It was fully fifteen minutes before Agatha returned, book in hand. Irene glanced at the title and gave a sigh of relief. Without comment their guest resumed her seat and soon appeared to be immersed in her volume. Gradually the sun crossed the mountain and cast a black shadow over the plain below, a shadow which lengthened and advanced inch by inch until it shrouded the landscape spread beneath them.
"That is my sun-dial," remarked Mary Louise, dropping her needlework to watch the shifting scene. "When the shadow passes the Huddle, it's four o'clock; by the time it reaches that group of oaks, it is four-thirty; at five o'clock it touches the creek, and then I know it's time to help Aunt Hannah with the dinner."
Agatha laughed.
"Is it really so late?" she asked. "I see the shadow has nearly reached the brook."
"Oh! I didn't mean—"
"Of course not; but it's time I ran home, just the same. My maid Susan is a perfect tyrant and scolds me dreadfully if I'm late. May I take this book home, Irene? I'll return the others I have borrowed to-morrow."
"To be sure," answered Irene. "I'm rich in books, you know."
When Miss Lord went away the party broke up, for Aunt Hannah was already thinking of dinner and Mary Louise wanted to make one of Uncle Peter's favorite desserts. So Irene wheeled her chair into the house and entering the den began a sharp inspection of the place, having in mind exactly the way it had looked when last she left it. But presently she breathed a sigh of relief and went into her own room, for the den had not been disturbed. She wheeled herself to a small table in a corner of her chamber and one glance confirmed her suspicions.
For half an hour she sat quietly thinking, considering many things that might prove very important in the near future. The chair-girl knew little of life save what she had gleaned from books, but in some ways that was quite equal to personal experiences. At dinner she asked:
"Did you take a book from my room to-day, Mary Louise?"
