assigned values to ores from Belgaum and Singhbliuin although, as far 
as I am aware, none of the ore extracted in these two districts had been 
exported up to the end of 1906. The amounts of ore extracted in 
these two districts is, however small, so that the values of these i'res 
do not make much difference in the totals. It is better to include the 
values of these ores under the years in which they were extracted, 
rather than when they were exported, so as to prevent confusion in 
the statistics. 
It will be seen from the tables that the total export value of the ore 
mined in the Vizagapatam district during the 15 years 1892 to 1906 is 
Rs. 1,24.19,012 or £827,934, giving an average annual value of 
Rs. 8,27.934 or £55,196 ; whilst th? total export value of the ore mined 
in the four districts of Balaghat, Bhandara, Chhindwara, and Nagpur. in 
the Central Provinces, during the 7 years 1900 to 1906, is Rs. 2,13,16,282 
or £1 ,421,086, giving an average annual value of Rs. 30.45,183 or £203,012. 
The total export value of the Indian Production during these 15 years is 
Rs. 3,65,61,913 or £2,437,462. It has risen from Rs. 15,755 or £1,050 
in 1892 to Rs.l ,45,36,131 or £969,078 in 1906, with an average aimual 
value for the whole 15 years of Rs. 24,37,462 or £162,497, and for the 
7 years 1900 to 1906 of Rs. 45.26,276 or £301,752.
