 of the wood from old trees, tin- diamrtrr- and heights of the tree* being 

 the same. 



In old field stands on dry soils tin- trees are of very rapid ^growth, 

 contain coarse knots, and most of them are dominant. < 1'lat.- III.) 

 For these reasons the yield of lower grades of lumber is also larger than 

 in the more crowded and usually somewhat slower growing stands on 

 forest soils. Eightv-tivr j>rr i-rnt "f tin- lumlx-r which is cut from stands 

 35 to 50 years old growing on the poorer old field site* is of box grade; 

 ten per cent, No. 3 ; and the balance, largely bark strips, cull, and No. 2. 

 This does not apply, however, to dense old field stands on moist sites.

The average tree being cut in the Norfolk district is about 14 inches 

 in diameter, Quality Site II, cutting to 7-inch breasthigh diameter. 

 Such a tree (in the present open stands) would be about 55 years old 

 and in first quarter 1913 would have had a stumpage value under an 

 operating cost of $14 per 1,000 board feet, of about $3.05 per 1,000 

 board feet mill cut or allowing for over run of 30 per cent above log 

 scale, a stumpage value of $3.85 based on the Doyle-Scribner scale, which 

 was close to the general price for average sturapage in the Norfolk dis- 

 trict in the latter part of 1912 and first half of 1913. 



*Air dried circular-sawed lumber would be about $1.00 per 1,000 board feet lower. 

 tJuly 1914 prices are about $1.50 per 1,000 board feet lower.
