“What! make a volcano!” cried John Mangles.

“Yes, an impromptu volcano, whose fury we can regulate. There are plenty of vapors ready to hand, and subterranean fires ready to issue forth. We can have an eruption ready to order.”

“An excellent idea, Paganel; well conceived,” said the Major.

“You understand,” replied the geographer, “we are to pretend to fall victims to the flames of the Maori Pluto, and to disappear spiritually into the tomb of Kara-Tete. And stay there three, four, even five days if necessary—that is to say, till the savages are convinced that we have perished, and abandon their watch.”

“But,” said Miss Grant, “suppose they wish to be sure of our punishment, and climb up here to see?”

“No, my dear Mary,” returned Paganel. “They will not do that. The mountain is tabooed, and if it devoured its sacrilegious intruders, it would only be more inviolably tabooed.”

“It is really a very clever plan,” said Glenarvan. “There is only one chance against it; that is, if the savages prolong their watch at the foot of Maunganamu, we may run short of provisions. But if we play our game well there is not much fear of that.”

“And when shall we try this last chance?” asked Lady Helena.

“To-night,” rejoined Paganel, “when the darkness is the deepest.”

“Agreed,” said McNabbs; “Paganel, you are a genius! and I, who seldom get up an enthusiasm, I answer for the success of your plan. Oh! those villains! They shall have a little miracle that will put off their conversion for another century. I hope the missionaries will forgive us.”
