As far as I can see, the rain

As far as I can see, the rain will come,
but not before I measure every cloud
and estimate the largest ones, while some
retreat from view.  The thunder starts, not loud.

As far as I can see, the dark will fall,
But not until I watch the sea, each wave
That rolls pretends to come ashore.  I call
Their bluff and see that motion's what they have.

As far as I can tell, the day will end
Quite soon, but not without the grassy marsh
Retrieving all the birds that daily fend
For food and nest and young.  Does life seem harsh?

The clouds, waves, birds, from what I see, survive
Past rain, dark, night, and so do I, to live.
