of the outcrop the dip varies from 25" ro 70° to the north side, about 
the middle the rocks become vertical, and in the eastern half they dip 
at about 50° to the S, 30° W. The greatest width of outcrop seen was 
14 yards, at a point a little to the west of the middle, the dip being 60° 
to N. 40° E. This corresponds to an actual thickness of 36 feet. The 
' country ' was not properly exposed, but probably consists of mica- 
schist and white vitreous quartzites. At the point where the ore-band 
is vertical there is seen in actual contact with the ore a rock composed 
of vitreous white quartz and flattened plates, up to ^ inch across, of 
slightly magnetic hematite, which gives a decided reaction for man- 
ganese and hence is perhaps to be regarded as manganiferous hematite. 
Where the forest lane, dividing the mdlguzdri land from reserved 
forest, crosses the ridge, a second ore-band is indicated at a distance 
of 70 to 80 paces to the south of the main band. It consists here of 
good-quality ore and is possibly to be traced along the south slopes of 
the ore -ridge. 
The main ore-band consists nearly entirely of good-quality ore in 
Constitution of the parts to the west of the forest lane, there being 
on-band. a little spessartite and quart'zite in places. Where 
the lane crosses, these latter become much more abundant, and to the 
east of the lane there is not a large quantity of good-quality ore exposed, 
spessartite and quartzite being much more abundant. 
The ores consist mostly of the hard grey fine-grained braunite-psilo- 
Nature nr.d quality melane mixture, often containing a little of the 
of the ores. bronze manganese-mica {'!) This ore tends in places 
to pass into coarsely crystalline braunite, and one piece was found of 
the friable type, consisting very largely of small grains of braunite with 
but a small proportion of the psilomelane cement. Another specimen 
contains a band of the very magnetic manganese-ore (vredenburgite) 
found at Beldongri (see page 609). A sample was taken from the out- 
crop in mdlguzdri land and consisted of all the varieties of ore, but chiefly 
of the first-named. It was analysed at the Imperial Institute with the 
following result :— 
Sample No. 57. 
Manganese peroxide 
Manganese protoxide 
Ferric oxide . 
Sihca (combined)
