Rivers of Ice, Robert Michael Ballantyne [fun to read .txt] 📗

High on the summit of the precipice, where its edge cut sharply against the blue sky, could be seen the black boulders and _debris_ of the lateral moraine of the glacier. The day was unusually warm, and the ice melted so rapidly that parts of this moraine were being sent down in frequent avalanches. The rustle of _debris_ was almost incessant, and, ever and anon, the rustle rose into a roar as great boulders bounded over the edge, and, after dashing portions of the ice-cliffs into atoms, went smoking down into the chaos below. It was just beyond this chaos that the party stood.

"Now, Antoine," said the Professor, "I want you to go to the foot of that precipice and fix a stake in the ice there."

"Well, Monsieur, it shall be done," returned the guide, divesting himself of his knapsack and shouldering his axe and a stake.

"Meanwhile," continued the Professor, "I will watch the falling _debris_ to warn you of danger in time, and the direction in which you must run to avoid it. My friend Lawrence, with the aid of Captain Wopper, will fix the theodolite on yonder rocky knoll to our left."

"Nothin' for you an' me to do," said Gillie to the artist; "p'r'aps we'd better go and draw--eh?"

Slingsby looked at the blue spider before him with an amused smile, and agreed that his suggestion was not a bad one, so they went off together.

While Antoine was proceeding to the foot of the ice-cliffs on his dangerous mission, the Professor observed that the first direction of a falling stone's bound was no sure index of its subsequent motion, as it was sent hither and thither by the obstructions with which it met. He therefore recalled the guide.

"It won't do, Antoine, the danger is too great."

"But, Monsieur, if it is necessary--"

"But it is not necessary that _you_ should risk your life in the pursuit of knowledge. Besides, I must have a stake fixed half-way up the face of that precipice."

"Ah, Monsieur," said Antoine, with an incredulous smile, "that is not possible!"

To this the Professor made no reply, but ordered his guide to make a detour and ascend to the upper edge of the ice-precipice for the purpose of dislodging the larger and more dangerous blocks of stone there, and, after that, to plant a stake on the summit.

This operation was not quickly performed. Antoine had to make a long detour to get on the glacier, and when he did reach the moraine on the top, he found that many of the most dangerous blocks lay beyond the reach of his axe. However, he sent the smaller _debris_ in copious showers down the precipice, and by cleverly rolling some comparatively small boulders down upon those larger ones which lay out of reach, he succeeded in dislodging many of them. This accomplished, he proceeded to fix the stake on the upper surface of the glacier.

While he was thus occupied, the Professor assisted Lawrence in fixing the theodolite, and then, leaving him, went to a neighbouring heap of _debris_ followed by the Captain, whom he stationed there.

"I want you," he said, "to keep a good look-out and warn me as to which way I must run to avoid falling rocks. Antoine has dislodged many of them, but some he cannot reach. These enemies must be watched."

So saying, the Professor placed a stake and an auger against his breast, buttoned his coat over them, and shouldered his axe.

"You don't mean to say that you're agoing to go under that cliff?" exclaimed the Captain, in great surprise, laying his hand on the Professor's arm and detaining him.

"My friend," returned the man of science, "do not detain me. Time is precious just now. You have placed yourself under my orders for the day, and, being a seaman, must understand the value of prompt obedience. Do as I bid you."

He turned and went off at a swinging pace towards the foot of the ice-cliff, while the Captain, in a state of anxiety, amounting almost to consternation, sat down on a boulder, took off his hat, wiped his heated brow, pronounced the Professor as mad as a March hare, and prepared to discharge his duties as "the look-out."

Although cool as a cucumber in all circumstances at sea, where he knew every danger and how to meet or avoid it, the worthy Captain now almost lost self-control and became intensely agitated and anxious, insomuch that he gave frequent and hurried false alarms, which he no less hurriedly attempted to correct, sometimes in nautical terms, much to the confusion of the Professor.

"Hallo! hi! look out--starboard--sta-a-arboard!" he shouted wildly, on beholding a rock about the size of a chest of drawers spring from the heights above and rush downward, with a smoke of ice-dust and _debris_ following, "quick! there! no! _port_! Port! I say it's--"

Before he could finish the sentence, the mass had fallen a long way to the right of the Professor, and lay quiet on the ice not far from where the Captain stood.

In spite of the interruptions thus caused, the lower stake was fixed in a few minutes. The Professor then swung his axe vigorously, and began to cut an oblique stair-case in the ice up the sheer face of the precipice.

