Thomas Williams Bicknell,
A History of Barrington, Rhode Island
(1898)
“ The boulders on our farms are the deposit of the ice, as are the sands and clay beneath the soil, and whether of slate, granite, quartz, iron, or whatever other formation, may be in many cases traced to the ledges in Massachusetts on the north. There is not a Barrington boy that has not seen the black, heavy ironstones of the field. There are some in town that will weigh fifty pounds. On Beacon Hill, Providence, where I now live, I have seen these stones that were two feet in diameter. On the island of Rhode Island, they are the size of cannon balls. ”
