How about a spelling test this week… a rockhound spelling test?  This spelling test appeared in the November 1962 edition of “The Earth Science News”.  It’s attributed to the “PICK and DOP STICK”, which is the monthly bulletin of the Chicago Rocks and Minerals Society, which has been organized as a club since 1946.  That’s 3 years before ESCONI’s start!  They are still going strong.  You can find out more about their club on their website.  So, have a try at the test… the answers will be posted in a few days.
