14. — Selective cutting in northern hardwood— hemlock saic- 

 timber stands of the Goodman Lumber Co., Goodman, 

 Wis.: A, Area after selective cutting. Only mature and 

 badly defective trees were removed. A cutting of 51 

 percent of the volume brought 71 percent of the present 

 merchantable value, leaving the tract in condition for 

 continuous production. B, Light selective cutting in 

 advanced second growth. Only the largest "pay" trees, 

 comprising about 50 percent of the volume, were re- 

 moved. Insofar as practicable, logging was confined to 

 old-growth stands producing little or no net growth. C, 

 Selectively cut spruce-cedar sivamp. Approximately 50 

 percent of the merchantable volume teas removed. 



15. — Selectively cut hardwood stand on lands of the Pat- 

 ten Timber Co., Amasa, Mich. This company has been 

 practicing selective cutting for about 10 years. About 

 30 percent of the volume in the smaller-sized trees was 

 left in the residual stand for future growth. f-soosis

 9,000 board feet per acre. About 30 percent of the mer- 

 chantable volume is being left after the first cut. The 

 residual stand puts on a net groivth of about 160 board 

 feet per acre a year. A, A virgin harduood timber stand: 

 B, Stand after selective cutting.

20. — Strip cutting in a mature, even-age, pure black spruce 

 stand in Minnesota. In order to reduce the fire hazard, 

 assure adequate restockitig by seeding from the side, and 

 to prevent excessive wind damage, often in such stands 

 it is most practical to clear-cut in narrow strips. ^309393
