A comparison of the figures in cloumns 9 and 10 of Appendix IV should 
Logs yielded per tree. show the avera « e number of logs yielded per tree, 
but as a matter of fact the figures are not to be 
relied on because those in column 9 are, as stated above, not always 
accurate, while those in column 10 do not allow for loss in transit. 
The average volume per log will be found in columns 14 and 15 of 
Average volume per log. A PP endix IV - The size of logs yielded must of 
necessity depend greatly on the facilities for 
extracting large timber, and not only on the size of the trees felled. 
The largest average logs brought out so far in any one sub-period 
Large average logs. are the 6 ^ 9 lo % s f xtract ed from the Kangyi re¬ 
serve, Zigon Division, during the sub-period 1902- 
OS to 1905-06, which averaged 103 cubic feet. 
The following statement gives the names of forests from which the
