An estimate of the profit on preparing 9,000 tons of mixed extract of

the factory, is attached :— 
Dr.

Thus in the manufacture of mixed extracts of good quality there is all 
likelihood of a profit of 27 per cent on the capital outlay. 
Messrs. Dumsney and Noyer show a profit of 30—33 per cent, on the 
capital outlay of R2,10,000 when dealing with chestnut wood containing 
8 per cent, tannin. This estimate is applicable to tan woods of India and 
Burma having a similar percentage of tannin. 
In the case of a small concern with a minimum output of 1J tons of 
extract per 24 hours, it has been found by the writer, based on his actual 
experiments that the capital outlay required will be R1,00,000, yielding a 
jxet profit of R16,000 per year, or 16 per cent.
