"Yes, but no more will go; the last earthquake has made the route impa.s.sable."

"To mules," said the Major, "but not to men."

"Ah, that's your concern; I have done all I could. My mules and myself are at your service to try the other pa.s.ses of the Cordilleras."

"And that would delay us?"

"Three days at least."

Glenarvan listened silently. He saw the CATAPEZ was right. His mules could not go farther. When he talked of returning, however, Glenarvan appealed to his companions and said:

"Will you go on in spite of all the difficulty?"

"We will follow your Lordship," replied Tom Austin.

"And even precede you," added Paganel. "What is it after all? We have only to cross the top of the mountain chain, and once over, nothing can be easier of descent than the slopes we shall find there. When we get below, we shall find BAQUEANOS, Argentine shepherds, who will guide us through the Pampas, and swift horses accustomed to gallop over the plains. Let's go forward then, I say, and without a moment's hesitation."

"Forward!" they all exclaimed. "You will not go with us, then?" said Glenarvan to the CATAPEZ.

"I am the muleteer," was the reply.

"As you please," said Glenarvan.

"We can do without him," said Paganel. "On the other side we shall get back into the road to Antuco, and I'm quite sure I'll lead you to the foot of the mountain as straight as the best guide in the Cordilleras."

Accordingly, Glenarvan settled accounts with the CATAPEZ, and bade farewell to him and his PEONS and mules. The arms and instruments, and a small stock of provisions were divided among the seven travelers, and it was unanimously agreed that the ascent should recommence at once, and, if necessary, should continue part of the night. There was a very steep winding path on the left, which the mules never would have attempted.

It was toilsome work, but after two hours' exertion, and a great deal of roundabout climbing, the little party found themselves once more in the pa.s.s of Antuco.

They were not far now from the highest peak of the Cordilleras, but there was not the slightest trace of any beaten path. The entire region had been overturned by recent shocks of earthquake, and all they could do was to keep on climbing higher and higher. Paganel was rather disconcerted at finding no way out to the other side of the chain, and laid his account with having to undergo great fatigue before the topmost peaks of the Andes could be reached, for their mean height is between eleven and twelve thousand six hundred feet. Fortunately the weather was calm and the sky clear, in addition to the season being favorable, but in Winter, from May to October, such an ascent would have been impracticable. The intense cold quickly kills travelers, and those who even manage to hold out against it fall victims to the violence of the TEMPORALES, a sort of hurricane peculiar to those regions, which yearly fills the abysses of the Cordilleras with dead bodies.

They went on toiling steadily upward all night, hoisting themselves up to almost inaccessible plateaux, and leaping over broad, deep creva.s.ses.

They had no ropes, but arms linked in arms supplied the lack, and shoulders served for ladders. The strength of Mulrady and the dexterity of Wilson were taxed heavily now. These two brave Scots multiplied themselves, so to speak. Many a time, but for their devotion and courage the small band could not have gone on. Glenarvan never lost sight of young Robert, for his age and vivacity made him imprudent. Paganel was a true Frenchman in his impetuous ardor, and hurried furiously along. The Major, on the contrary, only went as quick as was necessary, neither more nor less, climbing without the least apparent exertion. Perhaps he hardly knew, indeed, that he was climbing at all, or perhaps he fancied he was descending.

The whole aspect of the region had now completely changed. Huge blocks of glittering ice, of a bluish tint on some of the declivities, stood up on all sides, reflecting the early light of morn. The ascent became very perilous. They were obliged to reconnoiter carefully before making a single step, on account of the creva.s.ses. Wilson took the lead, and tried the ground with his feet. His companions followed exactly in his footprints, lowering their voices to a whisper, as the least sound would disturb the currents of air, and might cause the fall of the ma.s.ses of snow suspended in the air seven or eight hundred feet above their heads.

They had come now to the region of shrubs and bushes, which, higher still, gave place to gra.s.ses and cacti. At 11,000 feet all trace of vegetation had disappeared. They had only stopped once, to rest and s.n.a.t.c.h a hurried meal to recruit their strength. With superhuman courage, the ascent was then resumed amid increasing dangers and difficulties. They were forced to bestride sharp peaks and leap over chasms so deep that they did not dare to look down them. In many places wooden crosses marked the scene of some great catastrophes.

About two o'clock they came to an immense barren plain, without a sign of vegetation. The air was dry and the sky unclouded blue. At this elevation rain is unknown, and vapors only condense into snow or hail.

Here and there peaks of porphyry or basalt pierced through the white winding-sheet like the bones of a skeleton; and at intervals fragments of quartz or gneiss, loosened by the action of the air, fell down with a faint, dull sound, which in a denser atmosphere would have been almost imperceptible.

However, in spite of their courage, the strength of the little band was giving way. Glenarvan regretted they had gone so 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 pa.s.sed 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 f.a.ggot 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.
