above.

Tars Tarkas went in advance and as I reached the first of the
horizontal bars I drew the ladder up after me and, handing it to him,
he carried it a hundred feet further aloft, where he wedged it safely
between one of the bars and the side of the shaft. In like manner I
dislodged the lower bars as I passed them, so that we soon had the
interior of the tree denuded of all possible means of ascent for a
distance of a hundred feet from the base; thus precluding possible
pursuit and attack from the rear.

As we were to learn later, this precaution saved us from dire
predicament, and was eventually the means of our salvation.

When we reached the opening at the top Tars Tarkas drew to one side
that I might pass out and investigate, as, owing to my lesser weight
and greater agility, I was better fitted for the perilous threading of
this dizzy, hanging pathway.

The limb upon which I found myself ascended at a slight angle toward
the cliff, and as I followed it I found that it terminated a few feet
above a narrow ledge which protruded from the cliff's face at the
entrance to a narrow cave.

As I approached the slightly more slender extremity of the branch it
bent beneath my weight until, as I balanced perilously upon its outer
tip, it swayed gently on a level with the ledge at a distance of a
couple of feet.

Five hundred feet below me lay the vivid scarlet carpet of the valley;
nearly five thousand feet above towered the mighty, gleaming face of
the gorgeous cliffs.

The cave that I faced was not one of those that I had seen from the
ground, and which lay much higher, possibly a thousand feet. But so
far as I might know it was as good for our purpose as another, and so I
returned to the tree for Tars Tarkas.

Together we wormed our way along the waving pathway, but when we
reached the end of the branch we found that our combined weight so
depressed the limb that the cave's mouth was now too far above us to be
reached.

We finally agreed that Tars Tarkas should return along the branch,
leaving his longest leather harness strap with me, and that when the
limb had risen to a height that would permit me to enter the cave I was
to do so, and on Tars Tarkas' return I could then lower the strap and
haul him up to the safety of the ledge.

This we did without mishap and soon found ourselves together upon the
verge of a dizzy little balcony, with a magnificent view of the valley
spreading out below us.
