There were drawings, too—sketches of cannon, of rifles, of swords; drawings of soldiers in various gay uniforms, all carefully coloured by hand. There were pictures of ships, from the sterns of which the crescent flag floated lazily; sketches of great, ugly-looking objects which her father explained were Turkish ironclads. The name “ironclad” always sounded menacing and formidable to the child, and the forbidding pictures fascinated her.

“Plans,” her father explained vaguely. And, when pressed by reiterated questions: “Plans for military works, I believe—forts, docks, barracks, fortified cuts and bridges. You are not yet quite old enough to understand, Ruhannah.”

“A German friend of mine, Herr Conrad Wilner.”

“What for?”

“I think his master sent him to Turkey to make those pictures.”

“For the Sultan?”

“No; for his Emperor.”

“Why?”
