THE MINERALS: GOLD
into Philippine coal unless they know more about it than I do.
It has often been said that the Philippines have never been explored. This is, however, only true of certain regions, and as regards beds of the so-called coal you will find them marked on the maps all over the principal islands.
If you proceed to the village nearest the spot, you will find, very probably, that the seam has been known for a century, and that pits or adits have been made and a lot of money spent to no purpose. Nobody ever made any money out of Philippine lignite that I know of, but I don't prophesy whether anybody ever will.
I append an analysis of some so-called coal that was brought me from Masbate in 1889.
