The Plant Hunters Part 11

He did not need to point out the spot. The eyes of Caspar and Ossaroo were already turned upon it.--Away down the ravine as far as they could see the surface of the glacier appeared in motion, like sea-billows; huge blocks of ice were thrown to the top and rolled over, with a rumbling cras.h.i.+ng noise, while large blue fragments raised high above the general surface, were grinding and crumbling to pieces against the faces of the cliffs. A cloud of snow-spray, rising like a thick white mist, filled the whole ravine--as if to conceal the work of ruin that was going on--and underneath this ghostly veil, the crus.h.i.+ng and tearing for some moments continued. Then all at once the fearful noises ceased, and only the screaming of the birds, and the howling of beasts, disturbed the silence of the place.

Pale, shuddering, almost paralysed by fear, the hunters had thrown themselves on their hands and knees, expecting every moment to feel the glacier move beneath them,--expecting to sink beneath the surface, or be crushed amidst the billows of that icy sea. So long as the dread sounds echoed in their ears, their hearts were filled with consternation, and long after the cras.h.i.+ng and crackling ceased, they remained the victims of a terrible suspense; but they felt that that portion of the glacier upon which they were did not move. It still remained firm; would it continue so?

They knew not the moment it, too, might commence sliding downward, and bury them under its ma.s.ses, or crush them in some deep creva.s.se.

O heavens! the thought was fearful. It had paralysed them for a moment; and for some time after the noises had ceased, they remained silent and motionless. Indeed, absurd as it may seem, each dreaded to stir, lest the very motion of his body might disturb the icy ma.s.s upon which he was kneeling!

Reflection soon came to their aid. It would never do to remain there.

They were still exposed to the danger. Whither could they retreat? Up the ravine might be safer? Above them the ice had not yet stirred. The ruin had all been below--below the creva.s.se they had just crossed.

Perhaps the rocks would afford a footing? They would not move, at all events, even if the upper part of the glacier should give way; but was there footing to be found upon them?

They swept their eyes along the nearest cliff. It offered but little hope. Yes--upon closer inspection there was a ledge--a very narrow one, but yet capable of giving refuge to two or three men; and, above all, it was easy of access. It would serve their purpose.

Like men seeking shelter from a heavy shower, or running to get out of the way of some impending danger, all three made for the ledge; and after some moments spent in sprawling and climbing against the cliff, they found themselves standing safely upon it.--Small standing-room they had. Had there been a fourth, the place would not have accommodated him. There was just room enough for the three side by side, and standing erect.

Small as the s.p.a.ce was, it was a welcome haven of refuge. It was the solid granite, and not the fickle ice. It looked eternal as the hills; and, standing upon it, they breathed freely.

But the danger was not over, and their apprehensions were still keen.

Should the upper part of the glacier give way, what then? Although it could not reach them where they stood, the surface might sink far below its present level, and leave them on the cliff--upon that little ledge on the face of a black precipice!

Even if the upper ice held firm, there was another thought that now troubled them. Karl knew that what had occurred was a _glacier slide_-- a phenomenon that few mortals have witnessed. He suspected that the slide had taken place in that portion of the glacier below the creva.s.se they had just crossed. If so, the lye would be widened, the huge gneiss rock that bridged it gone, and their _retreat down the glacier cut off_!

Upward they beheld nothing but the beetling cliffs meeting together. No human foot could scale them. If no outlet offered in that direction, then, indeed, might the jesting allusion of Caspar be realised. They might be imprisoned between those walls of black granite, with nought but ice for their bed, and the sky for their ceiling. It was a fearful supposition, but all three did not fail to entertain it.

As yet they could not tell whether their retreat downwards was in reality cut off. Where they stood an abutment of the cliff hid the ravine below. They had rushed to their present position, with the first instinct of preservation. In their flight, they had not thought of looking either toward the creva.s.se or the gneiss rock.--Other large boulders intervened, and they had not observed whether it was gone.

They trembled to think of such a thing.

The hours pa.s.sed; and still they dared not descend to the glacier.

Night came on, and they still stood upon their narrow perch. They hungered, but it would have been of no use to go down to the cold icy surface. That would not have satisfied their appet.i.te.

All night long they remained standing upon the narrow ledge; now on one foot, now on the other, now resting their backs against the granite wall, but all night, without closing an eye in sleep. The dread of the capricious ice kept them on their painful perch.

They could bear it no longer. With the first light of morning they determined upon descending.

The ice had remained firm during the night. No farther noises had been heard. They gradually recovered confidence; and as soon as the day began to break, all three left the ledge, and betook themselves once more to the glacier.

At first they kept close to the cliff; but, after a while, ventured out far enough to get a view of the ravine below.

Caspar mounted upon a rocky boulder that lay upon the surface of the glacier. From the top of this he could see over the others. _The creva.s.se was many yards wide. The bridge-rock was gone_!

CHAPTER TWENTY THREE.

