Toby earnestly conjured me to continue the ascent, assuring me that a little more exertion would bring us to the summit, and that then in less than five minutes we should find ourselves at the brink of the stream, which must necessarily flow on the other side of the ridge.

'Do not,' he exclaimed, 'turn back, now that we have proceeded thus far; for I tell you that neither of us will have the courage to repeat the attempt, if once more we find ourselves looking up to where we now are from the bottom of these rocks!'

I was not yet so perfectly beside myself as to be heedless of these representations, and therefore toiled on, ineffectually endeavouring to appease the thirst which consumed me, by thinking that in a short time I should be able to gratify it to my heart's content.

At last we gained the top of the second elevation, the loftiest of those I have described as extending in parallel lines between us and the valley we desired to reach. It commanded a view of the whole intervening distance; and, discouraged as I was by other circumstances, this prospect plunged me into the very depths of despair. Nothing but dark and fearful chasms, separated by sharp-crested and perpendicular ridges as far as the eye could reach. Could we have stepped from summit to summit of these steep but narrow elevations we could easily have accomplished the distance; but we must penetrate to the bottom of every yawning gulf, and scale in succession every one of the eminences before us. Even Toby, although not suffering as I did, was not proof against the disheartening influences of the sight. But we did not long stand to contemplate it, impatient as I was to reach the waters of the torrent which flowed beneath us. With an insensibility to danger which I cannot call to mind without shuddering, we threw ourselves down the depths of the ravine, startling its savage solitudes with the echoes produced by the falling fragments of rock we every moment dislodged from their places, careless of the insecurity of our footing, and reckless whether the slight roots and twigs we clutched at sustained us for the while, or treacherously yielded to our grasp. For my own part, I scarcely knew whether I was helplessly falling from the heights above, or whether the fearful rapidity with which I descended was an act of my own volition.

In a few minutes we reached the foot of the gorge, and kneeling upon a small ledge of dripping rocks, I bent over to the stream. What a delicious sensation was I now to experience! I paused for a second to concentrate all my capabilities of enjoyment, and then immerged my lips in the clear element before me. Had the apples of Sodom turned to ashes in my mouth, I could not have felt a more startling revulsion. A single drop of the cold fluid seemed to freeze every drop of blood in my body; the fever that had been burning in my veins gave place on the instant to death-like chills, which shook me one after another like so many shocks of electricity, while the perspiration produced by my late violent exertions congealed in icy beads upon my forehead. My thirst was gone, and I fairly loathed the water. Starting to my feet, the sight of those dank rocks, oozing forth moisture at every crevice, and the dark stream shooting along its dismal channel, sent fresh chills through my shivering frame, and I felt as uncontrollable a desire to climb up towards the genial sunlight as I before had to descend the ravine.

After two hours' perilous exertions we stood upon the summit of another ridge, and it was with difficulty I could bring myself to believe that we had ever penetrated the black and yawning chasm which then gaped at our feet. Again we gazed upon the prospect which the height commanded, but it was just as depressing as the one which had before met our eyes. I now felt that in our present situation it was in vain for us to think of ever overcoming the obstacles in our way, and I gave up all thoughts of reaching the vale which lay beyond this series of impediments; while at the same time I could not devise any scheme to extricate ourselves from the difficulties in which we were involved.

The remotest idea of returning to Nukuheva, unless assured of our vessel's departure, never once entered my mind, and indeed it was questionable whether we could have succeeded in reaching it, divided as we were from the bay by a distance we could not compute, and perplexed too in our remembrance of localities by our recent wanderings. Besides, it was unendurable the thought of retracing our steps and rendering all our painful exertions of no avail.

There is scarcely anything when a man is in difficulties that he is more disposed to look upon with abhorrence than a rightabout retrograde movement-a systematic going over of the already trodden ground: and especially if he has a love of adventure, such a course appears indescribably repulsive, so long as there remains the least hope to be derived from braving untried difficulties.

It was this feeling that prompted us to descend the opposite side of the elevation we had just scaled, although with what definite object in view it would have been impossible for either of us to tell.

Without exchanging a syllable upon the subject, Toby and myself simultaneously renounced the design which had lured us thus far-perceiving in each other's countenances that desponding expression which speaks more eloquently than words.

Together we stood towards the close of this weary day in the cavity of the third gorge we had entered, wholly incapacitated for any further exertion, until restored to some degree of strength by food and repose.

We seated ourselves upon the least uncomfortable spot we could select, and Toby produced from the bosom of his frock the sacred package. In silence we partook of the small morsel of refreshment that had been left from the morning's repast, and without once proposing to violate the sanctity of our engagement with respect to the remainder, we rose to our feet, and proceeded to construct some sort of shelter under which we might obtain the sleep we so greatly needed.

Fortunately the spot was better adapted to our purpose than the one in which we had passed the last wretched night. We cleared away the tall reeds from the small but almost level bit of ground, and twisted them into a low basket-like hut, which we covered with a profusion of long thick leaves, gathered from a tree near at hand. We disposed them thickly all around, reserving only a slight opening that barely permitted us to crawl under the shelter we had thus obtained.

These deep recesses, though protected from the winds that assail the summits of their lofty sides, are damp and chill to a degree that one would hardly anticipate in such a climate; and being unprovided with anything but our woollen frocks and thin duck trousers to resist the cold of the place, we were the more solicitous to render our habitation for the night as comfortable as we could. Accordingly, in addition to what we had already done, we plucked down all the leaves within our reach and threw them in a heap over our little hut, into which we now crept, raking after us a reserved supply to form our couch.

That night nothing but the pain I suffered prevented me from sleeping most refreshingly. As it was, I caught two or three naps, while Toby slept away at my side as soundly as though he had been sandwiched between two Holland sheets. Luckily it did not rain, and we were preserved from the misery which a heavy shower would have occasioned us. In the morning I was awakened by the sonorous voice of my companion ringing in my ears and bidding me rise. I crawled out from our heap of leaves, and was astonished at the change which a good night's rest had wrought in his appearance. He was as blithe and joyous as a young bird, and was staying the keenness of his morning's appetite by chewing the soft bark of a delicate branch he held in his hand, and he recommended the like to me as an admirable antidote against the gnawings of hunger.
