230 Mineralogy of Orange County, N. Y. 
lumbium.- The annexed diagram illustrates their figure, which is that 
of the Fer Oligiste imitatif of Haiiy. They have been found one 
inch in diameter, though their average size is considerably less. The 
Hornblende of this place is of a reddish brown color, often in very 
large and perfect six-sided prisms, with three and four sided termi- 
nations. 
Three quarters of a mile south-west of the above locality, in the mid- 
dle of a bye-path leading west from the main road, and distant about 
forty rods from it, (No. 1. on the map,) are found handsome beryl 
colored crystals of Apatite, associated with a purplish brown Augite, 
which is sometimes in distinct crystals of considerable size, but more 
frequently in granular concretions. In the same connection, also oc- 
curs, a snowy white Scapolite, not well crystallized, together with 
crystals of Plumbago. These minerals are imbedded in the Lime- 
stone, in a vein-like cavity which has been pursued down to the 
depth of a man’s head, and for a length of six or eight feet, and a 
breadth of about half this extent. The vein in which the minerals 
occur is said to have narrowed finally to about the width of two feet, 
and is probably near being exhausted. It is not improbable, howev- 
er, that similar nests will be discovered on examination ; for it is not 
rare to find in the Limestone, partial veins of the Scapolite in this 
vicinity. 
About half a mile north of the last mentioned deposit, No. 3, 0” 
the land of Daniel Layton, are a number of interesting substances. 
I did not visit the spot, nor am I informed of their mode of occur 
rence, but from the account furnished me by Dr. Young, I should im- 
agine, that they are found in loose masses distributed through the soil, 
in conformity with the usual circumstances under which the minerals 
of this region occur. These minerals are Spinel, in greyish red oc- 
tahedrons and hemitropes, from one to four inches in cireumferences 
whose crystals are often coated with steatite, and present various 
shades of green, yellow and black. Associated with them are tabu- 
lar crystals of Serpentine, destitute of lustre, and in a commencing 
state of decomposition ; also, Sphene and Augite,—these last re 
sembling specimens from Roger’s Rock on Lake George. i 
Locality No. 4, which is half a mile south-east of Amity meetins 
house, on the land of Moses Post, affords brown Spinel in large oct 
hedral crystals, but inferior in perfection to those of the Layton lo- 
cality. Dr. Heron possesses a single erystal from this place, weigh- 
ing fifty-nine pounds. A portion of one of its pyramids is detache
