(c) Analysis of Raipur stick-lac from which the larvae swarmed oui 
while the lac was still on the tree. — “ The sample of lac from 
Raipur, Central Provinces, collected after the swarming of the 
larvae had the following composition . — 
Volatile matter . 
Resin

‘ ‘ This is a good lac and richer in resin than any other kind I have ex- 
amined. The ratio of colotir to the insoluble albuminous 
matter is 26'9 to 100, almost the same as that found in the 
Siwalik sample (27 T).” 
From Dr. Hooper’s analyses, as given above, it would appear that the 
swarming of the larvae from the lac does not remove all the colouring matter 
from the incrustations and that the washing processes to free the seed- 
lac from the colouring matter will have to be undertaken under any 
circumstances. 
CHAPTER XIII. 
STEPS TO BE TAKEN TO INCREASE THE PRODUCTION 
OF LAC. 
Formerly the lac industry was entirely in the hands of private indivi- 
duals, the stick-lac being collected from private lands and reserved forests 
in British territory and from Native States, amongst which latter Rewah 
may be mentioned as the chief. The right to collect the lac in unreserved 
forests was sold to the highest bidder, whilst in private lands the large firms 
interested in the substance obtained leases for a term of years, from five to 
ten, which enabled them to increase, by cultivation, the ordinary yield. 
Somewhere about twenty years ago Government began to turn their 
attention to this valuable commodity from which, in spite of the large size 
of the exports, they derived a very insignificant revenue. The Forest 
Department in the Central Provinces took up the question of the formation 
of lac preserves, and these have been continued and enlarged up to the 
present date.
