"The PAMPERO generally brings a tempest which lasts three days, and may be always foretold by the depression of the mercury," he said. "But when the barometer rises, on the contrary, which is the case now, all we need expect is a few violent blasts. So you can make your mind easy, my good friend; by sunrise the sky will be quite clear again."

"You talk like a book, Paganel," replied Glenarvan.

"And I am one; and what's more, you are welcome to turn over my leaves whenever you like."

The book was right. At one o'clock the wind suddenly lulled, and the weary men fell asleep and woke at daybreak, refreshed and invigorated.

It was the 20th of October, and the tenth day since they had left Talcahuano. They were still ninety miles from the point where the Rio Colorado crosses the thirty-seventh parallel, that is to say, about two days' journey. Glenarvan kept a sharp lookout for the appearance of any Indians, intending to question them, through Thalcave, about Captain Grant, as Paganel could not speak to him well enough for this. But the track they were following was one little frequented by the natives, for the ordinary routes across the Pampas lie further north. If by chance some nomadic horseman came in sight far away, he was off again like a dart, not caring to enter into conversation with strangers. To a solitary individual, a little troop of eight men, all mounted and well armed, wore a suspicious aspect, so that any intercourse either with honest men or even banditti, was almost impossible.
