as such and is manufactured to contain io to 12 per cent, rosin. 
Calcutta brokers blend this with pure TN to make a 3 P er cen h 
mixture which is a standard in London. The quality clause in the 
standard form of contract adopted by the London Shellac Trade 
Association runs as follows :— 
“ Guaranteed to be of equal value to standard sample of TN and 
not to contain more than 3 per cent, of adulterating matter or if 
inferior thereto a fair allowance to be made.” Similarly, the New 
York market recognizes “ordinary pure TN ” which must, however, 
be free from rosin ; but has established, in addition, a grade known 
as “ Ussa TN ” containing 3 per cent, of rosin. 
Superior to TN is Standard I, another non-proprietary mark. It 
is only a clean grade of TN and differs from it in no other essential 
except a slightly better colour and fewer impurities. It contains no 
rosin, and fetches three to five rupees more than clean TN. TN and 
Standard I are manufactured only from Baisakhi and inferior lacs, 
and not from Kusmi. The better Baisakhi is used for Standard 
I while poor Baisakhi, Katki and rejections from fine grade manu¬ 
facture are used for TN. The bulk of the TN and Standard I is 
made in small factories. The larger factories usually make better 
qualities and only makeTN when they cannot get good stick-lac 
or wish to use up their rejections. 
Superior to Standard I are the “Fines” and “Superfines”—- 
practically all proprietary marks. They are usually manufactured 
from the very best Baisakhi lac with or without a proportion of 
Kusmi, while the very finest grades are made from pure Kusmi. The 
following are well-known marks of this class, as quoted by Messrs, 
Moran in their weekly statement:—
