In the young 8 year-old plantation (Locality 1) no beeholes occur 
above 18 feet, and half of them occur between 3 and 6 feet. This fact 
is of some importance from the point of view of control; in the first 
thinning trees showing beeholes should be removed, and since half of 
the visible beeholes are likely to occur opposite the marking-officer’s 
eyes their detection is within practical limits. 
In the 22 year-old plantation (Locality 2) a concentration of the 
half the total number of beeholes is still within the first 6 feet, but above 
10 feet the beeholes suddenly thin out and steadily decrease in number 
to the crown. 
In the 21 year-old plantation (Locality 3) although about the same 
age, the distribution different; only 25 per cent, of the beeholes occur 
in the lowest 6 feet of the bole, and above this height the distribution 
is fairly even with a slight increase between 25-30 feet,
