10 PRELIMIXARV MEASUREMENTS 



D. Method of Procedure. 



1. The chief of party should systematize the work as soon as i)ossil)Ic, 



for not until each man knows exactly what to do, and follows the 

 same routine for each tree, will the work progress rapidly and 

 efficiently. 



2. The following method of procedure has been found efficient in Pacific 



Coast timber: 



The Poleman. 



(a) The poleman first approaches the stump of a tree, marks it 

 with the crayon to prevent repetition, and then, setting the 

 8-foot pole alongside it, obtains its height. Care must be 

 used not to measure the longest nor the shortest height, but 

 the average. The poleman then calls out the measurement to 

 the notekeeper and before proceeding further waits for him 

 to repeat the figure to avoid errors in tallying. 



(6) Keeping his thumb on the pole at the point which indicates the 

 height of the stump, he lays the pole along the first log with 

 his thumb against the saw cut. The breast high point on the 

 pole now shows where the D.B.H. measurement should be 

 taken. This point is kept until the caliperman takes the 

 D.B.H. or it is indicated by an axe or crayon mark. 



(c) Starting from the saw-cut at the butt of the first log the poleman 

 now proceeds along the bole (up the tree) measuring the 

 lengths of all sections, including the tip, and the clear length, 

 in feet and tenths. The length of the tip should be carefully 

 measured to the terminal bud, and if broken, a little time and 

 care should be used to find the missing pieces. If they cannot 

 be found, however, the length actually found should be 

 measured and recorded as "found top"; and the missing part 

 should then be estimated, and recorded as "estimated top" 

 on the tally sheet (analysis sheet.) The clear length, which is 

 the length from the large end of the butt log to the first 

 prominent green limb, should be measured as the poleman 

 proceeds up the bole. 



The Caliperman. 



(a) The caliperman follows close behind the poleman, measures and 

 calls out to the notekeeper the various diameters and thickness 

 of bark measurements as they are obtained in order. First, 

 he obtains the D.B.H. at the point indicated by the poleman. 

 This, since it is the most important of all measurements, 

 should be obtained with great care by taking the longest and 

 shortest diameters, or, when this is obviously impractical, 

 by two measurements at right angles.
