was too dark to notice the striking difference in
complexion and expression. Dr. Grimshaw approached her, keeping his
cloak partially lifted to his face, as if to defend it from the wind,
but probably to conceal it. Then the evil spirit entered Jacquelina, and
tempted her to sidle cautiously up to the professor, slip her arm
through his arm, and whisper:

"Thurston! Come! Jump in the sleigh and go home with us. We shall have
such a nice time! Old Grim has gone to Leonardtown, and won't be home
till to-morrow!"

"Has he, minion? By St. Judas! you are discovered now! I have now full
evidence of your turpitude. By all the saints! you shall answer for it

his arm upon Jacquelina's arm and dragged her toward the sleigh.

"Ha! ha! ha! Oh! well, I don't care! If I mistook you for Thurston, it

creature's person, until she is safely secured."

"You will at least be kind enough to explain to us the causes of your
present words and actions, sir!" said Mrs. Waugh, severely.

"Undoubtedly, madam! Having, as I judged, just reasons for doubting the
integrity of your niece, and more than suspecting her attachment to Mr.
Willcoxen, I was determined to test both. Therefore, instead of going to
Leonardtown, to be absent till to-morrow, I came here, posted myself at
a favorable point for observation, and took notes. While here, I saw
enough to convince me of Jacquelina's indiscretions. Afterward leaving
the spot with lacerated feelings I drew near her. She
