The table above is for the average outside-bark form class for all trees sampled. Factors for 

 determining volumes for trees in other form classes (both outside-bark and inside-bark) are given 

 in Buell (1942. 



^Volume as utilized to a variable top diameter. 



^Basic data: 150 trees from Cherokee, Pisgah, and Nantahala Forests; Jackson County, Ohio; 

 and Bland County, Va. 



Table 27-29 — Gross volume of chestnut oak trees, Scribner log scale (Schnur 



1937)i-2-3 



'Scaled in 16-foot log lengths with trimming allowance of 0.3 foot; additional top sections 

 scaled as fractions of a 16-foot, 8.0-inch log. Stump height 1.0 foot. 

 ^Heavy lines indicate limits of basic data. 

 ^Trees measured were in Connecticut, Maryland, New York, Ohio, and Pennsylvania.
