52.--_Crossing the Moat._

I was now face to face with the castle moat, which was, indeed, very wide

and very deep. Alas! I could not swim, and my chance of escape seemed of

that the oars had been taken away, and that there was nothing that I

could use to row me across. When I had untied the rope and pushed off

upon the water the boat lay quite still, there being no stream or current

to help me. How, then, did I yet take the boat across the moat?
