definite data. Several analyses by Mr. C. B. White show 

 the quality of these ores to be: 



Iron. Phosphorus. 



Per Cent. Per Cent. 



"Smith" ore -.. 55-76 0.040 



" Daiicy" ore (surface sample) 63.49 0.176 



The next notable exposure occurs on the Black prop- 

 erty, on the north-eastern slope of Helton knob, on the 

 waters of Grassy creek, where several old "forge" banks 

 are located, whence the Paisley forge still draws its limited 

 supply. The old openings are now completely fallen in, 

 and nothing can be seen excepting the fact that there seem 

 to be two beds about 30 feet apart, the upper one of which 

 is reported to be 2 feet thick. The ore is soft and decom- 

 posed, in a friable, schistose gangue; and it is on account 

 of this softness that it was particularly prized by the 

 forges. 



Higher up on the same hill similar float-ore is repeat- 

 edly met with, scattered over the surface, and it seems to 

 cover a large area. 



About % mile slightly south of west from these old 

 " forge "-openings is a very prominent outcrop of horn- 

 blendic gneiss, at least 40 feet high, containing lenticular 

 masses of hard, compact magnetite, showing a thickness 

 of 3 feet at one point; and about 200 yards S. 60° W. 

 from here, on another ridge, some heavy and exceptionally 

 pure masses of float-ore were observed, indicating the exist- 

 ence of another parallel series of ore-beds. Unfortunately 

 none of the analyses of these ores were completed in time 

 for this paper. 



The "soft" ore, as used in the Paisley forge, is first 

 washed in an inclined wooden trough by a gently-flowing 

 stream of water; and an analysis by myself of this washed 

 product shows:
