the plan; it merely means that, for example, instead of felling 

 every year one compact area of 500 acres, we are going to fell 

 every year five different areas of 100 acres, each located in a 

 different part of the forest. Each felling-series will be a complete 

 and self-contained miniature of the whole working-circle, and 

 should contain therefore as nearly as possible an equal area of 

 every age-class. The number of series determined on will fix 

 the size of the annual felling area in each series, and this number 

 will be chosen, after due consideration of the questions above 

 indicated, namely protection against wind or insects, distribution 

 of produce in different directions, export and supervision, so as 

 to produce manageable coupes of the most convenient size.
