CHAPTER XV

The Secret of the Mountain

It was well into the afternoon before their gruesome task was

accomplished, and the sun shone far down in the Western sky when they

returned to the camp. They had carried the deceased warriors out into

the sandy tracts beyond the boiling springs. It cannot be said that they

were unduly sympathetic with the slain, and certainly they were anything

but enamoured of their self-imposed contract, but the alternative would

have been extremely disagreeable.

"I have no doubt their brethren would have come for them to-night," said

Bob, "and saved us a good deal of trouble--if we could only have

depended on them going peaceably away again."

"Ay, if," agreed Mackay, dryly. "But their coming would only mean more

funerals, Bob, and as for that, I believe they've been trying to force

that patent door of theirs before now."

He turned and gazed towards the fissure at the base of the mountain, and

at that moment there distinctly came a sound therefrom as of the jarring

of rocks under pressure. They all kept perfect silence for a minute or

two, and again the sound was repeated, but this time it was succeeded

by the sharp rattle of falling boulders.

"That's the top o' our barricade down, I reckon," whispered the Shadow,

reaching gingerly for his rifle.

"They would see us go out into the plains," hazarded Bob, calmly, "but

the smoke of these very convenient boilers has kept them from noticing

our return."

Mackay nodded. "They've got about a solid ton to shift before the door

will swing," he said musingly. "Now I wonder if we should go an' help

them wi' the job or no'?"

"I reckon we has had enough for one day, Mac," answered Emu Bill,

wearily. "Let the skunks work their own passage."

Another rattle, louder than the first, reached their ears.

"'Pears to me they is in a mighty hurry," grinned the Shadow.

Bob rose to his feet. "I'm going to have a look," he said. "Come on,

Jack;" and they tip-toed over to the origin of the disturbances, leaving

their companions apparently deeply and solely intent on bringing the

billy on the fire to a boil speedily.

Mackay had examined the barricade once or twice earlier in the day, and

noticed no change in its appearance, and was convinced that nothing

short of gelignite cartridges could shift their obstruction from the

inside. Bob held the same opinion, but he was nevertheless curious to

see what sort of efforts were being made. Making a short _détour_, they

silently approached the entrance to the underground passage from the

side farthest from the movable rocky slab. The interstice had been

well-nigh filled with diorite boulders, leaving only the top of the

solid panel showing; but when Bob looked now, he was alarmed to find a

considerable shrinkage in the level of the barricade, and though the

noisy echoes of falling rocks were still plainly heard, it was evident

that nothing was rolling down from the top of the pile. Jack drew a

quick breath of anxiety; Bob was perplexed beyond measure, but he made

no sign, and as he looked, behold! the boulder stack was gradually, yet

surely, sinking--sinking apparently into the earth beneath. Then his eye

noticed some slight change in the position of the rocking wall; it was

thrust up somewhat, and gaped widely. The solution of the mystery was

now made clear: the great slab moved upwards as well as outwards, and

the depletion of the pile was taking place from the bottom; the rock

fragments were rolling inwards to the tunnel!

Hastily he beckoned on his companions, and they came forward at a run,

just as the last stone was disappearing from view. But the natives had

now taken alarm. There came a dull thud as the doorway relapsed into its

accustomed place, and then their rapidly retreating footsteps were heard

as they scurried back into the subterranean channel, and the peculiar

tapping of the night before heralded the direction of their flight.

Mackay took in the position at a glance, and an expression of grave

concern settled on his features.

"Their resources are positively marvellous," he groaned in despair.

"It's a vera fortunate thing, Bob, that you werena influenced by my

stupid over-confidence, and came to investigate. We might have been

bowled over wi' their arrows before we had time to lift a rifle." He

continued bitterly to abuse himself while he inspected the now bare

cavity in the mountain.

"I reckon it's a long sight more fortunate that they came along in the

daytime," commented Emu Bill, "which they likely wouldn't have done, if

they had thought we were about. Seems to me, that good Samaritan job o'

ours in planting them nigs nice and comfortable out in the sand has done

us a service right away."

"You've hit it pretty near, Bill," Bob agreed. "If they had done that

trick in the night, we should probably have been wiped out."

"This is a mighty unpleasant climate for us tender lambs, it is," wailed

the Shadow. "There's nary night but what we may wake up wi' a screech

an' find ourselves dead."

"There's one way we can block it for good," muttered Mackay, grimly,

"but I'm no vera willing to do it, for it will block us too, an' I mean

to get inside that mountain before I'm a couple o' days older." He

looked towards the gelignite case, lying near where it had been placed

for safety, and his companions knew his plan at once. "Yes, we may well

shoot down a bit o' the mountain big enough to bar that tunnel safe as a

house, but that wouldn't suit us afterwards."

"If we roll round a few boulders wider than the door itself, that would

keep things pretty safe for a night," suggested Jack; and in the end,

this was the plan decided upon, and for half an hour they busied

themselves transporting the most unwieldy diorite blocks they could

find, and fixing them securely into the cavity. Then they returned to

partake of their well-earned and belated dinner of tea and damper.

The last added proof of the blacks' ingenuity considerably disturbed the

members of the little party. It had been so hard to believe that

aborigines could possibly have constructed the tunnel through the

mountain, but now they were inclined to imagine their savage neighbours

capable of anything.

"I reckon we has got to go slow, boys," remarked Emu Bill, with a

troubled expression; "them nigs don't seem to be the genuine article.

They knows a long sight too much for my liking, they does."

Mackay, too, was obviously concerned. The mysterious tunnel mystified

him; he could not imagine how it had been wrought, but there was

gradually dawning in him a vastly increased respect for the natives who

lived beyond the mountain. That they were different from all other

tribes he had encountered was only too evident. The question was, in how

great a degree did they excel their brethren of the plains? Judging from

his brief experience of them, Mackay's estimate of their powers was far

higher than he cared to admit.

"Of course," he said, in answer to Emu Bill, "if the country on the

other side is what we expect, the natives will be of a much more

advanced class than any we've met before. You see, it's the power o'

environment, Bill; it may have worked marvels here, for a' we know."

They ate their unpalatable meal without much further remark. Then Bob,

who had been pondering deeply over the events of the last twenty-four

hours, showed the trend of his thoughts by asking quietly if any of the

aboriginal tribes had been known to use bows and arrows.

"I never saw, nor heard tell o' such a thing before," grunted Emu Bill.

"In that case," said Bob, "these natives show that they have originated

that custom here, or have retained it from an earlier period, before

the blacks began to degenerate; and, in either case, it proves them to

be an exceptional lot altogether."

