After that the slope was practicable to the foot of the mountain. From this point the prisoners could soon gain the lower valleys; while the Maories, if they perceived the flight of the prisoners, would have to make a long round to catch them, being unaware of the gallery between the Ware-Atoua and the outer rock.

The escape was commenced, and every precaution was taken. The captives pa.s.sed one by one through the narrow pa.s.sage into the grotto. John Mangles, before leaving the hut, disposed of all the evidences of their work, and in his turn slipped through the opening and let down over it the mats of the house, so that the entrance to the gallery was quite concealed.

The next thing was to descend the vertical wall to the slope below, and this would have been impracticable, but that Robert had brought the flax rope, which was now unrolled and fixed to a projecting point of rock, the end hanging over.

John Mangles, before his friends trusted themselves to this flax rope, tried it; he did not think it very strong; and it was of importance not to risk themselves imprudently, as a fall would be fatal.

"This rope," said he, "will only bear the weight of two persons; therefore let us go in rotation. Lord and Lady Glenarvan first; when they arrive at the bottom, three pulls at the rope will be a signal to us to follow."

"I will go first," said Robert. "I discovered a deep hollow at the foot of the slope where those who come down can conceal themselves and wait for the rest."

"Go, my boy," said Glenarvan, pressing Robert's hand.

Robert disappeared through the opening out of the grotto. A minute after, the three pulls at the cord informed them the boy had alighted safely.

Glenarvan and Lady Helena immediately ventured out of the grotto. The darkness was still very great, though some grayish streaks were already visible on the eastern summits.

The biting cold of the morning revived the poor young lady. She felt stronger and commenced her perilous descent.

Glenarvan first, then Lady Helena, let themselves down along the rope, till they came to the spot where the perpendicular wall met the top of the slope. Then Glenarvan going first and supporting his wife, began to descend backward.

He felt for the tufts and gra.s.s and shrubs able to afford a foothold; tried them and then placed Lady Helena's foot on them. Some birds, suddenly awakened, flew away, uttering feeble cries, and the fugitives trembled when a stone loosened from its bed rolled to the foot of the mountain.

They had reached half-way down the slope, when a voice was heard from the opening of the grotto.

"Stop!" whispered John Mangles.

Glenarvan, holding with one hand to a tuft of tetragonia, with the other holding his wife, waited with breathless anxiety.

Wilson had had an alarm. Having heard some unusual noise outside the Ware-Atoua, he went back into the hut and watched the Maories from behind the mat. At a sign from him, John stopped Glenarvan.

One of the warriors on guard, startled by an unusual sound, rose and drew nearer to the Ware-Atoua. He stood still about two paces from the hut and listened with his head bent forward. He remained in that att.i.tude for a minute that seemed an hour, his ear intent, his eye peering into the darkness. Then shaking his head like one who sees he is mistaken, he went back to his companions, took an armful of dead wood, and threw it into the smouldering fire, which immediately revived. His face was lighted up by the flame, and was free from any look of doubt, and after having glanced to where the first light of dawn whitened the eastern sky, stretched himself near the fire to warm his stiffened limbs.

"All's well!" whispered Wilson.

John signaled to Glenarvan to resume his descent.

Glenarvan let himself gently down the slope; soon Lady Helena and he landed on the narrow track where Robert waited for them.

The rope was shaken three times, and in his turn John Mangles, preceding Mary Grant, followed in the dangerous route.

He arrived safely; he rejoined Lord and Lady Glenarvan in the hollow mentioned by Robert.

Five minutes after, all the fugitives had safely escaped from the Ware-Atoua, left their retreat, and keeping away from the inhabited sh.o.r.es of the lakes, they plunged by narrow paths into the recesses of the mountains.

They walked quickly, trying to avoid the points where they might be seen from the pah. They were quite silent, and glided among the bushes like shadows. Whither? Where chance led them, but at any rate they were free.

Toward five o'clock, the day began to dawn, bluish clouds marbled the upper stratum of clouds. The misty summits began to pierce the morning mists. The orb of day was soon to appear, and instead of giving the signal for their execution, would, on the contrary, announce their flight.

