Riches.

What mines the morning heavens unfold!
What far Alaskas of the skies!
That, veined with elemental gold,
Sierra on Sierra rise.
Heap up the gold of all the world,
The ore that makes men fools and slaves;
What is it to the gold, cloud-curled,
That rivers through the sunset's caves!
Search Earth for riches all who will,
The gold that soils, that turns to dust
Be mine the wealth no thief can steal,
The gold of God that can not rust.
