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 appearance it
presented was as undernoted, the characters being some eighteen to
twenty inches in length, and cut deeply into the soft sandstone with
some apparently blunt instrument.
"Now," said Kenyon, calling his companion's attention to this, "what the
deuce does yonder curious hieroglyphic signify? I've no knowledge of
Arabic, but I think I'm right in saying that those signs belong to the
calligraphy of no known language. To my professional eye they rather
resemble a rough gibbet with three bodies hanging from it."
It so happened that, as soon as daylight had satisfied the pair that
their foes were not hanging about in the immediate vicinity, Leigh had
quietly laid himself down to enjoy a comfortable smoke, and was at the
moment in question lying on the broad of his back, gazing at the wide
vista of country below him, and puffing away in perfect tranquillity,
with the apex of his skull pointing towards the chasm. To save himself
the trouble of rising, he lazily elevated his chin, and performed the
interesting occupation of looking, so to speak, over the top of his own
head, and then electrified Kenyon by bounding to his feet with a wild
hurrah, and shaking hands with him enthusiastically. "Found!" he fairly
yelled. "Found, as sure as there is a heaven above us!"
"Why, confound it, old fellow," said Kenyon, ruefully nursing his
bruised fingers, "whatever is the matter with you?"
"Matter!" was the reply. "Why, your hieroglyphic is as good as my
cousin looking me in the face from yonder splendid rock. The solution
of your mystery is a simple matter to me--a man, hanging head-downwards
from yonder cliff, laboriously graved those curious characters, upside
down, as we see them, upon the face of the rock, and the hand that wrote
them was the hand of Grenville."
"And the meaning?" queried the attentive Kenyon, without showing any of
his customary signs of incredulity or dissent.
"The hieroglyphic which is such a stumbling-block to you, Kenyon,
simplified, stands thus:--
"I. _v_. LIII,
"and the meaning is merely `Richard Grenville.' It was a secret sign
between my cousin and myself when we were mere schoolboys, and the
simile was drawn from the memorable sea-fight in the reign of good Queen
Bess, when Sir Richard Grenvil--God rest him for a gallant
gentleman!--`with one small ship and his English few,' fought for a day
and a night with fifty-three Spanish galleons. As a boy, my cousin--
though no descendant of the hero--was passionately devoted to this page
of history, and used to sign himself `1 _versus_ 53,' and so, by yonder
sign, I know he lives, and lives looking for me to find him, and to read
the hand he wrote, which to all others would, of course, be utterly
unintelligible." And Leigh again set to and fairly danced with joy and
excitement at this truly singular and fortunate discovery.
Whilst being thoroughly surprised, Kenyon could but congratulate himself
at seeing the hall-mark of absolute accuracy thus unexpectedly stamped
upon every link in the chain of his pet theory, and both men were now
equally eager to descend the rocky pathway--the reason for the existence
of this last being, under the circumstances, a positive enigma to them--
and recommence their search for the lost one on the other side of the
kloof.
After a hasty breakfast, however, the pair decided that, as they were
already on the spot, it would be best to thoroughly satisfy themselves
regarding their own side of the chasm, more especially as, by the time
they had descended the rocky pathway and called at the camp, it would
have been too late to attempt the ascent of the cliffs, which were now
believed by them to provide a rampart for the enemy, and a prison for
their friend.
The twain, therefore, scrambled down the rocks facing towards the north,
and quickly found, as Kenyon had predicted, that the position on that
side was rendered altogether inaccessible by the presence of the swamp,
which just here was very much in evidence. In every direction, as far
as the eye could reach, it spread itself out brightly verdant and
inviting in the sunshine, but utterly treacherous and unstable, and the
nearer it approached to the rocks the more palpable did the fraud
appear, as, at the point where the stony ground impinged upon the veldt,
the swamp was little better than stagnant pools of slimy, evil-smelling
water, overgrown with reeds and rushes.
Re-ascending the rocks, Leigh and Kenyon sheltered themselves in the
woods from the rays of the vertical sun, utilising their time by making
themselves, as they believed, thoroughly conversant with the place, and
when the day began to grow towards evening, they left the bush-clothed
heights, and again turned their faces towards the camp.
Just as the pair commenced the descent of the narrow rocky path Kenyon
suddenly paused, and drew in his breath with an angry hiss, and
following the direction of his eager gaze, Leigh looked towards their
tent, which was plainly in view, about a mile away as the crow flies.
From the height at which our friends stood, they had, of course, an
unrestricted view of the plain stretched out before them, and everything
upon it, and there, some two hundred yards from the camp, and clearly
outlined against the veldt upon which he lay stretched, was the
unwelcome figure of an unmistakable spy, who, so far as he could be made
out at that distance, wore the garments of a white man.
