"I was going to say," she explained, "that we must devise a partition. There is no help for it until you construct a sort of house. Candidly, I do not like this hole in the rock. It is a vault, a tomb."
"You told me that I was in command, yet you dispute my orders." He strove hard to appear brusquely good-humored, indifferent, though for one of his mould he was absurdly irritable. The cause was over-strain, but that explanation escaped him.
"Quite true. But if sleeping in the cold, in dew or rain, is bad for me, it must be equally bad for you. And without you I am helpless, you know."
His arms twitched to give her a reassuring hug. In some respects she was so childlike; her big blue eyes were so ingenuous. He laughed sardonically, and the harsh note clashed with her frank candor. Here, at least, she was utterly deceived. His changeful moods were incomprehensible.
"I will serve you to the best of my ability, Miss Deane," he exclaimed. "We must hope for a speedy rescue, and I am inured to exposure. It is otherwise with you. Are you ready for the climb?"
Mechanically she picked up a stick at her feet. It was the sailor's wand of investigation. He snatched it from her hands and threw it away among the trees.
"That is a dangerous alpenstock," he said. "The wood is unreliable. It might break. I will cut you a better one," and he swung the axe against a tall sapling.
Iris mentally described him as "funny." She followed him in the upward curve of the ascent, for the grade was not difficult and the ground smooth enough, the storms of years having pulverized the rock and driven sand into its clefts. The persistent inroads of the trees had done the rest. Beyond the flight of birds and the scampering of some tiny monkeys overhead, they did not disturb a living creature.
The crest of the hill was tree-covered, and they could see nothing beyond their immediate locality until the sailor found a point higher than the rest, where a rugged collection of hard basalt and the uprooting of some poon trees provided an open space elevated above the ridge.
For a short distance the foothold was precarious. Jenks helped the girl in this part of the climb. His strong, gentle grasp gave her confidence. She was flushed with exertion when they stood together on the summit of this elevated perch. They could look to every point of the compass except a small section on the south-west. Here the trees rose behind them until the brow of the precipice was reached.
