THERE was no use in arguing with a person like this. I promptly put
such a strain on my memory that by and by even the shoal water and the
countless crossing-marks began to stay with me. But the result was just
the same. I never could more than get one knotty thing learned before
another presented itself. Now I had often seen pilots gazing at the
water and pretending to read it as if it were a book; but it was a book
that told me nothing. A time came at last, however, when Mr. Bixby
seemed to think me far enough advanced to bear a lesson on water-
reading. So he began -
'Do you see that long slanting line on the face of the water? Now,
that's a reef. Moreover, it's a bluff reef. There is a solid sand-bar
under it that is nearly as straight up and down as the side of a house.
There is plenty of water close up to it, but mighty little on top of it.
If you were to hit it you would knock the boat's brains out. Do you see
where the line fringes out at the upper end and begins to fade away?'
'Yes, sir.'
'Well, that is a low place; that is the head of the reef. You can climb
over there, and not hurt anything. Cross over, now, and follow along
close under the reef - easy water there - not much current.'
I followed the reef along till I approached the fringed end.
