This is partly inferred from the circumstance of its having been noticed that the Igorots, who occasionally come down from the mountains to barter with the Christians, use certain coarse jars or vessels of copper, evidently made by themselves with the use of a hammer, without any art or regularity; and as the ignorance of these demi-savages is too great for them to possess the notions necessary for the separation of the component parts which enter into the combination of minerals, and much less for the construction of furnaces suitable to the smelting and formation of the moulds, it is concluded they must have found some vein of copper entirely pure, which, without the necessity of any other preparation, they have been able to flatten with the hammer and rendered maleable, so as to convert it into the rough vessels above spoken of.
There are no mechanics deserving the name in Rome; who, by the way, are the very people Antonelli said he meant to benefit. But, apart from the want of mechanical skill, there is the dearth of the raw material; for maleable iron was selling in Rome at upwards of £21 per ton, at a time when the cost of bar-iron in this country was only from £6 to £7 per ton.
