Answer:
What can you share and still have all for yourself?
Without a bridle, or a saddle, across a thing I ride a-straddle. And those I ride, by help of me, though almost blind, are made to see.
I dig out tiny caves and store gold and silver in them. I also build bridges of silver and make crowns of gold. They are the smallest you could imagine. Sooner or later everybody needs my help. Yet many people are afraid to let me help them.
I have three hundred cattle, with a single nose cord
I always run but never walk, I sometimes sing but cannot talk, No head on which a hat to place, You always look me in the face.
