Deep Sea

Like liquid agate rest the bottoms of the sea,
Like caves pressed down by the unending hammerstroke
Of waves struck green with sun; and deepest creatures here
Are bubbles left in moving coils in agate, and dart
As ribbons cut in light, or fork electric eyes,
Waving them brightly tentacled, like drowning stars
Writhing in last extinctions of their glow.

In some such agate, slipping studded green, our thoughts
Are deepest, winnowing like strange fish the wheaty grains
Of light, self-lighted from the husks of dark.