"That's just what's bothering me, Bob," admitted Mackay. "We might well

tackle an ordinary tribe, even though we only numbered five against

fifty, but wi' these beggars here, I'll allow we seem to be embarking on

a job that is, to say the least of it, a bit unhealthy. No, no, don't

think I'm gettin' nervous, Bill, but we must calculate the chances

before we start. Bob counted fifty niggers on the hill this morning, so

we've a fair idea o' what we are goin' to run up against."

"Hang it, boss," complained the Shadow; "you doesn't think a crowd o'

nigs is goin' to hustle us back now, does ye? If we kin join their happy

family in the daytime we'll scatter 'em quick an' lively, but the night

gives me the creeps, it does. I can never see the sights o' my rifle in

the dark."

"If we were once on the other side of the mountain," said Jack, eagerly,

"we could soon shift the blacks; it's the wretched old tunnel that keeps

worrying us here."

"Ay, my lad," said Mackay, dryly; "the tunnel is a vera curious

construction for a crowd o' aborigines to make, an' the more I think

about it, the more puzzled I become. I was going to suggest that Bill

an' me should force the passage in the morning, while the three o' you

waited out by the camels in case o' accident."

"I'm right wi' you there," cried Emu Bill. "I reckon it ain't safe for

these here young 'uns to come along wi' us first----"

A storm of protest greeted his words, and Bob turned to Mackay

reproachfully.

"I know what you mean," he said; "but neither Jack nor I will leave

unless we all leave together, so that if anything happened to you we

would not escape in any case. Isn't it far better to make the most of

our strength instead of dividing it?"

"Well, well, perhaps you are right," returned the big man, hastily, as

if annoyed at his own fears; "but we'd better wait until morning before

we start the circus. Like the Shadow, I prefer to meet the natives in

daylight, and anyhow, we're a' needing a sleep to-night, so we'd be

better to turn in early and get up by sunrise. It should take us a good

half-hour in the morning blowing out that tunnel door for a start."

Certainly nothing further could be done on that day, for the darkness

was already closing in, and each one of the party was weary and tired

from lack of sleep. So shortly afterwards they lay down in their

blankets, though not before a searching examination had been made of the

new barricade erected at the entrance to the subterranean passage, and,

in spite of the known dangers surrounding them, they slept soundly, each

taking a two hours' watch in turn. It was well after midnight when Bob

awoke for the first time, and at once his ears caught the strange

tapping in the mountain which had first heralded the approach of the

natives on the night before. He aroused himself immediately, and saw

Mackay, who was on guard, listening to the ghostly echoes intently.

Slowly they seemed to pass along the base of the hill, then all was

quiet. Bob got up and joined Mackay, and together they walked softly

towards the fissure, and there in the dull light they could vaguely see

the great boulders move as if under pressure from beneath, but though

they watched for fully ten minutes in silence, the barricade remained

intact. Jack's scheme had worked admirably. Then Mackay turned on his

heel with a loud laugh.

"It's just as well to let them ken we're here, Bob," he explained; and

the sound of scurrying footsteps which answered him from the concealed

passage showed that the natives had thought fit to retire once more.

Then again the peculiar tapping issued out dully from the great rock,

continuing for nearly a minute before it faded into the stillness of the

night.

"Well, what do you make of it, Bob?" asked Mackay.

Bob did not hesitate a moment. "The passage must lead for some distance

along the face of the mountain," said he. "But why these strange sounds

are heard every time the blacks come along, I cannot say."

"Man, Bob," laughed Mackay, "that's vera easily explained. The tunnel

must be dark, of course, and the warriors have to guide themselves along

the passage by feeling the walls wi' their arrows or clubs as they go.

It just struck me that that was the reason o' the uncanny noises when I

heard them come along there to-night. Simple enough, isn't it, Bob?"

"I'm glad there is nothing approaching the supernatural about it,

anyhow," replied Bob, soberly. "The echoes seemed to ring in my ears

like a knell of doom."

He shuddered as he got back into his blanket. The others were awake by

this time; but when they learned that an ineffective attempt had been

made to destroy the barricade, they chuckled in rare good-humour, and

went off to sleep again. The remainder of the night passed without

alarm, and the morning broke, calm and serene, over the little camp,

which awoke to life with renewed vigour after its peaceful slumber.

Breakfast was soon over; then a hurried council of war was held to

reason out the best plan of action. Emu Bill was in favour of inserting

a heavy charge of gelignite in the rocking panel which had defied their

gentler efforts on the preceding day; and Jack and the Shadow supported

this proposal vociferously. Mackay, however, though he had at first

advocated this drastic action, now seemed reluctant to carry it through;

and Bob, too, though he did not say much, was evidently pondering over

some other and better scheme, which he at last broached hesitatingly.

"If the passage runs parallel with the face of the mountain for twenty

or thirty yards," he said, "it strikes me that if we made a fresh

entrance to it as far away from the old one as possible, we could

deceive the natives most completely, and perhaps provide a means of

escape in an emergency."

"I don't quite catch on," grumbled Emu Bill. "I'm hanged if I see what

difference it should make; an' we doesn't know how far we'd have to dig

into the blasted rock afore we hit the tunnel--if it's where you say."

Mackay took up a pick, and, proceeding along the base of the mountain

away from the fissure, struck at the rocky wall repeatedly, with the

result that a deep, hollow rumbling issued forth at each stroke, until a

point had been reached some thirty yards distant from the tunnel

entrance, when only the solid diorite formation gave back the sound.

"I calculate we'd have less than five feet to drive, Bill," said he.

"About a couple o' long shots in from the top would do it. You can

trace the passage as plainly as if you were looking at it. I don't know

what the idea was in making it like a boomerang; but we'll soon find

out. Now, Bob, you're better at explaining than me. Try an' convince

Bill o' the advantages we may derive from making a new hole into the

mountain."

"I reckon I can see it all right," cried the Shadow. "Oh, it are a

daisy----"

"Shut up, Shad," growled Emu Bill. "Now, Bob, for any sake, tell me your

plan. Of course I'm with you, whether I understand or not; but, blow me

if I can see the force o' doing extra work in the niggers' mountain fur

nothin'."

Then Bob endeavoured to elucidate the ideas which had been taking shape

in his brain all through the night, since Mackay and he had come to a

conclusion as to the origin of the warning sounds and the proximity of

the passage for some distance to the outer air.

