In what direction had the kite been carried off? Might it not be blown along the line of cliffs, and tossed back again into the valley?
As there appeared some probability that such a chance might arise, all three ran outward from the rocksâin order to command a better view of the precipice, on each side.
For a long time they stood watchingâin hopes that they might see the great paper-bird returning to the scene of its nativity. But it never came back; and they became at length convinced, that it never would. Indeed, the direction of the windâwhen they paused to consider itârendered the thing not only improbable, but impossible. It was blowing from the cliffs, and towards the snowy ridge. No doubt the kite had been carried up the sloping acclivity; and had either passed clear over the mountains, or become lodged in some deep defile, where the wind could no longer reach it. At all events, it was certain, that both kite and cord were lost to them for ever.
âAch! how very unfortunate!â exclaimed Caspar, in a vexed tone, when they had finally arrived at this conviction. âWhat ill-starred luck we have, to be sure!â
âNay! brother,â remarked Karl, in a tone of reproval; âdo not chide Fortune for what has happened just now. I acknowledge it is a great misfortune; but it is one for which we may justly blame ourselves, and only ourselves. By sheer negligence we have lost the kite, and along with it, perhaps, the last chance of regaining our liberty.â
âYes, you speak truly,â rejoined Caspar, in a tone of mingled regret and resignation. âIt was our fault, and we must suffer for it.â
âBut are you quite sure, brother Karl,â resumed he, after a pause, and referring to the conversation that had already passed between themââare you quite sure there are no more of these paper-bearing trees?â
âOf course,â replied the plant-hunter, âI am not positiveâthough I fear it is as I have saidâthat there are no more. It will be easy for us to determine the point, by making a complete exploration of the valley. It may be that something else might turn up which would answer the purpose equally as well. There is a birch-tree indigenous to the Himalaya mountains, found both in Nepaul and Thibet. Its bark can be stripped off in broad flakes and layers, to the number of eight or tenâeach almost as thin as common paper, and suitable for many purposes to which paper is usually applied.â
âDo you think it would do for a kite?â inquired Caspar, without waiting for Karl to finish his explanation.
âI am sure of it,â replied the botanist. âIt would serve even better than the daphne paper; and had I believed there was a chance of finding it here, I should have preferred it to that. But I do not think we shall find it. I have observed no species of birch; and I know that this one, like most of the Betulaceae, affects a much colder climate than there is in this valley. Likely enough, it grows on the mountains above; but there it is out of our reach. Could we reach it there, we should not need to be robbing it of its manifold envelope. But let us not despair,â added Karl, endeavouring to appear cheerful; âperhaps it may be found growing down here; or, if not, we may still find another grove of the daphne trees. Let us proceed on and search!â
Karl was far from being sanguine in either conjecture; and it was as well for him that he was not: for after a minute and careful exploration of the valleyâwhich occupied nearly three whole daysâneither the wished-for birch, nor the desired daphne treesânor any other material out of which a kite might be manufacturedârewarded their search.
It was of no use, therefore, to think any longer of a kite; and the subject was at length dismissed from their minds.
It is scarce possible to talk of a paper kite, without thinking of that other and greater aerostatic contrivanceâa balloon.
Karl had thought of it, long before this time; and so had Caspar, just as long: for the kite had suggested it simultaneously to the minds of both.
It may be asked why they had not entertained the thought, and endeavoured to carry it into practical effect: since a balloon would have been far more likely to have delivered them out of their âmountain prisonâ than a paper kite?
But they had entertained the thoughtâat least, Karl had done soâand examined it in all its bearings. Caspar had permitted it to pass out of his mind, under the impression that they could not make a balloon; and Karl had arrived at the same conclusion; but only from a belief that they had not the materials with which to make one. Given the materials, Karl felt quite equal to the construction of a balloonâa rude one, it is true; but one which might have served the purpose for which they required it.
During the days when they had been occupied in making the paper-bird, he had given his thoughts a good deal to this subject; for, to say the truth, he had never been very sanguine about the success of the kite experiment. He had pondered long and patiently on the subject of balloonsâendeavouring to recall to mind what little he had studied of aerostaticsâand had mentally examined all the material objects within reach, in the hope of discovering some substance out of which one might be constructed.
Unfortunately, he had not been able to think of anything that appeared to be suitable. The daphne paperâeven had it been in abundanceâwould not do: for paper of itself, however close in texture, is not strong enough to withstand the pressure of the outside airâthat is, in a balloon of sufficient size to carry any considerable weight. But it was of no use to talk of paper: since there was not enough; and Karl had given over thinking of a balloon: because there was nothing within reach likely to serve for its construction.
