The same instruction applies to a second or third rot column, if encountered. For 

 example, suppose that a single rot column extends from the stump upward into the tree 

 bole. Designate cross sectional areas of this rot column as the First Cull Area. UTien 

 a second rot column is encountered, as shown in figure 5, its measurements will be 

 recorded under Second Cull Area. The same would be done for a third rot column. IVhen 

 the first rot column runs out, do not shift columns on the data sheet. Data for a 

 continuous rot column in the tree must be recorded entirely under one cull area column. 

 Continue to record measurements of the second rot column under Second Cull Area until 

 it runs out. Do likewise for the third rot column. If more than three rot columns are 

 found in a tree, the fourth or fifth rot column may be recorded in a set of columns that 

 has been used previously, provided that at least one row for measurements that is blank 

 in these columns separates the measurements of the two rot columns. Or, if any cross 

 section of the tree bole has more than three cull areas, group the measurements in such 

 a way as to result in recording measurements for three cull areas, one or two of which 

 are actually composed of t\-JO separate cull areas. 



All measurements recorded on the data sheet should be in feet and tenths and hun- 

 dredths of feet. Faint vertical lines ruled in the columns would help to guide the 

 placement of digits. To promote accuracy in keypunching, it is essential that digits 

 be placed properly. 



Although the heights at which the tree will be cut are already written into the 

 columns headed Height Above Ground , every alternate row has been left blank so that an 

 intermediate cut resulting in 4-foot sections could have measurements recorded. If cuts 

 are taken at irregular heights, record them on the alternate rows and strike out the 

 height figures that are printed on the other lines. At the top of the tree, record 

 total tree height on an alternate line (unless by chance tree height is identical with 

 one of the heights printed on the form) , and record 000 under 1 and 2 for both DOB 

 and DIB.
