range within relatively small areas and where the evenaged 

 stand is lacking in uniformity, there the regular arrangement 

 of cutting areas necessary under the strip method is imprac- 

 ticable. 



The patch or group method, which is in reality merely an 

 irregular strip method, can be employed instead.
