THE FLORA OF MOUNT PULOG. 293 
coast range. There is, however, no direct evidence on this subject, and 
the deeply gullied slopes of the mountain bear evidence of torrential 
rains. 
The following rather incomplete weather notes were taken by the 
Forestry Bureau party : 
January 1—(Agno River). Dry; light clouds. 
January 2.—(Agno River to 1,500 M). No rain; sky nearly clear all day; 
light mists and clouds after 5 p. m., and more or less all night. 
January 3.—(1,500 m to summit). Alternately clear and misty in the fore- 
noon; continuous heavy mists after 10 a. m., and all night. 
January 4.—(Summit). Mists all the forenoon; clouds breaking away in the 
afternoon; mists at night. 
January 5.—(Summit). Clear all day. ° 
January 6.—(Summit). Generally clear, with light clouds. 
January 7.—(2,100 m). Fair weather; light clouds at times. 
January 8.—(2,100 m to Agno River). Clear weather. 
The weather during the ascent in May, 1909, was similar to that 
noted above, but one afternoon rather heavy rain, with considerable wind, 
was experienced. In July, Mr. McGregor experienced light showers the 
first day, the second and third days the summit was clear in -the 
morning and more or less misty all day after about 9 a.m. In general, 
so’far as observations made on such short trips are of value, the mountain 
seems to be clear in the morning, becoming enshrouded in clouds at 
about 9 a. m., and continuing more or less in this condition the remainder 
of the day. 
The top of Mount Pulog is a high, rolling plateau, including perhaps 
between 1,500 and 2,500 hectares. Near the north-central part of this 
area a higher knoll rises about 250 m above the general level to form 
the extreme summit. From this grass-covered plateau the sides, which 
are covered with dense thickets, fall off abruptly, as a literal inter- 
pretation of the name “Pulog” implies. So steep are these slopes, 
in fact, that a collecting party sent out by the Forestry Bureau ex- 
pedition, although accustomed to all kinds of mountain climbing, was 
forced to turn back from one of the slopes, after descending to an altitude 
of about 1,800 m, the loose crumbling earth making further progress 
absolutely dangerous. Other slopes appeared to be quite similar to 
this one, except the one extending eastward toward the Agno River, 
_ which is less steep. 
In most places the soil is fairly deep, apparently formed for the 
greater part by the rapid decomposition of rock in place. Outcropping 
ledges are the exception, although some low cliffs are to be found, and 
boulders are common in ravines and gullies. The rock formation, at 
least of the summit, is andesite. 
The view from the summit of Mount Pulog, which is uninterrupted 
in all directions, is probably unsurpassed in the Philippines. Directly to 
the north the distant view is obscured by the comparatively high peaks
