85° southeast. Directly over the inclined shaft, or slope, an old 
drift was driven into rock for about 65 feet, but no ore is visible 
in it. The walls as seen at the surface and in the old cut are 
Pochuck-Grenville, but so heavily intruded with pegmatite as to 
consist in part of pegmatite itself in places. The pegmatite is both 
dioritic, where seen in the hanging wall of the open cut, and syenitic, 
where it occurs in the footwall. Both pegmatites are facies of the 
Pochuck and are intimately related to the ore. At the bottom of the 
mine the footwall in direct contact with the ore is typical Pochuck- 
Grenville. 
The ore is coarsely crystalline, with considerable admixed rock, 
and probably occurs in bands and streaks interlaminated with the 
country rock. The magnetite occurs in end-stage relations replacing 
Pochuck-Grenville, and carrying a little pyrite. Work was aban- 
doned some time after the summer of 1919, and has not since been 
resumed. ‘The slope is now full of water (see plate 2, figure 1 and 
plate 10, figure 1). 
The Wetherby and “Rattlesnake’’ mines. These are old 
openings south of the Forest of Dean mine. The Wetherby lies on 
the west slope of the hill facing Deep Hollow, about 11% miles south 
of the Forest of Dean mine, and at an elevation of 900 or \1000 feet. 
The structure here strikes north 40° east and dips from 80° to 85° 
southeast. An old shaft, of unknown depth and water-filled, exposed 
about 4 feet of streaky, irregular, mixed magnetite and rock. The 
footwall is Pochuck-Grenville, the hanging wall syenite-soaked and 
heavily granitized Pochuck-Grenville. A narrow crush-zone, not 
over a foot wide, runs through the property, which would indicate 
some probable displacement. There are no available data as to the 
character or extent of the ore. The “ Rattlesnake” mine is situated 
only a few hundred feet southeast of the mine pond. There is an 
old shaft, of unknown depth, and a cut through drift, now more or 
less filled by caving, on the property. 
No ore was visible and no information could be secured as to the 
extent of the workings or the quality and character of the ore.

The Bull mine. A little over a mile north of Oxford and 3 miles 
north of Monroe in one of the detached hills of gneiss referred to in 
earlier pages of this bulletin as “stranded fault blocks” (see 
page 32), and locally known as Bull hill, an old opening called 
the Bull mine is located. The cuts and shafts are on the top of
