In places they contain quartz lenticles, sometimes of large size (one was 28 
paces long, by 19 broad in the middle). These phylUtes usually have a 
steep dip towards the western side of the ridgel and rest upon the rocks 
constituting the ore-body, these in their turn being superposed upon a 
great thickness (probably at least 400 feet) of schistose sericitic conglo- 
meratic grits, the base of which is hidden by the alluvium of the plain 
to the east of the ridge. The ore-body consists of beds of manganese- 
1 At the southern end of the ridge the dips vary from vertical to very steep to either 
side of the strike.
