For the first half-hour we made fairly good headway through the straggling belt of eucalypti covering the lower slopes, then we emerged on a treeless, boulder-strewn expanse, on which the sun scintillated with burning intensity. Over this scorched area we clambered as best we could. The sharp rubble cut through our boots, and the glistening rocks, hot as a fiery furnace, burnt our clutching hands. Our mountain exploration was surely becoming less of a picnic than we had antic.i.p.ated. Directly above, a solid ma.s.s of basalt reared its head, gaunt and bare, but when we came to the edge of the gla.s.s-like cap, we hesitated--we might as well have attempted to cross a field of molten metal. From this point various dry channels tore down the face of the hill, radiating outwards into the plain. They were so silted up with rock fragments and ironsand as to be scarcely perceptible, but Phil"s trained eye at once noted their significance.
"Ages ago," said he, "those gullies were filled with rushing torrents, which goes to prove that a crater lake existed on the top of the mountain."
He walked over to one of the ancient beds and sc.r.a.ped among the drift of black sand conglomeration. At once several water-worn specimens of quartzite were uncovered, and of these over fifty per cent bore the characteristic markings of the ruby.
"Fill your pockets with these, Mac," he said quietly. "They should be worth considerably more than their weight in gold."
Prolonged travelling in Western Australia does not tend to develop enthusiasm, and the extraordinary find so unexpectedly made was greeted by no extravagant manifestations of delight. Relief rather than joy was ours at that moment, for in one important sense at least our quest seemed surely ended.
"If we can find water in the vicinity we"ll camp at the foot of the hill for a few days, boys," I announced with much satisfaction. "Meanwhile we had better explore a little further, and see what the country looks like from the summit."
[Ill.u.s.tration: A NATIVE CAMP.]
But Mac and Stewart were already busily engaged collecting specimens, which they stowed in every nook and corner of their ragged garments.
"Come along, you gloating misers!" cried Phil, as he and I started to negotiate the last stiff climb.
"There"s nae time like the present," growled Mac oracularly, pursuing his congenial task with supreme content.
"I"m o" the same opeenion," spluttered Stewart, who had turned his mouth into a receptacle for the finest gems in his collection. So we crawled over the smooth climaxing dome alone. Our surprise was great when on reaching the top we found ourselves on the edge of a small circular area that depressed ever so slightly towards the centre, providing a s.p.a.ce which looked remarkably like an ordinary circus ring. This impression was much heightened by the fact that a well-marked path seemed to have been worn around the periphery; but through what agency this had been done I could not well imagine. We stood surveying the odd arena, filled with wonder.
"It is one of Nature"s strange tricks," I said, after a considerable silence.
Phil looked doubtful, but he did not speak. Then we made a further discovery. The saucer-shaped hollow was graven out of a solid lava formation, but exactly over the point of its deepest dip several crumbling branches lay strewn. Of a certainty they had not come there of their own accord, and at once we were overwhelmed with dire misgivings.
"It means that there are some native tribes in the neighbourhood," said Phil, watching me kick aside the branches with much interest. What we saw then did not add to our bewilderment, for we had already partly guessed the significance of the peculiar arrangement. Under the layer of brush, a narrow, funnel-like shaft had been hid, which apparently descended into the heart of the mouldering desert sentinel, but why this hole had been covered was more than we could understand. While we stood in silent contemplation of the remarkable state of affairs disclosed, our energetic companions, having marvelled at our long absence, swarmed up beside us, breathing heavily.
"Nebuchadnezzar"s furnace wouldna be in the same street wi" that biler,"
began Mac, patting his scantily-covered knees with tender solicitude.
"I smell n.i.g.g.e.r," howled Stewart, taking in the scene at a glance.
"That"s aye what happens when A come oot withoot my gun," sorrowfully muttered the first arrival, moving over to the narrow crater mouth and peering into the darkness with studied nonchalance.
It so happened, however, that the loose pockets of his flimsy upper garment were filled to overflowing with cherished specimens, and the half-kneeling att.i.tude which he a.s.sumed allowed them to escape in a copious stream, so that they fell down into the depths. With a bellow of rage he drew back, but not before the bulk of his treasure had disappeared; then the air was filled with the fulness of his wrath, and sulphurous expressions loud and deep were hurled into the Stygian gloom.
"Calm yersel", Mac--calm yersel"," adjured Stewart soothingly.
"Calm be d----d!" roared the afflicted one. "Hoo am I goin" to get back my rubies?"
This was a point which seemed unanswerable.
"You"ll get more to-morrow, Mac," I said, "but we"ll have to return to the camels now, in case the natives get a hold of them before we have time to take precautions."
He remained unappeased, however.
"We"ll mebbe hae to flee for oor lives afore morning," he protested gloomily. "It"s no the first time we"ve had to strike camp in a hurry."