When he had spent quite half-an-hour in this position, and no doubt
thoroughly taken stock of his surroundings, the fellow was seen to turn
and worm his way back, until he obtained the cover of a low clump of
bush about a quarter of a mile from the camp, and was thenceforward
hidden from sight.
After some little time had elapsed, and as our friends were debating
what steps they had best take, a fresh surprise was provided for them,
as the pair distinctly saw a snow-white pigeon leave the bush in
question, describe one or two airy circles round it, and then wing its
way directly towards the cliffs across the kloof, beyond which it
quickly disappeared.
"A carrier pigeon, by Jove!" said Kenyon, "doubtless bearing a request
to Master Zero to come down and cut all our throats to-night. All
right, my friend, forewarned is forearmed, and you'll find it so this
evening, unless I am very much mistaken."
Carefully getting down to the exit of the pass, the twain commenced a
cautious stalk, and came in upon their quarry just at dusk, and great
was the astonishment and consternation of the wretched spy when the two
men quietly rose from the long grass, and, covering him with their
revolvers, peremptorily ordered him to lay down his arms; this he
promptly did in most abject fashion, and was in two minutes bound hard
and fast with his own lasso, of which most objectionable instrument his
armament consisted, backed up by a long American muzzle-loading rifle
and a light axe or tomahawk.
The captive was apparently a Spaniard, as he protested volubly in that
language--of which Kenyon had a smattering--against the gratuitous
outrage committed upon his unoffending person.
Suddenly, taking advantage of an instant when neither of his captors had
their eyes on him, the fellow darted to one side, and gave a kick at
some small object which our friends had passed unnoticed in the long
grass; this object, however, proved to be a little wicker basket, and
from this receptacle--its prison doors thrown open by the intentional
violence of its owner--there fluttered a large, black pigeon, which
circled round the heads of the party and prepared to take its flight,
just as its white predecessor had previously done. Fortunately, the
bird was dazed and confused by the blow it had received, and hovered
round the spot an instant too long. Like a flash Leigh's rifle went to
his shoulder, and the next second the bird lay in a lifeless heap upon
the ground, whilst the spy ground out a bitter Spanish curse.
The shot was a very fine one, and but few men could have accomplished it
with a repeating-rifle and a single bullet, but its success had, without
a doubt, prevented the spy from giving to his friends or followers
inopportune notice of his capture and detention.
Quickly proceeding into camp, where the rifle-shot had set their men
buzzing about like bees, a hasty meal was partaken of, and then, leaving
the tent still standing, the whole party, upwards of twenty-five in
number, at once set out for the pass, as our friends believed that if
they could once get their men up to the top of the rocky path, they
would easily be able to hold the wood and the steep and narrow way
against all comers. Finding it a matter of impossibility to get any
information out of the captive, they gagged him and walked him off with
them, Kenyon sternly telling him that if he tried to make any noise or
attempted to escape, he would run a hunting-knife through his ribs
without further notice.
By the time the moon rose the party had stumbled out their way to the
mouth of the kloof, and soon had sufficient light to commence the
ascent. Having to go in front and lead the way, Kenyon put Leigh in the
rear to see that none of the bearers lost heart and turned back, giving
the captive into the charge of a gigantic Zanzibari, and warning him
that did he let the man go he should himself be shot like a dog. All
went well until the party was quite two-thirds of the way up the zig-zag
in the rock, when suddenly a commotion arose, and a cry went up that the
prisoner was escaping. Turning angrily round, with his revolver half
raised, Kenyon saw the spy standing on the very edge of the parapet of
rock, with his hands at liberty, and in the act of drawing the gag from
his mouth. On seeing Kenyon turn, the Zanzibari doubtless thought he
was himself about to be shot, and impelled by rage and fear, he sprang
wildly upon the ledge of rock and seized the Spaniard by the throat.
Forgetting the extreme danger of his position, the white man swayed
backwards to strike an effective blow at his sable assailant,
overbalanced, and down they both went, with a horrid scream that rang
out far into the stilly night, and awakened long-drawn, fearsome echoes
in the dark and silent kloof.
One second more, and the horror-stricken band of listeners heard the
united bodies of the ill-fated pair strike with a sickening scrunch on
the rocks five hundred feet below. The whole affair was over in an
instant of time, and even the stem detective was deeply impressed by
this awful dual fatality, and could only beckon with his hand for the
others to follow him upwards quickly and in silence.
