the ridges and lie scattered along their sides, but the greater portion of ore 

 deposits in this region exist in the form of broken pieces of small sizes and 

 coarse ferruginous gravel. From its generally broken condition it is difficult 

 to estimate the thickness of the ore deposits in this region, but it is probable 

 that about three feet of good workable ore- will be found throughout the 

 greater portion of the ridges. On Pilot Hill the ore when seen in place has 

 this thickness. 



While the quantity of ore found in the region forming this field may not 

 show a thickness of more than three feet, and a great extent of the area may 

 not exceed two and one-half feet, the sides of the hills all show a large quan- 

 tity of debris from which vast quantities of workable ore may be readily and 

 cheaply obtained. The enormous erosion which this region has undergone 

 has been the means of removing the soft underlying yellow colored sands and 

 allowed the ore blocks and fragments to fall down along the sides of the hills 

 and ridges, until now these accumulated blocks form deposits of ore many 

 feet in thickness, and which will require years of steady mining to remove be- 

 fore the ore beds now in place will require to be touched. It may be esti- 

 mated that within this ore field each square mile of ore deposits carries in the 

 neighborhood of seven million tons of ore. 



Specimens of ore collected in this field give the following analyses:

The central or Brownsboro ore field consists of a number of flat-topped 

 ridges, extending in a generally north and south direction, and covers an 

 area of nearly two square miles. This field appears to be a continuation of