"If we don't tamper with the old door, boys," said he, earnestly, "we

can block up the hole we make by some bagging, and so will always have a

chance of escape if the natives are too many for us. They will guard

their own entrance only, for they probably will never see ours; and it's

just as well to take precautions. The darkness of the tunnel will help

our plan; and if we succeed without having to trouble about getting

back, so much the better----"

"And there are a few more arguments in favour o' the scheme, Bob," added

Mackay; "but we may see the excellence o' them later."

"But they'll hear us firing the charges, won't they?" said Jack.

"They heard us doing the same thing yesterday," answered Mackay; "an'

they saw us too, so it's no vera likely they'll trouble us to-day. But

if we put the drill-holes in deep enough, and give the powder plenty

work to do, there shouldna be much noise--in fact, I doubt if they'll

hear it at a'."

No time was lost in making the experiment, and the long steel drills

were quickly grinding their way through the hard outer casing of the

rock as nearly as could be judged opposite the place where the passage

took an abrupt turn inwards. And now the mining knowledge of Mackay and

Emu Bill made their work comparatively easy; they knew exactly the

correct angles at which to drive the drills so as to obtain the best

results when they loaded the holes so made with the deadly explosive.

Steadily they laboured at their task, Bob, Jack, and the Shadow

assisting at intervals, but more often engaged farther out in the open

making a goodly appearance for the benefit of the natives, should they

chance to be watching, and thus drawing attention away from the great

work in hand. For a full hour Mackay slogged at the steel with his

mighty hammer, then gradually the borings extracted from the deepening

hole grew lighter and redder in colour, and the drill sank inwards

rapidly.

"That's a new formation we've struck, Bill," said he, pausing to examine

the edge of his tool. Then an exclamation broke from his lips. "We're

chippin' through a gold lode!" he cried; "and it's so rich that the

drill clogs in the metal."

"I reckon there's nary nig'll shift us from here now," said Emu Bill,

examining for himself the gold grains exposed. "I means to see the other

side o' this here mountain, or bust. I reckon there must be oceans o'

gold an' di'monds over there."

At this stage Jack called out warningly, "I see old Nebuchadnezzar on

the top of the mountain again."

"It's the same old nig that we didn't shoot," exclaimed the Shadow;

"an', blow me! if he ain't goin' to throw stones at us."

The tall figure on the summit had certainly attempted to throw something

down; but it caught on a jutting rock overhead, and bounded thence into

the rising vapours of the hot springs. Once more he appeared to cast

some projectile into the air; but if he did, it did not reach the ground

in the vicinity of the anxious party beneath. Then again a visible

missile came hurtling down; but it fell wide, much to the Shadow's

satisfaction.

"The old fool can't throw stones for nuts!" he cried delightedly.

"I don't think he'll hurt us much," said Mackay, with a laugh. "Let him

play away, Shadow, if it amuses him; it doesn't do us any damage."

And the individual aloft continued his strange pranks for some time,

though in no one instance did the stones he threw alight even moderately

near; then he vanished as suddenly as he had come.

"I think we're about ready for firing, Bill," said Mackay, shortly

afterwards. "We'd better hurry up, too, seeing that there does not seem

to be any one about to watch in the mean time."

The drill had been driven over eight feet down, at an angle of somewhat

less than forty-five degrees, and Bob, making a rough calculation,

considered that its extremity was at least four feet away from the

surface of the rock in a straight line.

"We'll give it twenty-five cartridges, I think," mused Mackay, "an' the

shock o' discharge should burst at least another foot inwards."

"I reckon something's bound to shift," murmured Emu Bill, as he deftly

prepared the charges, and inserted the long fuse.

Bob watched the last operation with quiet interest, but not so Jack and

the Shadow. They suddenly pranced off towards the cooking utensils by

the fire, and began to drag them back out of range.

"Tea and damper is bad enough," groaned the Shadow, tenderly secreting

the only two billy cans the expedition possessed; "but damper without

tea would be howlin' starvation, it would."

"You doesn't need to worry, Shad," grinned Emu Bill. "There won't be

much o' a scatter here."

And he calmly applied a lighted match to the end of the fuse, and stood

for almost a minute, listening to its sputtering as the fire crept

slowly down towards the gelignite, before he turned away. Another

minute, two minutes, three minutes passed.

"I'm afraid we've had a misfire, Bill," said Mackay.

But just as he spoke the base of the mountain seemed to quiver and burst

forward, then came a dull report, and when the smoke cleared away, a

giant crack showed in the rock, but otherwise no evidences were left to

indicate that a powerful explosive had been at work.

"That's hard lines," said Emu Bill, stepping forward. "It might have

shifted that chunk o' iron out o' the road, anyway. Now we'll need to

begin all over again."

"I'm no so sure o' that," answered Mackay, waving his hat in the rent

created in order to dispel the clinging white fumes, which obscured all

vision.

Then it was made apparent that it was no mere crack in the formation

they gazed upon. The force of explosion has not only cleft the rock, but

had thrust it almost a yard forward in one unbroken mass, and at the

bottom of the chasm thus made a vague blackness appeared, the blackness

of a void. Mackay bent down his head eagerly, but hastily withdrew it

again; a rush of heavy damp air, stifling and odorous, had come with a

gust in his face.

"I reckon them powder fumes'll make you feel pretty bad," sympathized

Emu Bill. "Just give the smoke time to clear, Mac, an' then we'll put in

another shot."

"There's no need to do any more work here, Bill," answered Mackay,

recovering himself. "We've broken right into the tunnel first pop! There

it is, too, as natural-looking an entrance as you could wish to see, wi'

a door--if we could move it--that weighs five tons if it weighs a

pound."

Eagerly they all clustered round to look; and now that the atmosphere

had grown less clouded, the dark shadows of the cavern below were

plainly discernible. Bob gave a sigh of relief. At last the secret of

the mountain was to be revealed.

"Well, I reckon I'd better get down an' prospect round a bit," said Emu

Bill, hitching up his nether garments preparatory to scrambling down

into the uncertain depths.

"Let me go first," urged the Shadow. "I'm the lightest, and it wouldn't

hurt me much if I did go down a bit further than I expected when I let

go the edge."

"We'll lower a rope wi' a stone on the end o' it before any one goes

down," said Mackay, firmly. "We've got to engineer this funeral vera

cautiously, my lad, an' mustna go bouncing ourselves into difficulties,

as if there was a good fairy waiting by us every time to pull us out o'

them."

A rope was speedily forthcoming, and fastening a fragment of rock to the

end of it, Mackay carefully allowed it to descend. It came to a

standstill in good time, however, showing that the bottom of the passage

was barely three feet below the point where the rent had entered its

wall. Mackay quickly proceeded to adjust the rope so that its extremity

dangled just on the edge of the yawning gap, then he made it fast on the

outside by coiling it several times round the top of the sundered rock.

