ting out almost horizontally from the sides of the chasm, twisted
themselves together in fantastic masses almost to the surface of the
stream, affording us no passage except under the low arches which they
formed. Under these we were obliged to crawl on our hands and feet,
sliding along the oozy surface of the rocks, or slipping into the deep
pools, and with scarce light enough to guide us. Occasionally we would
strike our heads against some projecting limb of a tree; and while
imprudently engaged in rubbing the injured part, would fall sprawling
amongst flinty fragments, cutting and bruising ourselves, whilst the
unpitying waters flowed over our prostrate bodies. Belzoni, worming
himself through the subterranean passages of the Egyptian catacombs,
could not have met with great impediments than those we here
encountered. But we struggled against them manfully, well knowing our
only hope lay in advancing.

Towards sunset we halted at a spot where we made preparations for
passing the night. Here we constructed a hut, in much the same way as
before, and crawling into it, endeavoured to forget our sufferings. My
companion, I believe, slept pretty soundly; but at day break, when we
rolled out of our dwelling, I felt nearly disqualified for any further
efforts. Toby prescribed as a remedy for my illness the contents of one
of our little silk packages, to be taken at once in a single dose. To
this species of medical treatment, however, I would by no means accede,
much as he insisted upon it; and so we partook of our usual morsel, and
silently resumed our journey. It was now the fourth day since we left
Nukuheva, and the gnawings of hunger became painfully acute. We were
fain to pacify them by chewing the tender bark of roots and twigs,
which, if they did not afford us nourishment, were at least sweet and
pleasant to the taste.

Our progress along the steep watercourse was necessarily slow, and by
noon we had not advanced more than a mile. It was somewhere near this
part of the day that the noise of falling waters, which we had faintly
caught in the early morning, became more distinct; and it was not long
before we were arrested by a rocky precipice of nearly a hundred feet
in depth, that extended all across the channel, and over which the wild
stream poured in an unbroken leap. On each hand the walls of the
ravine presented their overhanging sides both above and below the fall,
affording no means whatever of avoiding the cata
