Chapter X
Minerals
“It is not only what towers above us, that makes our islands rich. Dig at your feet, and you will find valuable minerals! Magellan, the Spaniard, first discovered the Philippine Islands while he was on a search for gold, though I think a rubber tree, or a bamboo, is more valuable than gold,” said the wise Padre.
“We get gold in two ways,” explained Fil. “We wash it from scooped-up gravel, and we break it out of rock with a hammer.”
“And how do you melt your iron and copper?” I inquired.
“We dig coal, and use bamboo pipes and a bellows to make the draft. We put the ore into a clay kettle, and melt the rock out of it. Then, when the iron is pure, we heat it again until it is red, and beat it with hammers into shapes. Thus we make it into wheels, spears, axes, and so on,” explained Fil, who had watched the workmen at their labors.
“I know little about practical, mechanical affairs; tell me more,” urged Filippa.
“We have petroleum oil, just as America has; also, lead and paint ores. We have burnt-out volcano hills, composed of sulphur down into their deep hearts.”
“That is like a very bad place, way down below, that I have read about,” interrupted Moro; and Fil’s mother and the Padre shook their fingers at him for joking.
