The girls and Miss Alling stared at her in surprise, while even Phrosy stopped groaning long enough to bestow upon her a look of awe.

“Why, Jessie, you didn’t really!” cried Amy, delightedly. “What kind of noise?”

“It was a horrid sound,” said Jessie, slowly. “Like a wailing moan——”

Phrosy let forth another hair-raising shriek and began to rock herself to and fro, hands lifted beseechingly to heaven.

“Dat’s de ghost what Ah heard! Dat’s de ghost what Ah heard?” she chanted over and over, until Miss Alling was forced to silence her and her voice dropped to a wailing monotone.

The girls were wildly excited and even Miss Alling looked worried.

“I don’t know what to say,” she confessed at last, regarding Jessie seriously. “I had supposed that Phrosy’s imagination was running away with her, but if you heard it too, Jessie——”

“It came twice,” said Jessie. “And it was after the second time that Phrosy yelled——”

“Oh! What’s that?”

It was Nell who spoke, and the girls jumped nervously.
