Shwegyin and Toungoo a fair amount of girdling took place in the 
sixties and early seventies in some of the forests : there was, however, 
little or no working in the Bondaung, W. Swa, Sabyin and Lonyan 
reserves in the Toungoo Division. 
Chindwin forests. —The more accessible localities were heavily worked 
before the annexation, and have been steadily worked since : this ap¬ 
plies to the Kale and Mawku Working Circles, but a considerable portion 
of the Taungdwin forests have been little worked owing to their inac¬ 
cessibility. 
Ruby Mines forests. —These forests were very heavily worked before 
the annexation, only the more inaccessible localities escaping ; they 
have also been steadily worked since the British occupation. 
Madaya forests , Mandalay These forests were recklessly overworked 
in Burmese times. No enumerations have been made under the working- 
plan, but if enumerations were carried out they would no doubt reveal 
a large number of teak stumps. 
Mohnyin forest , Katha. —This forest, judging by the teak stumps enu¬ 
merated in valuation surveys, was worked over to some extent prior to 
the working-plan, but the working does not appear to have been exces¬ 
sive. 
Forests east of the Sittang. —The Ziyaing-Mehaw forests (Pyinmana) 
were in part worked over to a moderate extent prior to the enumerations, 
but part O' the area was practically untouched. In the Gwethe forest, 
(Toungoo) a considerable amount of girdling was carried out from 1869 
to 1873. 
Plains forests of ZigSn, Tharrawaddy and Rangoon. —The Kangyi 
forest was not very heavily worked prior to the enumerations, while the 
Satpok, Sitkwin and Thindawyo reserves were practically untouched so 
far as teak is concerned ; the same applies to the Rangoon plains forests. 
Thaungyin fores's. —A considerable amount of girdling and extrac¬ 
tion had been carried out prior to the working-plans enumerations. 
3. Methods of estimating the Growing-Stock. 
In the great majority of working-plans the growing-stock has been 
Sample plots estimated from enumerations in sample- 
plots scattered over the area in representa¬ 
tive types of forest. Generally these sample-plots are laid out in