In some respects the danger to the bold adventurer was now not so great because, being, as it were, flat against the ice-cliffs, falling rocks were more likely, by striking some projection, to bound beyond him. Still there was the danger of deflected shots, and when, by cutting a succession of notches in which to place one foot at a time, he had ascended to the height of an average three-storey house, the danger of losing his balance or slipping a foot became very great indeed. But the man of science persevered in doing what he conceived to be his duty with as much coolness as if he were the leader of a forlorn hope. Following the example of experienced ice-men on steep places, he took good care to make the notches or steps slope a little inwards, never lifted his foot from one step until the next was ready, and never swung his axe until his balance was perfectly secured. Having gained a height of about thirty feet, he pierced a hole with his auger, fastened a stake in it, and descended amid a heavy cannonade of boulders and a smart fire of smaller _debris_.

During the whole proceeding Lawrence directed his friend as to the placing of the stake, and watched with surprise as well as anxiety, while Captain Wopper kept on shouting unintelligible words of warning in a state of extreme agitation. The guide returned just in time to see this part of the work completed, and to remonstrate gravely with the Professor on his reckless conduct.

"`All's well that ends well,' Antoine, as a great poet says," replied the Professor, with one of his most genial smiles. "We must run some risk in the pursuit of scientific investigation. Now then, Lawrence, I hope you have got the three stakes in the same line--let me see."

Applying his eye to the theodolite, he found that the stakes were in an exactly perpendicular line, one above another. He then carefully marked the spot occupied by the instrument and thus completed his labours for that time.

We may add here in passing that next day he returned to the same place, and found that in twenty-four hours the bottom stake had moved downwards a little more than two inches, the middle stake had descended a little more than three, and the upper stake exactly six inches. Thus he was enabled to corroborate the fact which had been ascertained by other men of science before him, that glacier-motion is more rapid at the top than at the bottom, where the friction against its bed tends to hinder its advance, and that the rate of flow increases gradually from the bottom upwards.

While these points of interest were being established, our artist was not less earnestly engaged in prosecuting his own peculiar work, to the intense interest of Gillie, who, although he had seen and admired many a picture in the London shop-windows, had never before witnessed the actual process by which such things are created.

Wandering away on the glacier among some fantastically formed and towering blocks or obelisks of ice, Mr Slingsby expressed to Gillie his admiration of their picturesque shapes and delicate blue colour, in language which his small companion did not clearly understand, but which he highly approved of notwithstanding.

"I think this one is worth painting," cried Slingsby, pausing and throwing himself into an observant attitude before a natural arch, from the roof of which depended some large icicles; "it is extremely picturesque."

"I think," said Gillie, with earnest gravity, "that yonder's one as is more picturesker."

He had carefully watched the artist's various observant attitudes, and now threw himself into one of these as he pointed to a sloping obelisk, the size of an average church-steeple, which bore some resemblance to the leaning-tower of Pisa.

"You are right, boy; that is a better mass. Come, let us go paint it."

While walking towards it, Gillie asked how such wild masses came to be made.

"I am told by the Professor," said Slingsby, "that when the ice cracks across, and afterwards lengthwise, the square blocks thus formed get detached as they descend the valley, and assume these fantastic forms."

"Ah! jis so. They descends the walley, does they?"

"So it is said."

Gillie made no reply, though he said in his heart, "you won't git me to swaller _that_, by no manner of means." His unbelief was, however, rebuked by the leaning-tower of Pisa giving a terrible rend at that moment, and slowly bending forward. It was an alarming as well as grand sight, for they were pretty near to it. Some smaller blocks of ice that lay below prevented the tower from being broken in its fall. These were crushed to powder by it, and then, as if they formed a convenient carriage for it, the mighty mass slid slowly down the slope for a few feet. It was checked for a moment by another block, which, however, gave way before the great pressure, fell aside and let it pass. The slope was slight at the spot so that the obelisk moved slowly, and once or twice seemed on the point of stopping, but as if it had become endowed with life, it made a sudden thrust, squeezed two or three obstacles flat, turned others aside, and thus wound its way among its fellows with a low groaning sound like some sluggish monster of the antediluvian world. Reaching a steeper part of the glacier, on the ridge of which it hung for a moment, as if unwilling to exert itself, it seemed to awake to the reality of its position. Making a lively rush, that seemed tremendously inconsistent with its weight, it shot over the edge of a yawning crevasse, burst with a thunderclap on the opposite ice-cliff, and went roaring into the dark bowels of the glacier, whence the echoes of its tumbling masses, subdued by distance, came up like the mutterings of evil spirits.

Gillie viewed this wondrous spectacle with an awe-stricken heart, and then vented his feelings in a prolonged yell of ecstasy.

"Ain't it splendid, sir?" he cried, turning
