About three miles West of the tavern in Haddam, in a 
cross road, Dr. Webster says, “I discovered in a vein four 
inches wide and four feet long, in a decomposed mica slate, 
and in the sand proceding from its decomposition, the 
finest crystalized spidiats, which I have seen — an

court-yard of a dwelling house, and passes under the house, 
into its cellar. Mineralogists have found it necessary, and
