A. — Acres under turpentine, 1,984 ; acres counted, 382 ; affected trees 

 on total acreage, 36.4; total scale of affected trees on entire acreage 

 turpentined. 21,389 feet; affected trees to the acre (average). .0183; 

 per cent of entire stand affected, .117. 



It is to be noted that the damage from the turpentining is negligible. 

 This is not at all remarkable, since the timber had not been worked 

 enough to develop the full injuries received. This area was cut over 

 (luring the following spring and summer. In examining the timber a 

 20 per cent striji system was used, and all dead or dying trees were 

 noted. In determining the cause of the death of cupped trees, the 

 careful examination of each individual tree was necessary. There are 

 many causes that conspire to injure green timber besides the injury 

 from tapping. Ordinary decay accounts for the death of many trees 

 each year in a forest so matured as this one. Lightning also takes a 

 heavy toll, both directly and indirectly, for each tree killed by lightning 

 serves as an incubator for hordes of timber-borers. Some old decay- 

 ing trees fall a victim to the assault of the chipper after various periods 

 of resistance. In many cases such trees are a distinct gain, as their 

 lumber value would have been nil even had they lived. 



At the beginning of the season of 191 7, 6.299 acres of virgin timber 

 were cupped. An examination of the acreage at the end of the season 

 showed the following results : 



B. — Total acreage under turpentine, 6.299 ; acres counted. 825 : 

 affected trees, 16 : aff'ected trees to acre, .0222 ; number on total acreage. 

 138.57; average merchantable contents of each affected tree, 318; 

 average log scale of affected trees, 6.996 : total log scale affected on 

 entire acreage turpentined, 44,067 feet ; per cent of entire stand 

 affected, .00061. 



During the season of 1918 our plan for dropping part of the turpen- 

 tine area for the loggers and tapping the balance for another season 

 went into effect. At this time the labor problem became very acute 

 and the progress of the work was greatly reduced. However, we were 

 able to hang aprons in the new territory up to the original requirements 

 of our program. An examination at the end of the first season gave 

 the following results : 



C. — Total acreage turpentined, 3,999; acres counted, 626; affected 

 trees. 32; scale of trees after reduction of defects. 17.418 feet; number 

 of trees affected to acre (average). .051 ; number of affected trees on 

 total acreage, 203 ; average merchantable contents of each affected tree, 

 544 feet ; average log scale per acre of affected trees, 28 feet ; total log 

 scale affected on entire acreage turpentined, 110,432 feet; per cent of 

 entire stand aff'ected. .0032.
