Meantime, Allison and Kitty, hurrying home with their guest, had delighted Norah by a demand for early supper. She and Barbry were expecting some friends from Rollington, a little Irish village near the Valley, and would be glad to be through with their work an hour earlier than usual.
"And you needn't light up for us down-stairs, except in the dining-room," said Allison, "for we're going straight to our rooms after supper, and we don't want to be disturbed till to-morrow morning."
"Very well, miss," answered Barbry, who, a middle-aged woman, was the most trustworthy of well-trained maids. Mrs. Walton never felt any hesitancy in leaving the children in her care.
"And--oh, Barbry," said Allison, as she turned to leave the room. "To-night is Hallowe'en, and they say the witches are out and ghosts rise out of their graves. What is that tale they tell about a ghost that used to be seen about the seminary grounds?"
"Sure, an' your mother would be afther gettin' angry if I filled your heads with such nonsense. Who said there was ever a ghost at all in the Valley?"
But after much teasing Barbry allowed herself to be persuaded into telling a tale that had been afloat for years, of the little woman in gray who had once owned the land on which the seminary was built. She lived all alone, and was an odd character. Her peculiar mode of living, and the mystery surrounding her death, gave rise to the rumour that her spirit still haunted the seminary grounds. It was said that the little woman never appeared in public without a gray veil, and her wraith was recognized by the long gauzy covering floating loosely back from its face, not gray but white, as more becoming a spirit.
No sooner had Barbry finished her tale than Allison beckoned the girls to follow, and led the way up-stairs to the sewing-room. "I thought at first I'd just put a pillow-case over my head and wrap up in a sheet, but I'm going to make the girls think I'm the real article. How will this do?"
Taking a roll of cotton from one of the shelves, she pinned it over her hair to make a short white wig, powdered her face till it was as white as the cotton, and over it all threw a long piece of tulle, which she brought from a bureau drawer in her room. "Aunt Elise gave it to me last time I was in town," she said. "She had yards and yards of it that had been used some way in decorating with lilies for a luncheon. Wait till I wrap a sheet around me. Now how do I look?"
