high point on the north. At the southern end is the old O'Neill 

 shaft, now used for pumping and in the fall of 1907 tapped by the 

 northern workings. 



Two hundred feet or so north of Cook shaft, is the Thompson, 

 long abandoned, and beyond this an interval of some distance with 

 no workings. Recently diamond drilling has, however, revealed 

 ore, which may in time be worked. The hill then abruptly drops 

 away to a small valley, on whose northern side are two old mines, 

 the Hall and the Sherman, which were early discovered but which 

 have long been idle. The property has passed to Witherbee, 

 Sherman & Co., and has lately been drilled. Ore has been found 

 in rocks the same as at Mineville, and constitutes a reserve for 

 the future. 



It is natural to consider these last mentioned beds the northern 

 extension of the Smith mine, and it as representing the Old Bed 

 group, farther east and lower down than the Barton hill-Fisher 

 hill-Burt lot series; but inasmuch as the O'Neill shaft is over a 

 mile from the last exposure of the Old Bed series with almost no 

 outcrops between, and in rocks that are practically massive, one 

 may quite as well regard the northern ones as totally distinct ore 

 bodies. Again one's train of thought is necessarily influenced by 

 the sedimentary or igneous views of origin. The axial trend of 

 the Smith mine is parallel to the same feature in all the others 

 to the south, and therefore shows the same great structural char- 

 acter, presumably due to folding whose compressive strain being 

 at right angles to these axes, operated in a northwest, southeast 

 direction. 



Farther on to the north, no ore is known for 2 or 3 miles, and 

 then the beds are comparatively thin and have been long abandoned.
