this is Mount Balantoc. In the foreground are the lower slopes 
of the main cone. The vegetation on Mount Binintiang Malaqui 
is largely Themeda gigantea and Saccharum spontaneum. The 
remainder of the vegetation shown consists very largely of an 
open stand of Saccharum. On Mount Balantoc are seen a con- 
siderable number of scattered trees. October, 1916. 
PLATE XII 
Fig. 1. The central region of the northern part of Voleano Island, from 
the crater rim where Mount Pinag-ulbuan joins the main cone. 
The prominent peak on the right is Mount Mataas-na-golod. On 
the extreme left is Mount Tibag. The vegetation throughout 
is very largely an open stand of Saccharum spontaneum. October, 
1916. 
2. The northwestern slopes of the southwestern peninsula of Volcano 
Island as seen from Malanao Point. On the right is Mount 
Binintiang Munti; on the left, Mount Saluyan. The dark spots 
represent scattered trees. The remainder of the vegetation is 
very largely an open stand of Saccharum spontaneum. On ac- 
count of the distance at which the photograph was taken the 
bare ground between the clumps of Saccharum is not shown 
plainly. October, 1916. 
PLATE XIII 
Fic. 1. View of the southern portion of Volcano Island from Calauit Point. 
In the distance is the crater of Taal Volcano, the high portion 
on the left being the southwestern part of the rim. The vegeta- 
tion consists almost entirely of very scattereing clumps of Sac- 
charum spontaneum. October, 1916. 
2. The prominent dry stream bed, extending southwest from the 
southwestern part of the rim of the crater. In the picture is 
seen that part of the stream bed where it curves around Mount 
Saluyan, the lower slopes of which are to the right. The effects 
of erosion are very evident. No plants occur in the dry stream 
bed. Elsewhere the vegetation consists almost entirely of very 
scattering clumps of Saccharum spontaneum, there being only 
- about six shrubs visible in the picture. October, 1916. 
PLATE XIV 
Fig. 1. A déltal fan on the western side of Volcano Island. View from 
near Pandac-na-lohgos point toward the southeast. In the back- 
‘ground on the left is the southwestern part of the rim of the 
crater; on the right is a low ridge, behind which can be seen 
a portion of the flattened top of Mount Tabaro. In the center 
of the picture is a dry stream bed running through the deltal fan. 
The only vegetation seen on the fan consists of very few scattered 
clumps of Saccharum spontaneum. On the low hills in the 
distance scattered clumps of Saccharum are more numerous.
