 Some attention was given to the size of tlie leaves in tlie 

 jung-lc. On tlie whole none were larger than those of Macaranga 

 triloba, which have an average size of 500 sqiiare cm. Those of 

 Ficus varied from 150 to 350 square cm. Others were measured 

 thus : — 



Tacca cristata on the average about 180 



Baccaurea . . 



Hevea hrasiliensis 



Tim onius n-allicliia n us- 



Cinnamoin inn iners 



A rth roplii/lhim diversifoli

These are only a few measurements and a vast array must be 

 collected sooner or later by botanists in order to estabish the 

 relationship of size of leaf to t^^^es of forest. 



It has been said aibove that fruit trees had been planted over 

 the ground before the secondary jungle was allowed to spring up. 

 The presence of these trees complicates the history somewhat, but 

 the changes of the vegetation may have been as follows : — 



1st stage. Fruit trees standing in Lallang grass {Imperafa 

 arundinacea) . 



2nd stage. Melastoma malahathricum, bird dispersed, sprang 

 up through the lallang, followed by the equally l)ird distributed 

 Bliodamnia trinervis and Fagraea fragrans, while through monkeys 

 visiting the fruit trees all manner of just edible fruits that the 

 monkeys feed on Avere drop]ied about them. 



3rd stage. In a ring round the fruit trees with their roots 

 partly in the damper soil under the fruit-trees' shade, and their 

 leaves just beyond the shade, sprang up Eugenias, Sj/mplocos fas- 

 cicidata, Timonius, Cinnamoinum iners, Arthrophj/Uum diversi- 

 foUum. Of these by its quicker growth Artliroph yllum prospered.
