THE THEORY AND PRACTICE OF WORKING PLANS 197 



ing period, there are, in Saxony, intermediate revisions in the 

 middle of the working period. The most important features of 

 revision are the entry of cuttings and plantings on the map of 

 the forest; the comparison of the actual cut with the estimate; 

 the necessitated departures from the prescriptions of the work- 

 ing plan. 



For purposes of forest organization the usual stand map 

 (scale of I : 20,000 or i : 15,000) showing species, age classes, 

 and cutting series, is used as a base whereon to show the intended 

 cutting areas of the next decade, special planting areas, the 

 cutting series, etc. 



IV. WURTTEMBERG 



Wiirttemberg and Baden between them contain the Black 

 Forest, that long line of low ranges flanking the Rhine on the 

 east. Wiirttemberg has an area of 4,819,958 acres, of which 

 30.77 per cent or 1,483,025 acres are forested. 



Wiirttemberg is traversed by various low ranges which 

 give to the whole kingdom a rolling topography. The species 

 corresponding thereto are preponderatingly spruce and fir. 



The splendid development of the timber market in Wiirt- 

 temberg and of the road system necessary to get the timber on 

 the market puts Wiirttemberg on a par with Saxony as regards 

 financially profitable management. 



Wiirttemberg 's systematic forest organization dates from 

 the year 1878. The experience gained during the years follow- 

 ing led to a sweeping revision in 1898. Since then there has 

 been a second, tentative, revision of the working plans instruc- 

 tions in 191 1.* The period method has been dropped, with the 

 impractical endowment of areas in advance for each twenty- 

 year period of the rotation. Attention has been centred on the 

 segregation of stand units, i.e., subcompartments and the 

 regulation of cut based thereon rather than on the area of arbi- 

 trary divisions (compartments). The condition of the individual
