Mavis had to follow her. There was not much fear of Ruby’s really doing anything rash, for she was by no means a very brave child, still Mavis always felt uncomfortable when her sister got into one of these wild moods.

“Good-bye, Joan,” she said gently. “I’m so glad baby’s better. I daresay Ruby’s only joking;” and then she ran along the path, which just here in the hamlet was pretty level and smooth, after Ruby.

They had quite half a mile to go before they got to the lonely cottage. It stood some way back from the shore, and great craggy rocks near at hand almost hid it from sight. One might have passed by that way often without noticing that there was any human dwelling-place there. But the children were on the look-out.

“There,” said Ruby, “the old ogre can’t be dead: there’s smoke coming out of the chimney. And—oh, just look, Mavis, what a big fire he must have; do you see the red of it in the window?”

“No,” said Mavis, “it’s the sun setting. Look out to sea—isn’t it splendid?”

But Ruby had set her heart upon exploring the fisherman’s hut. She began scrambling up the stones, for there was really nothing worthy of the name of a pathway, quite regardless of the beautiful sight behind her. And as usual. Mavis had to follow, though reluctantly. Still she was not quite without curiosity about the lonely cottage herself. Suddenly, when within a short distance of the hut, Ruby stopped short, and glancing back towards her sister, lifted her hand as if to tell her to be silent and listen. Then Mavis became conscious of the sound of voices speaking—not old Adam’s voice certainly, for these sounded soft and clear, and now and then came a ripple of silvery laughter, very sweet and very delicate. The little girls, who had drawn near together, looked at each other.

“Who can it be?” said Mavis in a whisper.

“The mermaids,” replied Ruby mockingly. “Perhaps old Adam has invited them to tea.”

But as she spoke there came distinctly the sound of the words “Good-bye, good-bye,” and then there was silence.

Somehow both children felt rather frightened. “Suppose old Adam’s really dead,” said Ruby, looking rather pale, “and that these are—fairies, or I don’t know what, come to fetch him.”
