H. MINERALS OF GROUP I.

Antimony.

The production of antimonial lead obtained as a bye-product in the lead refinery at the Namtu smelter of the Burma Corporation Limited, decreased from 1,240 tons valued at Rs. 3,46,277 (L26,036) in 1936, to 1,150 tons, valued at Rs. 4,20,976 (£31,652) in 1937. This product contains 81.66 per cent. of lead, 17.69 per cent. of antimony, 0.21 per cent. of copper and 3.44 ozs. of silver to the ton, and is exported for further treatment.

An output of 183 tons of antimony-ore, valued at Rs. 18,240 (£1,371) was reported from the Amherst district, and 16 tons, valued at Rs. 1,056 (£79) from the Thaton district, Burma, in 1936. The output was 67.3 tons in 1937, but the value and district of origin have not been reported by the Burma Government.

Chromite.

There was an increase of 26 per cent. in the production of chromite in India, from 49,486 tons in 1936 to 62,307 tons in 1937. The total exports from India during the year were nearly 12,000 tons more than those of the previous year, and were about 12,000 tons less than the production, amounting to 50,367 tons, made up of 37,085 tons from British India and 13,282 tons from Mormugao in Portuguese India, as compared with 24,988 tons and 13,890 tons respectively in the previous year. The value per ton was Rs. 13.4, as against Rs. 12-2 for 1936.

Coal. In 1931, 1932 and 1933 there was a continuous decrease in production of coal from the peak figure of 23,803,048 tons in 1930. In 1934 the direction of change was reversed and production increased by 2,268,284 tons (or 11:4 per cent.) from 19,789,163 tons in 1933 to 22,057,447 tons in 1934. In 1935 the increase continued but at a less rate, by 959,248 tons (or 4:3 per cent.), to 23,016,695 tons. In 1936 there was again a decrease by 405,874 tons (1.8 per cent.) to 22,610,821 tons, followed, however, in 1937 by an increase of 2,425,565 tons (10-7 per cent.) to 25,036,386, the highest output yet recorded. This increase was shared by all provinces except Bengal and the Central Provinces, which showed slight decreases. All fields showed increased production, except Raniganj, Pench Valley and Giridih, and the unimportant fields of Rajmahal Hills, Raigarh State, Khasi and Jaintia Hills and Shahpur (Punjab).

As usual the output of the Tertiary fields was but a trival proportion of the whole, the proportions being 98.13 per cent. from the Gondwana coalfields and 1.87 per cent. from the Tertiary coalfields.

The variations in the statistical position of the coal industry since 1927 can be gauged to some extent by examining the stock position at the end of each year. Stocks increased continuously from 1929 to 1932. In the 1933 review it recorded that during 1933 the position showed no substantial change, but that the slight reduction of stocks might be symptomatic of a tendency towards better adjustment of production to demand. This surmise has proved to be partially correct, for during 1934 stocks were reduced by nearly 700,000 tons, increasing by 165,529 tons in 1935 and decreasing by 207,524 tons in 1936 and by 83,609 tons in 1937.
