In my email this past week was a missive from the news-editor of Mining.com.  He passed on a letter sent to him for possible publication.  I repeat the entire letter below.  It has the edge I like.  It has the honesty of an old man about to retire: I respect that.  It has the frustration of change; and we all know the feeling.  So here it is.  It was written by Jay Collins, P.
