Part IV.] R. S. Pearson: Antiseptic Treatment of timber . 23 
In consideration of the above facts, the following calculations are 
based on the actual number of treated sleepers handed over to the Rail¬ 
way Companies, had they been delivered on rail near the forests from 
which they were obtained ; in other words, leaving out of account freight 
to and from Bombay. 
Royalty charges on the timber are also excluded from these estimates.

The above figures do not represent what was actually spent on these 
experiments, as they exclude the cost of preparing sleepers which had 
to be rejected and which were afterwards disposed of at a profit. 
The point of primary interest is the cost of putting a treated sleeper 
on the market. Based on the above figures, the price comes to Rs. 2-0-7 
per B. G. Pine sleeper, to Rs. 3-5-3 for B. G. Dipterocarp 
sleepers, and to Rs. 3-5-2 for B. G. Terminalia tomentosa sleepers.
