It was a delightful go-as-you-please picnic. Babe went wading in a pool after sea-anemones. Betty lay on a sunny slope dreaming of all the good times she had been having and was going to have all summer. Madeline and Mr. Dwight sat on the parapet and quarreled amicably over the right way to “lay” a signal-fire. Babbie and John conducted Mrs. Hildreth over the castle domain, and when she was tired they decorated the tea-table--a slab of rock on a sunny slope by the sea--with sprays of white heather, which is supposed always to bring good luck to those who wear it. After tea they all sat together watching the sunset, while Madeline told them a quaint folk-tale that an old grannie at the farmhouse had told her, all about ghosts and fairies and gnomes who lived on the islands in the firth.
