Using 15'3 per cent, as the moisture content, of thoroughly 
air-seasoned boards 1" thick in "February, it is evident from Appendix 
1 that each method has resulted in thoroughly air-seasoned timber 
in thicknesses up to at least 1" and green conversion up to . 
The climatic conditions of this Division are similar to those of 
Coorg, and the moisture content of air-seasoned timber is practically 
the same in both cases. The opinions as to the probable time required 
for air-seasoning in Coorg ' are directly applicable to the Wynaad 
Division. 
{xiv) South Mangalore Division, Madras. 
Four species of medium to high density were under test in this 
Division. The final inspection was carried out in February, 1922 at 
which time 18 moisture determinations were made. The average 
moisture content of 1" boards, which had been sawn from green logs 
and stacked in open piles for 30 — 32 months, was 14'9 per cent. The 
pieces from which these tests were taken were undoubtedly thoroughly 
air-seasoned for the region. 
From the record for this Division in Appendix I it is reasonable 
to draw the following conclusions : — 
(1) Hopea parviflora : — Seasoning in the log for 27 months 
followed by conversion and stacking for six months, 
. was insufficient to accomplish thoroughly air-seasoning 
for either 1\" boards or 4" x 4" scantlings. 
Girdling for 17 months, followed by conversion and 
stacking for 15 months, was sufficient for thorough air- 
seasoning of 14" boards at least. 
(2) Hopea Wightia^ia : — Seasoning in the log for 20 months, 
followed by conversion and stacking for 13 months, was 
sufficient for 1^" boards at least. 
Girdling for 16 months, follow'ed by conversion and 
stacking for 14 months, w'as sufficient for the air-season- 
ing of at least 1\" boards. 
(3) Hardivichia pinnata : — Green conversion, followed by 
stacking for 32 months, was sufficient for the thorough 
air-seasoning of 4" x 4" scantlings. 
Girdling for 18 months, followed by conversion and 
stacking for 13 months, was sufficient for at least IJ" 
boards. 
(4) Eugenia gardneri : — Seasoning in the log for 27 months 
follow'ed by conversion and stacking for six months, was 
insufficient for the thorough seasoning of either 4" x 4" 
scantlings or IJ" boards. 
Girdling for 15 months, followed by conversion and 
stacking for 15 months, w'as insufficient to accomphsh 
the thorough seasoning of 2" planks.
