11. Nature of tree or timber to be cut
No tree or timber shall be cut under a licence in Form 3 with royalty paid according to cubical measurement or according to number where shingles are being worked unless it be dead, wind-fallen, diseased, unsound or a remnant or unless the length of workable stem is less than 24 feet. All other trees must be paid for by girth measurement, save where specially authorised by the Chief Forest Officer for silvicultural reasons.
