Part I.] Pearson: Seasoning of some Indian Timbers. 27 
relative merits of above two methods of seasoning can then 
be compared. 
(in) (a) To convert green logs of all the above 7 species into planks 
and season them, piled in open stacks with weights above. 
* Also to convert into planks the logs after they are seasoned 
according to methods suggested under (i) ( d ) and to 
compare their state, when dry, with the boards converted 
from green logs. 
(b) & (c ) In carrying out the above experiments special atten¬ 
tion will be paid to the question of discolouration of Bomhax 
malabaricum, the logs of which will have to be entirely 
immersed during the water-seasoning process. 
IV.—Central Provinces. 
The Chief Conservator of Forests and Conservators of Forests of 
the Central Provinces in their reports on seasoning timber lay special 
stress on felling in the rains and water-seasoning. The following experi¬ 
ments are proposed to be carried out in the Central Provinces with (1) 
Teak, (2) Terminalia tomentosa , (3) Pterocarpus Marsupium, (4) Lager- 
strcemia parviflora , (5) Diospyros Melanoxylon , (6) Ougeinia dalbergioides , 
(7) Terminalia Arjuna, (8) Adina cordifolia, and (9) Stephegyne parvifolia. 
(t) (a) To girdle 10 trees of each of the above species to determine 
the mode of seasoning by doing so. 
(d) Seasoning poles of the above species in water for 2 to 4 
months, and afterwards in open stacks in the shade, and 
placing a similar number of poles of each species to season 
in the shade without previously being immersed in water, 
this for comparison. 
(ii) (a) To fell poles of the above species in January, April and 
August or September, and place them to season, some 
with bark on and some stripped, stacked in open piles 
in shady places. 
(6) To ascertain the amount of moisture in the timber felled 
in January, April and August (a) at time of felling the 
trees mentioned in (ii) (a) and (b) when seasoned, i.e., to 
form an idea of the rate of seasoning. * 
(vi) In connection with (ii) (a) to study the effect on the timber 
of barking and not barking poles when seasoning. 
* Note :—The moisture tests will be carried out at Dehra Dun.
