The above analysis indicates that the braunite and psilomelane are 
present in about equal proportions, and shows that the talus-ore is of 
fairly good quaUty. 
A section seen in one of these talus-ore pits was as follows : — 
2 feet soil, 
2 to 3 feet pebble-ore, 
3 feet fine gravel of manganese-ore pisolites, 
1 foot 4- decomposed coarse muscovite-quartz-felspar-rock ( ? pegmatite or 
gneiss). 
The trench shown on the plan was 12 feet wide and 6 o 10 feet deep 
and showed a few feet of gravel of manganese-ore and quartz of the size 
of peas resting on talus-ore and this on rock in siiu. The latter was 
composed largely of fine-graine ; buff-coloured gondite with bands, 
lenticles, and patches, of quartz. This rock was often changed to man- 
ganese-ore in patches, or along a network of fine lines. The rock also 
contained a fibrous chocolate-brown mineral — apparently a pale- 
yellowish amphibole (?) impregnated along cracks with oxides of man- 
ganese and iron. In the excavation B the same rock was exposed, the 
spessartite-garnets being in places as large as J inch in diameter. 
Neither the strike nor the dip of the rocks was seen, but, judging 
from other deposits along this belt, the strike should approximate to 
east and west, with the dip to the south side. 
This deposit was abandoned owing to the small quantity of ore ob- 
tained from it : but, in 1907, 537J- tons of ore were
