PRESSURE AND THE PRECIOUS
Green plants producing food to feed
Of value to man’s daily need
And when the fruitful harvest’s o’er
The plants descend toward a value more.
Vegetation pressed down, decayed
Heavy pressure thereon laid
Becomes useful coal, a mighty force
Cooks the food from garden grown
And warms the family in the home
For jobs and goods a grand resource.
More pressure piled on black coal fuel
Produces diamonds’ crystal jewel
The hardest substance in the world.
In all the simple element
Is carbon rearranged:
We need not be of special stuff—
Just under pressure changed.
