The only way out of the yard that I now was in was to descend a few
stairs that led up into the centre (A) of an underground maze, through
the winding of which I must pass before I could take my leave by the door
(B). But I knew full well that in the great darkness of this dreadful
place I might well wander for hours and yet return to the place from
which I set out. How was I then to reach the door with certainty? With a
plan of the maze it is but a simple matter to trace out the route, but
how was the way to be found in the place itself in utter darkness?
