ALABAMA MICA DEPOSITS 59 



At the tunnel level, the lower right entry extends 40 

 feet N., and the lower left entry, 60 feet S. Ten feet 

 higher vertically, the middle right entry has been driven 

 40 feet N., and the corresponding left entry 60 feet S., 

 connection between the first and second working levels 

 being by means of the three stopes shown on the plan. 

 The third or upper working level, located 10 feet higher 

 than the second or middle level, and about 6 feet below 

 the bottom of the vertical shaft, is opened up by means 

 of a 30 foot right or N. entry. The south workings on 

 this level are reached by three stopes from the second or 

 middle level, and have not been as yet run out N. to a 

 connection with the main E.-W. slope. On this left or 

 S. entry two working stopes, or rooms, have been driven 

 above it ten feet in length. 



The pegmatite deposit having been found to be narrow- 

 ing in the N. entries to finally about 3 feet or less, and 

 correspondingly widening in the S. entries to a final 

 width of 10 to 12 feet or more, the N. entries were tem- 

 porarily abandoned, and most recent recoveries made 

 altogether from the south side of the mine. All indica- 

 tions observable, both on the surface and in the mine, 

 point to a definite continuance of the pegmatite body S. 

 beyond the present mine limits, with favorable micaiza- 

 tion. From surface outcrops it is indicated also that its 

 extension N. may be possibly lenticular, and quite likely 

 to widen out in that direction beyond present mine limits, 

 or to prove of side displacement possibly overlapping. 

 The narrowing or pinching observed in the N. entries is 

 apparently caused by a rise in the foot wall. 



The prevailing characteristics of the pegmatite body 

 entered are a coarse aggregate, containing quartz intru- 

 sions in mass formation, walled uniformly top and bottom 

 by a reddish mica gneiss. An unusual condition observed 

 as compared with other mines in this immediate locality, 

 is the occurrence of the mica generally, and more espec- 

 ially the larger crystals recovered, imbedded in and on 

 the mica gneiss, along both the upper and the lower con- 

 tact, and in but few instances in or on the quartz. This 

 has been, according to the superintendent, Mr. John Ar- 

 nott, the quite uniform method of occurrence. The peg-
