84 NATURAL HISTORY AND TOPOGRAPHY OF GROTON, MASS. 



1637 to 1788," leaf eleven. According to the indorsement, 

 the paper was written in the spring of 1684. The writer was 

 Dr. William Avery, a physician of Boston, who was concerned 

 in mining researches, as made in New England more than two 

 hundred years ago ; and his correspondent was Robert Boyle, 

 of London, who was much interested in the welfare of the 

 Indians. Eliot dedicated to Boyle the second edition of his 

 translation of the Bible. 



Cold Spring lies in the northerly part of Groton, near 

 Reedy Meadow, and is still known by that name. Marcasite, 

 mentioned in the paper, is a sulphide of iron resembling 

 pyrite or common iron pyrites in composition but differing 

 in form. For many years bog-ore has been found in that 

 neighborhood, and formerly was worked to a small extent. 



In the year 1684, the highest court in England declared 

 the charter of the Colony of Massachusetts Bay null and 

 void ; and the allusion in the last paragraph of the postscript 

 is to that anticipated event.
