of the white carbonate of Hme, occur : Spinelle, colour reddish- 

 brown, green, and black, in octohedral crystals, associated with 

 orange-coloured Brucite. Brucite of various shades, from that 

 of a straw-colour, to dark-orange, and nearly black. Gray horn- 

 blende, in six-sided prisms, with dihedral summits. 



" In the Township of Hardiston. — At Sparta: Brucite of a beau- 

 tiful honey-colour: the finest we have is found here. Augite, in 

 six-sided prisms ; colour brownish-green. 



" At Sterling. — Spinelle, black, green, and gray, in octohedral 

 crystals. Brucite of various shades. Rutile; colour steel-gray ; 

 lustre metallic, in acicular prisms, with longitudinal stria?. Blende, 

 black and white ; the white sometimes in octohedral crystals, the 

 lustre brilliant. Dysluite, in octohedral crystals; colour brown 

 externally; internally yellowish-brown; lustre metallic (a new 

 mineral). Ferruginous silicate of manganese, in six-sided prisms, 

 colour pale-yellow ; associated with Franklinite. Tourmaline, im- 

 bedded in white felspar, in six-sided prisms ; longitudinally stria- 

 ted ; colour reddish-brown. Green and blue carbonate of copper. 

 A number of large excavations were made at the Sterling Mine 

 for copper, during the revolutionary war, under an erroneous 

 impression, that the red oxide of zinc was the red copper ore. It 

 was the property of Lord Sterling ; hence the name of the Sterling 

 Mine. Of copper, we only find there a trace of the green and 

 blue carbonate, 



" At Franklin. — Spinelle, black and red crystallized. Ceylonite, 

 green and bluish-green, in perfect octohedrons, truncated on the 

 angles ; lustre of the brilliance of polished steel. Garnets, black, 

 brown, yellow, red, and green, crystallized in dodecahedrons. 

 Silicate of manganese, light brownish-red. Ferro silicate of man- 

 ganese, of Professor Thompson, and the Fowlerite of Nuttall, light 

 red or pink, foliated and splendent; has much the appearance 

 of felspar; is also in rectangular prisms. Sesquisilicate of man- 

 ganese, lamellar in scales or small plates ; colour brownish-black. 

 Hornblende, crystallized. Actynolite, crystallized. Tremolite, 

 crystallized. Augite, common variety, crystallized. Jeffersonite, 

 common variety, crystallized. Plumbago, foliated and crystallized 

 in six-sided scales. Brucite of various shades. Scapolite, white, 

 crystallized. Wernerite, yellow, crystallized. Tourmaline, black,
