Protection of green logs . 



When prepared for floating : 



For immediate use during the summer, fell trees, leave tops on until 

 the foliage dries; remove logs from the woods and utilize at once. 



When not prepay ed for floating: 



(1) Provide for as little delay as possible between the felling of 

 the green timber and its utilization for lumber or submergence in water. 



(2) Remove logs from the woods as soon as cut during the period 

 of insect activity and transport to a place of safety.
