254 Miscellaneous Localities of Minerals. 



3, Miscellaneous • 



The minerals in the immediate neighbourhood of Prince- 

 ton, are few, and possess but very little interest. Cubical 

 crystals of iron Pyrites are to be found along the margin o( 



Stony Brookjimbedded in shale. Crystallized quartz, is not 



uncommon. The crystals are generally imperfect, and not 

 very transparcnt- 



A bed of Argillite, very proper for buHding stone, cross- 

 es the road at the north end of the town — it makes a con- 

 siderable dip. In this bed, I have been informed that 

 wavcllite occurs, but I have in vain searched for it. 



Specimens of recen^/^ petrified wood are sometimes met 

 with lying on the surface. In my cabinet there is a piece, 

 which appears once to have been the lower end of a ches- 

 nut post, used for fencing — the exterior of it is black, a6 

 though it had been carbonized or charred. I have also 

 seen a mineralized chip^ with the marks of an axe very 

 apparent upon it — the petrifying matter is silex. 



Avery excellent bed of siliceous sand, used for mortar, 

 is near the road side, south east of the village. There are 

 other beds of sand in the vicinity. Silex in large pebbles is 

 not uncommon. Yellow earth is found on the side of a hill 

 in our neighbourhood — it is used for painting carriages 

 and is by artists considered as a very good substitute for the 

 tena de Sienna — with Prussian blue it forms a very delicate 

 olive yellow colour.
