A sample from Cebu gave the following analysis (by Cox) : 



Volatile combustible 36.44 



Fixed carbon 48.80 



Fixed carbon 54.58 



Ash 4.12 



Moisture 4.86 



Sulphur 1.88 



The production in 1909 was 31,000 metric tons. 



There is only one producing mine at present: The East Batan coal 

 company on the little Island of Batan. 



Petroleum. — Oil seeps have been noted at two places on the Island 

 of Cebu, two in Leyte, four on Tayabas Peninsula, and one in the Cota- 

 bato Valley in Mindanao. Three oil wells have been drilled, but no 

 appreciable flow has as yet been obtained. One well in Cebu reaches 

 a depth of 1,100 feet. The oil occurs in Tertiary sandstone and shales.

I. II. 



Specific gravity of filtered oil at 15.°5 C. 0.845 0.831 



Initial boiling point 80°C. 70°C. 



Percentage. 



First fraction, light oils 70° to 150 O. 27.0 36.5 



Second fraction, burning oil 150° to 300° C. 56.75 48.75 



Residium above 300° C. by differences 16.25 14.76 



Total 100.00 100.00 



Phosphate. — Small deposits of guano have been found in limestone 

 caves, but no rock phosphate. One small deposit of apatite crystals has 

 been found in Ilocos Norte. 



Sulphur. — Small deposits, scarcely large enough to be of commercial 

 value, occur in Leyte on the Island of Biliran, Mount Apo in Mindanao, 

 and a few other scattered localities. Ferguson found a fair deposit on 

 the Island of Camiguin in the Babuyanes group. 



Salt. — No large natural salt beds are yet known in the Philippines. 

 Some very salty springs occur in several provinces, principally in the 

 Mountain Province of Luzon. 



Asbestos. — Asbestos of the anthophyllite and baltimorite varieties 

 occurs in Ilocos Norte, but as yet only occasional veinlets of chrysolite 

 have been seen. There is no production and but little development work. 



Mineral waters. — The two principal springs are at Sibul, Bulacan, and 

 Los Bahos, Laguna. Two hundred and sixty-eight thousand four hun- 

 dred and forty liters were bottled and sold in 1908.
