"I think not," he replied, "but it is not unfrequent in the lowlands of Scotland, the south and northwest of England, or the northern parts of Germany. The time of year for its appearance is from the middle of autumn till the beginning of November."

"I think I have read that the people of the districts where it was frequently seen used to be superstitious about it in olden times; and that they called it Will-o'-the-wisp, and Jack-a-lantern."

"Yes; and believed it to be due to the agency of evil spirits who were trying to lure travellers to their destruction. And unfortunately it was sometimes mistaken by unwary travellers for a light, and in trying to reach it, thinking it shone from some human habitation where they might find shelter and a night's lodging, they would follow it and so get into, and sink in, the marsh, thus losing their lives."

"Is it not about time we were seeking our night's lodgings?" asked Mrs. Dinsmore pleasantly, as her husband concluded his sentence. "See, the clock is on the stroke of nine, which is a late enough hour for most of us now, when we are moving about so much during the day. Surely it is for Gracie, whose eyes, I notice, begin to droop."

"I think you are right, my dear," replied her husband. Then he requested Mr. Lilburn to lead their family worship.


CHAPTER XXI.

A few days longer our friends lingered in their pleasant cottages on the beautiful island, loath to leave it, with any one of its many interesting localities unexplored. They walked, rode, drove, and sailed about the bay, visiting now one island, and now another. Captain Raymond's acquaintance with naval and military officers, and his high reputation among them making it easy for them to gain access to vessels, forts, and fortifications.

Goat Island interested them as the place where the English ship Liberty was destroyed before the Revolution. They saw the noble stone pier, hundreds of feet long, visited the torpedo station, and the captain pointed out to the others the curving point on which, more than a century ago, very many pirates had been hanged.