In a few moments more the adventurers emerged from the rocky path and
gained the shelter of the bushes, where Leigh and Kenyon quickly
bestowed the men in safe covers, and then posted themselves at a point
from which they could command the other side of the kloof, and so
possibly form an opinion as to how their enemies scaled its heights; for
at a glance the ascent gave promise of providing them with an extremely
difficult, if not impossible, task, and if, in addition to negotiating
this, they had to cope _en route_ with an armed and intrenched foe, the
prospect of success would be extremely problematical.
Leigh had a theory that the slavers were provided with long
rope-ladders, but arguing from the rapid disappearance of the slave
caravan, Kenyon declared that this suggestion would not hold water for a
moment.
Scarcely had Leigh and Kenyon gained their covers than, to their utter
astonishment, steps were heard approaching through the wood in their
rear, and whilst they were making themselves as small as possible, and
breathing a devout prayer that the black fellows might not lose their
heads and try to run away, a band of armed men passed swiftly by their
position and emerged into the moonlight.
The new-comers were about thirty in number, all armed with axe, rifle,
and lasso, and were, with but two or three exceptions, white men. As
they reached the zig-zag pass, the party extended into single file and
promptly disappeared from view down the face of the rock. Until all had
vanished Kenyon scarcely breathed, then Leigh and he turned eagerly to
one another, and hurriedly and anxiously discussed the situation.
Their examination that very day of the side of the kloof upon which they
now stood had been much too complete to admit of their believing that
the men who had just passed them had been all the time lying hid, and
the inference naturally was that these strange people had some peculiar
method of crossing the gorge at its upper edge. Such an apparently
preposterous idea had, of course, not occurred to the pair when
searching the wood, but had the path been at all easy to find they would
most certainly have stumbled across it.
Moving quietly along the back track, the pair cautiously examined every
likely spot, and were about to enter a particularly black-looking clump
of bush, when they were suddenly brought to a standstill by the gruff
challenge of a colossal-looking sentry, who started out from the dark
background of wood and threateningly raised his rifle.
"Halt! halt! and give the password!"
Leigh's hand stole towards his revolver; but men think rapidly in
emergencies like this, and in a moment of inspiration, Kenyon coolly
answered, "_Zero_!"
"_Pass, Zero, and all's well_," grunted the gigantic sentinel, grounding
his arms with a clash, and then, in a theatrical whisper as the pair
approached him, "Mates, you haven't got a drink on you, have you? It's
main cold up here."
Quickly Leigh held out his flask, and as the other was in the very act
of drinking, Kenyon flew at his throat like a cat, and choked him down,
whilst Leigh knelt on his chest, and tried to bind him. Our friends
were both exceptionally powerful men, but this fellow was a regular bull
of Bashan, and it was only after a low whistle had summoned one of their
native guides that the trio got the sentry bound and gagged to their
satisfaction. Next, sending the black fellow to keep watch at the top
of the zig-zag, the pair set to to thoroughly explore the tangled path
which had been guarded by the sentry. A most unpleasant task this was,
too, feeling their way about on the very verge of an immense precipice,
thickly clothed with trees and bush, through which the rays of the moon
cast at intervals a sickly glamour of feeble light and heavy shade.
At last a brief exclamation from Leigh announced a discovery, and
standing by his side, and looking directly across the chasm, Kenyon saw
a curious, and in its way, a striking spectacle. From one side of the
kloof to the other stretched the taut strands of a mighty double rope or
hawser, and from this rope was suspended a small cage, capable of
containing two or three men, the occupants drawing themselves across by
small guide-ropes, whilst the cage moved easily along the hawser upon
wheeled blocks, the whole arrangement being entirely concealed from the
view of anyone, either above or below, by the trees on either side of
the chasm, which at this point blended and interlaced both their foliage
and their branches.
So far good, but as the cage now swung in mid-air over the very centre
of the chasm itself, and had, moreover, an occupant, it was difficult to
see what the next move was to be. It was, however, our friends
reflected, at all events consoling to know that a slash or two with a
sharp knife would effectually dispose of all possibility of their savage
foes attacking them in the rear.
Just at this moment a cautious whistle told Kenyon that danger was to be
apprehended from the direction of the veldt, but at that very instant
the man in the cage, evidently thinking that the signal had been given
for his benefit, commenced to haul upon the rope, and quickly gaining
their side of the chasm, leaped out right into the ready arms of the
pair, who very soon had him securely gagged and tied to a tree, at a
little distance from his fellow. Hurrying back as another low but
earnest whistle reached their ears, our friends found that the slavers
had been seen to surround the tent, and thoroughly explore it; then,
evidently disliking the look of things, they had set out at speed
towards the pass, which they must now be in the very act of climbing.
