species that are also planted on the campus below. Some others 

 he learns as to the genus, such as Dillenia and Ficus, while the 

 vast majority of individuals away from the trails and unlabeled 

 are completely unknown. 



In the lower two-thirds of the mountain slope, the forest is 

 composed of tall trees, usually with a second or even a third 

 story of lower trees beneath them. A good proportion of the 

 individuals belongs to the Dipterocarpaceae, so that the whole 

 forest type is called the dipterocarp forest. The trees have tall 

 straight trunks two to five feet in diameter, with their branches 

 appearing at a great height. The smooth light-colored bark is 

 generally characteristic. The leaves are at so great a height, 

 and the forest cov^er is so tangled with lianas that it is difficult 

 to form any idea of the general leaf character. Now and then 

 one finds on the ground flowers or fruits which indicate the near 

 presence of some familiar genus. At the time of our visits, 

 the fruits of Dillenia were especially common. They are green 

 in color, spherical in shape, and about the size of a lemon. The 

 outside is composed of the enlarged green sepals, enclosing 

 within a twisted mass of juicy carpels. Stripped of their sepals, 

 the carpel mass is edible, and tastes somewhat like exceedingly 

 sour and juicy apples. In the absence of drinking water, they 

 are useful for quenching thirst. In other places one finds 

 the fruits of nutmeg, with an oblong seed surrounded by the 

 network of mace, or even acorns from some of the tropical species 

 of Quercus. 



Palm trees are not common. Here and there one meets with 

 a slender fan palm twenty to thirty feet high, but they are so 

 rare that they never constitute an important part of the forest, 

 and from most points along the trail no palms are in sight at all. 

 This does not include the rattans, species of the genus Calamus. 

 These climbing palms are common everywhere through the for- 

 est, stretching to immense distances but never getting very high 

 above the ground. Their trunks, including the bristly leaf- 

 sheaths, may be six inches in diameter, and at the base are re- 

 clining on the ground. Farther out they ascend obliquely into 

 some tree, and thence may be traced looping away from one
