At nine o’clock, the night being unusually dark, Glenarvan gave the order to start. His companions and he, armed and equipped at the expense of Kara-Tete, began cautiously to descend the slopes of Maunganamu, John Mangles and Wilson leading the way, eyes and ears on the alert. They stopped at the slightest sound, they started at every passing cloud. They slid rather than walked down the spur, that their figures might be lost in the dark mass of the mountain. At two hundred feet below the summit, John Mangles and his sailors reached the dangerous ridge that had been so obstinately defended by the natives. If by ill luck the Maories, more cunning than the fugitives, had only pretended to retreat; if they were not really duped by the volcanic phenomenon, this was the spot where their presence would be betrayed. Glenarvan could not but shudder, in spite of his confidence, and in spite of the jokes of Paganel. The fate of the whole party would hang in the balance for the ten minutes required to pass along that ridge. He felt the beating of Lady Helena’s heart, as she clung to his arm.
He had no thought of turning back. Neither had John. The young captain, followed closely by the whole party, and protected by the intense darkness, crept along the ridge, stopping when some loose stone rolled to the bottom. If the savages were still in the ambush below, these unusual sounds might provoke from both sides a dangerous fusillade.
But speed was impossible in their serpent-like progress down this sloping crest. When John Mangles had reached the lowest point, he was scarcely twenty-five feet from the plateau, where the natives were encamped the night before, and then the ridge rose again pretty steeply toward a wood for about a quarter of a mile.
All this lower part was crossed without molestation, and they commenced the ascent in silence. The clump of bush was invisible, though they knew it was there, and but for the possibility of an ambush, Glenarvan counted on being safe when the party arrived at that point. But he observed that after this point, they were no longer protected by the taboo. The ascending ridge belonged not to Maunganamu, but to the mountain system of the eastern side of Lake Taupo, so that they had not only pistol shots, but hand-to-hand fighting to fear. For ten minutes, the little band ascended by insensible degrees toward the higher table-land. John could not discern the dark wood, but he knew it ought to be within two hundred feet. Suddenly he stopped; almost retreated. He fancied he heard something in the darkness; his stoppage interrupted the march of those behind.
He remained motionless long enough to alarm his companions. They waited with unspeakable anxiety, wondering if they were doomed to retrace their steps, and return to the summit of Maunganamu.
But John, finding that the noise was not repeated, resumed the ascent of the narrow path of the ridge. Soon they perceived the shadowy outline of the wood showing faintly through the darkness. A few steps more and they were hid from sight in the thick foliage of the trees.
CHAPTER XV FROM PERIL TO SAFETY
THE night favored their escape, and prudence urged them to lose no time in getting away from the fatal neighborhood of Lake Taupo. Paganel took the post of leader, and his wonderful instinct shone out anew in this difficult mountain journey. His nyctalopia was a great advantage, his cat-like sight enabling him to distinguish the smallest object in the deepest gloom.
For three hours they walked on without halting along the far-reaching slope of the eastern side. Paganel kept a little to the southeast, in order to make use of a narrow passage between the Kaimanawa and the Wahiti Ranges, through which the road from Hawkes’ Bay to Auckland passes. Once through that gorge, his plan was to keep off the road, and, under the shelter of the high ranges, march to the coast across the inhabited regions of the province.
