(Hi) Cost of treating sleepers with Chloride of Zinc and either 
Green oil or Avenarius Carbclinevm oil. 
Before considering the cost of treating-each different species of timber 
and in order to clearly define the basis on which the calculations are 
made, it is necessary to state that the railway freight entered is that 
which was actually incurred on the whole consignments of both salt and 
oil, as it has not been found possible to split up the sum in proportion 
to the amount of antiseptic absorbed by the sleepers and that left over 
after treatment. In any case the amount was insignificant and would 
hardly affect the price when worked out to cost per sleeper. The cost 
of the oil is put at 6 annas 10 pies per gallon, which was the actual price 
paid; if purchased in bulk the price may be reduced, while the inclusion 
of the price of oil needed to flood the sleepers can hardly be considered 
a necessary item of expenditure, and has only been added to form a 
liberal estimate. And lastly, the labour bills must be considered as 
excessive, as the coolies were new to the work, while they also include 
the labour expended on erection of plant. Taking the above points 
into consideration, the cost of treatment works out as follows :— 
(a) Cost of treating 100 Pinus longifolia and 100 P. excelsa broad 
gauge sleepers, with Chloride of Zinc and Green oil. 
The Pine sleepers utilized in this experiment were supplied by the 
Chakrata Division, as were also those used in the Avenarius Carbolineum 
experiments. They were sound, well-seasoned sleepers, containing 
little twisted fibre though, in some cases, having been cut including the 
core of the tree. The figures given below do not include either royalty 
on the timber or on the treatment:— 
Cost of felling, conversion and extraction from forests to 
Jagadhri of 200 broad gauge Pine sleepers 
Cost of Chloride of Zinc to treat 200 broad gauge sleepers, 
absorbing 15 lbs. of a 2 per cent, solution at 6 annas 
per lb. concentrated ...... 
Freight on the salt from Calcutta to Jagadhri 
Cost of Green oil to treat 200 broad gauge sleepers, 4 lbs. 
per sleeper, at 6 annas 10 pies per gallon 
Freight on GrSen oil from Antwerp to Jagadhri, inclusive 
of oil required to flood them in tank 
Labour for treating, stacking, spreading, etc.. 
5 per cent, of cost of plant ...... 
Fuel ....... 
10 per cent., due to evaporation and leakage of oil . 
Miscellaneous charges ......
