Laminated Calcareous Spar—in the same place, not uncommon.
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, E. 2°, 15′ S.
Iron Sand—found in considerable quantity near the falls in Connecticut river, on the Montague shore.
Sulphate 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 Iron—very common in the region west of Connecticut river. I have observed it in Athol, Worcester 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 surface.
