Let us go."

Truly, the moments were precious. They had to fly. The escape was not very difficult, except the twenty feet of perpendicular fall outside the grotto.

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 passed one by one through the narrow passage 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 grass 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 attitude 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.
