More questions on 19th C verse analysis

[Al Smitley]

As I have said before, I'm always most interested in verses, or often parodies of songs which refer to contemporary issues/events.  In "Zip Coon on the Go-Ahead Principle" there are a couple of verses in particular which I wonder if someone can shed light on.

--------

As I am writing this, on CSPAN3, an author of a book on integration began talking about the minstrel song, "Jim Crow"!!!!

--------

Ok back to the verses....... 

After a verse about Calhoun, Jackson, and the nullification issue is a verse that goes.

He try to run ole Hickory down, (3)

But he strike a snag and run aground

dis snag by gum war a wapper, (3)

and sent him into dock to get new copper

"new copper"? ....Any insights on this?  Funding, perhaps?

and then, the last verse goes.

Oh if I was president ob dese Nited States, (3)

I'd lick lasses candy and swing upon de gates,

An does I dina like why I strike em off de docket, (3)

De way I us'd em up was a sin to Davy Crocket.

What is the significance of licking molasses candy and swinging upon a gate?

And most of all, what are the last two lines saying?  I know that "sin to Davy Crockett" was a phrase used to denote a travesty, etc., but what does "An does I dina like why I strike em off de docket" and "de way I us'd em up" refer to?  and what was being "us'd up"?

[Silas Tackitt]

Copper to plate the hull, or in this case, replate the hull.

Candy and gates sounds like goofing off and generally having a good time at ease. 

Not sure about the rest of your questions. 

[Paul Certo]

Copper plates were used to protect the hull from hitch hiking water critters such as barnacles and certain wood-boring sea vermin.
