These figures show the manner in which the cost of manu- 
facture is influenced by local conditions such as the cost of fuel, 
labor, supplies, machinery, building, raw materials, quality of 
bricks produced, etc. They also show that the cost of produc- 
tion can be maintained at a comparatively low figure in spite of 
rather unfavorable conditions. 
In the Philippines, fuel for burning the limestone and for 
generating power is certain to be expensive even if local coal 
is used unless it is found practicable to locate the limekilns near 
a mine or an available source of firewood. Other items for 
which higher costs must be allowed, as compared with practises 
in the United States and Germany, are first cost of plant, ad- 
ministrative supervision, plant depreciation, repairs, supplies, 
and transportation by land. More definite information in this 
respect will be combined with an estimate of the cost of manu- 
facturing sand-lime brick at the suggested site on the Pasig 
River. This estimate is based on a plant having a capacity of 
20,000 bricks in twenty-four hours, and 10,000 pesos additional 
is allowed for extra machinery and molds for building blocks, 
tiles, ornamental products, etc. The cost of machinery and 
supplies is about 25 per cent more than the average price in the 
United States where ordinarily a well-equipped sand-lime brick 
plant with a daily capacity of 20,000 bricks costs, independent 
of site and building, about 40,000 pesos. To this sum of 60,000 
pesos, 10,000 pesos are added for a large factory site, and 10,000 
pesos for buildings: This brings the total cost of the plant 
to 80,000 pesos. Three estimates, including our own, of the 
amount of labor and raw materials required for 20,000 bricks 
are given in Table XX.
