Clean up? Here you go.

1. The time draws near, my dearest dear,
When you and I must part.
You little know the grace and awe
in my poor aching heart.
Each night I suffer for your sake,
for you I love so dear;
I wish that I could go with you,
Or you were staying here.

2. I wish my breast were made of glass
Wherein you might behold
that there your name appears, my dear,
In letters made of gold.
Oh there your name appears, my dear,
Believe me when I say
You are the one I love the best
Until my dying day.

3. The crow that is so black, my love,
will surely turn to white
If ever I prove false to you,
Bright day will turn to night.
Bright day will turn to night, my love
The elements will churn,
If ever I prove false to you,
The seas will rage and burn.

4. And when you're on a distant shore,
Think of your absent friend,
And when the wind blows high and clear,
A line to me, pray send.
And when the wind blows high and clear,
Pray send a note to me,
That I might know by your handwrite
How time has gone with thee.

Re: elements. Aristotle's earthly elements were air, water, earth and fire. I can picture them churning, say, at the eruption of Krakatoa, with its lava, ash in the air, tsunami and no doubt high winds. Another example would be the San Francisco quake and fire.

I decided to keep "handwrite." It's so nicely old-fashioned.
