 the bed rock at or nearly in place, and the subsequent crushing of the 

 fine intersecting stringers of calcite and quartz.

 a native miner assisted by his wife and two male helpers, washed ap- 

 proximately 7.5 cubic meters of gravel, cleaning up therefrom 260 grams 

 of gold for which they were paid 15.60 pesos,-" equivalent to about 2.08 

 pesos per cubic meter. This was considered as an average run and will 

 give an idea of the richness of the gravel and what might be accom- 

 plished if mining were undertaken on a large scale and with such modem 

 hydraulic methods as are practiced in California. 



The smaller tributary creeks contain no water except during the rainy 

 season, but the larger creeks such as the Cansuran, the Bigaa and the 

 TagTinaan (or Caningan) are fairly large water courses and probably 

 never run absolutely dry. The last two, by the way, showed about as 

 good results in panning as did the first, yet very little mining is done 

 at present on any except Cansuran Creek.
