SAND-LIME BRICK. 345 
and operating necessities, and put the finished product in close 
communication with the railroads, and, by short water route, 
with the ships in the harbor, while close at hand would be the 
volcanic tuff, and the sands from Pasig, Mariquina, Pasay, and ° 
Manila Bay. 
The advantages of Manila as a location are all those which 
accrue from proximity to the main port and largest city of the 
Philippines. The disadvantages are: (1) the transportation of 
the limestone over a distance of 7 kilometers by land and 17 by 
water; (2) the lack of natural protection at Binangonan where 
an anchorage must be provided for floating stock against severe 
storms which occasionally sweep Laguna de Bay; and in all 
probability, (3) the impossibility of using the best sand (Tarlac 
sand) on account of prohibitive freight rates. 
OTHER PLANT SITES. 
Although at present Manila appears to be the most suitable 
place for a sand-lime brick plant, other localities should be given 
thorough consideration. It is possible that the Visayan Islands 
and Mindanao will develop more rapidly than the rest of the 
Philippines, and the growing importance of Cebu, Iloilo, Zam- 
boanga, and Jolo as ports may eventually make a central location 
more desirable than Manila. j 
Cebu.—ASs yet we have made very few sand-lime bricks from 
raw material other than those already reported. However, some 
of the important considerations involved have been thoroughly 
covered by Wallace E. Pratt, of this Bureau, in a recent report?® 
on the available raw materials and locations for the Portland 
cement industry. This and other available information indicate 
that the vicinity of Cebu, Cebu, the second city in size and 
importance in the Archipelago, would be a suitable central loca- 
tion for the industry. Large deposits of subbituminous coal 
occur on the Island of Cebu near the seaport towns of Danao 
and Naga. Danao is situated 38 kilometers north and Naga 
19 kilometers south of Cebu City with which they have rail- 
way as well as water connection. Mr. Dalburg of this Bureau 
has recently estimated that the coal from the Uling field can 
be delivered at Naga at a cost of 5 pesos per ton, and that at 
least 800,000 tons are available. The analyses given in Table
