Pearl:

[heslopian]

I saw the prancing horses die at waters edge. "Water's"
With manes that tossed , they made me cry at water's edge.

And left my crystal tears, a sob to soak the sand. Should that be "me" instead of "my"?
To flood the ocean by and by, at water's edge. This sentence seems to be a conjunction of the first, so I think a comma should go after "sand".

The wind; I loved the salty spray it lifted high. I think a colon would be more appropriate there than a semi colon.
I closed my eyes, became the sky at water's edge.

When sulky clouds, through bellows, blow among the waves. "Blow" should be "blew".
The tremor from the sea, a sigh at water's edge.

Arizona! Rest at peace below the thoughts of men.
Of battleships beneath, that fly the water's edge.

You need to edit the syntax a bit, but otherwise this is a very good poem. Pretty, picturesque, and with certain hidden depths, meanings.
