he pass, and apparently
crawling up the other side on their hands and knees, without any really
definite object in view, Leigh's arguments certainly seemed the better.

"Why, Kenyon," he concluded, "do you want to change your mind? Formerly
you were anxious to penetrate the swamp from an altogether impossible
quarter in order to arrive at our present location, and now that you
have a good open down-hill road before you, you are keen to turn your
back upon it. At least, let me have your reason for this change of
front."

"Simply this, Leigh," was the reply. "The pass itself, I now find, lies
somewhat to the north of the equator, and I am positively certain that
the man we seek will be found in some place which lies absolutely on the
equatorial line, consequently behind us, and therefore away on the other
side of the kloof."

"But why, in the name of common-sense," persisted Leigh, "_should_ your
man live on the equator, or near it at all? That's what I can't
understand."

"See here, Leigh," was the cool answer; "that was my very first clue to
this affair. _He lives on latitude Number 0, otherwise Zero_. Basing
my whole theory and reasoning upon that, I have traced him to this spot,
so I may fairly assume that my deductions are correct. However, sooner
or later we shall have to investigate this side of the pass, so if you
like we'll toss up when daylight comes, and let the coin decide for us."

Still unconvinced, though admiring the shrewdness of his comrade in
following up a mere piece of guess-work, and elaborating it into such a
strikingly correct theory, Leigh continued to urge his view of the
matter, and soon the dawn came gliding over the earth, waking all nature
with a kiss of peace, and preparing her for the advent of the glorious
orb of day.

CHAPTER SIX.

RICHARD GRENVILLE, HIS MARK.

The daylight, however, told our friends nothing very new, only Kenyon
hinted to Leigh that where the rocks below them levelled down to, and
impinged upon, the veldt, everything was most suspiciously green and
verdant, from which he inferred the presence of their old enemy, the
marsh, in the immediate vicinity; then, turning round to examine the
opposite cliff, his eye was caught by what seemed to be a curious kind
of diagram engraved upon the face of the rock, perhaps two or three
yards from the upper edge of one of its platforms, and scarce fifty feet
away from them across the intervening chasm. The appearanc
