It was arduous work, for the ground was rapidly rising; but they were forced to hurry along, for every time they halted, they could hear the shouts of their pursuers, who seemed to be coming on with a pertinacity that there was no shaking off.
It was hot in the extreme, but a crisp, cool air was blowing to refresh them, and, of its kind, there was plenty of food, Ngati cautiously picking and breaking in places where the disarrangement was not likely to be seen. Every now and then, too, they saw him make quite an eager dash on one side and return with eggs, which he carefully placed in the woven bag he had made.
This went on till he had nearly a couple of dozen, at which, as he trudged along, Jem kept casting longing eyes.
In spite of the danger and weariness, Don could not help admiring the beauty of the scene, as, from time to time, the gully opened out sufficiently for him to see that they were steadily rising toward a fine cone, which stood up high above a cluster of mountains, the silvery cloud that floated from its summit telling plainly of its volcanic nature.
“Tapu! tapu!” Ngati said, every time he saw Don gazing at the mountain; but it was not till long after that he comprehended the meaning of the chiefs words, that the place was “tapu,” or sacred, and that it would act as a refuge for them, could they reach it, as the ordinary Maoris would not dare to follow them there.
Higher up the valley, where the waters were dashing furiously down in many a cascade, Don began to realise that they were following the bed of a river, whose source was somewhere high up the mountain he kept on seeing from time to time, while, after several hours’ climbing, often over the most arduous, rocky ground, he saw that they were once more entering upon a volcanic district. Pillars of steam rose here and there, and all at once he started aside as a gurgling noise arose from beyond a patch of vivid green which covered the edges of a mud-pool, so hot that it was painful to the hand.
From time to time Ngati had stopped to listen, the shouts growing fainter each time, while, as they progressed, a heavy thunderous roar grew louder, died away, and grew louder again.
Don looked inquiringly at Jem.
“It’s the big chimney of that mountain drawing, Mas’ Don.”
“Nonsense!”
