Read it through once

I set out; I walked fast, but not far: ere I had measured a quarter of a mile, I heard the tramp of hoofs; a horseman came on, full gallop; a dog ran by his side. Away with evil presentiment! It was he: here he was, mounted on Mesrour, followed by Pilot. He saw me; for the moon had opened a blue field in the sky, and rode in it watery bright: he took his hat off, and waved it round his head. I now ran to meet him.
