The stranger laughed with relief. Again his eyes smiled. “Oh,” he cried, “I see! Have I been trespassing?”

With a glance Jimmie measured the distance between himself and the stranger. Reassured, he lifted one leg after the other over the wall. “If you try to rush me,” he warned, “I’ll shoot you full of buckshot.”

The stranger took a hasty step backward.

“Don’t worry about that,” he exclaimed. “I’ll not rush you. Why am I arrested?”

Hugging the shotgun with his left arm, Jimmie stopped and lifted the binoculars. He gave them a swift glance, slung them over his shoulder, and again clutched his weapon. His expression was now stern and menacing.

“The name on them,” he accused, “is ‘Weiss, Berlin.’ Is that your name?” The stranger smiled, but corrected himself, and replied gravely, “That’s the name of the firm that makes them.”

Jimmie exclaimed in triumph. “Hah!” he cried, “made in Germany!”

The stranger shook his head.

“I don’t understand,” he said. “Where would a Weiss glass be made?” With polite insistence he repeated, “Would you mind telling me why I am arrested, and who you might happen to be?”

Jimmie did not answer. Again he stooped and picked up the map, and as he did so, for the first time the face of the stranger showed that he was annoyed. Jimmie was not at home with maps. They told him nothing. But the penciled notes on this one made easy reading. At his first glance he saw, “Correct range, 1,800 yards”; “this stream not fordable”; “slope of hill 15 degrees inaccessible for artillery.” “Wire entanglements here”; “forage for five squadrons.”
