"Now, Estralla, if you love Miss Sylvia, if you want to stay with your mammy, you must never tell of her visit here to-night. Remember!" and Mr. Doane's voice was very stern.

"Estralla won't tell," Sylvia declared confidently; "and I am glad she came to go home with me."

"Shuah I'll do jes' what Missy wants me to," said the little darky.

"Try to let Mrs. Carleton know that I received the letter, and that I hope to reach Washington safely," said Mr. Doane, as he bade Sylvia good-night.

As the door closed behind them Estralla clasped Sylvia's hand.

"Wat dat clock say?" she asked; for one of the city clocks was striking the hour.

"It's twelve o'clock," answered Sylvia.

"Oh! My lan', Missy! Dat's a terrible onlucky time fer us to be out," whispered Estralla. "Dat's de time w'en witch folks comes a-dancin' an' a-prancin' 'roun' and takes off chilluns."

Sylvia knew that all the negroes believed in witches and all sorts of impossible tales, so Estralla's words did not at all frighten her, but she did wish that she was safe in her own home. The streets were now dark and silent, and black shadows seemed to lurk at every corner as, hand in hand, Estralla and Sylvia ran swiftly along.

"I tells you, Missy, dat it's jes' lucky I comes after you, cos' witch-folks, w'at comes floatin' 'roun' 'bout dis hour of de night, dey ain't gwine to tech us; cos' when dey's two folks holdin' each other hands tight, jes' like we is, dey don't dast to tech us," said Estralla.
