Read it through once

Moving the lamp as the man moved, I made out that he was substantially dressed, but roughly, like a voyager by sea. That he had long iron-grey hair. That his age was about sixty. That he was a muscular man, strong on his legs, and that he was browned and hardened by exposure to weather. As he ascended the last stair or two, and the light of my lamp included us both, I saw, with a stupid kind of amazement, that he was holding out both his hands to me.
