2. Plantation No. 5 of 1899, Kaing Reserve. 
1. Description of Sample Plot. 
At the north-west corner of the plantation, near the Burma 
Forest School Sample Plot No. 11. The plantation (56 acres) is on 
the valley-flat and slopes of the same small stream as in the preced¬ 
ing plantation, but is still more cut up into small patches by the 
intrusion of Kaing grass, shrubs and bamboos. (An inspection note of 
1910 states that fully half should be written off.) The area from 
which sample trees were taken is in an isolated block surrounded 
by dense grass and shrub growth and high clumps of Bambusa 
polymorpha. 
Undergrowth. —At present, owing to a thinning, low, but previously 
high shrubby growth, which suppressed much of the teak early in the 
life of the plantation and caused the remainder to develope forked 
stems and low branching crowns. 
Past History. —Weeded 1900-1905 ; cleaned 1906-07 ; thinning 
and cutting back of bad trees in March 1912 ; thinning in February 
1919. Fire protected up to 1911 ; burned departmentally 1912-1917. 
Tn 1903,1905 and 1911 accidental fires occurred. 
2. Results of Analyses. 
Number of Trees Analysed —9. Date of Analysis —29th-30th April, 
1919. 
The trees were felled in February, 1919 in the thinning carried out 
in this plantation.

The arithmetic mean girth of the sample trees is 25 inches, and the 
arithmetic mean number of beeholes per tree is 4’25. Owing to the 
great variation in the values for the girth-classes it is necessary to combine '
