i26 FOREST REGULATION 



Cutting Series of two lots each .'. 125, of 160 acres each. 



Yearly cut (by area) : 250 acres. 



Cut during one "period" or 20 years: 5000 acres or about 31 

 Cutting vSeries. 



Cutting area 40 acres, with 5-year rest between cuts at any one 

 place. 



Having over thirty different Cutting Series or independent 

 parts, all of them with ripe or sufficiently ripe timber, ready to cut, 

 the forester has ample choice, he can cut at thirty different points, 

 and if at any one point reproduction is not succeeding, if insects are 

 destroying his plantations in any place, and it is necessary to wait, he 

 is in position to do so. In short this division into Cutting Series 

 gives many points of attack, it makes the entire enterprise "flexible", 

 enables the forester to cut any stand when it is necessary, without 

 hurting the rest of the timber, and enables him to give each stand 

 the care it needs. 



In our beginnings in the United States it may seem too early to 

 speak of such refinement of methods as the Cutting Series indicates. 

 But it is almost certain that the next fifty years will demonstrate the 

 dangers and losses which are sure to come with extensive unbroken 

 areas of pure growing stands of pine, etc. The Cutting Series is a 

 silvicultnral;. necessity, and its development is neither difficult nor 

 costly. 



14. It is evident, from the foregoing that the Cutting Series is 

 not always a permanent division right from the start, but, like the 

 Sub-Lot, or stand division, it may for many years be in a temporary 

 condition of development. As to its size, the present tendency is 

 toward making each Lot a Cutting Series and getting the greatest 

 possible use out of the system of lines maintained, as well as the 

 smallest possible Cutting Series.* 



15. Working Section. German: "Betriebs Klasse". Where 

 a forest property is of ordinary size, (25000 acres or less) and is 

 made up of one type of timber, all pine, all mixed hardwoods, etc. 

 Regulation of the cut usually applies to the entire property.

 of this silvicultural division of the forest.