"A man could pull himself out in a hurry by getting something to hold on

to," he remarked, "an' it's just as well to be prepared."

This operation completed, Emu Bill wriggled himself down through the

narrow opening, and holding on to the guiding-rope, quickly disappeared

from view, while his companions on the surface waited expectantly for

his report on his surroundings.

"Well, an' what do you make of it, Bill?" demanded Mackay, when the

tension on the cable had slackened.

"I can't see a single thing," came the response. "It's dark as--as

Hades, an'--howlin' blazes! but it does smell."

Without a word Mackay slid down beside his complaining comrade; the

Shadow followed, then Jack, and lastly Bob squirmed down beside them.

All was dark and oppressively gloomy in the strange passage, and the

thin streak of light from the opening they themselves had made, only

served to intensify the utter blackness which prevailed. They stood for

a full minute without speaking, their ears alert for the slightest sound

which might warn them of danger; but all was silent as a tomb.

"Now, boys," whispered Mackay, "we'll have a look at the inside o' that

other doorway before we go any further." He led the way, staggering and

stumbling, and Bob, following at his heels, became conscious that the

floor of the tunnel was extremely muddy and wet. After a few steps

Mackay paused. "I've got a bit o' candle in my pocket," he said; "I may

as well strike a light."

The match spluttered feebly in his hand for a moment, and then went out,

but on a second attempt he succeeded in getting the candle alight, and

though it burned with a dismal blue flame, it illuminated the rocky

cavern sufficiently for the adventurers to observe its structure.

They stood in a longitudinal chamber about eight feet high, and barely

four in width. The roof fairly scintillated with beaded moisture, and

the dank, cold walls were adrip with ooze. The bottom of the chamber, as

they had already discovered, was a soft and clinging clayey formation.

Mackay's trained eye immediately grasped the significance of the scene.

"This is a most extraordinary thing to find in the heart o' Australia,"

he said. "It's a tunnel driven through an enormous gold lode, an' it's

vera evident that the men who made it knew almost nothing about mining,

for the ore hasn't been stripped either to the hanging wall or foot

wall. It's just as if a blind gap had been dug into the country where it

was softest."

"I see a nugget shining in the roof," whispered Jack, pointing to a

yellow splatch showing overhead.

"Ay, my lad, an' I can see several more," said Mackay, surveying the

exposed stratum in bewilderment. "It is a wonderful mine, without a

doubt, but what on earth the natives do with it is more than I can

imagine."

He moved onwards once more, and then he halted suddenly, and held the

candle aloft. The passage had come to an end; before him stood the huge

stone panel which had first barred their entrance; at his feet gaped a

deep, pit-like cavity.

"Come close up here, Bob," he said quietly. "Come an' have a look at

this arrangement o' things; primitive but effective, eh?"

Bob gazed at the sight before him in absolute wonderment. The great

stone which marked the end of the chamber stood upright on an egg-shaped

base; it appeared to be formed like a rude and bluff wedge, the wider

extremity protruding outwards, where, as had been seen, it flanged

neatly on to the main rock from which it had sprung. But it was not its

shape that surprised Bob: a massive bar of some gleaming metal was

welded into it fully halfway up its height, and from this U-shaped bar a

rope of extraordinary girth stretched taut into the depths of the pit,

where it could be seen attached to a ponderous mass of diorite rock,

which hung from it like the weight of a giant clock.

"It must take more than one man to open that door," murmured Jack.

"They probably always come in force when they use this passage," mused

Bob; "and see, I suppose that arrangement is for keeping the stone bent

over when they are out?"

He pointed to a short and stout log lying near, which had apparently

been used for preventing a quick rush back of the weighted panel when

the warriors had gone out on the night of the conflict. Mackay stepped

gingerly across the intervening shaft, and shone his light into its

unsavoury depths as he did so.

"I see now where our boulder barricade dropped to," he said; "but I can

see also that they can never move our present obstruction in the same

way, the big blocks outside will stick them, no matter how they try."

Emu Bill now tried to find his speech. "How in thunder is we to account

for the rock prizing open wi' us at first?" said he. "I can't understand

this here concern yet, I can't."

Bob pointed downwards to where the wall of the pit was deeply scarred

and dented.

"Likely enough the weight caught in the side," he said, "and so eased

off the tension considerably."

Mackay, who had been keenly scrutinizing the rope and the stout bar in

the stone to which it was connected, now lifted his head.

"The rope is made o' a grass which doesn't grow on our side o' the

mountain, boys," he said; "but the bar is fashioned out o' a metal which

is known to all of us, though we've never managed to possess it in

sufficient quantities to throw away on a job like this, where simple

iron would be far stronger and better in every way."

"Why!" exclaimed Emu Bill. "You doesn't mean to say that they've stuck a

chunk o' gold in that there stone, does ye?"

"I just do," answered Mackay, wearily. "Now, I think we'd better get out

and think over things for a bit. Two or three shocks o' that sort would

just about destroy my nervous system altogether."

"But you ain't goin' to leave that bonanza in the rock, surely?" cried

the Shadow. "Let me get one tug at it, boss, I'll pretty soon yank it

out, I'll----"

But here his companions gently but firmly led him away.

"There's bound to be lots more of it lying around," said Jack,

soothingly, as they retraced their steps.

When they reached the exit the light of the candle showed them that the

tunnel here swung off to the left at a right angle, and at this point

the passage was considerably wider than they had at first judged,

probably owing to the difficulty the natives had experienced in making

such a sharp turn. But the eye could distinguish nothing beyond the

radius of the feeble illumination; all was oppressively murky and damp

and repellent.

"That's our road, boys," said Mackay, pointing with his candle into the

gloomy cavern which led into the heart of the mountain. "But before we

start on our journey we'll get out an' make our final arrangements, an'

change our wardrobe to suit the situation."

In a few minutes they were all on the surface once more, eagerly talking

over their prospects, for, strangely enough, the dangerous aspect of

their projected journey through the mountain was for the moment lost on

them, so completely had the glamour of the golden tunnel exercised its

subtle influence. Mackay, however, quickly regained his control.

"We must remember, boys," he cautioned, "that we have no ordinary

natives to contend with, an' before we leave this camp it will be

necessary to attend to some details which may be helpful to us

afterwards."

"What would you suggest?" asked Bob.

