The bamboo has also a secret virtue of incalculable value to the thirsty wayfarer, overcome by the heat of a tropical sun: it is a perfect reservoir of water.
By boring a hole just under the joints of each cane more than half a litre of clear water, not very fresh, but wholesome and good, gushes out. It is rather bitter to the taste and serves to restore one's forces as well as to quench one's thirst.
The water-vine also acts as a Samaritan in the jungle. Like all the others of its sort this climbing plant closes some giant king of the forest in its cruel embrace (thus depriving it of its strength) and then falls in rich festoons from its boughs, swaying and rustling with every breath of air.
By making a cut at the extremity of one of the sprays that hang down towards the ground, a fresh, drinkable water flows out.
It is superfluous, perhaps, to add that this grand necessity for the traveller on foot may be obtained from other sources: the streams that are to be found trickling along here and there, and the huge leaves that upon drying up secrete a certain quantity of rain water within them.
So the jungle gives to eat and to drink, with wonderful abundance and variety, but woe to him who does not know her well, for she also proffers Death in a thousand unsuspected and seductive forms!
How many times in the solemn, languid hour of noontide, when bird and beast were drowsing from the heat, I have stood in the shade and interrogated the forest upon its first violators and their descendants! But my demands remained unanswered; in its superb grandeur it does not interest itself in the tragic vicissitudes of animal or vegetable lives, it makes no records, on the contrary, it quickly cancels all traces of past events.
I have vainly asked: from whence came those who have found shelter and solitude in the obscure depths of its wooded hills? How many centuries have they dwelt in those lone, wild parts? I have asked if that shy and dispersed tribe was not the remains of a once great and strong people eclipsed by a younger, stronger, and more savage race? Sometimes watching, with admiring eyes, the strange architectural forms taken by the massive trunks and graceful vines, fantastic but always majestic, I have asked the forest if it had not arisen upon the ruins of some long ago and lost civilization and if those same forms were not an inexplicable evocation of the gigantic creations of vanished genii of which I seemed in imagination to catch faint glimpses?
But the forest remained mute and kept its impenetrable secret.
