Geology of Deerfield, 8/-c. 115 



Laminated Calcareous Spar — in the same place, not uncom- 

 mon. 



Chalcedony, carnelian, iagate, amethyst, prehnite, zeolite, 

 chabasie, stilbite, and analcime, have been found nearly 

 in the same place ; and it may not be amiss to observe, 

 that this spot is distant from Deerfield Academy about 

 one mile, and bears from the same, by a true meridian, 

 E. 2", 16' S. 



Iron Sand — found in considerable quantity near the falls in 

 Connecticut river, on the Montague shore. 



Stdphate of Iron — in Conway, in small quantities, efflorescing 

 on mica slate. 



Sulphuret of Iron — in Halifax, Vermont, in abundance ; also 

 in Charlemont, Mass., Deerfield, &c. 



Magnetic Oxide of /ro«— *very common in the region west of 

 Connecticut river, I have observed it in Athol, Worces- 

 ter county. 



Specular Oxide of Iron — some veins of this ore occur in 

 Hawley, Bernardstown, and Warwick, and have been 

 wrought to a small extent. 



Micaceous Oxide of Iron — in the iron mine in Hawley. 



Green Carbonate of Copper — in greenstone, in Greenfield. 

 This ore constitutes a vein on the bank of Connecticut 

 river, passing into the hill on one side, and under the 

 river on the other. It has never been wrought, nor, 

 indeed, is its locality publicly known. 



Copper Pyrites — in the same vein, not abundant, at the sur- 

 face. 



Sulphate of Barytes — ^in the same place, constituting the 

 immediate walls of the vein. Its breadth on the wall 

 varies from an inch to a foot, and the breadth of the vein 

 is 6 or 8 feet. 



Galena — in Whately. This is probably from a continuation 

 of the vein of this ore that appears at Montgomer}-^, 

 Southampton, and Hatfield. A single crystal has been 

 found in the same range, in Greenfield, twelve miles 

 north of Whately ; but it wa« not in place.
