On one occasion I had gone down on duty to a certain stretch of trench and there found a puzzled-looking private with a beautiful new rifle fitted with an Evans telescopic sight.

“That is a nice sight,” said I.

“Yessir.”

I examined the elevating drum, and saw that it was set for one hundred yards. “Look here,” I said, “you have got the sight set for a hundred. The Hun trenches are four hundred yards away.”

The private looked puzzled.

“Have you ever shot with that rifle?” I asked.

“No, sir.”

“Do you understand it?”

“No, sir.”

“How did you get it?”
