far into the interior of the mountain when he saw how exhausted his men had become. Young Robert held out manfully, but he could not go much farther.
At three o'clock Glenarvan stopped and said:
"We must rest."
He knew if he did not himself propose it, no one else would.
"Rest?" rejoined Paganel; "we have no place of shelter."
"It is absolutely necessary, however, if it were only for Robert."
"No, no," said the courageous lad; "I can still walk; don't stop."
"You shall be carried, my boy; but we must get to the other side of the Cordilleras, cost what it may. There we may perhaps find some hut to cover us. All I ask is a two hours' longer march."
"Are you all of the same opinion?" said Glenarvan.
"Yes," was the unanimous reply: and Mulrady added, "I'll carry the boy."
The march eastward was forthwith resumed. They had a frightful height to climb yet to gain the topmost peaks. The rarefaction of the atmosphere produced that painful oppression known by the name of PUNA. Drops of blood stood on the gums and lips, and respiration became hurried and difficult. However strong the will of these brave men might be, the time came at last when their physical powers failed, and vertigo, that terrible malady in the mountains, destroyed not only their bodily strength but their moral energy. Falls became frequent, and those who fell could not rise again, but dragged themselves along on their knees.
But just as exhaustion was about to make short work of any further ascent, and Glenarvan's heart began to sink as he thought of the snow lying far as the eye could reach, and of the intense cold, and saw the shadow of night fast overspreading the desolate peaks, and knew they had not a roof to shelter them, suddenly the Major stopped and said, in a calm voice, "A hut!"
Chapter XIII.
A Sudden Descent
ANYONE else but McNabbs might have passed the hut a hundred times, and gone all round it, and even over it without suspecting its existence. It was covered with snow, and scarcely distinguishable from the surrounding rocks; but Wilson and Mulrady succeeded in digging it out and clearing the opening after half an hour's hard work, to the great joy of the whole party, who eagerly took possession of it.
They found it was a CASUCHA, constructed by the Indians, made of ADOBES, a species of bricks baked in the sun. Its form was that of a cube, 12 feet on each side, and it stood on a block of basalt. A stone stair led up to the door, the only opening; and narrow as this door was, the hurricane, and snow, and hail found their way in when the TEMPORALES were unchained in the mountains.
Ten people could easily find room in it, and though the walls might be none too water-tight in the rainy season, at this time of the year, at any rate, it was sufficient protection against the intense cold, which, according to the thermometer, was ten degrees below zero. Besides, there was a sort of fireplace in it, with a chimney of bricks, badly enough put together, certainly, but still it allowed of a fire being lighted.
"This will shelter us, at any rate," said Glenarvan, "even if it is not very comfortable. Providence has led us to it, and we can only be thankful."
"Why, it is a perfect palace, I call it," said Paganel; "we only want flunkeys and courtiers. We shall do capital here."
"Especially when there is a good fire blazing on the hearth, for we are quite as cold as we are hungry. For my part, I would rather see a good faggot just now than a slice of venison."
"Well, Tom, we'll try and get some combustible or other," said Paganel.
"Combustibles on the top of the Cordilleras!" exclaimed Mulrady, in a dubious tone.
"Since there is a chimney in the CASUCHA," said the Major, "the probability is that we shall find something to burn in it."
"Our friend McNabbs is right," said Glenarvan. "Get everything in readiness for supper, and I'll go out and turn woodcutter."
"Wilson and I will go with you," said Paganel.
"Do you want me?" asked Robert, getting up.
"No, my brave boy, rest yourself. You'll be a man, when others are only children at your age," replied Glenarvan.
On reaching the little mound of porphyry, Glenarvan and his two companions left the CASUCHA. In spite of the perfect calmness of the atmosphere, the cold was stinging. Paganel consulted his barometer, and found that the depression of the mercury corresponded to an elevation of 11,000 feet, only 910 meters lower than Mont Blanc. But if these mountains had presented the difficulties of the giant of the Swiss Alps, not one of the travelers could have crossed the great chain of the New World.
On reaching a little mound of porphyry, Glenarvan and Paganel stopped to gaze about them and scan the horizon on all sides. They were now on the summit of the Nevadas of the Cordilleras, and could see over an area of forty miles. The valley of the Colorado was already sunk in shadow, and night was fast drawing her mantle over the eastern slopes of the Andes. The western side was illumined by the rays of the setting sun, and peaks and glaciers flashed back his golden beams with dazzling radiance. On the south the view was magnificent. Across the wild valley of the Torbido, about two miles distant, rose the volcano of Antuco. The mountain roared like some enormous monster, and vomited red smoke, mingled with torrents of sooty flame. The surrounding peaks appeared on fire. Showers of red-hot stones, clouds of reddish vapor and rockets of lava, all combined, presented the appearance of glowing sparkling streams. The splendor of the spectacle increased every instant as night deepened, and the whole sky became lighted up with a dazzling reflection of the blazing crater, while the sun, gradually becoming shorn of his sunset glories, disappeared like a star lost in the distant darkness of the horizon.
Paganel and Glenarvan would have remained long enough gazing at the sublime struggle between the fires of earth and heaven, if the more practical Wilson had not reminded them of the business on hand. There was no wood to be found, however, but fortunately the rocks were covered with a poor, dry species of lichen. Of this they made an ample provision, as well as of a plant called LLARETTA, the root of which burns tolerably well. This precious combustible was carried back to the CASUCHA and heaped up on the hearth. It was a difficult matter to kindle it, though, and still more to keep it alight. The air was so rarefied that there was scarcely oxygen enough in it to support combustion. At least, this was the reason assigned by the Major.
"By way of compensation, however," he added, "water will boil at less than 100 degrees heat. It will come to the point of ebullition before 99 degrees."
McNabbs was right, as the thermometer proved, for it was plunged into the kettle when the water boiled, and the mercury only rose to 99 degrees. Coffee was soon ready, and eagerly gulped down by everybody. The dry meat certainly seemed poor fare, and Paganel couldn't help saying:
"I tell you what, some grilled llama wouldn't be bad with this, would it? They say that the llama is substitute for the ox and the sheep, and I should like to know if it is, in an alimentary respect."
"What!" replied the Major. "You're not content with your supper, most learned Paganel."
"Enchanted with it, my brave Major; still I must confess I should not say no to a dish of llama."
"You are a Sybarite."
"I plead guilty to the charge. But come, now, though you call me that, you wouldn't sulk at a beefsteak yourself, would you?"
"Probably not."
"And if you were asked to lie in wait for a llama, notwithstanding the cold and the darkness, you would do it without the least hesitation?"
"Of course; and if it will give you the slightest pleasure—"
His companions had hardly time to thank him for his obliging good nature, when distant and prolonged howls broke on their ear, plainly not proceeding from one or two solitary animals, but from a whole troop, and one, moreover, that was rapidly approaching.
Providence had sent them a supper, as well as led them to a hut. This was the geographer's
