iss this one too."

"Well, there is a chance you shouldn't miss," said Miss Morris,
pointing and nodding her head. "There she is now, and all alone.
She's sketching, isn't she, or taking notes? What is she doing?"

Carlton looked eagerly in the direction Miss Morris had signified, and
saw the Princess Aline sitting at some distance from them, with a book
on her lap. She glanced up from this now and again to look at
something ahead of her, and was apparently deeply absorbed in her
occupation.

"There is your opportunity," said Mrs. Downs; "and we are going back to
the hotel. Shall we see you at luncheon?"

"Yes," said Carlton, "unless I get a position as drawing-master; in
that case I shall be here teaching the three amateurs in art. Do you
think I can do it?" he asked Miss Morris.

"Decidedly," she answered. "I have found you a most educational young

They went away together, and Carlton moved cautiously towards the spot

as he did so, in order to keep himself behind her. He did not mean to
come so near that she would see him, but he took a certain satisfaction

taking alarm at once. "If it would only prove to be some one who meant
harm to her," he thought--"a brigand, or a beggar, who might be
obligingly insolent, or even a tipsy man, what a chance it would afford
for heroic action!"

With this hope he moved forward quickly but silently, hoping that the
stranger might prove even to be an anarchist with a grudge against
royalty. And as he advanced he had the satisfaction of seeing the
Princess glance over her shoulder, and, observing the man, rise and
walk quickly away towards the edge of the rock. There she seated
herself with her face towards the city, and with her back firmly set
against her pursuer.

"He is annoying her!" exclaimed Carlton, delightedly, as he hurried
forward. "It looks as though my chan
