NOTE.—(i) Quality I over 120 ft. height. 
II from 90 ft. to 120 ft. 
Ill under 90 ft. 
(ii) Volume of logs all exploitable produce, and may therefore be used as volume of trees. 
(iii) Kulu average based on measurements of 7,700 Kulu trees exploited during last 20 years. 
(iv) Enumeration figures converted into volume according to figures for 3 7 classes. In felling against 
prescribed yield volume according to 1" classes will be taken. 
(v) Standard loss in converting logs into scantlings: 45 per cent. 
(vi) The Kulu average combines all the quality classes, and is for local application only. It is <o be n 
only for calculating the yield and money value of the outturn over a term of years and not for one pai 
cular forest. For this the yield according to quality should be used.
