They regarded it as about equal to grade “ G ” of American rosin, the market 
price of which was £21 to £22 per ton in London (July 24th). 
As indicated in Imperial Institute Report of the 5th July last these prices are 
much m excess of those ruling for similar rosin before the war, thus grade “ G ” 
of American rosin in July 1914 was worth £17 to £18 per ton. Even this price 
was rather high, the normal value being about £14 per ton.
