A COMPARISON OP MKTHODS OP 



TIM3KE liSTILI^TE^G 



Methods applied: 



Two woodlots, the "Slim Jim" and "Meads", have been es- 

 timated during the course of study, and four methods were used 

 on each plot. They are: 



1) Narrow Strip Method: 



The instruments used in this method are one pair of 

 calipers, one staff compass, one 66-foot chain and a note-book 

 to tabulate the results. Two men form a working crew. The 

 compass is first set at the corner of the woodlot and the direc- 

 tion obtained by loosening thig "bo^^ss screw and reading the 

 bearing. Following the direction, the crew measures two or 

 three chains ahead, the number depending upon the regularity of 

 the stand. In a more regular and even-aged stand, as in Meads 

 Woodlot, one strip for every three chains is measured while in 

 an irregular and uneven-aged stand such as the Slim Jim, one 

 strip for every two chains is necessary. After the crew has 

 measured two chains parallel to the edge of the woodlot, the 

 compass is set and turned at right angles to the original bear- 

 ing into the woods. One chain is measured ahead, the caliper- 

 man holding the head end of the chain and the note-keeper the 

 rear end. The latter also attends to the setting and reading 

 of the compass bearing. The caliper -man then measures the d.b.h. 

 of every tree above 6" thirty-three feet on either side of the 

 chain. The note-keeper tabulates the results by tl^e 'B.ot-system"