As he spoke he unwound from his waist a long coil of rope which he usually carried in case of emergency, and, with dogged determination, proceeded to sound the depths of the well.
"You"d better let me gang," advised Stewart, guessing his companion"s intentions before they had been uttered; "I"m no sae bulky as you, an"----"
He got no further.
"Mak" nae mair allooshuns," came the answer, with a chilling dignity.
"I"ll engineer this funeral mysel"."
Hastily fastening a fragment of rock to the end of the rope, he dropped it into the narrow orifice and carefully noted the length of line run out. All this time Phil and I had made little comment, never expecting that any satisfactory bottom would be found; but great was our surprise to see the rope become stationary when little over twenty feet had been paid out.
"I"m really anxious to know what is at the bottom of that hole, Mac,"
said Phil; "but I hope you don"t find a nice fat, healthy crocodile awaiting you----"
"Haud the end o" the rope, Phil, an" dinna speechify," broke out the hara.s.sed Mac impatiently; and he wriggled his somewhat substantial form into the vertical channel until his arms alone saved him from falling down altogether.
"It"s a--a tight fit," he grumbled, with diminishing enthusiasm. "Noo haud on tight, ye deevils; haud on--haud on!"
His voice rumbled up dolorously to our ears as we lowered him gently into the mysterious pit, until, when the lower depths were reached, the rocky vault seemed to tremble with vague echoes. Suddenly the strain on the rope was relaxed, and we waited expectantly for tidings from the adventurer.
"It"s vera dark doon here," came the ghost-like voice from the underground. "I think--I think I"ll come up----"
"What sort of bottom have you got, Mac?" I shouted. "Try and fetch up a specimen."
A few more inconsequent remarks issued from the pit mouth, then we could see the dull glimmer of a match far below. Almost immediately after a jubilant yell of triumph swelled up to the surface.
"I"ve got them! I"ve got them!" he cried. "An" there"s gold quartz here, foreby." Then came a crash, a rumble, and a dull, heavy splash, and we on the surface gazed on each other in dismay.
"Let me doon! Let me doon!" wailed Stewart. "Something serious has happened to Mac. Haud on to the rope." He let himself into the narrow aperture with unwonted agility, and, with an unspeakable fear in our hearts, Phil and I commenced to pay out the rope.
"Wha the--who the----Wha"s blockin" the licht?" bellowed a well-known voice from the bowels of the earth, which had the effect of ejecting Stewart into the outer air with a celerity astonishing to behold. Then we breathed again.
Apparently some ledge had first intercepted our sounding-line, and also provided a precarious foothold for our valiant a.s.sociate; but that the true bottom had now been reached there was little room for doubt.
"I might have guessed before," said Phil, "that the crater would have an impervious base, and so retain any rain that might be collected."
Judging by the snorts and puffs emitted by the individual who was in a position to know, the shaft must have held a fair amount of liquid contents.
"Haul on the rope, for heaven"s sake!" spluttered he. "This water would pushion a n.i.g.g.e.r. Haul me up quick! There"s snakes an" wee crocodiles tickling me!"
In haste we endeavoured to obey his beseeching call, but the sodden cord was not equal to the strain, and twice the strands snapped before our comrade"s bulk was raised from the water.
"We"d better double the line, boys," I said. "Mac must have increased in weight during his sojourn below."
The unfortunate victim of his own prowess groaned lugubriously from his dank and dark prison, but found time between his grumbling to curse right heartily the various denizens of his watery environment.
"Be patient, Mac, be patient," counselled Stewart, rearranging the haulage system. "Scientific exploration is not without its drawbacks, as you should well ken by this time." He continued addressing choice words of wisdom to his helpless compatriot while he deftly spliced the rope.
During this lull in operations I chanced to look abroad over the sweltering plain, and at once my eyes detected the curling "smokes" of a native camp. We had been too busily engrossed with other matters since our arrival on the hill-top to observe the landscape on the east, and now the nearness of a possible hostile band appalled me. Our rifles had been left in camp, and I only carried a revolver.
"By Jove!" said Phil, "we are going to be in a fix." Then a shout of alarm broke from him: "There"s about a dozen of the ugliest bucks I ever saw coming right up the hill," he said feebly. I followed his gaze, and, sure enough, I could see a number of hideously-scarred and feather-bedecked warriors making their way through the scraggy brushwood, scarcely a hundred yards from where we stood. With frantic haste, we again endeavoured to rescue our companion from his awkward predicament, but fate was surely against us. We had with our combined efforts raised him only a few feet when the rope came in contact with the broken ledge, and the strands parted like so many straws, so that Mac was once more precipitated back into the slimy waters. Our plans had now to be made quickly.
