O She look'd out of the window as white as any milk;
And He look'd in at the window as black as any silk.


Chorus:
Hulloa, hulloa, holloa, hulloa, you coal black smith!
You have done me no harm
You never shall change my maidenhead that I have kept so long;
I'd rather die a maid, Yes, but then she said,
And be buried all in my grave
Than to have such a husky, dusky, musty, fusky coal-blank smith
A maiden I will die.

Then she became a duck
A duck all on the steam;
And he became a water dog
And fetched her back again.

Then she became a fly,
A fly all in the air;
And he became a spider
And fetch'd her to his lair

Then she became a silken plaid,
And stretchd upon a bed,
And he became a green covering,
And gaind her maidenhead.