"In the first instance," Mackay replied, "we should hide the camel-packs

containing our provisions. We can easily do that out among the sand on

the other side o' the springs. It won't take us half an hour

altogether."

"But what about the camels?" interjected Jack.

"They are a good distance away, my lad, an' they're no' hobbled. They'll

just have to take their chance; but I don't think there's much risk in

that direction, after all, for Misery can't stand the sight o' a nigger,

an' if he bolted, the rest would follow, an' we could track them up

afterwards just as I had to do before in this same district."

It was yet early in the day, and though Emu Bill was loath to delay

their tour of discovery even for five minutes, he was brought to see the

wisdom of Mackay's advice. Within half an hour the camp had assumed a

bare and desolate appearance, only the heavier mining implements being

left at the base of the mountain. Then they gathered round the cleft in

the rock, and hurriedly prepared for their work of subterranean

exploration. It had been agreed that the party should don the robes of

the deceased warriors in order to lessen the chances of detection should

any natives be encountered while traversing the mysterious passage, but

now they saw that whereas there were five persons to transform into

savages, there were but four of the long furry coverings, although the

feathered decorations for completing their sartorial equipment were more

numerous than necessary.

"I believe I saw one o' them 'possum robes in the pit, aside the hanging

rock," said Emu Bill, reflectively. "I'll go an' get it in a jiff."

He disappeared into the recess immediately, and Bob heard him feeling

his way back towards the old entrance, muttering and grumbling against

the awkward nature of the dismal, muddy track at each floundering step.

Then for a brief space all was still.

"A bit o' charcoal rubbed over the face an' neck will make us more

nigger-like, I'm thinkin'," laughed Mackay, as he surveyed himself with

rueful gaze.

It was no sooner said than done. Jack rushed over to the smouldering

fire, and came back with a handful of charred embers, and with these

they smeared their faces and hands plentifully.

"An' I reckon we won't want our boots," grunted the Shadow, discarding

his almost soleless shoes, and rolling up the legs of his much-frayed

nether garments.

"That's right, Shadow," said Mackay; "you make a grand nigger, an' I

only hope I don't mistake you in the dark for a real warrior, an'

slaughter you in error."

Bob and Jack, when they had finished their toilet, looked their part to

the life; but when Mackay's towering bulk was arrayed and besplatched to

his satisfaction, he seemed the most fearsome object imaginable, a

formidable-looking savage indeed.

"Now I wonder what's keeping Bill?" broke out Jack, impatiently. "This

rock here is burning my feet terribly."

"He'll be tryin' to wrench off that bit o' gold from the big stone,"

remarked the Shadow, with assurance. "I reckon I'll go down an' help

him."

"You'll do nothing o' the kind," said Mackay, firmly, laying a

restraining hand on the youth's shoulder. "We've got something else to

do in the meantime, my lad. Bill will be gropin' in the dark for that

nigger dress, an' he'll be here in a minute."

The Shadow's feeble smile at being intercepted in his desire to possess

the treasure he so much coveted looked so malevolent on his besmeared

features, that Jack could not forbear a hearty laugh. Then Bob gave a

gasp of dismay.

"I can hear natives coming through the passage!" he said. "What are we

to do about Bill?"

The vague echoes of shuffling movements were now quite plainly heard,

and still there was no sign from Emu Bill; probably he had not yet

become aware of the ominous sounds, or perhaps he was, as the Shadow had

suggested, too much engrossed with a congenial task to grasp their true

significance. With a forceful expression on his lips Mackay insinuated

his muscular form into the gap, and just at that instant a band of

savages swept by him so close that they almost touched him. Then only it

seemed that Emu Bill became aroused to his danger. A hoarse snarl of

rage rang along the passage, and the sounds of a silent scuffle came to

Mackay's ears as he stood motionless by the exit. With a stifled groan

he pulled himself up, just as the warriors had evidently accomplished

their work.

"Have they killed him too?" whispered Jack, nervously.

Mackay did not trust himself to reply. He motioned Bob to hand him his

rifle, and he was sliding back into the passage with a vengeful rage in

his heart when a stentorian call from Emu Bill made him pause.

"I'm not dead, boys," he cried, "but they've got me trussed up like a

prize fowl, an' I don't know what they're goin' to do wi' me. Block the

light, or they'll see where I came in, an' don't try to save me now, for

there's over a score o' the skunks. It'll be all right, boys, all right.

Ye are a pack of miserable, sneakin', howlin' gorillas----"

The last phrase, which was continued at some length, was obviously

destined for his captors as they bore him along. It was evident that

Bill had suffered no serious hurt at their hands, and his warning showed

that, even under such exceptionally trying circumstances, he was not

unmindful of the welfare of his comrades, who would assuredly have been

overcome had they descended to his assistance. The bushman's chivalric

self-abnegation however would not have deterred Mackay from taking long

odds at a work of rescue, but in the gloom of the cavern such action

would have been futile, or perhaps worse, because any shots fired at

random might just as easily kill Emu Bill as any one else, and the

resultant chaos could only end in one way. So Bill was led away by the

savage band, who gave vent to their satisfaction by sending forth

shrill, unmusical shouts, which rang through the vaulted chamber like

the cries of demons in torment. They passed by the gap in the wall which

Mackay's bulk covered without a moment's pause, and marched slowly on

into the heart of the mountain.

When at last all discordant sounds had died away, Mackay aroused himself

with alacrity; but when his gaze fell upon the despondent countenances

of his companions, he could not forbear a smile; their dusky aspect and

warrior-like trappings agreed ill with their sorrowful visages.

"Now, my young savages," he cried, "try an' look less miserable. We've

got to get through the mountain somehow now, for I won't leave Bill over

there on his own. See that you've got plenty of cartridges, my lads, an'

let us go."

"Poor old Bill!" murmured the Shadow, sadly. "It was that darned chunk

o' gold that did it, I reckon."

"Now that they've found some one in the tunnel," said Bob, wearily,

"they'll most likely come back to set a guard over the door; and when

they find it won't open, they'll look around until they get this

entrance, so that we'll be blocked completely from getting back."

Mackay was already halfway into the passage, but he climbed out again

quickly on hearing Bob's words.

"You're quite right, Bob," said he, "an' there's only one thing to do

before we start on Bill's trail. I don't like the idea o' it, but I

believe it's the best plan."

