difference both in volume and in price between the above two 

 types of stems : — 



Stem A. 



A is a tree \2\ inches, quarter-girth measurement, grown in 



the open. 

 A is 72 feet high at 9 inches diameter, and is of the same age 



and grown in the same locahty as B. 

 A being over 12 inches on the side realises is. per cubic foot. 



Therefore A = ^^ — ii- x 72 = 75'03 cubic feet 

 144 



at IS. per cubic foot = j[^2)i ^S''- °1'^- 



Stem B. 

 B is a tree 10 ins., qr. -girth measurement, grown in close canopy. 

 B is 73 feet high at 9 inches diameter, age and conditions of 



growth being the same as in the case of A. 

 B being under 12 ins. on the side realises lod. per cub. foot. 



Therefore B = ^ ' x 73 = 507 cubic feet 

 144 



at lod. per cubic foot = j[^2, 2s. 3d. 



Thus it is seen that the stem of type A contains 24-33 cubic 



feet more timber than a stem of type B, and is worth ^\, 12s. g^d. 



more per tree than a tree of type B. The difference per acre in 



different woods of the two types would be infinitely greater. 



Offering for Sale. 



In connection with this, the question of conditions of sale 

 arises first. It is therefore necessary to specify where the timber 

 is offered, where the various lots are situated, the distance from 

 a good road, railway station and consuming centre. In addition 

 the species and number of trees are given together with their 

 dimensions, i.e. length and diameter at small end as well as 

 cubical contents. Further, all trees over 12 inches on the side 

 are classed and lotted as heavy timber ; trees over 8 and under 

 12 inches quarter-girth measurement as fnediian titnber ; trees 

 under 8 inches quarter-girth measurement as/// tvood. 



As a rule there are certain obligations incumbent upon the 

 timber merchant, for example, sites for sawing machinery for the 

 conversion of timber are chosen subject to the consent of the 

 grower. All operations require to be completed within a certain
