must have some supper, else how can we go on?"

"Supper!" echoed Trevannion. "Yes, sure enough, we are hungry. I knew that an hour ago. But upon what do you propose to sup? I see nothing but trees with plenty of leaves, but no fruit. We cannot live upon leaves like the sloth. We must be starving before we take to that."

"We shall sup upon milk, master, if you don't object to our making a camping-place close by."

"Milk!" exclaimed Tom. "What div yez say, Misther Munday? Div yez mane milk? Och! don't be after temptin' wan's stomach with a dilicacy that can't be obtained in this land av wather! Shure now we're not only a hundred modes from the tail av a cow, but a thousand, may be, from that same."

"You may be wrong there," interrupted the Paraense. "There are cows in the Gapo, as well as upon land. You have seen them yourself as we came down the river?"

"Troth, yis,--if yez mane the fish-cow," (the Irishman alluded to the _Vaca marina_, or manatee,--the _peixe-boi_ or fish-cow of the Portuguese, several species of which inhabit the Amazon waters). "But shure the great brute could not be milked, if we did cotch wan av them; an' if we did we should not take the throuble, when by sthrippin' the skin av her carca.s.s we'd get somethin' far betther for our suppers, in the shape av a fat steak."

"Yonder is what the Mundurucu means!" said the guide. "Yonder stands the cow that can supply us with milk for our supper,--ay, and with bread too to go along with it; don't you see the _Ma.s.saranduba_?"

At first they could see nothing that particularly claimed attention.

But by following the instructions of the guide, and raising their heads a little, they at length caught sight of a tree, standing at some distance from the forest edge, and so far overtopping the others as to appear like a giant among pygmies. It was in reality a vegetable giant,--the great ma.s.saranduba of the Amazon,--one of the most remarkable trees to be found even in a forest where more strange species abound than in any other part of the world. To Tom and some others of the party the words of the Mundurucu were still a mystery. How was a tree to supply them with a supper of bread and milk?

Trevannion and Richard required no further explanation. The former had heard of this singular tree; the latter had seen it,--nay, more, had drank of its milk, and eaten of its fruit. It was with great joy the young Paraense now looked upon its soaring leafy top, as it not only reminded him of a spectacle he had often observed in the woods skirting the suburbs of his native city, but promised, as the tapuyo had declared, to relieve the pangs of hunger, that had become agonisingly keen.

CHAPTER FIFTY THREE.

A VEGETABLE COW.

The tree which had thus determined them to discontinue their journey, and which was to furnish them with lodgings for the night, was the famous _palo de vaca_, or "cow-tree" of South America, known also as the _arbol de leche_, or "milk-tree." It has been described by Humboldt under the name _Galactodendron_, but later botanical writers, not contented with the very appropriate t.i.tle given to it by the great student of Nature, have styled it _Brosium_. It belongs to the natural order of the _Atrocarpads_, which, by what might appear a curious coincidence, includes also the celebrated breadfruit. What may seem stranger still, the equally famous upas-tree of Java is a scion of the same stock, an _atrocarpad_! Therefore, just as in one family there are good boys and bad boys, (it is to be hoped there are none of the latter in yours,) so in the family of the atrocarpads there are trees producing food and drink both wholesome to the body and delicious to the palate, while there are others in whose sap, flowers, and fruit are concealed the most virulent of poisons.

The ma.s.saranduba is not the only species known as _palo de vaca_, or cow-tree. There are many others so called, whose sap is of a milky nature. Some yield a milk that is pleasant to the taste and highly nutritious, of which the "hya-hya" (_Tabernaemontana utibis_), another South American tree, is the most conspicuous. This last belongs to the order of the _Apocyanae_, or dog-banes, while still another order, the _Sapotacae_, includes among its genera several species of cow-tree. The ma.s.saranduba itself was formerly cla.s.sed among the _Sapotads_.

It is one of the largest trees of the Amazonian forest, frequently found two hundred feet in height, towering above the other trees, with a top resembling an immense vegetable dome. Logs one hundred feet long, without a branch, have often been hewn out of its trunk, ready for the saw-mill. Its timber is very hard and fine grained, and will stand the weather better than most other South American trees; but it cannot be procured in any great quant.i.ty, because, like many other trees of the Amazon, it is of a solitary habit, only two or three, or at most half a dozen, growing within the circuit of a mile.

It is easily distinguished from trees of other genera by its reddish, ragged bark, which is deeply furrowed, and from a decoction of which the Indians prepare a dye of a dark red colour. The fruit, about the size of an apple, is full of a rich juicy pulp, exceedingly agreeable to the taste, and much relished. This is the bread which the Mundurucu hoped to provide for the supper of his half-famished companions.

But the most singular, as well as the most important, product of the ma.s.saranduba is its milky juice. This is obtained by making an incision in the bark, when the white sap flows forth in a copious stream, soon filling a calabash or other vessel held under it. On first escaping from the tree it is of the colour and about the consistency of rich cream, and, but for a slightly balsamic odour might be mistaken for the genuine produce of the dairy. After a short exposure to the air it curdles, a thready substance forming upon the surface, resembling cheese, and so called by the natives. When diluted with water, the coagulation does not so rapidly take place; and it is usually treated in this manner, besides being strained, before it is brought to the table.

The natives use it by soaking their _farinha_ or maize-bread with the sap, and it is also used as cream in tea, chocolate, and coffee, many people preferring it on account of the balsamic flavour which it imparts to these beverages.

The milk of the ma.s.saranduba is in great demand throughout all the district where the tree is found, both in the Spanish and Portuguese territories of tropical South America. In Venezuela it is extensively used by the negroes, and it has been remarked that these people grow fatter during the season of the year when the _palo de vaca_ is plenty.

Certain it is that no ill effects have been known to result from a free use of it; and the vegetable cow cannot be regarded otherwise than as one of the most singular and interesting productions of beneficent Nature.
