FOEESTRY WORK 



necessary to take the measurements from the area 

 itself. 



The above plan represents a piece of ground with three 

 straight sides and a curved one. 



When there are no trees to obstruct the view, the 

 measuring is done on the actual area, but when the ground 

 is fully stocked with trees this is impossible. The area 

 then must be measured from the outside. I will first 

 try to show how the area is measured from the inside, 

 and later by the other method 



In measuring land, it is not wise to trust to the 

 possibility of any two sides being parallel, or any 

 angle being a right angle. It is best to make one's 

 own right angles. Base hnes must first be poled off and 

 measured.
