“Let us see the map?” said the Major.

“Here it is, my dear McNabbs. We shall go through the capital of Araucania, and cut the Cordilleras by the pass of Antuco, leaving the volcano on the south, and gliding gently down the mountain sides, past the Neuquem and the Rio Colorado on to the Pampas, till we reach the Sierra Tapalquen, from whence we shall see the frontier of the province of Buenos Ayres. These we shall pass by, and cross over the Sierra Tandil, pursuing our search to the very shores of the Atlantic, as far as Point Medano.”

Paganel went through this programme of the expedition without so much as a glance at the map. He was so posted up in the travels of Frezier, Molina, Humboldt, Miers, and Orbigny, that he had the geographical nomenclature at his fingers’ ends, and could trust implicitly to his never-failing memory.

“You see then, friend,” he added, “that it is a straight course. In thirty days we shall have gone over it, and gained the eastern side before the DUNCAN, however little she may be delayed by the westerly winds.”

“Then the DUNCAN is to cruise between Corrientes and Cape Saint Antonie,” said John Mangles.

“Just so.”

“And how is the expedition to be organized?” asked Glenarvan.

“As simply as possible. All there is to be done is to reconnoiter the situation of Captain Grant and not to come to gunshot with the Indians. I think that Lord Glenarvan, our natural leader; the Major, who would not yield his place to anybody; and your humble servant, Jacques Paganel.”

“And me,” interrupted Robert.

“Robert, Robert!” exclaimed Mary.
