Rocks of ages

摘要

A MAN with a Stetson perched on his head reclines in his chair, an assortment of rocks displayed in front of him. A second man in a fedora browses the collection, pausing over one specimen. The size of a chocolate bar, the silvery rock is inlaid with a mosaic of grainy grey shapes. "What are you asking for that one?" asks the fedora. "Oh, somewhere around five thousand," replies the Stetson.
