It was in thinking over some plan that kept all three of them in silence, and with such thoughts Ossaroo was as busy as the others.

Think as they would, no feasible or practicable idea could be got hold of. There were five hundred feet of a cliff to be scaled. How was that feat to be accomplished?

By making a ladder? The idea was absurd. No ladder in the world would reach to the quarter of such a height. Ropes, even if they had had them, could be in no way made available. These might aid in going down a precipice, but for going up they would be perfectly useless.

The thought even crossed their minds of cutting notches in the cliff, and ascending by that means! This might appear to be practicable, and viewing the matter from a distance it certainly does seem so. But had you been placed in the position of our travellers,—seated as they were in front of that frowning wall of granite,—and told that you must climb it by notches cut in the iron rock by your own hand, you would have turned from the task in despair.

So did they; at least the idea passed away from their thoughts almost in the same moment in which it had been conceived.

For hours they sat pondering over the affair. What would they not have given for wings; wings to carry them over the walls of that terrible prison?

All their speculations ended without result; and at length rising to their feet, they set off with gloomy thoughts toward the spot where they had already encamped.

As if to render their situation more terrible, some wild beasts,—wolves they supposed,—had visited the encampment during their absence, and had carried off every morsel of the jerked meat. This was a painful discovery, for now more than ever should they require such provision.

The stag still remained to them. Surely it was not also carried off? and to assure themselves they hurried to the pool, which was at no great distance. They were gratified at finding the deer in the pool where it had been left; the water, perhaps, having protected it from ravenous beasts.

As their former camp ground had not been well chosen, they dragged the carcass of the deer up to the hot spring; that being a better situation. There the animal was skinned, a fire kindled, and after they had dined upon fresh venison-steaks, the rest of the meat Ossaroo prepared for curing,—just as he had done that of the yak,—but in this case he took the precaution to hang it out of reach of all four-footed marauders.
