114 Forestry Quarterly 



From 1826 to 1876 a change in method, introducing thinnings, 

 was substituted. But in 1876, a sheltenvood method was intro- 

 duced. The rotation was increased for some parts to 150 years in 

 six periods of twenty-five; later in 1905, a rotation of 180 years 

 in six periods of thirty was adopted for some parts. The felling 

 area comprises now about 2,200 acres, the timber being partly 

 sold en bloc, partly by measurement. The total cut amounts to 

 62 cubic feet per acre. The prices obtained range as follows: 

 oak 14 cents and beech 10 cents per cubic foot of workwood; 

 split cordwood about $2.30 per cord; branchwood, $1.25; and 

 charcoal wood 35 cents. 



The gross income was $4 per acre, the net $3.44 or 5.5 cents per 

 cubic foot. This to the Swiss forester appears very small compared 

 with similar sites in Switzerland, where a similar forest cited 

 produces with 70 cubic feet per acre, a net result of $6.30, or 9 

 cents per cubic foot. 



The change to oak forest is recommended or else planting in of fir, 

 which succeeds excellently in the mild climate of the locality, in 

 100-120-year rotation, when 70 to 80 per cent, workwood and a 

 net yield of over $8 might be expected.

UTILIZATION, MARKET AND TECHNOLOGY 



In the Spring of 1913 the Forest Service 



Deterioration of made an investigation of the deterioration 



Blight-killed of blight-killed chestnut timber. The age 



Chestnut of the trunk sprouts was taken as the number 



of years since the death of the tree, since, 



in most cases, such sprouts do not appear before the tree dies. 



It was found that the sapwood is honeycombed with insect 

 burrows in three years after death, rotted in four years, and begins 

 to dry and peel off in the fifth year. The bark falls off the trunk 

 during the fourth and fifth years, and checking does the most 

 serious damage during the fifth and sixth years and probably later. 

 The heart is sound at the sixth year, except for heart rot or insect 

 injury, which in many cases noted, seemed to have preceded the 

 blight.
