"She came early; by ten o'clock or so, I believe, and she sat, if she did sit, in an observatory they have at the top of the house: a place where she often used to go, I am told, to study astronomy with Professor Darling's oldest daughter."

"And was Miss Darling with her that morning? Did they study together all the time she was in the house?"

"No; that is, the girl said no one went up to the observatory with Miss Dare; that Miss Darling did not happen to be at home that day, and Miss Dare had to study alone. Hearing this," pursued Hickory, answering the look of impatience in the other's face, "I had a curiosity to interview the observatory, and being—well, not a clumsy fellow at softsoaping a girl—I at last succeeded in prevailing upon her to take me up. Byrd, will you believe me when I tell you that we did it without going into the house?"

"What?"

"I mean," corrected the other, "without entering the main part of the building. The professor's house has a tower, you know, at the upper angle toward the woods, and it is in the top of that tower he keeps his telescopes and all that kind of thing. The tower has a special staircase of its own. It is a spiral one, and opens on a door below that connects directly with the garden. We went up these stairs."

"You dared to?"

"Yes; the girl assured me every one was out of the house but the servants, and I believed her. We went up the stairs, entered the observatory——"

"It is not kept locked, then?"

"It was not locked to-day—saw the room, which is a curious one—glanced out over the view, which is well worth seeing, and then——"

"Well, what?"
