"Grace, I've got to do something!" she burst out at last, gripping the wheel so tightly her knuckles showed white. "It isn't so much the valuable time we're losing, but it's an absolute necessity to show that fellow where he--" "'Where he gets off,'" Grace finished slangily. "I know dear, but how?" Betty shook her head helplessly and just glared. Then suddenly Grace uttered a little cry and sat up straight in her seat. "I have it!" she cried. "I know what we can do." "Tell me," demanded Betty. "Why, I know this road pretty well," Grace explained, speaking quickly. "We're not much more than ten miles from Bluff Point." "Yes, yes," cried Betty impatiently. "Well, there is a short detour road that juts off from the main road just a little further on, and after running parallel to the road for half a mile or so, crosses it again." "Yes," cried Betty again, beginning to understand the plot. "So we'll take the detour," Grace finished triumphantly, "and come out, in front of the farmer." "And then--" said Betty with a chuckle and a gleam in her eye. "The rest will be up to us," finished Grace. "Shall we know what to do then?" "I'll say we shall," chortled Betty, adding with a glance over her shoulder at Mollie's car that was creeping along some twenty feet behind them: "Of course the next thing will be to tell Mollie. Will you run back Grace?" For once Grace did not object, and without waiting for Betty to stop the car, and indeed it was hardly necessary at the rate they were going, jumped out and ran back, waving an excited hand at Mollie. Betty heard a whoop of delight from the rear, and in a minute Grace was back in her place. "How far is it from here?" asked Betty, scanning the road ahead eagerly. "I hope," she added, as a horrid fear assailed her, "that he doesn't turn off on to the other road, too." "Heavens, I hope not! Oh, there it is!" she cried a moment later, as a turn in the winding road brought the crossroads to view. "Now, if he only doesn't turn down it!" Eagerly they watched and drew a sigh of relief as the driver jogged steadily on down the main road. "Now's our chance," exulted Betty, as she changed gears with a challenging roar and slipped off merrily down the detour road. Sullenly the driver watched them go and then with a shrug of his shoulders, turned once more to his team. Gayly the two cars sped along the road, bearing four Outdoor Girls bent upon revenge. The going was rough and bumpy, far worse than the main road, but the girls never noticed it. "That was one time Grace had a good idea," Mollie was exulting as they flew along. "I never thought she was particularly brilliant before, but I have changed my mind." Then catching Mrs. Ford's eye, she added with a little laugh: "You see that's the way Grace and I talk about each other. Only," plaintively, "she says much worse things about me!"
