"If you will allow me to do exactly what I like," said Mary, "I don't want anyone to guide me; I want to wander here, there, and everywhere just at my own sweet will.  I have brought my little sketch-book with me, and mean to sketch some of these splendid old trees.  Mother is so fond of outdoor sketches, and I could seldom indulge her with anything so fine as I could get in an old place like this.  Just go off where you please, girls, and don't bother about me."
