An airplane had risen from the aviation field on their left and was flying at a leisurely rate in their direction. William leaned back on the sled to watch it as it flew over them and on toward Fort Jay. "I guess he's cold," he remarked. "That's what makes him go so slowly."

"Isn't the water pretty, William?" asked Lucy, looking toward the sea-wall, a hundred yards distant.

"Yes. He's coming back now," said William, still watching the aviator, who had circled about Fort Jay and was flying low over the parade at the edge of the new land, seeming to avoid the parade itself, where a few companies were marching out to drill.

Lucy turned from the water to follow the airplane's flight as it swooped down, barely a hundred feet above the earth, its white wings gleaming in the sunlight against the bright blue sky. Suddenly she stiffened. "Why, he's going to land, I do believe, and I think he'll come down on top of us!"

She seized the sled rope and pulled William and Happy off nearer to the sea-wall, while above them the airplane descended in a series of crooked dives to the ground. She could see the aviator pulling madly at his steering gear, as with a final glide the machine came to earth about two hundred yards from the sea-wall.

"Hoo-h!" breathed William, jumping up and down in his excitement.

The pilot stepped out with deliberation, and at sight of his slow walk Lucy recognized him, though his uniform was almost covered by a big sheepskin coat. It was the French aviator, Captain Jourdin, who, though discharged from active service for wounds, had taught since the declaration of war in the American Aviation Schools. He was a familiar figure on Governor's Island, where he spent a part of the time he divided among half a dozen places. His ankle was held in an iron brace, and he limped heavily in walking, but his general activity was not much impaired in spite of it. As he approached the children now, his keen dark eyes were fixed on them with a touch of anxiety.

"I beg a thousand pardons," were his first words as he neared the sled from which Lucy came forward to meet him. "I frightened you, I fear?" He looked from Lucy's face to William's for signs of alarm, while Lucy answered:

"Oh, no, you didn't—honestly. I got out of the way because I wasn't sure where you were coming down." She had never seen the famous young veteran so near before, and she scanned his face with eager interest.
