At nine o'clock, a bright glare became visible, and flames shot up through the darkness. The light was steady and continued.

"That confirms the supposition of a volcano," said Paganel, observing it attentively.

"Yet," replied John Mangles, "at this distance we ought to hear the noise which always accompanies an eruption, and the east wind brings no sound whatever to our ear."

"That's true," said Paganel. "It is a volcano that blazes, but does not speak. The gleam seems intermittent too, sometimes, like that of a lighthouse."

"You are right," said John Mangles, "and yet we are not on a lighted coast."

"Ah!" he exclaimed, "another fire? On the shore this time! Look! It moves! It has changed its place!"

John was not mistaken. A fresh fire had appeared, which seemed to die out now and then, and suddenly flare up again.

"By savages, evidently," replied Paganel.

"But in that case, we cannot leave the quartermaster there."

"No," replied the Major, "he would be too bad a gift even to bestow on savages."