Carrying off the whole frightened crowd, with the exception of one man
who had shown himself a tolerable marksman and something removed from an
abject coward, Kenyon showed them how to cross the chasm safely and
quietly, and bade them get over at once with all the ammunition.
Persuasion and explanation was, however, of no use at all, and he had to
drive the first batch into the strange vehicle at the muzzle of his
revolver. Then, finding they were quite safe, the negroes promptly
commenced to chatter like so many monkeys, whereupon Kenyon threatened
to shoot them, if he heard another sound, and then returned with all
expedition to Leigh, who had posted himself so as to command the
zig-zag, and had cleverly rolled a big rock into the very mouth of the
channel by which the foe was approaching.
All was now in readiness, and a dead silence reigned. The hush of a
tranquil tropical midnight was upon everything, and all nature was
looking her loveliest under the glamour of the shimmering moonlight.
All at once the stillness was marred by a footfall, and then rent, as it
were, by a furious curse, as the leading slaver reached the top of the
pass, and found the way blocked up. Climbing carefully over the stone,
however, he safely reached terra firma, and was stooping down to remove
the obstruction, when he was angrily hailed in nervous English by
Kenyon--"Here, you dog, leave that stone alone, and go back by the way
you came. Quickly now, and drop that rifle--drop it, I say, or your
blood be on your own head!"
For answer, the fellow fired point-blank in the direction of the voice
(for he could not see Kenyon, who was standing in the shadows of the
wood), and then made for cover, but he never reached it; indeed, he had
hardly moved in his tracks, when down he went, as dead as a door-nail,
being followed a moment later, along the same dark and fearsome road, by
a comrade who persisted in obtruding over the rock rather more of his
person than Leigh was disposed to permit, and ere the thundering echoes
of the rifles had ceased to answer and to mock one another amongst the
surrounding rocks, the remainder of the slavers, having no more stomach
for such work, were in full retreat down the rock, and half an hour
later were seen steering wide out into the south-western veldt, thus
putting entirely to rest any doubts which Kenyon still entertained of
the feasibility of an attempt to scale the opposite cliffs.
Had there been any way of ascending on the other side of the kloof, it
was quite certain the slavers would have known about it, whereas they
had clearly found it necessary to make a very wide circuit in order to
get round the rocks, and thus make their way back to head-quarters.
Sending forward their sable supporters with instructions to get the
prisoners across the chasm, Kenyon led his wondering comrade up the
cliffs to the right, where they suddenly came upon a small lake,
obviously fed by a neighbouring mountain stream.
"Now, old fellow," said he, "just lay down your rifle, and help me to
break up this wall, and assist outraged nature to regain her ancient
rights."
Leigh quickly saw that the water, which came sweeping rhythmically down
from the further heights beyond the hill, had at this point been
artfully turned by a well-made wall, built of rock and broken stone, and
apparently strengthened with mortar or cement, so that the stream,
instead of exercising its own sweet will by zig-zagging down the rock,
as it had done of yore, was wasted on the north-western veldt, where its
advent had probably been largely responsible for the origination of the
marsh, which had already given our friends such a world of trouble. The
wall of the dam, however, proved considerably stronger than Kenyon had
bargained for, so they finally bored a hole in it, and blew the whole
affair up with a couple of flasks of powder taken from the fallen
slavers.
When the smoke of the explosion cleared away, the released water could
be seen bounding over the rocks, and shooting down the narrow channel
with a wild, sweeping rush, effectually closing this method of ascending
the cliffs unless in abnormally dry seasons. A moment later and our
friends could see the stream filtering along its old course across the
veldt, looking like a mighty silver snake as it gleamed and twisted on
its tortuous way, reflecting at every turn the brilliancy of the lovely
crescent moon.
Regaining the edge of the kloof, our friends stepped into the cage, and
were soon hauled across the chasm by one of their men, who was already
quite expert in this singular method of semi-aerial procedure.
On examining the prisoners Kenyon was disgusted to find that they were
both stone dead, the cowardly blacks having killed them, bound as they
were, lest the slavers should get loose and do them an injury. This was
the more aggravating, as Kenyon had fairly counted upon forcing
information of some kind out of the men, and he was, besides, disposed
to think well of the big sentry who had hailed them in English.
However, the men were dead, and it was, therefore, useless regretting
them, but Kenyon inwardly registered a vow to get even with the rascal
who had committed such a brace of infernally cold-blooded murders should
he ever find him out. Then sternly ordering the men to shoulder their
loads, the party set out under the waning moon, directing their steps
downwards and towards the south-east.
