and indicates the presence of about equal proportions of psilomelane 
and braunite in the ore. The agreement of this analysis with Mr. Winch's 
figures is noteworthy. 
North of the waist of the ore contains a larger portion of braunite 
and is often more coarsely crystalline, whilst there is abundance of 
spessartite and some rhodonite. According to Mr. Winch the average

I took two samples (A. 40 and A. 41) from the part of the deposit 
north of the waist. They represent 580 and 1,1.30 tons of stacked ore, 
quarried respectively from the southern and northern portions of this
