varies from 9.50 pesos to 10.50 pesos per metric ton. Good coal 
for generating power and burning limestone can be obtained, but 
a careful selection is necessary as shown by the analyses given in

€ Miike coal has the highest calorific value, but its easily fusible ash and high content of 
sulphur are detrimental to its efficiency. 
The cost of manufacturing sand-lime brick would be exces- 
sive if the manufacturer paid the prevailing Manila market 
prices for lime. One merchant quoted 30 pesos per ton for 
quicklime which is considerably more than the cost of Portland 
cement. Another submitted figures on poor material of local 
manufacture which were equivalent to air-slaked rock lime at 
17.08 pesos per ton. This high market value is largely due to 
the crude process of local manufacture and to the small and
