"Lor', doctor, what's the matter? It's my sister Chloe from 'cross the river. She cum over to see me yes'day, and I'm agwine to take her home."

Dr. Fox surveyed the pretended sister critically, and was inclined to believe the story. The dress, the stuffed form, and general appearance certainly resembled Nancy. But he was not satisfied.

"Are you sure that you haven't got oneof my runaways in the boat with you?" he asked suspiciously.

Nancy's fat sides shook with laughter.

"One of them crazy critters!" she exclaimed. "Chloe, he thinks you're a crazy critter run away from his 'sylum. Won't Dinah laugh when you tell her!"

Mrs. Kenyon possessed an admirable talent for mimicry, though she had not exercised it much of late years. Now, however, the occasion seemed to call for an effort in that direction, and she did not hesitate. She burst into a laugh, rich and hearty, so like Nancy's that the latter was almost startled, as if she heard the echo of her own amusement. No one who heard it would have doubted that it was the laugh of a negro woman.

The laugh convinced Dr. Fox. He no longer entertained any doubt that it was really Nancy's sister.

"It's all right, Nancy," he said apologetically. "I see I am mistaken. If you see either of the runaways let me know," and he turned his horse from the bank.

Not a word passed between Nancy and herpassenger till they had got beyond earshot of the pursuer. Then Nancy began:

"You did dat well, Mis' Kenyon. Ef I hadn't knowed I'd have thought it was ole Chloe herself. Where did you learn dat laugh?"
