Ooops! You're right!  Ignore that previous posting!

Looking at faces of the waves in the figure labeled "Progression of the 
Wave," I see a downward component and a forward component, with the 
relative magnitudes changing as the face passes.  The water particles 
within the water have a _different_ motion than the _surface_ does.  I 
think I'm getting it, now.  The surface rises _not_ because bulk water is 
moving up, but rather, the disturbance is moving from left to right.

OK.  Apologies to Craig for doubting him, and thanks to Bob for clearing 
this up.  Mea culpa -- always glad to learn about a misconception.
