For countless voyages I have hung over the bow of passenger

steamers in mid-ocean, making of myself a

figurehead of sorts, straining my eyes downwards to watch

the living creatures which whirled into sight and swept

past. Dolphins, flyingfish, tunny, an occasional shark

these are familiar to all who have ever glanced over the

bow. But the rays of the slanting sun striking obliquely

into the smooth surface often revealed a myriad, myriad

motes more like aquatic dust than individual organisms,

which filled the water from the very surface to as deep as

the eye could penetrate.
