Three birds in all arose, circled and soared to the eastward while she stood watching. Grace wondered what it could mean, there now being no doubt in her mind that she had witnessed the flight of war pigeons. Returning to the cellar, she awakened Miss Briggs, told her to get up and make the tea, started the fire and went out with the mess kits to fetch their breakfast. Breakfast was rather hurried, as Grace knew she would have to look for the car that she was to drive that morning, and that operation undoubtedly would consume some little time. It did. She was sent from officer to officer before she found the one who was to assign a car to her, and even then she had difficulty in obtaining possession of the vehicle. At last she succeeded in getting it, and lost no time in getting away with the machine before it should be grabbed by some one else. Pulling up before their cellar she jumped out and ran down to assist in loading aboard their belongings. “All aboard for the River Rhine, Elfreda,” she called cheerily. “We are going to enjoy this drive, I know. The air is fine.” “I can’t say as much for the water in this neck of the woods. That water yesterday was beastly. Don’t you dare give me another such a bath, Grace Harlowe,” warned Elfreda. “No, I’m determined to be good to-day and not do a thing to rile our supervisor. You shall see how nice I can be to her. Come, we must get ready.” A few moments later they pulled up before Mrs. Smythe’s cellar and sat waiting for her to appear, after having given a few discreet honks on the horn. When the supervisor emerged with her maid and Miss O’Leary, her face wore a hard expression that had not been there before. Grace, jumping out, opened the car door for her, slammed it shut after the passengers were in, and saluted snappily. “Does not Miss Cahill ride with us to-day?” she questioned. “Carry on as you are!” commanded Mrs. Smythe. “Very good,” answered the Overton girl, climbing to her seat. “Just a moment,” commanded the supervisor. “You are to drive slowly to-day. At the first indication of recklessness or the slightest disobedience of orders I shall call an officer to place you under arrest for insubordination. Do you get me clearly?” “I get you quite clearly, Madame,” answered Grace smilingly. “What speed--three, five, ten, fifteen, twenty, thirty or forty miles?” “You know what I mean. I ordered you to drive slowly.” Grace swung into the highway and started off at a speed of about five miles an hour, but she had not gone far ere the rasping voice of her superior ordered her to drive, not creep. The speed of the car was increased to ten miles an hour, but beyond this the Overton girl would not go, despite the insistent demands of Mrs. Smythe. Finally exasperated beyond measure, Grace stopped the car at the side of the road and faced her supervisor. “Perhaps, Madame, you would prefer to have Miss Briggs drive the car?” “No, thank you,” spoke up Elfreda.
