230 Mineralogy of Orange County, JY. Y. 



lumbium. The annexed diagram illustrates their figure, which is that 

 of the Fer Oligiste imiiatif 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 w^ell 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 fi:nally 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, on 

 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 circumference, 

 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. 



Locality No. 4, which is half a mile south-east of Amity meeting 

 house, on the land of Moses Post, affords brown Spinel in large octa- 

 hedral crystals, but inferior in perfection to those of the Layton lo- 

 cality. Dr. Heron possesses a single crystal from this place, weigh- 

 ing fifty-nine pounds. A portion of one of its pyramids is detached
