front veranda of Dr. Gates's house were a number of trees of 

 ipul-ipul, Leucaena glauca, in common use here for firewood. 

 These trees were less than a year old, and- had been cut down to 

 the ground in June, four months before our arrival. During 

 that inter\-al they had grown fifteen feet high, and were full of 

 flowers, green fruit, and ripe pods. A young tree of teak, Tec- 

 tona grandis, planted in 1912, had during the rainy season of 

 that year grown eight feet, producing fourteen internodes of 

 from three to ten inches in length. In the following dry season 

 it had produced fourteen more internodes, half an inch to an 

 inch and a half long, amounting in all to one foot. During the 

 rainy season of 1913 it had alread}' produced nineteen internodes, 

 the lowest a foot long and the uppermost not yet fully elongated, 

 but the total length was already ten feet. 



It is quite probable that there is no place in the world where 

 the tropical forest can be observ^ed under more favorable cir- 

 cumstances than on the slopes of Mt. Makiling. This extinct 

 volcano rises immediately behind the campus of the College of 

 Agriculture, and reaches a height of somewhat more than 3,700 

 feet. An excellent trail has been constructed from the campus, 

 leading past the residences of the faculty', across the Malawin 

 river, and thence into the deep forest. After crossing the river, 

 the trail has several branches, so that one can use different routes 

 to and from the summit, and can easily visit various situations 

 on the flanks of the mountain. The value or the necessity of 

 carefully made trails will hardly be appreciated by one who has 

 never been in a real tropical forest. With the trails, one can 

 easily walk to the summit in three or four hours; without them 

 it would probably require two full daj-s. Along the trails, the 

 botanists and foresters have placed labels on many of the trees, 

 giving the native and scientific names and also the name of the 

 family. The mountain side is accordingly converted into a 

 natural botanical garden, where the botanist can observ^e at 

 his ease the vegetation in its original condition. One can easily 

 find the labeled plants in such gardens as those at Buitenzorg 

 and Peradeniya, or by sufficient exertion he can fight his way 

 through the virgin forest elsewhere. Here, however, one finds
