during the period of 40 — 50 are assumed to have been made 

 in the year 50. 



This table shows that the linaneial rotation fahs between 

 the years 70 and 90. In order to ascertain the exact year, the 

 rentals given in cohimn h of the table have been plotted (see 

 Fig. 44). It will be seen, that the financial rotation falls 

 into the year 79, when the rental reaches its maximum. 



In column / the current annual forest per cent, is given, 

 calculated according to the formula on page 192. These data 

 show, that the forest- or indicating per cent, passes from 

 above 2i per cent, to below "Ih per cent, between the years 75 

 and 85. By plotting the per cents, (see Fig. 45), it is found, 

 that the exact time falls into the year 79, that is to say, the 

 year, when the annual soil rental culminates. Hence the 

 wood was financially ripe in the year 79.
