ail probabilities, be financially sound to add another 8*2 lbs., or a total of 
12 lbs. of oil, and thus raise the price of the treated sleeper to Rs. 5-4-6. 
As regards Pinus excelsd sleepers, their market value is from Rs. 3-8-0* 
to Rs. 4-0-0 each at Jagadhri, at which price they find a ready sale, so* 
it follows that to treat this species of timber is hardly profitable. 
(b) Cost of treating 400 Dipterocarpus tuberculatus and 400 D. alatus 
metre-gauge sleepers. 
As has been stated elsewhere, some of the Dipterocarp broad gauge 
sleepers destined to be Powellized were not utilized for that purpose 
they were, therefore, converted into metre-gauge size for this experiment. 
The number was, however, insufficient; so metre-gauge sleepers were cut 
direct from the logs to make up the deficit. In the following calculations, 
the cost throughout has been assumed to be that of cutting direct from 
the log into metre-gauge size, otherwise the figure arrived at would be 
entirely misleading.

The cost of landing a treated Dipterocarp metre-gauge sleeper on 
rail amounts to Re. 1-9-2, exclusive of royalty on the timber or on treat¬ 
ment, and this with only IT lbs. of the oil to protect the timber. From 
experience gained since these experiments were carried out, it is considered 
that IT lbs. of oil is quite inadequate to protect the timber for any length 
of time * to make the process effective the amount of oil will have to be 
increased to at least 9 lbs. per metre-gauge sleeper or 6 lbs. per cubic 
foot. This could not be done with Avenarius Carbolineum oil alone, 
as the cost would be prohibitive. A means of cheapening the oil would 
have to be found as, for instance, by mixing it with a cheaper solution 
such as Burma Earth oil. How long IT lbs. of the oil will protect the 
sleepers will be demonstrated by the sleepers so treated and now in the: 
line.
