﻿COMPOSTELA-DAXAO COAL FIELD. 403 



Danao. The saving in transportation and the greater regularity of the 

 beds might more than offset the cost of sinking a shaft and pumping. 



I may also add that drilling in the vicinity of the andesite formation 

 might, not improbably, discover anthracitized coal, should the andesite 

 come in contact with the coal bed at any point. This has been known 

 to be the case in the anthracite region of Colorado, in the United States. 



In conclusion it should be said that the coal formation in this district 

 does not differ greatly from that of Batan Island and operations in either 

 field will necessitate considerable outlay of capital. Furthermore, the 

 problem connected with coal mining in either field will tax the ingenuity 

 of any engineer and it will be a saving in the long run to spare nothing 

 in order to get the best man available.