It was of vital importance that before the decisive moment arrived they should put themselves beyond the reach of the savages, so as to put them off their track. But their progress was slow, for the paths were steep.

Lady Glenarvan climbed the slopes, supported, not to say carried, by Glenarvan, and Mary Grant leaned on the arm of John Mangles; Robert, radiant with joy, triumphant at his success, led the march, and the two sailors brought up the rear.

Another half an hour and the glorious sun would rise out of the mists of the horizon. For half an hour the fugitives walked on as chance led them. Paganel was not there to take the lead. He was now the object of their anxiety, and whose absence was a black shadow between them and their happiness. But they bore steadily eastward, as much as possible, and faced the gorgeous morning light. Soon they had reached a height of 500 feet above Lake Taupo, and the cold of the morning, increased by the alt.i.tude, was very keen. Dim outlines of hills and mountains rose behind one another; but Glenarvan only thought how best to get lost among them.

Time enough by and by to see about escaping from the labyrinth.

At last the sun appeared and sent his first rays on their path.

Suddenly a terrific yell from a hundred throats rent the air. It came from the pah, whose direction Glenarvan did not know. Besides, a thick veil of fog, which, spread at his feet, prevented any distinct view of the valleys below.

But the fugitives could not doubt that their escape had been discovered; and now the question was, would they be able to elude pursuit? Had they been seen? Would not their track betray them?

At this moment the fog in the valley lifted, and enveloped them for a moment in a damp mist, and at three hundred feet below they perceived the swarming ma.s.s of frantic natives.

While they looked they were seen. Renewed howls broke forth, mingled with the barking of dogs, and the whole tribe, after vainly trying to scale the rock of Ware-Atoua, rushed out of the pah, and hastened by the shortest paths in pursuit of the prisoners who were flying from their vengeance.

CHAPTER XIII THE SACRED MOUNTAIN

THE summit of the mountain was still a hundred feet above them. The fugitives were anxious to reach it that they might continue their flight on the eastern slope out of the view of their pursuers. They hoped then to find some practicable ridge that would allow of a pa.s.sage to the neighboring peaks that were thrown together in an orographic maze, to which poor Paganel's genius would doubtless have found the clew.

They hastened up the slope, spurred on by the loud cries that drew nearer and nearer. The avenging crowd had already reached the foot of the mountain.

"Courage! my friends," cried Glenarvan, urging his companions by voice and look.

In less than five minutes they were at the top of the mountain, and then they turned to judge of their position, and decide on a route that would baffle their pursuers.

From their elevated position they could see over Lake Taupo, which stretched toward the west in its setting of picturesque mountains. On the north the peaks of Pirongia; on the south the burning crater of Tongariro. But eastward nothing but the rocky barrier of peaks and ridges that formed the Wahiti ranges, the great chain whose unbroken links stretch from the East Cape to Cook's Straits. They had no alternative but to descend the opposite slope and enter the narrow gorges, uncertain whether any outlet existed.

Glenarvan could not prolong the halt for a moment. Wearied as they might be, they must fly or be discovered.

"Let us go down!" cried he, "before our pa.s.sage is cut off."

But just as the ladies had risen with a despairing effort, McNabbs stopped them and said:

"Glenarvan, it is useless. Look!"

And then they all perceived the inexplicable change that had taken place in the movements of the Maories.

Their pursuit had suddenly stopped. The ascent of the mountain had ceased by an imperious command. The natives had paused in their career, and surged like the sea waves against an opposing rock. All the crowd, thirsting for blood, stood at the foot of the mountain yelling and gesticulating, brandishing guns and hatchets, but not advancing a foot.

Their dogs, rooted to the spot like themselves, barked with rage.

What stayed them? What occult power controlled these savages? The fugitives looked without understanding, fearing lest the charm that enchained Kai-Koumou's tribe should be broken.

Suddenly John Mangles uttered an exclamation which attracted the attention of his companions. He pointed to a little inclosure on the summit of the cone.

"The tomb of Kara-Tete!" said Robert.
