Note 82 — PART I
Reading edition
Of iron they have whole mountains in the very vicinity of Manila! (provinces of Pampanga and Bulacan), some of the ores yielding 75 per cent. of metal, and of an excellent quality, this having been ascertained by some Biscayan iron-masters sent out for that purpose. It contains great numbers of magnets. There are some miserable establishments for working and smelting these ores, but on a very small scale; they have only produced cast iron articles, and those of an inferior quality. They have no forging machinery.82
