Blight was now within twenty yards of the sheltering rocks. Dare the pursuer use his revolver and stop this headlong flight? The odds were too great, for with the exertion of running his aim would be erratic.
No, he must continue to run and trust to chance that his quarry might be cornered somewhere.
Suddenly Blight stumbled, kicking up a cloud of pumice dust that looked silvery in the moonlight. Two yards he traversed ere he fell headlong in the soft lava, and before he could stagger to his feet his pursuer was almost within arm"s length.
"Give in, you idiot," shouted Mr. McKay, drawing his revolver.
For answer Blight laughed, and, bending low as he ran, he doubled away to the right, where the ground sloped downwards towards a line of irregularly-shaped cliffs. He was crippled. He had twisted his ankle, and everything was in Mr. McKay"s favour.
Unwilling to close with the desperate fugitive, Mr. McKay prepared to maim him with a bullet through his leg; but even as he levelled the weapon, Blight disappeared from sight with a shriek of terror.
Instinctively Mr. McKay threw himself flat on his back, digging his heels into the soft yielding dust; but surely and gradually he found himself slipping towards the mouth of a gaping abyss. The very ground on which he was sprawling was moving. He could hear the rustle of the sand and small stones as they dropped over the ledge into the apparently fathomless chasm.
Desperately Mr. McKay plunged his arms into the sliding sand; but his efforts were unavailing. He was being launched towards the yawning gulf, the horrors of which seemed worse in the moonlight.
Just as he was on the point of slipping over the edge--his heels were already over the abyss--his hand, buried arm"s length in the pumice, came in contact with a piece of hard rock.
Would it hold? he wondered.
Slowly his outstretched arm began to change from a vertical to an almost horizontal position as his body still continued its downward motion. The rock afforded but a slender hold: either the fabric might become loosened, or his hand might be unable to keep up the strain, and then----?
Mr. McKay ceased to struggle. He could feel the sand slipping from under him, streaming past like a solid cataract. So long as he kept quiet he was comparatively safe, but directly he commenced to find a foothold, his peril increased threefold. Yet he knew that every moment his grip upon the small pinnacle that stood between him and instant death was gradually becoming weaker.
In those awful moments of peril he could hear the laboured breathing of his enemy, coming apparently from a great depth beneath his feet.
Blight, then, was still alive, but his gasping breaths sounded ominous.
At length, regaining his self-possession, Mr. McKay put forth a final effort in an endeavour to draw his feet clear of the awful chasm.
Inch by inch he worked himself upwards, against the increasing torrent of sand, when suddenly the rocky ledge was wrenched from its base, and the next instant he was swept into the gulf.
Amidst a shower of dust and stones he felt himself hurtling through the pitch dark air, then everything became a blank.
The first rays of the rising sun filtering through the narrow neck of the inverted funnel-shaped chasm strove to disperse the darkness.
Stretched upon the thick carpet of powdered pumice were two motionless figures, partially covered with the flow of dust that trickled from the open air like the sand of a gigantic hour-gla.s.s.
The head and shoulders of one of the victims were pillowed upon the body of the other, who lay, with arms outstretched, gazing upwards with sightless eyes at the narrow slit of sky that was visible between the lips of the abyss.
Blight had gone to his last account.
Slowly opening his eyes, Mr. McKay blinked stupidly at nothingness for a few seconds, then stretched out his arms. It was the action of a man awakening from slumber. He felt no pain; he had no idea of where he was, or of what had occurred.
With the intention of going to sleep again he turned his head on its ghastly pillow, but on drawing up his arms to compose himself, his head came in contact with the cold face of his companion in misfortune.
The touch acted like an electric shock. In an instant the details of the tragedy flashed across his mind. He stumbled to his feet, but overcome by weakness, he sank once more upon the dust-covered floor.
How long had he been in this hideous deathtrap? he wondered. Was it a night, or many days and nights? Had his comrades searched in vain and had they abandoned their quest and left him to his fate?
For quite half-an-hour Mr. McKay sat and thought, striving to collect his mental and physical powers. He went over the events leading up to the final tragedy--the ambush, the pursuit, Blight"s disappearance, and his own terrible ordeal on the sliding sand. Then he reflected that his trail would be fairly well-defined, and that help must be forthcoming. His watch was still going, so that he knew that it was only the morning following his night"s vigil.
