It was originally contemplated that 5,000 sleepers should be treated 
but, owing to the Powell Company in India closing down, just as the 
remaining Dipterocarp sleepers were on the point of being despatched 
from Burma, and also in a lesser degree to rejections of faulty sleepers, 
the experiment had to be considerably curtailed. 
(ii) Cost of Treatment. 
It is not possible to form a correct idea of the cost of delivering Powel- 
lized sleepers to a Railway Company, based on the experience gained 
in carrying out these experiments. In the first place, the cost of railing 
sleepers from Northern India or railing them to Rangoon and then 
shipping them to Bombay, was excessive. Were it contemplated to 
supply Powellized sleepers to a Railway in India or Burma, the obvious 
way to do so would be to erect the treating plant in the vicinity of the 
forest from which the sleepers were to be extracted or near the Railway 
line. Again, owing to the first batch of Dipterocarp sleepers having been 
converted green and some of the pine sleepers having been prepared 
from faulty logs, the number of rejections was unduly high and unless 
the price realized by selling such rejections be deducted from the cost 
of preparing the total number of sleepers, the figure of cost is incorrect. 
Experience was, however, gained in carrying out this set of experiments, 
which resulted in better methods of working being adopted in carrying 
out the second group of experiments.
