326 Mineralogy of Orange County, N. Y. 
crystallized, reddish brown Mica. This vicinity also affords the 
Edenite in loose blocks, with which, 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 
of Arragonite, in seams of moderate extent. The branches or st- 
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 porth- 
east of Amity meeting house. It is partly cultivated and partly cov- 
ered by wood. On an elevated knoll upon the border of the woot, 
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- 
edit; but handsome folie, 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 ee 
very regular and well finished crystals, sometimes half an inch in e- 
ameter, and one and a half in length. It is found both in loose cry* 
tals, imbedded in Limestone, and contained in veins and cells 0 the