THE Pa.s.s.

The philosophy of the movement of glaciers is but ill understood, even by the most accomplished geologists. It is supposed that the under surface of these great icy ma.s.ses is detached from the ground by the thaw which continually takes place there, caused by the radiating heat of the earth. Water is also an agent in loosening their hold; for it is well-known that currents of water--sometimes large streams,--run under the glaciers. The icy ma.s.s thus detached, and resting on an inclined surface, is carried down by its own weight.

Sometimes only a very small portion of a glacier moves, causing a fissure above the part that has given way; and at other times these fissures are closed up, by the sliding of that portion next above them.

An unusually hot summer produces these effects upon the glacier ice, combined with the falling of avalanches, or mountain slides, which, with their weight, serve to impel the icy ma.s.s downwards.

The weight of our three hunters was but as a feather, and could have had no effect in giving motion to the glacier; but it is possible that the gneiss rock was just upon the balance when they crossed it. Thawed around its surface, it had no cohesion with the ice on which it rested; and, as a feather turns the scale, their crossing upon it may have produced a motion, which resulted in its fall.

So vast a ma.s.s hurled into the great cleft, and acting as a driven wedge, may have been the feather's touch that imparted motion to a section of the glacier, already hanging upon the balance, and ready to slide downwards.

Whether or not they had any agency in producing this fearful phenomenon, our travellers reflected not at the time. They were far too much terrified at the result to speculate upon causes. One after another they mounted upon the great boulder, and satisfied themselves of the facts that the creva.s.se had widened,--the bridge-rock had disappeared,-- and their retreat was cut off!

After a little, they ventured closer to the fearful chasm. They climbed upon a ledge of the precipice, that gave them a better view of it.

From this elevation they could partially see into the cleft. At the surface it was many yards wide. It appeared to be hundreds of feet in depth. Human agency could not have bridged it. All hope of getting back down the glacier was at an end; and with consternation in their looks, they turned their faces away, and commenced ascending towards the head of the ravine.

They advanced with timid steps. They spoke not at all, or only in low murmuring voices. They looked right and left, eagerly scanning the precipice on both sides. On each side of them towered the black cliffs, like prison walls, frowning and forbidding. No ledge of any size appeared on either; no terrace, no sloping ravine, that might afford them a path out of that dark valley. The cliffs, sheer and smooth, presented no hold for the human foot. The eagles, and other birds that screamed over their heads, alone could scale them.

Still they had not lost hope. The mind does not yield to despair without full conviction. As yet they were not certain that there was no outlet to the ravine; and until certain they would not despair.

They observed the tracks of the musk-deer as they went on. But these were no longer fresh; it was the trail of yesterday.

They followed this trail with renewed hopes,--with feelings of joy. But it was not the joy of the hunter who expects ere long to overtake his game. No, directly the reverse. Hungry as all three were, they _feared_ to overtake the game; they dreaded the discovery of fresh tracks!

You will wonder at this; but it is easily explained. They had reasoned with themselves, that if there existed any outlet above, the deer would have gone out by it. If the contrary, the animal would still be found near the head of the ravine. Nothing would have been less welcome than the sight of the deer at that moment.

Their hopes rose as they advanced. No fresh tracks appeared upon the glacier. The trail of the musk-deer still continued onward and upward.

The creature had not halted, nor even strayed to either side. It had gone straight on, as though making for some retreat already known to it.

Here and there it had made detours; but these had been caused by lyes in the ice, or boulders, that lay across the path.

With beating hearts the trackers kept on; now scanning the cliffs on each hand, now bending their eyes in advance.

At length they saw themselves within a hundred paces of the extreme end of the ravine, and yet no opening appeared. The precipice rose high and sheer as ever, on the right, on the left, before their faces. Nor break nor path cheered their eyes.

Where could the deer have gone? The ground above was pretty clear of _debris_. There were some loose rocks lying on one side. Had it hidden behind these? If so, they would soon find it; for they were within a few paces of the rocks.

They approached with caution. They had prepared their weapons for a shot. Despite their fears, they had still taken some precautions.

Hunger instigated them to this.

Caspar was sent on to examine the covert of rocks, while Karl and the s.h.i.+karree remained in the rear to intercept the deer if it attempted to retreat down the ravine.

Caspar approached with due caution. He crawled silently up to the boulders. He placed himself close to the largest; and, raising his head, peeped over it.

There was no deer behind the rock, nor any traces of it in the snow.

He pa.s.sed on to the next, and then to the next. This brought him into a new position, and near the head of the ravine; so that he could now see the whole surface of the glacier.

There was no musk-deer to be seen; but a spectacle greeted his eyes far more welcome than the sight of the largest herd of deer could have been to the keenest hunter; and a cry of joy escaped him on the instant.

He was seen to start out from the rocks, shouting as he ran across the ravine--

"Come on, brother! we are safe yet! There's a pa.s.s! there's a pa.s.s!"
