326 Mineralogy of Orange County, JV. Y. 



crystallized, reddish hroivn Mica. This vicinity also affords the 

 Edenite in loose blocks, with whicli. Dr. Young has found large and 

 brilliant crystals of Rutile, possessed of numerous geniculations. 



Distant about forty rods from the last mentioned spot, upon the 

 land of B. Hopkins, is found the locality marked No. 11 upon the 

 map. It consists of a vein of Arsenical Iron, situated in the White 

 Limestone, but which here abounds with grey, massive Hornblende 

 and Augite. The vein has been explored to the depth of eight or 

 ten feet. The only mineral worthy of attention here is the Arse- 

 niate of Iron, or Cube Ore, which occurs upon one side of the 

 vein. This interesting substance forms druses of considerable size, 

 which, when examined with the microscope, present extremely mi- 

 nute facets, whose form cannot be detected with certainty in any 

 specimens I have seen. Its color is a dark green, with a tinge of 

 yellow and blue. It has formerly been regarded as Arseniate of 

 Copper. In connection with this vein, is found the Flos ferri variety 

 oi Arragonite, in seams of moderate extent. The branches or sta- 

 lactites are short, but possessed of a pure white color, and sometimes 

 handsome. Scapolite, Augite and Sphene, have also been found in 

 the immediate vicinity. 



The minerals next to be described, No. 5 on the map, are of a 

 still more interesting character. The spot where they occur is a 

 small field owned by William Raynor, situated about fifty rods north- 

 east of Amity meeting house. It is partly cultivated and partly cov- 

 ered by wood. On an elevated knoll upon the border of the wood, 

 and where the limestone comes into view in patches of limited ex- 

 tent, the diggings for minerals have been made. These are scatter- 

 ed over about a quarter of an acre of ground. The Limestone rocks 

 have been blasted only in one or two places at this spot ; the loose 

 stones and crystals found in the soil constituting the chief objects of 

 research. Bronzite, Spinel, Hornblende, Augite, and Plumbago are 

 the substances here found. The Bronzite has been described by 

 Mr. Finch in Vol. XVI, p. 185 of this Journal. It is now no more 

 obtained in large plates, by following the rock which originally afford- 

 ed it; but handsome folise, many inches across, are still procured loose 

 in the soil, or attached to masses of Hornblende. The Hornblende 

 is rarely found in regularly terminated prisms, but occurs in otherwise 

 very regular and well finished crystals, sometimes half an inch in di- 

 ameter, and one and a half in length. It is found both in loose crys- 

 tals, imbedded in Limestone, and contained in veins and cells in the
