I began remembering ice-polished rocks that the glaciers once dropped along Maine valleys, when his quiet voice summoned me back to India and the convalescent camp beyond whose outer gate I stood. Two flags on lances formed the gate and the boundary line was mostly imaginary; but one did not trespass, because at about the point where vision no longer pierced the mist there stood a sentry, and the grounding of a butt on gravel and now and then a cough announced others beyond him again.
"I have permission," I said, "to find a certain Risaldar-major Ranjoor Singh, and to ask him questions."
He smiled. His eyes, betraying nothing but politeness, read the very depths of mine.
