Comparing the above figures for Jodelite with those obtained for 
Avenarius Carbolinezm (page 58) the quantity absorbed is slightly less ; 
in other words, the penetration has been on the whole not so deep, the 
only noticeable exceptions being Nos. 1 and 13. both soft woods. Here 
again, the harder species have not been left long enough in the solution 
to afford proper protection to the timber. 
Cost of Treatment. 
The cost of treating a B. G. sleeper is calculated on the above per¬ 
centages ot absorption. The superficial area of a B. G. sleeper is taken 
as square feet, and the volume as 3*3 cubic feet. The cost of the 
solution landed at Karachi, including freight and duty, is taken as IB-11 
per gallon and its weight as 10 lbs. 14*5 oz, per gallon. The cost of 
processing is put at 1 anna per sleeper.
