LECTURE TITLEThe Bristol Copper Mine, Bristol, Connecticut." 

In 1798 Theophilus Botsford investigated a stream in Bristol, Connecticut with greenish water that was killing plants.  He ran a plow over the ground and opened a vein of "variegated" copper ore (chalcocite).  The land was owned by Sarah Yale, a name you'll hear again in this talk.

From 1835 until 1859 the deposit was worked by groups for copper ore and proved to be the most important source of copper in the Northeast. 

Copper from here helped establish the important brass industry and the famous clock industries of Connecticut as well as the sterling silver industry. 

Many noted individuals were involved in the mine - Abel Yale, Charles Wheatley, Benjamin Silliman, and two other Yale professors Whitney and Woolsey.  Eliphalet Nott, Union College, was involved as was Captain Williams who sank the Mine's first shaft.  

The Bristol Copper Mine holds a couple of firsts - the first mine strike in the U.S., the first Catholic church service in the U.S. in the 1840s - remember the southwest was in Mexico then. 

Chalcocite from here is world famous and rivals specimens from Cornwall, England. Bateman of Yale also proved Bristol chalocite was a primary mineral not secondary as had been believed. 

Refreshments served.
