The girdling of this species is not recommended because of the 
liability to severe damage by borers both in sapwood and heartwood. 
From this it may be concluded that seasoning in the log is also 
hazardous due to insect attack. 
(14) Oareya arborea (Appendix I — 14). South Chanda Division, 
Central Provinces. Gonda Division, United Provinces. Ganjam 
Division, Madras. 
This species is to be classed among the most refractory woods. 
It seasoned with as much damage from surface cracking, splitting, 
cupping, and twisting as any other species under test in these 
experiments. However, the material in eaph case was small and 
generally defective. 
Although the few pieces of good material seasoned fairly well, 
the timber as a whole seasoned with considerable depreciation. 
Slight damage by borers was done to logs held for seasoning in the 
Gonda and Ganjam Divisions, and a certain amount of material 
under the water seasoning experiment was decayed due to storage in 
a badly ventilated shed. Discoloration in the logs or converted 
timber was entirely absent. 
• Girdling gave considerably the best general results both in the 
Gonda and South Chanda Divisions largely because of the reduction 
of surface cracking. In Ganjam there was little difference between 
girdling and green conversion. 
Seasoning in the log, although involving a little damage by borers 
in the Gonda Division, reduced the surface cracking and gave results 
second to those of girdling. In the South Chanda and Ganjam 
Divisions seasoning in the log resulted in the most smface cracking, 
and gave the poorest general results. 
Green conversion, except in Ganjam Division, and water season- 
ing gave approximately the same results, both methods resulting in 
considerable surface cracking and cupping. 
The most characteristic seasoning defects of this species are 
cracking, splitting, cupping, and twisting. The elimination of these 
defects depends pinmarily on the protection of the converted timber 
either from fresh or partially seasoned logs against too rapid drjing 
and also upon careful stacking. This species should be converted 
during or near the end of the rainy season. 
(15) Oassia Fistula (Appendix I — 15). Gonda Division, United 
Provinces. 
This timber is to be classed as a refractory wood subject to severe 
damage by surface cracking, cupping, and splitting. There was a 
■slight amount of damage done by borers in the sapv/ood of both logs 
and converted stock. The species is liable to borers in the living tree 
and to sevei’e damage in the sapwood if the bark is left on. There 
was no evidence of decay even in those boards which were stored in 
a poorly ventilated shed.