They all hurried over to the barricaded entrance of the fissure, and

straightway began to pull aside the great rocks they had placed there so

carefully the night before. Already Mackay's forethought in hiding the

stores of the expedition was about to bear good fruit. If the blacks

came out now, as they undoubtedly would, they would find nothing to

destroy of any importance, and it was extremely unlikely that the

natural-looking crack in the rock further along the hill would receive

their attention; and, even if it did, the adventurous four would run no

more risk than if they had left the barricaded crevice intact. Mackay

calculated much on the blind, unreasoning ardour of the blacks.

"They won't come out in the daytime if they think we're about," said he,

grimly, "and in the night they can see nothing, anyhow, though I hope we

haven't to dodge about in that passage for such a length o' time."

Jack now bethought himself of a brilliant scheme whereby the purposes of

the free exit would be served without danger of the blacks profiting

much thereby. He found poor Never Never Dave's empty rifle lying near,

and this he carefully propped up by the aid of several boulders with the

long barrel directed fairly at the great stone door.

"They'll think there's a man behind the gun," said he, chuckling in

boyish glee, "and whenever they open the concern they'll pop back again

mighty quick."

"It's a vera excellent idea, Jack," approved Mackay. "Now, surely, we

can go our way in peace."

They returned to the rent in the mountain which the explosive had made,

and without further hesitation stepped down into the depths below, and

Mackay, who was the last to descend, dragged with him a number of empty

flour bags with which he effectually screened the little light which

filtered between the sundered rocks. All was still in the passage as

they felt their way cautiously forward, hugging the walls for guidance,

their bare feet plashing in the oozy mire. Mackay and Bob led the way,

each pressing against the opposite sides of the passage for support.

Jack and the Shadow followed, more secure of their steps, knowing that

the way was proved before them. On, on, they struggled; Bob would have

dearly liked to light a match, but that would have been extremely

foolhardy at such a critical juncture of their pilgrimage, as it would

betray their presence to any aboriginal who might happen to be lurking

near.

Already they seemed to have been an age in the stifling cavern, though

but a few minutes had elapsed since their entry. The tunnel, as nearly

as Bob could judge, had continued on a straight course, but it was hard

to estimate with certainty how great a distance had been traversed.

Suddenly Mackay stopped and clutched Bob's arm in a vice-like grip.

"There's a hole o' some sort at our feet," he whispered, as the lad

stumbled backwards.

Bob put forward one foot gingerly, but it met with no resistance;

assuredly a dangerous void intervened in their path. In vain they sought

across the full width of the passage for a foothold; not an inch of

solid ground remained, and the clayey particles dislodged by their

essaying footsteps fell down into an unknown depth, and sundry gurgles

and splashes echoed back as they reached the bottom.

"There's no scarcity o' water there," remarked Mackay; then he felt over

as far as he could reach with his rifle, and at the utmost limit of his

stretch something hard interposed. "It's just like a shaft cutting down

through the lode," he murmured; "but how the beggars get across it beats

me to understand."

"We could take it at a jump, I think," suggested Jack.

"I'm afraid we'd slip into the water if we tried, my lad. It's no' easy

gettin' a firm footing in this clay for a start. No, I think I'll throw

the Shadow across first an' he can steady us from the other side."

"Say, boss," said that individual, plaintively, "I ain't no flying

machine or human bullet. I reckon my tender bones won't get damaged so

much if I jump----"

But while they stood thus deliberating as how best to surmount the

difficulty, the dreaded sound of approaching natives fell dully on their

ears. The Shadow uttered a stifled groan and his rifle-lock clicked

under his impetuous fingers. Jack gave a faint whistle of dismay, and

Bob calmly drew and cocked his revolver. Mackay stood unmoved, straining

his eyes into the gloom; then he gently pressed Bob back close to the

wall.

"Hug the side," he whispered; and each one crushed hard against the

slimy rock, and waited.

Pat! pat! pat! came the unwelcome echoes, accompanied by an occasional

splash, as the oncoming band floundered in the mire, and the direction

from which the disturbance came was away decidedly to the left, although

it was speedily altering to a point straight ahead. Bob noted this fact

carefully, despite his alarm.

Nearer and nearer the unseen band advanced until but a few yards

separated them from the yawning pit. Bob held his breath. Would they

walk blindly into it? Had they miscalculated its position? He felt

Mackay's hand press lightly on his shoulder as if to give him

confidence, and he marvelled at its steadiness, and braced himself for

the encounter he felt sure was about to begin. He could hear Jack's

heart throbbing under the severe tension of the moment, and the Shadow's

quick breaths indicated how trying was the strain even for that

iron-nerved youth. But now came the crucial moment; the foremost savage

shrieked out a guttural word of warning, as it seemed, and stopped,

apparently on the edge of the chasm. A second later and his feet

alighted with a sharp, sliding sound close opposite Bob, and with a

recovering effort he passed on. He was followed immediately by another

and still another warrior, whose arrows rustled in their hands as they

cleared the gulf. If one of them had slipped there could have been

little hope of escape for the intrepid quartet, for assuredly the

slightest stumble would have sent him right into their arms. But no

disaster of the kind occurred, each wildly-leaping figure arrived safely

on the slippery floorway beside them and lunged forward with the

momentum of his flight, and in this way fifteen warriors passed and

proceeded on their way; then all was quiet again.

Mackay broke the silence. "That was a close shave, my lads," said he,

coolly. "Now, I wonder if any of you noticed how they got across so

sprightly?"

"I reckon they jumped," grunted the Shadow, "an' I is mighty pleased

they jumped so well."

"It would be a good jump," whispered Bob; "but they cleared it too

easily without a run."

"I think I'll risk lighting a match," said Mackay. "There's a bend in

the tunnel straight forward a bit, so nothing can be seen past that, an'

the niggers that have passed will probably be dodgin' the barrel o'

Never Never's rifle by this time."

A howl of terror from that extremity of the tunnel almost verified his

surmise. Mackay calmly struck a match, held it aloft for an instant, and

blew it out hurriedly, but in that fleeting moment Bob caught sight of a

stout rope suspended from a beam directly over the pit, and he also

observed that at this point the roof of the tunnel was considerably

farther above them than it had been at the start of their journey.

Evidently, greater work of excavation had been done at this part of the

golden lode. Mackay groped forward and seized the rope, gave it a tug to

test its strength, then swung himself lightly across the obstacle which

had delayed them so long. Bob went next, then Jack and Shadow trusted

their weight to the flying trapeze.

"They might just as well have put a log or two across that shaft,"

murmured Mackay.

