Only one person was awake in all the camp when the doctor and Billie returned: Alberdina, busy ironing pink-tinted clothes in the lean-to. Miss Campbell and the girls were napping on the upper porch and Phoebe still slept on a couch in the living room, while Ben and Percy had not returned from their search for news of her father.

“Miss Billie,” remarked the doctor, “if you will be kind enough to fix me up a lunch, I think I’ll pack my knapsack and start on the road again. I can’t say how long I shall be gone, but you mustn’t be uneasy if I don’t get back for a day or two. The boys will look after you and if you have any real trouble, you had better telegraph your father. If possible, try and keep Phoebe right here. Those men will go no further than threats in regard to us. They know we are too powerful for them, but I couldn’t say the same for that poor girl and her father. I suppose jealousy and Lupo’s treachery are the motives behind it. The father does better work than any of them can do and the mountaineers resent the difference between them, whatever it is, birth, breeding, education. But we can’t judge them by the usual standards, of course. They have never had any chances, these people, shut in by this wall of mountains. There is not much inspiration to be charitable and kind, living in one of these little shanties during the long cold winters. It’s a pretty fine nature that doesn’t get warped and narrowed by the life.”

“Phoebe’s didn’t,” thought Billie, while she sliced bread for the doctor’s lunch.

After he had departed with his staff and his telescope and his knapsack, Billie sat down in a steamer chair under the trees and began to think. She lifted her eyes to the wall of mountains now mystical and unreal under their mantle of blue shadow. How could treachery and hatred and jealousy exist where there was so much beauty? It seemed to her that she had only to look about her to be inspired and uplifted; but Billie was too young to realize that it takes more than scenery to furnish that kind of inspiration.

“I am not tired and I am not sleepy,” she thought. “Must I sit here all the afternoon waiting for the others to wake?” She glanced at her watch. “Only a quarter to three. Why can’t I take a walk? It’s against the rules as laid down by papa for women members, but that was only a joke anyhow and I shan’t go far.”

Billie chose a trail they often took after supper for the reason that it was brought to an early finish by the bed of a creek dry in summer, though probably a brave stream in the spring after the thaws. But it was a pretty walk, tunneled through the forest, carpeted with dried pine needles and bordered on either side by ferns.

Strolling along, Billie thought of many things; of the mountain on the other side of Indian Head on which fires had started and where bands of men were now fighting the flames. That was a dreadful thing to do, to set a forest on fire; a crime against nature as well as against man. She thought of Phoebe’s father, perhaps injured, or worse, who could tell? Then with a mental leap she thought of Richard Hook and his sister Maggie; the charm of their personalities; their simplicity; their joy in living. Billie wondered if she could be happy if she were poor, really quite poor. It was rather fun cooking, with Alberdina to clean up after them. It was only for a little while and it was just a sort of game.

“It would be a dog’s life to keep up forever,” thought Billie, “but Richard and Maggie Hook would never admit it. They make the best of being poor and pretend that living like Gypsies is the most delightful way of spending one’s vacation. I think they are just fine. There is Phoebe, too. How well she has got on without anything, education, money, friends. She is wonderful.”

Who was Phoebe? Who was her father? Were they not mysterious people? When the veil was lifted at last, Billie felt convinced that it would disclose no ordinary identity. They had the marks of distinguished people in exile. There was a look of family about them both that no ragged attire could disguise.

Toward the end of the trail, Billie saw an old woman hobbling toward her, leaning on a stout stick. She looked remarkably like one of the aged forest trees unexpectedly come to life. A gnarled, brown, weather-beaten old creature she was, who reminded Billie of a dwarfed apple tree she had seen in Japan, a little old bent thing said to have been over two hundred years old. Attached to the woman’s waist was a pocket apron bulging with herbs, camomile and catnip, wood sorrel and sassafras root.
