Up to 10 feet in girth the figures may be taken as fairly representative, 
but above that the number of stumps on which countings were made is 
hardly sufficient to give reliable figures. 
(3) Diagram showing rates of growth in girth. 
The diagram on plate VII shows at a glance the rate of growth in 
girth of teak trees, as follows :— 
(1) The fastest recorded growth of an individual tree. 
(2) The fastest average growth for a whole forest (Kangyi 
reserve). 
(3) The average growth for the whole of Burma. 
(4) An example of one of the slowest average rates of growth for 
whole forests (Minbyin reserve, dry forest only). 
(5) The slowest recorded growth of an individual tree.
