The tallest Macaranga triloba was 45 feet; and it and others

 trees. However large and old, these Macarangas were tenanted by 

 ants. 



Melastoma malabathricum, had long lost its hold upon the 

 ground. 



The means of analysing this jungle over the whole two acres 

 being wanting; two areas were taken respectively of 5800 and 7880 

 square feet or together nearly one third of an acre. The areas 

 were defined by means of wires, and then from each in turn (1) 

 the six foot high or lesser woody plants were removed, and deter- 

 mined. (3) the 6-18 feet high woody plants and (3) the trees. 

 The plants not attaining two feet were not counted but their num- 

 ber was estimated. Adding the two areas together, there were on 

 this area of nearly one third of an acre: —
