In the United States, ‘the average price per thousand re- 
ceived for common sand-lime brick was $6.36 in 1910, as com- 
pared with $6.39 in 1909, and $6.33 in 1908; for front brick 
$10.90 as against $11.98 in 1909, $12.16 in 1908, and $10.96 in 
1907.” In Manila the market value ought to be much greater, 
but, according to our estimate of the cost of producing front 
brick, even the above selling prices should leave a good margin 
of profit. 
SUMMARY. 
1. In the Philippines conditions are very favorable for the 
manufacture of brick and artificial stone from sand and lime 
if the enterprise is carefully and conservatively managed. The 
selection of a factory site, raw materials, process of manufacture, 
and machinery should receive unusual care. 
2. The best location for the first plant is probably in the vic- 
inity of Manila. Tests and information concerning the available 
raw materials indicate the advantages of locating a sand-lime 
brick plant near the Pasig River at Guadalupe. 
3. The cost of manufacturing and selling 20,000 9-inch bricks 
of the best quality is estimated not to exceed 13 pesos (6.50 
dollars United States currency) per thousand. Compared with 
other Philippine building materials of equal value this is very 
reasonable, and the profit of a plant could be increased by ex- 
tending its operations to include the manufacture of lime, hol- 
low building blocks, tiles, slabs, marbles, ornamental stones, etc.
