134 THE PRINCIPLES OF HANDLING WOODLANDS 



of strips established in each. Suppose, for example, 

 that a tract 900 feet long, such as that represented in 

 Fig. 29, is to be cut, and it is desired to remove the 

 timber in 12 years. Suppose, further, that reproduction 

 of the cleared strips can be secured in about 4 years. 

 The aim should then be to cut over a single division 

 in three operations indicated in the figure as I, II and 

 III. The first cutting then removes 3 strips, each 100 

 feet wide, separated by a distance of 200 feet. After 

 about 4 years, the second operation removes the second 

 strips bordering on the first. At the end of the next 

 period of 4 years, the final strips are ready for repro- 

 duction. This last strip cannot be cut clear and 

 reproduced naturally, for there would be no seed-trees 

 left standing. It is, therefore, either reproduced nat- 

 urally by some other system, or cut clear and restocked 

 artificially. 



Use in this Country. This system is not used very 

 commonly, even in Europe. It has not been used in 

 this country in a systematic way, as far as the author is 

 informed. It is probable that it will occasionally be used 

 in a small way in cutting woodlots under certain condi- 

 tions. Thus, it is sometimes customary to cut off the 

 even-aged stands of white cedar in New Jersey by strips. 

 "The owner cuts a strip each year and gradually works 

 over the swamp. He does not cut in this way in order 

 to secure reproduction, but because it is the most con- 

 venient way for him to operate. The result, however, is 

 a series of strip reproduction cuttings. Probably the
