[VoL. IX 
The timber had probably passed the point of extreme dryness and 
had begun to show the effects’ of the higher atmospheric humidity 
conditions of the beginning of the rainy season. However, it was 
well below the mean of wet and dry season conditions. 
The average moisture content of 1" boards, which had been con- 
verted from green logs and stacked in open piles for 30 months, was 
8'9 per cent. The same timber probably would have tested 1 or 2 
per cent, lower at the end of the dry season and somewhat higher at 
the end of the rainy season. 
Taking 8' 9 ( 4 - 1‘5) per cent, as the average moisture content in 
July of thoroughly air-seasoned boards 1" thick it is evident from 
Appendix I that each of the methods has produced thoroughly 
seasoned wood in 1'' boards at least. There is a question as to 
whether the 30 months of seasoning after green conversion was suffi- 
cient for X 2^" scantlings. The data at hand is not sufficient to 
answer this question one way or the other. Limited knowledge of 
the seasoning of Albizzia indicates that it is a fairly slow drying 
timber. However, further investigation may show that 11 '8 per cent, 
represents the air-seasoned condition for 2|" x scantlings in this 
region better than 8’9 per cent. 
Albizzia siipulata in 1" boards, at least, can probably be thoroughly 
air-seasoned in the 6 — 8 months of one dry season. 
{xi) H.-vzAR.-i Division, N. W. F. Province. 
Two species were under test in the Hazara Division. The cal- 
culations as to the moisture content of air-seasoned timber in this 
Division are based on 28 tests on the two species. The determina- 
tions were made in June, 1921 and should truly represent the extreme 
of dryness to which seasoned timber in this region will come at the 
end of the dry season. The moisture content of 1" boards, which 
had been converted from green logs and stacked in open piles for 25 
months, was 4‘8 per cent. The average moisture content of 6'' x 4" 
scantlings, which had been seasoned in the same way, was 5‘6 per 
cent. There is every indication that each method of seasoning as 
shown in Appendix I for this Division was sufficient to accomplish 
complete seasoning for both 1" boards and 6" x 4" scantlings. The 
moisture content of thoroughly air-seasoned timber, particularly in the 
thinner dimensions, would be considerably higher (14 — 16 per cent.) 
after the wet season, but probably no lower than 4' 8 per cent, at 
any season. 
Both ash and walnut can probably be air-seasoned in 3 — 6 months 
between January and June in 1'' boards, and in thicknesses up to 
ly, at least, in 7 — 9 months between September and June. 
{xii) CooRG. 
There were nine species under test in Coorg including woods of 
both high and low density such as Hopea parviflora and Vateria