"Yes, I reckon it would be a long sight handier for visitors," agreed

the Shadow; and they plodded on once more. Slowly, slowly, they

advanced, and now Bob became conscious of a growing change in the

atmosphere; it was surely becoming less and less stifling, and the

overpowering odours which had been with them so long were gradually

dispelling. Round to the left bore Mackay, and Bob followed, wondering

vaguely if the light of the outside world would soon burst upon them,

but no sign of lessening gloom cheered them on their altered course.

Another few minutes passed, then Mackay stopped with an exclamation of

surprise, the solid wall had reared up before him; they had been

following a blind drive!

"I'm certain I heard them coming round this way," he said, feeling with

his hand across the barring rock as if in search of some clue to the

mystery.

"We may have taken a wrong turning," suggested Bob, much perplexed. Then

he missed Jack beside him, and the Shadow too had disappeared. "They're

both gone," he muttered anxiously.

"That shows there must be a branch off somewhere," said Mackay,

cheerily. "They must have been hugging the right wall while we clutched

on to the left. We'll hang in to the right going back, Bob, an' we'll

get back on to the main passage."

And back they went, striving vainly to quell the rising fear in their

hearts, for both were more alarmed than they cared to admit over the

absence of their comrades. At last they reached the awkward turn, and

almost, at the same moment, floundering footsteps were heard approaching

from a new direction, almost continuous with the line along which they

had just returned. Not a word was spoken, and the two stood motionless

at the junction of the ways waiting for some sign which would indicate

to them whether their near neighbours were friends or foes. And even as

they stopped, the sounds which had attracted their attention ceased

abruptly, and for a short space all was still. But it was only for a

short space; away back in the distance the harsh cries of the returning

warriors thundered along the passage. Apparently they had not ventured

out beyond the mountain, and that knowledge was satisfactory enough, but

what of the new danger which threatened by their retreat? There was no

deep chasm to distract the savages' notice at this point. On they came,

their unmusical voices raised in a droning chant which might equally

well have expressed joy or regret so far as Bob could make out. Then it

suddenly struck him that they would imagine the white invaders of their

domain to be still outside, despite their capture of Emu Bill in the

well-guarded precincts, and were duly rejoicing in consequence. Over the

watery pit they swung, nearer and nearer they drew. Then out of the deep

gloom opposite clicked the hammer of a rifle, sure evidence that it was

Jack and the Shadow who waited near. But it was too late now to speak,

and the way of safety was unknown. Mackay and Bob pressed backwards

whence they had last come, and the foremost savage almost brushed up

against them as he felt for the wall. Bob's hand was on the trigger of

his revolver ready to fire, but the warrior with a grunt passed over the

entrance to their retreat, and stumbled onwards into the unexplored

darkness ahead. And in this way the invisible band trooped by, nor did

they once pause to investigate the openings on their left or right.

When they had passed out of hearing, a cautious voice whispered hoarsely

from the darkness--

"Is ye there, boss? Shout out quick, for I is goin' to shoot."

"Keep your finger off that trigger, you nervous young rascal," responded

Mackay, sternly; and at the words the lost pair issued forth from their

hiding, and rejoined their companions.

"It was all owing to our following the right hand wall," Jack hastened

to explain. "We didn't know you weren't with us until we came to the

end."

"Another blind drive," muttered Mackay. "This is getting very confusing.

It's just as well the niggers came back again to show us the way."

"And it was just as well they came back while we were off the main

track," said Bob; "otherwise we might have had trouble."

Then they moved on along the middle track which they had been fortunate

not to find at first, and for the space of several minutes not a word

was spoken. There was no doubt about the hazardous nature of the mission

on which they were employed; and Bob smiled grimly to himself as he

reckoned up the chances against them, yet, strangely enough, each

member of the expedition seemed in no wise to consider his own safety,

and was fully determined to meet the best or worst that Fate had in

store. A period had come in their lives when the call of the Unknown was

irresistible; and had this for a moment failed them, the firm desire to

rescue Emu Bill from the clutches of the savages would have sent them

steadily onwards, recklessly ignoring the cost, for the wanderer's creed

is simple and sincere--he may never forsake a comrade in deadly peril.

Their progress was painfully slow, for they knew not what obstacles

might lie in their path, and probably it had been a miscalculation of

their own pace that had led Mackay into error, when he turned into the

drive along which he fancied he had heard the blacks approaching, for

now the tunnel was distinctly curving to the left, and the occasional

rush of fresh air which swept into their faces told them quite plainly

that they were on the highway to the outside world. Slowly, too, the

darkness began to merge into a gloom less and less profound, until the

floor and sides of the cavern they traversed became dimly discernible.

"We won't be long now, my lads," encouraged Mackay.

"I is gettin' mighty nervous," murmured the Shadow, cheerfully. "I

reckon I'll go back home. This ain't no place for a youth o' tender

years, it ain't."

Bob laughed quietly at his companion's happy pessimism, and was about to

make a reply when a faint buzzing sound in the unseen distance ahead

drew his attention. Mackay, too, had heard it, and he stopped for an

instant to listen more intently.

"What is it?" asked Jack, trying vainly to make out the cause of the

vague noises.

"It's natives--at a distance, Jack, my lad," said Mackay. "They're

outside the tunnel; so we'll be all right if there's no' too many o'

them. I'm just hoping we've seen the full strength o' the tribe

already."

They resumed their march; and now they had less difficulty in making

progress owing to the continued increase of light, and as they proceeded

the confused babel of voices became more and more distinct. The tunnel

was by this time veering back towards its original course. Then suddenly

a bright light flashed upon them as through a giant lens. The exit of

the tunnel was in sight at last! Once more Mackay stopped, and was on

the point of making some cautionary remark; but even while he turned the

bright circle ahead was darkened, and several natives entered. A word at

that moment might have proved disastrous, and Bob gripped Mackay's arm

just in time; scarcely twenty yards separated them from their enemies.

The big man hesitated only for a moment, then quickly concealed his

rifle under his long cloak and walked slowly forward, his companions

copying his example without a murmur.

The oncoming warriors were now close beside them; but in the semi-light

of the cavern their dusky faces could not be distinguished. By this time

they had apparently become aware of the presence of the dauntless four,

for they stepped aside to let them pass, and addressed Mackay in a

series of unintelligible ejaculations--presumably of inquiry--to which

that gentleman answered by a non-committal grunt, and strode on his way.

