UTILIZATION STANDARDS 



The practice of forestry not only requires the harvesting of suc- 

 cessive crops of forest products, but implies the most complete 

 utilization practicable so as to secure the maximum amount of usable 

 material from each tree cut. As the price of lumber goes up and as 

 logging and sawmill machinery are improved, utilization becomes 

 more and more complete. There is still plenty of room for improve- 

 ment, as now not more than 35 per cent of the tree as it stands in 

 the forest is utilized. The principal waste is in slabs, tops, sawdust, 

 branches, stumps, and in the custom of using logs of only even 

 lengths, and in trimming, and edging the boards. 



The Forest Service requires that on the National forests stumps 

 be cut low, not over 12 inches on the uphill side for poles, ties, and 

 other material up to 12 inches in diameter, and not over 16 inches

high for larger trees. It also requires that the log lengths be 

 arranged to utilize the whole trunk of the tree down to a diameter 

 of 7 inches inside the bark. Private operators are gradually im- 

 proving their utilization in both the logging and the manufacturing 

 ends of the business, and it may be expected that waste will be re- 

 duced as fast as economic conditions permit. 



BRUSH DISPOSAL 



One of the most difficult problems in the handling of timberlands 

 for the production of repeated crops is the proper disposal of the 

 slash, brush, or refuse left after logging. This is important both 

 because of the direct effect upon reproduction and erosion, and 

 because <>f the tremendous influence slash disposal has in protecting 

 the cut-over area from fire.
