She and Mr. Keith exchanged looks when the latter entered the room. Keith raised his eyebrows inquiringly. She nodded as if giving emphatic assent to his unspoken question.

Shadrach and Mary-'Gusta left the house soon afterward. While the Captain and Mr. Keith were whispering together in the hall, Mrs. Wyeth bade the girl good-by.

“I like you, my dear,” said the lady. “You seem to be a sweet, sensible girl, and I don't meet as many of that kind nowadays as I could wish. I am sure we shall be good friends.”

“And WHAT did she mean by that?” demanded Mary-'Gusta, as she and the Captain walked along Pinckney Street together. “Why should we be good friends? Probably I'll never meet her again.”

Shadrach smiled. “Oh, you can't always tell,” he said. “Sometimes you meet folks oftener'n you think in this world.”

Mary-'Gusta looked at him. “Uncle Shad,” she said, “what does all this mean, anyway? Why did you go to her house? And what was the mysterious business of yours with Mr. Keith?”

The Captain shook his head. “We've got a hen on, same as I told you,” he declared. “When it's time for the critter to come off the nest you'll see what's been hatched same as the rest of us. How'd you like that Mrs. Wyeth? Had a pretty sharp edge on her tongue, didn't she?”

Mary-'Gusta considered. “Yes,” she answered; “she was outspoken and blunt, of course. But she is a lady—a real lady, I think—and I'm sure I should like her very much when I knew her better. I think, though, that she would expect a person to behave—behave in her way, I mean.”

“Judas! I should say so. Don't talk! I ain't felt so much as if I was keepin' my toes on a chalk mark since I went to school. I don't know what her husband died of, but I'll bet 'twasn't curvature of the spine. If he didn't stand up straight 'twasn't his wife's fault.”

Mary-'Gusta's curiosity concerning the mysterious business which had brought them to the city became greater than ever before it was time to take the train for home. Apparently all of that business, whatever it might be, had been transacted when her uncle and Mr. Keith took their short walk together after luncheon. Captain Shadrach seemed to consider his Boston errand done and the pair spent half of the hour before train time wandering along Tremont and Washington Streets looking into shop windows, and the other half in the waiting room of the South Station.
