Answer:
What is seen in the middle of March and April that can’t be seen at the beginning or end of either month?
I count time, but have no end. Tick tick, but I am not a clock. What am I?
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.
A dragons tooth in a mortals hand, I kill, I maim, I divide the land.
Not a burden for its weight and daily carried out, He who takes it wishes it had never come about
All about, but cannot be seen, Can be captured, cannot be held, No throat, but can be heard. Who am I?
