Green conversion gave the best results, inasmuch as the cracking 
and splitting were minimized. ■ 
Girdling gave somewhat the poorest general results due to a 
greater amount of surface cracking and splitting than in the other 
methods of treatment. However, the timber so seasoned was not 
as good originally as that dealt with under the other methods. 
This species is obviously not exacting in its seasoning require- 
ments, and may be expected to give very good results by almost any 
method, providing ordinary precautions are taken in the care of the 
logs and the converted timber. 
(10) Boswellia serrata (Appendix I — 10). South Chanda Division, 
Central Provinces. Porahat Division, Bihar and Orissa. 
The pieces representing this species seasoned very poorly, 
particularly in the South Chanda Division, in that the wood was 
severely damaged by decay, mould, and discoloration, as well as by 
white ants and borers. Other defects such as cracking and twisting 
were of minor importance in comparison, although severe splitting 
was a marked characteristic of the seasoning in the Porahat Division, 
probably due to delay in conversion. 
The material seasoned in the log was absolutely useless because of 
decay and white ant attack, and severe splitting in the Porahat 
Division. 
The girdled timber was somewhat less decayed but was damaged 
by small borers and was largely worthless. 
Even green conversion, which might be expected to eliminate 
decay and mould, gave very unsatisfactory results. It will be noted, 
however, that the logs were not converted for two months after 
felling, which probably accounts for the depreciation. 
All of the material in the South Chanda Division was converted 
during the rainy season. The results from the Porahat Division 
indicate that much of the mould and decay may be eliminated by 
green conversion during the dry season immediately after felling, 
followed by open stacking. 
(11) Bursera serrata (Appendix I — 11). Ganjam Division, kladras. 
The general results from the. seasoning of Bursera serrata were 
fairly good, in spite of the pronoimced surface cracking recorded at 
inspection. The cracks were numerous, but small and inconspicu- 
ous; and did little serious damage except in the case of the timber 
which was water seasoned. Splitting was not serious. The cupping 
which occurred was due entirely to the piling. The sapwood was. 
somewhat damaged by fungi, white ants, and borers, but the heart- 
wood was practically immune. ,
