As compared with similar oils such as Carbolineum and Jodelite, the 
penetrating power of Green oil is greater, while the oil is considerably 
cheaper. In this case, as in former experiments, the amount absorbed by 
all the softer species, with the exception of Picea Morinda, was excessive. 
Cost of Treatment. 
The cost of treatment of a B. G. sleeper is based on the percentage 
of absorption given in the above table. The superficial measurement of 
a B. G. sleeper is taken as 24‘4 square feet and its volume as 3*3 cubic 
feet. The cost of the solution, if bought in parcels of not less than 10 
tons, is 6 annas per gallon f. o. b . Hamburg, while the freight per 
gallon to Karachi comes to 1*3 annas. One gallon weighs 9'6 lbs., 
therefore cost per oz. comes to 0'0±7 anna.
