of unknown attitudes that at places project through the later 
cover or, perhaps, never were covered. 
The starting point for this cross-island trip was Wright, or 
Paranas; the latter is the town’s old name. Here there is a 
prominent cliff of typical marl, one specimen of which gave 
27.65 per cent silica in addition to its calcium carbonate content. 
These Samar marls are usually gray, compact, lignitic, slightly 
feldspathic, shalelike in appearance, and contain minute, deli- 
cate fossils, among which can be recognized, from the beds at 
Wright, Foraminifera, Dentalium sp., Natica sp., hinges of a ~ 
pelecypod, Nassa (?) young form, and Yoldia sp. (?). 
On the road from Wright to Loquilocan outcrops of marl 
only were noted, and the definite attitudes indicate a north-south 
strike with a gentle dip to the west. Massive limestone was 
found near Loquilocan. 
The hard, fine-grained red to brown fragments of jasper and 
chert that were noted in Ulot River point to the presence of 
chert and jasper in place—probably in the region near Lawaan, 
north of Loquilocan. No chert was seen in the streams that 
drain the west coast, and no quartzite at all was observed. It 
is interesting to note that some curious pottery and worked 
gold, which may be quite ancient, were found in the vicinity of 
Lawaan. 
For a distance of about 2 kilometers, the course from Loqui- 
locan to Bagakay was by baroto down Ulot River. Soon after 
we left the barrio, coal was noted outcropping on the bank of 
the stream. It is overlain by a very coarse, massive, gray cal- 
careous sandstone, and is adjacent to some badly crushed clay- 
shale. Faulting is evident here. 
In the bed of Ulot River, municipality of Wright, about 2 
kilometers downstream (east) from Loquilocan, there is a small 
outcrop of a hard, fine-grained, compact, blue-gray rock, which 
is unstratified and amorphous and breaks with uneven fracture. 
In the field this rock was called a quartzite, and even under & 
hand lens it is certainly very similar to that metamorphic rock. 
However, a microscopic examination under low power shows 4 
white thin section with black and white dots which are unchanged 
under crossed Nicols. The black components have a high re- 
fractive index. Relatively large phenocrysts of an indetermin- 
able feldspar occur in a fine-grained groundmass of eryptocrystal- 
line quartz, feldspar, and magnetite. This rock is a feldspar 
porphyry. ‘
