The #mineral #howlite was discovered near #Windsor #NS in 1868 by #HenryHow, a prof at #KingsCollege. He was alerted to it by #miners at a quarry where it was a strange impurity in the #gypsum. Its main use is in jewelry, partly because it's porous and can be easily dyed.

The #mineral #mordenite is named for #Morden, #NovaScotia, where #HenryHow discovered it in 1864. It's used to clean up chemical spills, in animal feed and for water treatment.

#Morden was originally called #FrenchCross after a memorial to #Acadians who died fleeing the #British expulsion of the #French in 1755. A #driftwood cross stood there from 1756 to ~1820. Replacement crosses were built in 1887, 1924 and the current stone one in 1964.
