"Ah, McNabbs, I see you have small faith in my Spanish yet."

"Well, try it, my good friend."

"So I will."

And turning round to the Patagonian he began his narrative, breaking down frequently for the want of a word, and the difficulty of making certain details intelligible to a half-civilized Indian. It was quite a sight to see the learned geographer. He gesticulated and articulated, and so worked himself up over it, that the big drops of sweat fell in a cascade down his forehead on to his chest. When his tongue failed, his arms were called to aid. Paganel got down on the ground and traced a geographical map on the sand, showing where the lines of lat.i.tude and longitude cross and where the two oceans were, along which the Carmen route led. Thalcave looked on composedly, without giving any indication of comprehending or not comprehending.

The lesson had lasted half an hour, when the geographer left off, wiped his streaming face, and waited for the Patagonian to speak.

"Does he understand?" said Glenarvan.

"That remains to be seen; but if he doesn't, I give it up," replied Paganel.

Thalcave neither stirred nor spoke. His eyes remained fixed on the lines drawn on the sand, now becoming fast effaced by the wind.

"Well?" said Paganel to him at length.

The Patagonian seemed not to hear. Paganel fancied he could detect an ironical smile already on the lips of the Major, and determined to carry the day, was about to recommence his geographical ill.u.s.trations, when the Indian stopped him by a gesture, and said:

"You are in search of a prisoner?"

"Yes," replied Paganel.

"And just on this line between the setting and rising sun?" added Thalcave, speaking in Indian fashion of the route from west to east.

"Yes, yes, that's it."

"And it's your G.o.d," continued the guide, "that has sent you the secret of this prisoner on the waves."

"G.o.d himself."

"His will be accomplished then," replied the native almost solemnly. "We will march east, and if it needs be, to the sun."

Paganel, triumphing in his pupil, immediately translated his replies to his companions, and exclaimed:

"What an intelligent race! All my explanations would have been lost on nineteen in every twenty of the peasants in my own country."

Glenarvan requested him to ask the Patagonian if he had heard of any foreigners who had fallen into the hands of the Indians of the Pampas.

Paganel did so, and waited an answer.

"Perhaps I have."

The reply was no sooner translated than the Patagonian found himself surrounded by the seven men questioning him with eager glances. Paganel was so excited, he could hardly find words, and he gazed at the grave Indian as if he could read the reply on his lips.

Each word spoken by Thalcave was instantly translated, so that the whole party seemed to hear him speak in their mother tongue.

"And what about the prisoner?" asked Paganel.

"He was a foreigner."

"You have seen him?"

"No; but I have heard the Indian speak of him. He is brave; he has the heart of a bull."

"The heart of a bull!" said Paganel. "Ah, this magnificent Patagonian language. You understand him, my friends, he means a courageous man."

"My father!" exclaimed Robert Grant, and, turning to Paganel, he asked what the Spanish was for, "Is it my father."

"_Es mio padre_," replied the geographer.

Immediately taking Thalcave's hands in his own, the boy said, in a soft tone:

"_Es mio padre_."

"_Suo padre_," replied the Patagonian, his face lighting up.

He took the child in his arms, lifted him up on his horse, and gazed at him with peculiar sympathy. His intelligent face was full of quiet feeling.

But Paganel had not completed his interrogations. "This prisoner, who was he? What was he doing? When had Thalcave heard of him?" All these questions poured upon him at once.

He had not long to wait for an answer, and learned that the European was a slave in one of the tribes that roamed the country between the Colorado and the Rio Negro.

"But where was the last place he was in?"

"With the Cacique Calfoucoura."

"In the line we have been following?"

"Yes."

"And who is this Cacique?"

"The chief of the Poyuches Indians, a man with two tongues and two hearts."

"That's to say false in speech and false in action," said Paganel, after he had translated this beautiful figure of the Patagonian language.

"And can we deliver our friend?" he added.

"You may if he is still in the hands of the Indians."

"And when did you last hear of him?"

"A long while ago; the sun has brought two summers since then to the Pampas."

The joy of Glenarvan can not be described. This reply agreed perfectly with the date of the doc.u.ment. But one question still remained for him to put to Thalcave.

"You spoke of a prisoner," he said; "but were there not three?"
