(and barytes) in the deposit. Owing partly to this baryta the percen- 
tage of manganese — only 48 on the average — is lower than in the Cen- 
tral Provinces ; but this inferiority in manganese contents is to a certain 
extent neutralized by the fact that Meghnagar is only 361 miles from 
Bombay as against the .'520 to 701 miles distance of the deposits of the 
Central Provinces from Bombay and Calcutta respectively. Taking 
the average advantage in railway lead of Meghnagar over the Central 
Provinces as 240 miles, which is equivalent to a difference of railway 
freight of about 4s. 6d., we see that — taking the price of rnanganese-ore 
at 9d. per imit — this advantage in lead is roughly equivalent to a 
6% increase in the manganese contents of the ore. 
The sulphur and arsenic returned in the foregoing analyses are pro- 
bably due to the presence of barytes and arsenates respectively (see 
page 687). 
The local labour available is Bhil, but, as the Bhils are very uncertain 
^ ^ in their attendance and of too wild a disposition 
for continuous hard work, coolies have been imported 
from Ahmadabad. 
For variety of rare and new minerals this is the most interesting

Braimite. — Many fine crystals of braunite have been obtained from 
this deposit. An accoimt of them will be found in Part I, pp. 55 — 57. 
Hollandite. — The most interesting of these is hollandite, for an account 
of which see Part I, pp. 87 — 91. It occurs in the quartz veins that trav- 
erse the ore-body south of the waist of the hill and is especially abimd-
