THE official report upon the mineral production of the Philippine Island's for the year 1915 has recently been issued by the Division of Mines Bureau of Science, of the Government of the Philippine Islands, o The importance of the gold production far outweighs that of. any other mineral; its value is returned as 2,633,528 pesos, say about 274,000l., being an increase of 12-1 per cent, above that of 1914. The gold bullion, of course, also carries a certain amount of silver, which is valued separately. The only other metallic product is iron, of which ninety-six tons appear to have been produced, this being only about one-half of the production of the previous year. This iron is all produced in small native furnaces, and is worked up into ploughshares or similar articles; the main reason in the falling off is the competition of inferior articles, made from scrap-iron. There is no production of native coal, none having been worked since 1912. The other minerals, of which returns are included, are salt, sand and gravel, clay products, stone, lime, and mineral waters. The total value of all these is estimated at rather less than the value of the gold output.
