Walter stood some minutes leaning against the wall, striving to recall some favorite song that had often served them upon those occasions. Al length, suddenly exclaiming, "I have it," he began in a low tone to sing,—
"Where have you been all this day,
Bonnie laddie, Highland laddie,
From your hills so far away,
My bonny Highland laddie?"
Instantly, in the same cautious tone, came through the grates the succeeding stanza,—
"Donald's been to Aberdeen,
Bonnie lassie, Highland lassie,
To see de duke in his Highland green,
My bonnie Highland lassie."
