Inasmuch as the climatic conditions of the South Chanda Division 
are not unlike those of the Gonda Division and the moisture content 
of seasoned timber is practically the same in both Divisions, the 
opinions expressed on page 50 as to the time required for seasoning and 
the ultimate moisture content of air-seasoned timber are generally 
applicable to both Divisions. The heartwood of Odina Wodier and 
Hardwickia binata is very slow drying and the indications are that it 
will not air-season completely in 1" boards in less than 12 — 15 months 
after conversion. 
(m) D.\RJEELixa Division, Bengal. 
There was only one species under test in this Division. The mois- 
ture content determinations were made in February, 1921, when the 
humidity was normal for the month. Even though the calculations 
are based on 1'^ boards which had been converted and stacked for 24 
months, there is considerable doubt as to whether the timber was 
thoroughly air-seasoned at 20'4 per cent, in view of the fact that most 
of it was crib-piled without crossers in a closed brick building. The 
atmospheric conditions in this godown must have been considerably 
different from the normal outdoor conditions of the regfion. The 
O 
probable normal variation in moisture content of seasoned timber in 
this locality is from 24 — 26 per cent, in the rainy season to about 15 
per cent, in April and May. 
(iv) Buna Division, Bengal. 
The calculations as to the moisture content of air-seasoned wood 
in this Division are based on 51 determinations upon two species, made-
