"That is a good idea! My friends, do you know what those creatures use for wads?"

"No, Paganel!" said Glenarvan.

"Pages of the Bible! If that is the use they make of the Holy Book, I pity the missionaries! It will be rather difficult to establish a Maori library."

"And what text of scripture did they aim at us?"

"A message from God Himself!" exclaimed John Mangles, who was in the act of reading the scorched fragment of paper. "It bids us hope in Him," added the young captain, firm in the faith of his Scotch convictions.

"Read it, John!" said Glenarvan.

And John read what the powder had left visible: "I will deliver him, for he hath trusted in me."

"My friends," said Glenarvan, "we must carry these words of hope to our dear, brave ladies. The sound will bring comfort to their hearts."

Glenarvan and his companions hastened up the steep path to the cone, and went toward the tomb. As they climbed they were astonished to perceive every few moments a kind of vibration in the soil. It was not a movement like earthquake, but that peculiar tremor that affects the metal of a boiler under high pressure. It was clear the mountain was the outer covering of a body of vapor, the product of subterranean fires.

This phenomenon of course excited no surprise in those that had just traveled among the hot springs of the Waikato. They knew that the central region of the Ika-na-Mani is essentially volcanic. It is a sieve, whose interstices furnish a passage for the earth's vapors in the shape of boiling geysers and solfataras.

Paganel, who had already noticed this, called the attention of his friends to the volcanic nature of the mountain. The peak of Maunganamu was only one of the many cones which bristle on this part of the island. It was a volcano of the future. A slight mechanical change would produce a crater of eruption in these slopes, which consisted merely of whitish silicious tufa.

"That may be," said Glenarvan, "but we are in no more danger here than standing by the boiler of the DUNCAN; this solid crust is like sheet iron."

"I agree with you," added the Major, "but however good a boiler may be, it bursts at last after too long service."

"McNabbs," said Paganel, "I have no fancy for staying on the cone. When Providence points out a way, I will go at once."

"I wish," remarked John, "that Maunganamu could carry us himself, with all the motive power that he has inside. It is too bad that millions of horse-power should lie under our feet unavailable for our needs. Our DUNCAN would carry us to the end of the world with the thousandth part of it."

The recollections of the DUNCAN evoked by John Mangles turned Glenarvan's thoughts into their saddest channel; for desperate as his own case was he often forgot it, in vain regret at the fate of his crew.

His mind still dwelt on it when he reached the summit of Maunganamu and met his companions in misfortune.

Lady Helena, when she saw Glenarvan, came forward to meet him.

"Dear Edward," said she, "you have made up your mind? Are we to hope or fear?"

"Hope, my dear Helena," replied Glenarvan. "The natives will never set foot on the mountain, and we shall have time to devise a plan of escape."

"More than that, madam, God himself has encouraged us to hope."

And so saying, John Mangles handed to Lady Helena the fragment of paper on which was legible the sacred words; and these young women, whose trusting hearts were always open to observe Providential interpositions, read in these words an indisputable sign of salvation.

"And now let us go to the 'oudoupa!'" cried Paganel, in his gayest mood. "It is our castle, our dining-room, our study! None can meddle with us there! Ladies! allow me to do the honors of this charming abode."

They followed Paganel, and when the savages saw them profaning anew the tabooed burial place, they renewed their fire and their fearful yells, the one as loud as the other. But fortunately the balls fell short of our friends, though the cries reached them.
