Answer:
Thirty white horses on a red hill, First they champ, Then they stamp, Then they stand still.
They have not flesh, nor feathers, nor scales, nor bone. Yet they have fingers and thumbs of their own.
As destructive as life, As healing as death; An institutioner of strife, Just as prone to bless. It is all that is good, Yet with an evil trend; As it was the beginning of things, It can also be the end.
I can be quick and then I'm deadly, I am a rock, shell and bone medley. If I was made into a man, I'd make people dream, I gather in my millions By ocean, sea and stream.
I fly, yet I have no wings. I cry, yet I have no eyes. Darkness follows me. Lower light I never see.
I have two eyes in the front and a lot of eyes on my tail
