The balloon went up. In silence they watched it rise to at last disappear in the clouds. At once the girl with wind-blown hair got busy with her instruments. “I’m feeling for the steel ball,” she explained. “I’ll have it presently.” “She’s feeling for the steel ball,” one of the buck private gunners repeated. “She’ll have it presently,” said the other. “Like h—l,” he muttered, under his breath.

Her first impulse was to say: “You go away!” She did not say it, but returned to her task. “Now,” she sighed once more, “I’ve got the steel ball’s location. I’ll set your gun.” This task she performed with speed and accuracy. The
