The increased output of 10-7 per cent. in 1937 was accompanied by an increase of 250 per cent. in the total value of the coal produced in India from Rs. 6,24,98,404 (£4,699,128) in 1936, to Rs. 7,81,02,439 (£5,872,364) in 1937.

There was an increase of 5 annas 8 pies in the pit's mouth value per ton of coal for India as a whole, namely from Rs 2-12-3 to Rs. 3-1-11. Increase in value was recorded from all provinces with the exception of Assam, the Central Provinces, Eastern States Agency, Hyderabad and Rajputana (Table 10),

The development of an iron and steel industry in India on modern lines has led to the erection of several plants for the manufacture of hard coke of metallurgical quality and it has therefore become a matter of general interest to know the proportion of the total annual output of coal in India that is utilised in the manufacture of hard coke. The figures for 1936 and 1937 are shown in Table 14.

1936 and 1937.

In opposition to the trend of 1931, 1935 and 1936, the exports of coal from India in 1937 have more than doubled as compared with 1936, deducting Burma's share. Since the separation of Burma on the 1st April, 1937, it appears in these statistics as a foreign country, and in 9 months has taken a little more than Ceylon did in the year.
