They had eaten lunch in the dining car, a wonderful experience to the girl, and she promised herself another postal devoted to that, but there was no time to write more after they reached Washington. She was put into a taxi and whirled away to an office where her work began. She caught glimpses of great buildings on the way, and gazed with awe at the dome of the Capitol building. Mr. Barnard was kind and pointed out this and that, but it was plain his mind was on the coming interview. When Shirley sat at last in a quiet corner of a big dark office, her pen poised, her note-book ready for work, and looked at the serious faces of the men in the room, she felt as if she had been rushed through a treasure vault of glorious jewels and thrust into the darkness of a tomb. But presently the talk about her interested her. Things were being said about the vital interests of the country, scraps of sentences that reminded her of the trend of talk in the daily papers, and the headings of front columns. She looked about her with interest and noted the familiarity with which these men quoted the words of those high up in authority in the government. With awe she began her work, taking down whatever Mr. Barnard dictated, her fingers flying over the tiny pages of the note-book, in small neat characters, keeping pace with the voices going on about her. The detail work she was setting down was not of especial interest to her, save that it was concerned with Government work, for its phraseology was familiar and a part of her daily routine office work at home; but she set every sense on the alert to get the tiniest detail and not to make the smallest mistake, understanding from the voices of the men about her that it was of vital interest to the country that this order should be filled quickly and accurately. As she capped her fountain pen, and slipped the rubber band on her note-book when it was over, she heard one of the men just behind her say in a low tone to Mr. Barnard: "You're sure of your secretary of course? I just want to give you the tip that this thing is being very closely watched. We have reason to believe there's some spying planned. Keep your notes carefully and don't let too many in on this. We know pretty well what's going on, but it's not desirable just now to make any arrests until we can watch a little longer and round up the whole party. So keep your eyes peeled, and don't talk." "Oh, certainly! I quite understand," said Mr. Barnard, "and I have a most discreet secretary," and he glanced with a significant smile toward Shirley as she rose. "Of course!" said the other. "She looks it," and he bowed deferentially to Shirley as she passed.
