TABLE No. 7. Graded Mill Tally Log Rule for Beech 

 Concluded. 



16-Foot Logs. 



While they can be applied with substantial accuracy only to conditions similar 

 to those under which they were made, these tables may perhaps be used in other 

 regions by carefully studying and comparing defects, methods of utilization, etc., 

 and applying suitable converting factors. With these precautions graded volume 

 tables can be constructed by combining the graded log rules here given with 

 tables which show the average taper of trees. Graded volume tables actually 

 constructed from these tables will be found on pages 37 to 47. They are not 

 based upon taper tables but on felled trees (yellow birch, 505; sugar maple, 301; 

 beech, 220).
