As Elizabeth lay in her berth, musing pleasantly over the events of the evening, it occurred to her that Mr. Adams had left a number of openings into which it would have been easy for her to step with some remark about herself or her work, which would have revealed her vocation.  She had not done so merely because something else which she wanted to say had happened, each time, to come into her mind.  Thinking it over, she remembered so many such openings that it seemed as if they must have been made with intent.  She wondered if he had been trying to find out her occupation, and smiled gleefully.

“If that’s what he wants to know,” she thought, “I ’ll give him an interesting time to-morrow trying to find out.  I wonder if he and his friend have made a wager about what my profession is.  Very likely.  Well, he ’s a good talker and interesting enough to help pass the time; and if he wants to try again to-morrow, I ’ll be at home in this section until we reach Chicago.”

The next morning, with the excuse of some trivial attention to her comfort, Adams came again to Elizabeth’s seat and they were soon talking as interestedly as on the previous evening.  A piece of news in the morning paper gave him opportunity to turn the conversation upon the profession of teaching for women and he talked of the noble work for the public good which women do in that way.  Elizabeth listened with a little gleam in the corner of her eye, agreed with him warmly and spoke with enthusiasm of her own indebtedness to some of those under whom she had studied.

Then Adams dwelt on the widening opportunities for work and self-expression which women have nowadays, and said he thought that the profession of medicine was one for which women were well fitted, and that he was not surprised that so many women found in it congenial work and marked success.  With some effort Elizabeth kept her face very serious and doubted if the profession was one for which any but the most exceptional women were suited, and, on the whole, was inclined to think that if she were very ill she would rather call a man than a woman physician.  He led the talk on to other occupations in which women engage, and some Elizabeth praised and others deprecated as vocations for her sex.  But not once did she give any indication that they had touched upon her own kind of work.  Adams looked puzzled and Elizabeth concealed behind her handkerchief a smile which she was not able to repress.

“I wonder what it can be,” he thought.  “She surely does something.  The expression of her face, her intelligence, and her interest in all kinds of things tell that very plainly.  I wish Chicago were not so near.  She ’s an extremely interesting woman.”

“I suppose I shall soon have to bid you good-bye,” he said, as they neared the station in Chicago.  “I have enjoyed our brief acquaintance very much, and if I can be of any assistance to you in Chicago I shall be glad to do so.  I am going farther west, to California, on the Santa Fe line, but as my train does not leave at once I shall have some time to spare.”
