So I strained at the cords which bound my elbows with all my might,
but I only hurt myself as the lashings drew tighter. I twisted from
side to side as I did this, and presently hit my elbow hard against
some metal fitting of the ship that seemed very sharp. Just at
first I did not heed this, but by and by, when I had fairly tired
myself with struggling, I minded it again, and so turned on my side
and set my free hand to work to find out what it was.

There was a stout post which came from beneath and through the
rough flooring of the cabin on which I lay, and went upward to the
deck. I daresay it was to make the cable fast to, but I could not
see that, nor did it matter to me what it might be for. But what I
had felt was a heavy angle iron that was bolted by one arm to the
post and by the other to a thick beam that crossed the ship from
side to side, so as to bind the two together. It had a sharp edge
on the part which crossed the floor, and it seemed to me as if it
had been set there on purpose, for if I could manage to reach it
rightly I might chafe through the cords at my back. Of course,
there was the chance of Evan coming in and seeing what I was at,
but I could keep my covering on me, maybe, and if Thorgils came, so
much the better. He would see that something was amiss.

It was no easy task to get myself in such wise that the cord was
fairly on the edge of the iron, but I did it at last, and,
moreover, I got the thick blanket that was over me to cover me
afresh. Then I started to try to chafe the cord through, and of
course I could only move a little at a time, and I could not be
sure that I was always rubbing it on the same place. And the great