Overhead a dazzling ray of sunlight shone obliquely through the opening, illuminating the shaft-like sides of his prison, but so dead black was the colour of the rock that hardly any light was reflected to the bottom of the pit. He could, in fact, just see his own hands and the grey features of his ill-fated companion.
Mr. McKay groped about the floor. At first his fingers encountered nothing but dust. He plunged his arm up to the elbow in the soft yielding deposit; but nothing solid met his touch.
Fearing that he might be lying on a ledge overhanging a pit of fathomless depth, Mr. McKay extended his field of exploration, making wide sweeps with his arms. Presently his fingers encountered a metal object. It was his revolver.
"At least," he thought, "I can signal for aid."
But on second thoughts he hesitated. Then he remembered his box of matches. Fumbling in his pocket he found the little case, and eagerly, like a miser counting his gold, he pa.s.sed the little sticks one by one through his fingers. Ten--ten priceless matches.
He struck one. For the moment his eyes were dazzled by the yellow fire, but ere it burnt out he made sure of two things. He was not lying on the edge of another precipice; that was rea.s.suring. His second discovery was disconcerting. His trusty revolver was choked with fine dust, and had he discharged it he would have a.s.suredly been injured by the bursting of the barrel.
The match flickered out, and to the imprisoned man the darkness seemed denser than ever. It pressed upon him like a real substance, till he felt tempted to shout in his distress.
By degrees he grew calmer, and staggering to his feet he moved his limbs with extreme caution. To his satisfaction they were still sound, though he was beginning to feel stiff and bruised from head to foot.
The light of a second match showed that Blight was indeed beyond all human aid, so, placing his handkerchief over the face of the corpse, Mr. McKay retired a few steps till a third match became necessary.
He found himself within a few feet of one of the walls of his prison.
The stone, divided by volcanic agency, was almost vertical at the point, though at others it receded so that the base of the abyss was several yards beyond the perpendicular height of the shaft. Close to him was a deep crack in the wall, known by mountaineers as a "chimney."
It might be possible to scale the rock, he thought, but the knowledge that the edge of the shaft was "rotten" compelled Mr. McKay to abandon that attempt. He must wait; yet, unwilling to remain idle, he resolved to sacrifice four more of his precious matches in exploring the immediate vicinity of the chasm.
Keeping close to the wall, Mr. McKay proceeded with the utmost caution, till he reached a yawning cavern that descended abruptly.
For a moment he hesitated, fearing the presence of carbonic acid gas, but on holding the lighted match close to the ground the flame burnt clear and bright.
To his surprise Mr. McKay found his hand resting on the b.u.t.t of a musket. The weapon was lying on the hard, rocky floor of the cave, for here no dust had penetrated. Another match revealed the fact that the firearm was of an ancient pattern, the combined flint and matchlock being of not later date than the end of the seventeenth century.
"By George! This is a find!" exclaimed Mr. McKay.
For the time being he forgot his surroundings, interest being centred in this relic of bygone days.
Then, unwilling to risk using his remaining stock of matches, yet mentally resolving to explore this part of the cavern at the earliest favourable opportunity, he retraced his steps to that part of the chasm that lay beneath the narrow shaft. Here he sat down and waited, hoping for the speedy arrival of Andy and Ellerton.
CHAPTER XXI
THE BUCCANEERS" CAVE
It could not have been more than a couple of hours after Mr. McKay returned to consciousness that the two lads emerged from the forest and gazed wonderingly upon the rock-strewn plain. Not knowing the course of events, they had left Terence and Quexo to guard the dwelling-house against a possible attack.
"Steady, Hoppy!" cautioned Andy, as Ellerton was about to rush towards the spot where they had left Mr. McKay on the previous evening. "I don"t like the look of things. Suppose that rogue has got the upper hand? You would be potted to a cert if you rushed into the open in that reckless style. You work round to the right and I"ll go by the left."
Accordingly the lads, taking advantage of every bit of cover, advanced with the utmost caution towards the little rift in the dark rock where Mr. McKay had made his ambush.
