Protest, entreaty, expostulation, were alike vain. Even when Tommy, with an air of triumph, exclaimed, "The hole isn't big enough for you to squeeze through," Elizabeth simply replied, "Then we must make it bigger."
Tommy knew from old experience that her elder sister was rather slow to make up her mind about anything; but when it was made up nothing would turn her. Some people called it firmness, I dare say there was a touch of obstinacy as well. It was evident that Elizabeth was thoroughly determined now, and the younger girls at length desisted from their attempts to dissuade her, and agreed to help.
Leaving Mary to assist Maku and Fangati in constructing a light ladder from the creepers she had gathered, Elizabeth set off with Tommy to return to the cave end of the tunnel. They had their knives with them. On arriving at the hole, they saw that the natives were still asleep, and several of the torches were almost burnt out. The dimmer light favoured their work of enlarging the hole, which, as Tommy had said, was too narrow by several inches for Elizabeth to pass through, still less the rescued prisoner.
When Elizabeth said that the hole must be made bigger, she had no definite knowledge whether it was possible. It was characteristic of her to form a resolution and then bend everything towards its accomplishment. If she had had a favourite motto it would have been "Where there's a will there's a way." Nevertheless, it was with some anxiety that she examined the hole. One side of it was solid rock; it would be a week's work to make any impression on it with their knives. But the other side was of a more friable character. It appeared to be formed of fragments that had settled down, and become compacted by the weight above. A tentative chipping at this with her knife showed Elizabeth that it would not be a difficult matter to scrape away enough to enlarge the hole by more than a foot.
There was danger in the task. Work as carefully as they might, it would be impossible to prevent some of the chips and dust from dropping into the cave. Luckily, none of the sleepers was immediately beneath the hole; and Elizabeth thought that by working carefully, collecting the larger chips and placing them on the floor of the tunnel, they might obviate the risk of awakening the men by the noise of falling stones.
