Adam is sitting on the top branch and he can see the hats of Billy and Cyrus. Billy is sitting on a branch above Cyrus and he can see Cyrus hat. Duke is sitting at the base of the tree. Branches are covering him fully and no one can see his hat.

I am taken from a mine and shut up in a wooden case, from which I am never released, and yet I am used by almost every person. What am I?
