The following section shows all particulars with regard to 

 the boring: 



It will be noticed how the rate of boring decreased when the 

 drills left the soft shales, and entered the hard blue slate, and 

 although not shown in the section, bands of quartzite were also 

 met with. As seen by the record the cores would seem to show 

 that the vein had feathered out into the shales or that the angle 

 of dip was much more nearly vertical than at first assumed. In 

 support of this latter theory it must be stated that the cores
