Famous quotes containing the word mary:
“He was high and mighty. But the kindest creature to his slaves—and the unfortunate results of his bad ways were not sold, had not to jump over ice blocks. They were kept in full view and provided for handsomely in his will. His wife and daughters in the might of their purity and innocence are supposed never to dream of what is as plain before their eyes as the sunlight, and they play their parts of unsuspecting angels to the letter.”
