"Oh!" exclaimed Sylvia with such surprise that the little darky looked at her wonderingly.

"Yo' tells me to come, an' here I is," she repeated. "You tells me," and Estralla sniffed as if ready to give her usual wails, "that you'se gwine to stop my bein' sold off from my mammy. How you gwine to stop it, Missy?"

For a moment Sylvia was tempted to tell Estralla that it couldn't be helped, as long as South Carolina believed in slavery. But Estralla's sad eyes and pleading look made her resolve again to protect this little slave girl against injustice. So she replied quickly:

"That is my secret. But don't you worry. Some day, very soon, I shall tell you all about it. You know, Estralla, that you need not be afraid. And what do you think! I am not going to school any more."

Estralla's face had brightened. She was always quite ready to smile, but she could not understand why Sylvia had wanted her to come so mysteriously to her room.

"And I am going to teach you to read and write," Sylvia added.

"Is you, Missy?" Estralla responded in a half-frightened whisper. Now, she thought, she knew all about Missy Sylvia's reasons for the secret visit. For very few slave-owners allowed anyone to teach the slaves to read and write. Estralla knew this, and it seemed a wonderful thing that Missy Sylvia proposed.

"I'll tell you all about it to-morrow morning," said Sylvia; "now run away," and with a chuckle of delight Estralla closed the door softly behind her. She had been quite ready to run away with Missy Sylvia when she had crept up the stairs earlier in the evening. But to stay safely with her mammy and learn to read seemed a much happier plan to the little darky. If she could read and write! Why, it would be almost as wonderful as it would to be a little white girl, she thought.

Now Sylvia realized, as she stood alone in her safe, pleasant chamber, that as soon as possible she must deliver the letter entrusted to her. If it was to go to Washington it must be some message that was of importance to the officers at Fort Moultrie and Fort Sumter, she thought. Perhaps it might even be something that would help Carolinians to give up slavery; and then Estralla and Aunt Connie, and all the black people she knew and liked, could be safe and have homes of their own.

Sylvia went to the window and peered out. The street and garden lay dark and shadowy. Now and then a dark figure went along the street. The house seemed very quiet. She tiptoed to the closet and took out a brown cape. It was one which she wore on stormy days, and nearly covered her. Then from one of the bureau drawers she drew out a long blue silk scarf, and twisted it about her head.
