seasoning in the plank. A reference to Appendix IV will 
show that in no instance was splitting serious, though attack 
by borers was in some cases severe. 
(ii) Pole wood. —Poles were felled in January, April and August, 
while others were felled in January and at once immersed in 
water. In all cases, the results were equally satisfactory. 
(c) Other methods of seasoning 
(i) Timber from the log. —Slightly inferior to the results enumerated 
above, were those obtained by immersing the logs in water 
for three months and seasoning for a year on land, followed 
by 6 months’ or more seasoning in the plank. The South 
Chanda Experiments show that if the timber is seasoned in 
the log, it must be barked ; otherwise, it is very liable to 
attack by borers. The season of felling does not appear to 
affect the timber, nor do the results of other, experiments 
differ very much from those already mentioned, as this 
timber is not liable to excessive splitting. 
(ii) Pole wood. —Nil. 
(d) General remarks. —Internal defects especially near the centre 
are very common in this timber ; it, therefore, follows that the core' 
should be rejected in conversion. The timber should be stored under 
cover to preserve its good appearance and colour. This timber produces* 
excellent cart-shafts, axles and building material from the log.and^ood 
poles and posts from small trees. 
(23) Pinus longifolia (Appendix IV-23). 
(a) Locality where tested. —Rawalpindi and Kangra Divisions, Punjab. 
(b) Best method of seasoning. —The best results have been obtained 
both in Rawalpindi and Kangra by converting green logs into sleepers, 
scantlings and boards. A period of not more than 12 months’ seasoning 
for converted material is advocated : the timber should preferably be 
carried out under cover. 
(c) Other methods of seasoning. —Seasoning in the log, with or without 
ends treated, has given quite good results in some cases and bad in 
others; though, generally speaking, cracking is more prevented than 
in the case of timber cut from green logs. Barking logs has. a bad 
effect, resulting in excessive splitting and often serious damage by borers. 
Mr. Wright, who inspected the Kangra experiment, states that by 
removing the bark from logs the oils and resins evaporate quickly and 
thus remove protection from insect attack. The material converted 
from green logs, on the other hand, exudes much resin at the ends
