Sandstone with embedded Agate

Tom's handout, Geofacts No. 11, also discusses Sandstone and Conglomerate.  I had always thought of sandstone as the equivalent of sand.  Somewhere it is said not to build your house on sand.  I was surprised to observe that some buildings I once owed were built on a sandstone foundation.  The buildings were near the end of their serviceable life when I owned them.  The foundation was disintegrating inside and out.  There was still ample mass remaining to comfortably support the weight of the building.  I learned from the handout that sandstone was being used the 1800's for foundations.  It is also used for many things used in our daily lives.  Check it out!
