the line from a long way off. For reasons of easy 

 inspection, therefore, as well as for reasons of economy 

 in demarcation, boundary lines should be made as 

 straight as practicable, with as few angles as possible. 

 An irregular boundary, with many projecting and re- 

 entering angles, is not only much more expensive in 

 itself per unit of area that it protects, but is made still 

 more so by the number of boundary pillars which have 

 to be erected at the angles. If, therefore, a forest with 

 irregular boundaries has to be demarcated, it is to the 

 interest of the owner of the forest to negotiate with the

adjacent owners for an exchange of his land with some 

 of theirs in order to rectify his boundaries, and it may 

 pay him well to give in exchange a considerably larger 

 area than that which he receives in exchange. Fig. 84 

 shows at a glance how, without materially affecting the 

 area, the irregular boundaries of a piece of forest can be 

 straightened along the lines AB, BC, CD, and DA, thus 

 effecting a saving in the length of lines to be cut, the 

 number of boundary pillars to be erected, and in subse- 

 quent cost of upkeep. 



In places where, notwithstanding careful clearing, 

 boundary lines are apt to get thickly overgrown during 

 a year, it will probably be cheaper, and certainly more 

 advantageous, to replace the cleared line by a ditch,
