outcrop under the drift of the Harmony bed, 400 or 500 feet away, 

 is 450 feet higher. If the latter is the prolongation of the former 

 there is a very great fault in the interval. On the other hand, if 

 we attribute to the Barton hill group a swerve to the eastward 

 under the cap of drift, there is a very strong probability of con- 

 necting up with the Harmony bed. There is unexplored ground 

 in between with evidence of some disturbance. The composition 

 of the Harmony ore as regards phosphorus is intermediate between 

 the Barton hill and the Joker. It is higher than the former and 

 lower than the latter. The percentage in iron is somewhat less 

 than the Joker. 



A third possibility must be considered, namely, that it is a 

 totally distinct bed having no necessary connection with either of 

 the older ones. While it is natural to seek to connect together 

 those already known, it must be admitted that the last view can 

 not be entirely ruled out. 



Barton hill mines. These openings are distributed along a 

 practically continuous bed whose outcrop is approximately 3500 

 feet long in a direction a little east of north. From the 1300 con- 

 tour on the south, the outcrop rises to the 1750 on the north. From 

 the southern end of the outcrop the underground workings follow 

 an extended shoot of ore some 2000 feet farther on a flat dip to the 

 southwest; and along its axis this particular branching pod must 

 be fully half a mile long. 



Taking the Barton hill bed as a whole it is characterized by 

 swells and pinches giving the enriched and thickened shoots which 

 have been specially followed in the mines. Their axes and there- 

 fore the workings run northeast and southwest and are therefore 

 closely parallel with the Old Bed group, and with the Harmony 

 beds. No doubt the relationship is due to the general system of 

 folding which prevails in the gneissoid rocks and which has caused 

 the rolls and attendant bulging. Upon the map of the Mineville 

 area [fig. 6] the successive openings are given. They begin on the 

 south with the New Bed, which is the deepest and most extensive. 

 Then follow the North pit and the Arch pit, of moderate extent. 

 From the Arch pit a tunnel is now being driven northwest on a 

 slightly ascending grade so as to bring out by a gravity tram, the 

 ore which may be tapped in the downward extension of the more 

 northerly shoots. Already some gratifying discoveries have been 

 made. 



The next pit on the north is the Lovers Hole, the famous opening 

 from which came the extremely rich ore and the remarkable crys-
