FORESTRY AND TIMBER 



Allowances for taper in logs 



This table is intended to be used simply as a guide. The allowances for taper 

 should be varied to conform to the actual taper 



Cubic Log Measure (The Woodsman's Handbook) 



A cubic unit, either the cubic foot or cubic meter, ultimately will be 

 in common use for the commercial measurement of timber. This will 

 come about with the increase of the value of timber. When the whole 

 log, including slabs, can be used, the owner cannot afford to sell his 

 logs purely on a basis of an estimated product in manufactured boards. 

 If logs are bought according to their solid contents, though they may 

 not cost more, yet the buyer will feel that he pays for the material he 

 wastes, and therefore will be more eager to utilize it. 



There are a number of methods of determining the solid contents of 

 logs in cubic feet. The two methods in most common use for commer- 

 cial work are given in this book. Other methods, designed for scientific 

 work, are discussed at length in treatises on forest mensuration.
