A metal neither black nor red,
as heavy as man's golden greed.
What you do to stay ahead,
with friend or foe or arrow and steed.
Only one color, but not one size.
Stuck at the bottom, yet easily flies.
Present in sun, but not in rain.
Doing no harm, and feeling no pain.
I view the world in little space,
Am always changing place;
No food I eat, but, by my power,
Procure what millions do devour.
