Part I.] Pearson : Seasoning of some Indian Timbers.

(i d) General remarks. —Mr. Parker, who carried out the finalTinspec- 
tion at Changa Manga, Lahore Division, states that in order to obtain 
really good scantlings it is advisable to reject the centre of the log in 
conversion. 
(12) Dillenia pentagyna (Appendix IV-12). 
(а) Locality where tested. —Kurseong Division, Bengal.] 
(б) Best method of seasoning. —The only method which gave satis¬ 
factory results was girdling the trees and leaving them standing for 
2 to 2J years, followed by conversion and seasoning under shelter for 6 
months. 
(c) Other methods of seasoning. —All other methods of seasoning 
produced rotten timber, with the exception of a small percentage of 
timber from logs seasoned in water and then on land. 
(d) General remarks. —This timber yields excellent rafters and boards 
for internal work, though it decays rapidly if exposed to excessive mois¬ 
ture. If quartered, it shows a handsome silver grain rendering it suitable 
for wainscoting and panelling. 
(13) Diospyros Melanoxylon (Appendix IV-13). 
(a) Locality where tested. —South Chanda Division, Central Provinces. 
(b) Best method of seasoning. —The best results have been obtained by 
girdling the trees and allowing them to stand for two years before felling, 
followed by 6 months’ seasoning in the plank or scantling. Trees allowed 
to stand for three years showed signs of insect attack. 
(c) Other methods of seasoning. —Slightly inferior results to those 
recorded above, were obtained by conversion from green logs, followed 
by immediate immersion of the rafters and planks in water for 6 to 8 
months, and subsequent seasoning on land for upwards to 18 months. 
Timber seasoned in the log, either with or without bark, split consider¬ 
ably, while the former was heavily attacked by Longicorn borers. Water 
seasoning in the log also gave poor results, both in respect to splitting 
and insect attack. 
(( d) General remarks. —This timber is not suitable for conversion into 
planks, though suitable for posts, rafters, shafts, etc. When converting 
the logs, the core should be either rejected or put aside for special 
purposes. 
(14) Duabanga sonneratioides (Appendix IV-14). 
{a) Locality where tested. —Kurseong Division, Bengal. 
(6) Best method of seasoning. —The best results were obtained by 
girdling the trees, and allowing them to stand for a year to a year and
