working diligently with their knives two days sufficed to make guns, axe, and spear as good as ever. ossaroo also made himself a new bow and a full quiver of arrows.
on the third morning, after breakfasting, all three set out with the determination not to leave any portion of the cliff unexamined.
the part which lay between their hut and the cave, karl had already scrutinised with great care; so they went direct to the point where he had left off, and there commenced their new survey.
it is true they had already examined the cliffs all around; but this was just after they arrived in the valley, and the purpose of that exploration was very different from that of the present one.
then they were only looking for a place by which they might climb out; and the idea of making ladders had not occurred to them.
now that this scheme had suggested itself, they entered upon their second survey with the view of ascertaining whether it was practicable or possible. consequently, they went in search of facts of a different nature—viz., to see if there existed a series of ledges, one above another, that could be spanned by an equal number of such ladders as they might be able to construct.
that they could make ladders of a prodigious length—allowing sufficient time for the execution of the work—all felt confident. they knew that the thibet pine-trees—the same sort as they had used in making the bridge for the glacier crevasse—grew in great numbers not far from their hut; and by selecting some of the slenderest trunks of these, they would have the sides of as many ladders as they might want, almost ready made, and each forty or fifty feet in length.
if there should only be discovered a series of ledges, with not more than forty feet space between each two, there would be a fair hope of their being able to escalade the cliff, and escape from a place which, although one of the pleasantest-looking spots in the world, had now become to them loathsome as the interior of a dungeon.
sure enough, and to the great joy of all, such a set of shelves was soon after presented to their eyes—having, at least in appearance, all the requirements of which they were in search. the spaces between no two of them appeared to be greater than thirty feet, some were much nearer to each other.
the part of the cliff where these terraces were found was not quite so low, as that where karl had made his measurement. it did not appear, however, to be more than three hundred and fifty feet—a fearful height, it is true—but nothing when compared with other sections of the same precipice. to reach to its top, more than a dozen ladders would be required—each between twenty and thirty feet in length. the labour of making these ladders, with such tools as they had, might be looked upon as something stupendous—sufficient, you might suppose, to deter them from the task. but you must endeavour to realise the situation in which they were placed—with no other hope of being delivered from their mountain prison—and with this idea in your mind, you will comprehend why they should have been willing to undertake even a far greater labour. of course, they did not expect to complete it in a day, neither in a week, nor in a month: for they well knew that it would take several months to make the number of ladders that would be required. and then there would be the additional labour of getting each into its place: as all, after the first one, would have to be carried up the cliff to the ledge for which it should be constructed. indeed, to raise ladders of thirty feet in the manner contemplated, would seem an impossibility—that is, for such strength or mechanism as they could command.
and so it might have proved, had they intended to make these ladders of the ordinary weight. but they foresaw this difficulty, and hoped to get over it by making them of the very lightest kind—something that would just carry the weight of a man.
becoming more than half satisfied that at this point the precipice might be scaled in the manner contemplated, they remained upon the ground in order to give it a thorough examination. that done, they intended to make the complete circuit of the valley, and ascertain whether there might not be some other place still easier of ascent.
the point where they had halted was behind the tract of heavily-timbered forest—of which caspar had spoken, and which up to this time none of them had entered. between the trees and the cliff they were now contemplating, there was a narrow strip of ground destitute of timber; and covered with a shingle of loose stones which had fallen from the mountain above. several boulders of large dimensions rested upon the ground, at short distances apart; and there was one of a pillar-shape that stood some twenty-feet high, while it was only about five or six in diameter. it bore a sort of rude resemblance to an obelisk; and one might easily have fancied that the hand of man had accomplished its erection. for all that, it was a mere freak of nature, and had probably been set up by ancient glacier ice. up one of its sides there was a series of projections, by which an active man might climb to the top; and ossaroo did climb it, partly out of playfulness, and partly, as he said, to get a better view of the cliff. the shikaree stayed only a few minutes on its top; and his curiosity having been satisfied, he had let himself down again.
