CHAPTER II 
Method of Conducting Present Series of Experiments. * 
The experience gained in carrying out the original series of expe- 
riments clearly indicated the necessity of simplifying the scheme for 
further work so that more attention could be given to the things of 
fundamental importance, leaving the finer points for more intensive 
study. Moreover, the conclusions as regards some questions, for 
example, the necessity of sheltering the timber during seasoning, 
were sufficiently definite to make further tests unnecessary. In the 
second and present series the tests were reduced to four main expe- 
riments, namely : 
(1) Natural seasoning in the log under cover for 18 months 
followed by conversion and stacking for 6 months. 
(2) Green conversion and stacking for 2 years. 
(3) Green conversion followed by water seasoning for 3 months 
and stacking for 21 months. 
(4) Girdling for 12—18 months followed by conversion and 
stacking for 6 — 12 months. 
Each of the follovdng species was subjected to the four methods 
of seasoning in the localities noted: —
