were reproduced in the figures 1, 2, 3 and 4. The area of every section 
and of every square were measured with a planimeter. l'inally a ground 
description was prepared containing informations about section- and 
square-number, area, character of land, soil type, degree of stone blocks, 
tree species, moisture, forest site and appraisal. After that it was poss- 
ible to compare the corresponding squares, and the sections within 
them, in respect to geometrical position and area etc.
