They were in a narrow valley, one of those gorges called by the Indians "quebrads," and on reaching the end, a wall of porphyry rose perpendicularly before them, and barred further passage. The CATAPEZ, after vain attempts at finding an opening, dismounted, crossed his arms, and waited. Glenarvan went up to him and asked if he had lost his way.
"No, your Lordship," was the reply.
"But you are not in the pass of Antuco."
"We are."
"You are sure you are not mistaken?"
"I am not mistaken. See! there are the remains of a fire left by the Indians, and there are the marks of the mares and the sheep."
"They must have gone on then."
"Yes, but no more will go; the last earthquake has made the route impassable."
"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 passes 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 pass 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 crevasses. 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.
