Old World Power Tech.. The Groton School. 

It looks like there should be statues up in those alcoves ... also , does teched up equals melted ? I just wondered

In 1900, Groton supposedly had 2,000 residents. They were very impressive wagonaires and tradesmen, women, and children.

Those gray blocks, and i know it sounds unbelievable, they are blocked up and petrified red bricks. I have found ample evidence of that being the case in our country. Check all blocks very carefully and you may found some evidence of this proces.
