Section 8. — Fike Protection. 
Under this head it is only proposed to consider the influence of fre- 
quent forest fires on the volume and money development of the Sal, 
since purely sylvicultural questions lie outside the scope of this inquiry.* 
Sample plots to determine the relative rate of the mean annual girth 
increment in burnt and in unburnt middle-aged and old Sal woods have 
been prescribed from time to time, notably in the Tirsal and Molawalla 
reserves of the Siwalik Division, and elsewhere ; but no data tending to 
elucidate the problem are at present available : and experim.ents bearing 
on very young trees or seedlings 1—3 year old have never been under- 
taken. 
The effect of forest fires on the development of the money value of 
Sal woods, more especially as regards the quality (value) of the timber 
produced, has not been brought under investigation. 
*Mr. S. Fardley-Wilraot’s Note on the Sal (op. cit. page 4 ) may be consulted in 
conjunction with the remarks contained in the Resolution on Forest Administration in 
Assam during 1905-1906.
