Part I.] Pearson: Seasoning of some Indian Timbers. 
(7) Seasoning timber in the log with a saw-cut to the centre, with 
subsequent conversion and a further period of seasoning 
in the form of planks and scantlings. 
(8) Study of the question of discolouration, cracking, warping, 
contraction, degree and rate of seasoning, insect attack 
and decay of timber treated under the above methods ; and 
comparison of the relative degree of success attained under 
each method, with the corresponding results obtained by 
the method of treatment outlined in section (1) above. 
The extended scope of the scheme together with the number of 
species to be tested necessitated sub-dividing the experiment into several 
sections and distributing the work amongst different Provinces. This 
system had the advantage of allowing the timber to be seasoned under 
varying climatic conditions. 
The distribution was as follows :—
