smallcr logs. The International %-inch rule closely 

 approximates green-lumber mill tally, and is used 

 throughout this report to express green-lumber 

 tally in the more detailed tables of volume and also 

 in the calculations of saw-timber growth and drain. 

 As shown in table 11, the total net saw-timber 

 volume, lumber tally, for south Georgia, as inven- 

 toried in 1934, was about 18.5 billion board feet. 



As inventoried in 1934 and shown in table 12, 

 more than two-thirds of this total volume of saw 

 timber is in pines, over a quarter is in hardwoods, 

 and a small remainder in cypress. Approxi- 

 mately 40 percent of the volume of pines, hard- 

 woods, and cypress combined is in old-growth

 Scribner log rules and in lumber tally, 7931 1 



Volume Estimates 



THE volumes of sound wood are estimated in 

 three units of measure : Board feet, cords, and 

 cubic feet. The board-foot estimate includes 

 all the material that has the size and quality of saw 

 timber. The cordwood estimate includes the 

 board-foot volume converted to cords, including 

 bark, and in addition the material in trees under 

 sawlog size, in the tops of saw-timber trees, and the 

 sound material in cull trees, all of which additional 

 material is unsuited for saw timber but which is 

 convertible into such commodities as pulpwood, 

 fuel wood, fence posts, etc. The cubic -foot esti- 

 mate expresses the volume inside bark of all 

 material included in the cordwood estimate. 



Saw-Timber Volumes 



In estimating saw-timber volumes, only merchant- 

 able timber in live trees of commercial species was 

 included. All figures are net, deduction having 

 been made for loss due to turpentining and for both 

 woods and mill cull, i. e., portions of the tree which 

 are not suitable for Lumber on account of rot, 

 crook, firescars, bad knots, sweep, or other defects. 



Board-foot volumes by species groups are ex- 

 pressed in Doyle, Scribner, and International 

 %-inch rules in table 1 1 . The Doyle rule is given 

 because it is commonly used throughout Georgia 

 and the South, even though it underestimates the 

 lumber which may be cut from small logs and 

 overestimates the contents of large logs; only in 

 logs 25 to 35 inches in diameter does it closely 

 approximate lumber tally. The Scribner rule, 

 which is one of the official log rules of the Forest 

 Service, is more uniform than the Doyle rule, but 

 still underestimates lumber tally, particularly in the 



ree-species groups
