Geology of Deerfield, §c. 11¢ 
Laminated Calcareous Spar—in the same place, not uncom- 
mon. 
Chalcedony, carnelian, ~agate, 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, 
KE. 2°, 15’ S. 
Jron Sand—found in considerable quantity near the falls in 
Connecticut river, on the Montague shore. 
Sulphate of Iron—in Conway, in small quantities, eflorescing 
on mica slate. 
Sulphuret of Iron—in Halifax, Vermont, in abundance ; also 
in Charlemont, Mass., Deerfield, &c. 
Magnetic Oxide of Iron—very common in the region west of 
Connecticut river. 1 have observed it in Athol, Worces- 
ter county. 
Specular Oxide of Tron—some veins of this ore occur im 
Hawley, Bernardstown, and Warwick, and have been 
Wrought to a small extent. 
Micaceous Oxide of Jron—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. 
opper 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 fvot, and the breadth of the vein 
_ is six or eight feet. : 
Galena—in Whately. This is probably from a continuation 
of the vein of this ore that appears at Montgomery, South- 
ampton, and Hatfield. A single crystal has been found 
in the same range, in Greenfield, twelve miles north of 
Whately ; but it was not in place.
