and also records the number of chains measured. 



When the other end of the woodlot is reached, the note- 

 keeper sets the compass and turns it until it reads the original 

 bearing. Two or three chains more are measured ahead where the 

 compass is again set and turned at right angles into the woods 

 (180 degrees to the first turn). Then one chain after another 

 is measured ahead and the d.b.h. of the trees recorded until the 

 other end of the woodlot is reached. 



This process is repeated until all the trees above 6" on 

 the strips have been measured. A strip 10 chains long and 1 

 chain wide is equivalent to an acre; therefore, if a stand has 

 5 strips, each strip being 5 chains long and one strip for every 

 two chains, the total area of the stand would be 5 acres. 



2) The Broad-Strip Method: 



This method is practically the same as the narrow strip 

 method except that, instead of measuring one strip in every two 

 or three chains, four or five chains are taken. 



3) Circular Quarter-Acre Method: 



Select any section which is representative of the stand, 

 and with the note-keeper standing in the centre, the caliper -men 

 measures evexj tree above 6" within a radius of 59 feet. The 

 number of these sample plots required depends upon the size and 

 regularity of the stand. In estimating the Meads and Slim Jim 

 Woodlots, three sample plots were taken on each plot, and by 

 averaging the volume of the timber found on these circular plots, 

 an average volume for the plot ( one-fourth of an acre) is ob- 

 tained. 



4) Tree-to-tree-count Method:
