“When I see her—well, I’m going to see her now.” The doctor looked down at Nathalie keenly. “If you are willing to give this pleasure suppose you begin to-day?”

“Why, well, yes, I suppose I could go this morning.” Nathalie wrinkled her brows; she was wondering about dinner. “All right,” she said in a moment, “I’ll tell Mother and get my hat!” She started for the door.

“Just wait a moment!” commanded the doctor suddenly, taking Nathalie by the arm and peering down into her face with intent eyes. “I forgot something, for amusing this little girl means that you will have to promise two things.”

“What are they?” asked the girl curiously.

“The first one is that you will have to promise—as a Girl Pioneer—” the doctor’s eyes gleamed again “not to betray to a living soul that you are telling stories to this child; there is a reason.”

“Oh, that is easy,” nodded Nathalie; “that is, if you except Mamma, for I always tell everything to her.”

“Well, we’ll trust Mrs. Page as to secrecy, and the next thing—this is a big promise, for it will not be so easy to keep—is that when you go to this lady’s house you will consent to be blindfolded.” The doctor looked relieved.
