4. Minor Products. 



In an analysis of liquid extract obtained from the bark from Coorg 

 the percentage of dry extract was found to be I'l, the percentage of 

 tannin '31, and the percentage of tannin in the dry extract 28'1. It is 

 noted by M. Rama Rao as an associate of Sandal, but root attachments 

 between the two have not been found. 



5. Natural Reproduction and Rate of Growth. 



Natural reproduction is reported to be generally good, though often 

 scattered. Foulkes in " Notes on Timber Trees in South Kanara " 

 says : " Natural reproduction uncertain and this species must be rigidly 

 protected from fire as the seeds fall in the middle of the fire season : 

 the seedlings too are especially susceptible to damage from this cause. 

 Will not germinate in poor soil exposed to the sun but requires one that 

 is deep, moist, and stiff : owing to the minuteness and consequent light- 

 ness of the seed it would seem to be advantageous to remove all dead 

 leaves prior to the fruiting season in order that the seed may come into 

 immediate contact with ,the mineral soil. The seedlings appear to require 

 three years to establish themselves, and once established, are hardy/' 



Bourdillon says the growth is fast in favourable circumstances, young 

 trees showing as much as 10 inches diameter in 11 years. 



Experiments on coppice growth made by Mr. H. Murray in Belgaum 

 in 1894 gave the following results. Three or four trees were examined 

 and the data determined for each age, mature trees between 38 and 44 

 years being selected.
