APPENDIX 



After the map is drawn and closed the area must be found. 

 Using one side of the woodlot or map as a base, as shown in 

 the diagram, mark it off in inches, carrying the line out if 

 necessary beyond the map. At each inch mark erect lines 

 perpendicular to the base line. Then divide these lines off 

 into inches from the base line and draw lines through them 

 parallel to the base line, thus dividing the entire map into 

 square inches. 



Each square inch represents an area lOO feet by loo feet 



and contains 10,000 square feet. In the diagram there are g 

 complete square inches, making 90,000 square feet. The areas 

 of the imperfect squares must now be found. Divide each of 

 these squares into quarters as shown, each of which will be 

 50 feet by 50 feet, containing 2500 square feet. Cross off 

 every perfect quarter inch square. There are 10 of these in 

 the diagram, making 25,000 square feet. Now divide each 

 imperfect quarter inch square into quarters. These will be 

 25 feet by 25 feet each containing 625 square feet. In the 

 diagram there are 25 of these perfect, making 16,875 square 

 feet. The imperfect squares remaining around the edges of the