He knew that that great sphere would require to be air-proof. He had thought of the skins of animals; but such of these as might have been obtained in sufficient quantity, were entirely too thick and heavy to make the covering of a balloon. The hemp, of which there was an abundance, might be woven into a cloth, and then coated over by gum obtained from some tree; for in the valley were several species of gum-exuding trees. But the question was, could they manufacture a cloth out of hemp that would be light enough when thus coated over? It was very doubtful whether they couldâat all events they would have to practise the weaving trade for a long time, before they should arrive at a sufficient expertness to accomplish such a feat. The plan was too unpromising to be seriously entertained; and Karl had dismissed it, along with the whole subject of the balloon.
That had been previous to the experiment of the kite, and its unfortunate ending. But now that all hope from this quarter had been brought to an end, the balloon once more began to shape itself in his mind, as well as in that of Caspar; and for the first time they proceeded to talk over the subject together.
âCords we could have in plenty,â remarked Caspar, âbut theyâd be of no use, without the stuff to cover the great globe. They make it of silk, donât they?â
âYes,â replied Karl, âsilk is the best material for the purpose.â
âAnd why?â inquired Caspar.
âBecause it combines the three properties of lightness, strength, and closeness of texture, in a greater degree than any other known substance.â
âWould nothing else do?â
âOh, yes; many things would answer to make a balloon, that might carry up a certain amount of weight. Even a paper balloon can be constructed to take up a few poundsâa cat, or a small dog; and people in many countries have been cruel enough to dispatch such creatures into the air, not caring what became of them.â
âVery cruel indeed!â assented Caspar, who, although a hunter, was far from having an unfeeling heart. âSuch people should be sent up themselves in paper balloons.â
âYes, if paper balloons would carry them; which, unfortunately for us, they wouldnât. Even if we had an unlimited supply of paper, it would be of no use to us. We require something stronger, and more tenacious.â
âCan we not think of something? Let us try, Karl!â
âAh! dear brother, I have been trying for days, and in vain. There is nothing within this valley at all suitable for the purpose.â
âWould canvas do? Have you thought of that?â
âI have. It would be too coarse and heavy.â
âBut, with great pains, could we not make it light enough? We might choose the finer fibres of the hemp; and spin and weave it with scrupulous care. Ossaroo here is a perfect Omphale in his way. Iâll warrant he could beat Hercules with the distaff.â
âHo! brother!â exclaimed Karl, a little astonished. âYou are quite classical in your speech this morning. Where learnt you the history of Herculesâyou who have never seen the inside of a university?â
âYou forget, brother Karl, that you yourself have been my instructor in these classical themes, as you call them. Though I must tell you that, with the exception of their occasionally lending a little ornament to my speech, I have derived not the slightest advantage from them; nor is it likely I ever shall.â
âWell, Caspar,â answered the botanist, âI am not going to stand up for the classics, as you are well aware. Although I have taught you a little of their lore, it was when I had nothing to do, and you were equally idle; otherwise I should have considered that both of us were wasting time. You already know my opinions on that subjectâwhich are: that a knowledge of what is usually termed âthe classicsâ is of about as much use to a reasoning man as might be an equally profound knowledge of Chinese mnemonics. The time I have spent in the study of the dead languages has been sheer waste; and all I have learnt wont raise us a foot higher here. My knowledge of Jupiter and Juno is not likely to gain us the means of getting out of our difficulty, no more than my acquaintance with Mercury will help me to a pair of wings. So a truce to classical ideas, and let us see whether scientific ones may not serve us better just now. You have a quick invention, brother Caspar; can you think of anythingâI mean anything within our reachâthat would make the air-bag of a balloon?â
âBut could you make the balloon, if you had the stuff?â inquired Caspar, still in doubt whether any other than an experienced aeronaut could construct so wonderful a machine.
âPooh!â replied the philosopher, âthe making of a balloon is almost as easy as making a soap-bubble. Any air-tight bag, filled with heated atmosphere, becomes a balloon. The question is, what weight it can be made to carryâincluding the materials out of which it may be constructed.â
âBut how are you to get the heated air into it?â
âSimply by making a fire under an aperture left open below.â
âBut would not this air soon become cold again?â
âYes; and then the balloon would sink back to the earth from the air inside getting cooled, and becoming as heavy as that without. Of course,â continued the philosopher, âyou are aware that heated air is much lighter than the ordinary atmosphere; and that is why a balloon filled with the former, rises, and will continue rising, till it has reached that elevation, where the rarefied
