Von Winden’s eyes met Hammersley’s and then he lowered his head upon the balsam boughs.

There was no time for amenities. Hammersley slipped on his leather jacket and cap, fastening his belt outside, reloaded his automatic, filled the pockets of Doris’s coat with biscuit and chocolate, then made a bundle of the tools and spare parts, which he selected carefully, and in a moment he and Doris were outside on the ridge, peering over toward the road below. All was quiet, and they descended carefully to the projecting rock, pausing there to listen again. The machine of Wentz, which had been left near the crag, had gone on toward Mittelwald. Hammersley smiled. The plan had worked. It was working. They must succeed.

Down in the bushes at the foot of the crag by the road they paused again, listening, and then Hammersley went forward, peering out, up and down the road. Silence. Solitude. Leading the way, with the hand of the girl in his, he quickly crossed and plunged into the undergrowth silently until they had reached a distance which would defy detection from the road. Then Hammersley bore to the right and went on rapidly.

Doris’s heart was beating high with excitement and hope. The Yellow Dove! Could they reach the hangar safely, and when there could they tune up undetected? The success of the venture seemed impossible for there must still be men on guard at Blaufelden—someone! But as they went on through the wood, she found some of the contagion of Cyril’s audacity. He seemed tireless. When they reached a trail which led in the desired direction, without speaking to her, he set forward into a steady jog trot which put them well upon their way. He turned around from time to time and watched her, and when he saw that she was nearly blown he slowed down to a walk and explained his plan.

“Jolly flyin’ weather this. Once we’re in the air they can’t stop us, Doris. She’s armored around the cockpit and engines, and they haven’t anything heavier than a rifle at Blaufelden. We’ll go up the Rhine to the sea, flyin’ high. Then cut to the left along the coast, as far as the French line, and then go in to Ypres and from there to General French’s headquarters. You can easily tell by the lines of trenches. I want you to listen carefully. I’ve got two seats and double control. The arrangement is just the same as on your Nieuport, only she answers her control much more slowly. The wheel is on a universal joint; the gas, on your wheel, the spark to your left, the magneto, a button in front of you. She starts by compressed air.”

“But the exhaust, Cyril,” she gasped, “before we go—it’s only a few hundred yards from the shed to the house!”

“We’re going to risk that. With luck we’ll be movin’ in three minutes, and then——” He paused grimly.

“And then——?”

“I’d like to see a dozen stop us.”

He had such perfect assurance that all doubt left her. Indeed, to Doris, he seemed endowed with some hidden fount of initiative and inspiration, and she was willing to believe anything he told her. They went on rapidly, while he answered all her questions and gave her final instructions, until at last they reached a path, the same, he told her, by which they had come from the farm last night. They started up a frightened deer, which fled away from them, but they didn’t pause until the path cut sharply to the right and through the bushes they could see the buildings of Blaufelden. There they stopped and Hammersley went forward to investigate.
