Answer:
Golden treasure I contain guarded by hundreds and thousands. Stored in a labyrinth where no man walks Yet men come often to seize my gold. By smoke I am overcome and robbed then left to build my treasure anew.
A hundred arms, a thousand fingers, but I have no eyes to see where I linger. What am I?
What can you catch but not throw?
I go through a door but never go in and never come out.
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. What am I?
Break me and I am better immediately set and harder to be broken again.