And for the third time within an hour the natives brushed by the little

group, and left them unmolested; but on this occasion it was the

efficacy of their disguise which saved them--a fact which made the

Shadow effervesce with delight. However, it was yet too early to

rejoice, and Bob and Jack restrained their spirits with an effort. As

for Mackay, he made no sign that anything unusual had happened, and

walked on calmly as before, but a repressed cry of wonder burst from his

lips when he reached the end of the tunnel and gazed beyond on the land

which they had so eagerly sought, and his companions echoed his cry when

they, too, looked on the scene which lay before them. And little wonder,

for their eyes were drinking in a vision of rare beauty--it was as if a

glimpse of a tropical paradise had been vouchsafed them. In the near

distance the waters of a crystal lake glistened in the sunshine, and

lapped a coral-white beach, while, fringing its outer edge, and

extending back and upwards, a luxurious forest in miniature lay spread.

The sight was wonderfully cool and exhilarating to the beholders so long

accustomed to the arid desert. Here certainly was no lack of water, no

absence of shade.

But in their first hasty glance at the entrancing picture none of the

watchers had noticed the many bower-like structures which lined the edge

of the abundant foliage; and now Jack drew attention to this feature of

the landscape with some concern.

"There must be quite a population in the valley," said he.

Mackay nodded gravely. "My calculations have been all out," he remarked

in a subdued voice. Then his rage rose again. "But I'll no' go back," he

added fiercely, "until I have avenged my old comrades. I couldna do it,

my lads. But you----"

"Will stay with you," interrupted Bob, quietly.

"I reckon something's goin' to happen pretty sudden," grumbled the

Shadow, craning his neck out of the tunnel, and looking all around

anxiously.

The voices which they had heard while in the far back recesses of the

passage reached their ears close beside them, and towards the right. In

their eagerness they had overlooked the near vicinity while absorbed in

contemplation of the tiny lake and forest beyond; but now the Shadow's

gaze rested upon a crouching circle of warriors less than forty yards

from him, and it seemed as if each gaudily-bedecked native was eyeing

the figures at the mouth of the underground passage with the keenest

interest.

"Look, boss," said the Shadow, "they seem to be quite tame. The critters

must have seen us all the time."

Mackay raved silently at his lack of perception, and drawing back into

the recess, examined his rifle, and felt for his cartridge-belt

underneath his furry garb.

"Why," said Bob, "we forget we appear to be savages too; they won't

think there is anything wrong."

But in this conjecture Bob was soon proved to be very much mistaken.

Immediately the Shadow withdrew his head, an animated discussion

appeared to take place among the blacks, and their voices were raised to

an alarming pitch. Bob, though still keeping in the shade, could see the

dusky ring clearly by pressing hard against the rocky wall on his left,

and he noted with dismay the growing disturbance which followed the

advent and withdrawal of his companion's befeathered cranium.

"It's no use, Bob," said Mackay, coming up beside him, "They know we are

not the genuine article apparently, an' we've got to fight now whether

we will or no."

Yet still no attempt was made on the part of the natives to come to

closer quarters with the intruders, although many had arisen, bows in

hand, as if impatient for the fray.

"There's a curious old chap sitting in the middle," said Jack, peering

out of his shelter; "I wonder if he has anything to do with their

hesitation? He seems to have a lot to say."

Bob looked again, and caught a glimpse of an odd wizened figure sitting

amid the gesticulating warriors, and evidently endeavouring to restrain

their ardour. He had not been observable before, but a gap made in the

circle by the sudden movement of the restless band had revealed him, as

Jack had quickly noticed.

"He must be their king," remarked Mackay; "but it's vera strange that he

should want to delay the circus."

The grizzled old native certainly appeared to have considerable

influence over the others; there could be no doubt that he was a leader

of some sort, and his policy was clearly not the policy of his

followers, at which the watchers by the tunnel marvelled exceedingly.

For several minutes he continued to address the multitude, glancing

occasionally towards the objects of their wrath and waving his hand as

if signalling for some one on the heights through which Mackay and his

companions had come. But at last he ceased his wordy exhortations, and

slowly arose to his feet, donning as he did so a gigantic head-dress

fashioned out of the skin of some peculiar animal, the grinning head of

which had been cunningly retained in its pristine shape, so that the

living creature seemed to glare out savagely over the thick locks of the

wearer; and as he stood thus arrayed a tumultuous roar issued from the

lips of the awaiting horde, and they turned in a mass and marched

straight for the opening to the underground passage.

"Old Nebuchadnezzar has put his war-paint on at last," muttered Mackay.

"Now, my lads, let us rush them while we can. If we can stop them even

for a minute we'll win the day in spite o' their numbers."

"Let her go, boss!" yelled the Shadow from behind, and Mackay, with a

hoarse bellow of anger, dashed forward to meet the foe, his impetuous

comrades bounding closely at his heels. All were filled with the mad

desire to slay until the last. The lust of battle had taken hold of them

completely; no thought of the probable grim finale was theirs.

Their wild advance caused the blacks to hesitate momentarily, and the

front rank crowded back. Bob noticed in a flash the advantage which had

thus been given, and he knew why Mackay had so suddenly left the shelter

of the cavern. While the natives hustled together not a bow could be

bent. Quickly he dropped on one knee beside his leader, Jack and the

Shadow falling into line as if by a preconceived arrangement. Had they

discharged their rifles at that crucial moment their enemy would have

been mowed down before the leaden hail. But ere a finger pressed the

trigger, the old chief, with a shrill cry, which was heard high above

the din, leapt in front of his myrmidons, and, with an almost regal

gesture, waved them back. That he himself escaped being riddled with

bullets was a lasting testimony to the iron nerves of the dauntless four

who, even at such a critical juncture, disdained to fire on one whose

face was turned away from them. But they recovered themselves promptly

and prepared to follow up their apparent triumph, yet the ancient

warrior stayed them with outstretched hand.

"I'll soon throw him out of the way," roared Mackay, dashing forward.

Before he reached the patriarchal chief, however, a stentorian call from

behind arrested his attention, and he stood rooted to the spot, dazed

and bewildered. Again the cry sounded in his ears--

"Come back, Jim; for God's sake, come back. There's three hundred

against you."

He staggered and would have fallen, had not Bob's strong arm supported

him; then he turned almost fearfully. Five tall figures were hastening

frantically down the hillside, and the foremost was the watcher of the

summit. As in a dream Mackay raised his rifle, and he did not seem to

notice when Bob pressed the deadly tube down. He was gazing with wild

staring eyes at the approaching form.

"Great Centipedes!" howled the Shadow, in amazement. "It's a white man!"

That broke the spell. With a hoarse exclamation, Mackay rushed to meet

the new-comer.

[Illustration: "MACKAY RUSHED TO MEET THE NEW-COMER"]

"Dick!" he cried.

"Yes, it's me, Jim," came the answer. "I knew you would come."
