resource if we wished to
advance, and as for retreating, all thoughts of that sort had been long
abandoned.

After I had signified my assent, Toby, without uttering a a single word,
crawled along the dripping ledge until he gained a point from whence
he could just reach one of the largest of the pendant roots; he shook
it--it quivered in his grasp, and when he let it go it twanged in the
air like a strong, wire sharply struck. Satisfied by his scrutiny, my
light limbed companion swung himself nimbly upon it, and twisting his
legs round it in sailor fashion, slipped down eight or ten feet, where
his weight gave it a motion not un-like that of a pendulum. He could not
venture to descend any further; so holding on with one hand, he with the
other shook one by one all the slender roots around him, and at last,
finding one which he thought trustworthy, shifted him self to it and
continued his downward progress.

So far so well; but I could not avoid comparing my heavier frame and
disabled condition with his light figure and remarkable activity;
but there was no help for it, and in less than a minute's time I was
swinging directly over his head. As soon as his upturned eyes caught a
glimpse of me, he exclaimed in his usual dry tone, for the danger did
not seem to daunt him in the least, 'Mate, do me the kindness not to
fall until I get out of your way;' and then swinging himself more on
one side, he continued his descent. In the mean time I cautiously
transferred myself from the limb down which I had been slipping to a
couple of others that were near it, deeming two strings to my bow better
than one, and taking care to test their strength before I trusted my
weight to them.

On arriving towards the end of the second stage in this vertical
journey, and shaking the long roots which were round me, to my
consternation they snapped off one after another like so many pipe
stems, and fell in fragments against the side of the gulf, splashing at
last into the waters beneath.

As one after another the treacherous roots yielded to my grasp, and fell
into the torrent, my heart sunk within me. The branches on which I was
suspended over the yawning chasm swang to and fro in the air, and I
expected them every moment to snap in twain. Appalled at the dreadful
fate that menaced me, I clutched frantically at the only large root
which remained near me, but in vain; I could not reach it, though my
fingers were within a few inches of it. Aga
