Answer:
This patch of land stands alone
Barren location, infertile and dry; my name means "to leave", it's not heard to see why
What is something you will never see again?
How can a pants pocket be empty and still have something in it?
White and thin, red within, with a nail at the end. What is it?
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
