TIMBER AND TIMBER TREES. [CHAP. 



lengths of the tree are slightly hewn upon two opposite 

 sides, and then sawn down the middle; the logs have 



thus a nearly semicir- 

 cular form (Fig. 22), the 

 average contents of each 

 being only about 16 feet 

 cube. This timber de- 

 rives its chief value from 

 the figured appearance 

 it presents when cut, or 

 converted in the direc- 

 tion of its medullary rays 

 into boards or veneers for cabinet purposes. 



Riga wainscot timber passes through the process of 

 bracking prior to its being shipped, and dealers have 

 the option of making their selection from either the 

 Riga, English, or Dutch crown qualities or the brack 

 quality at prices varying with the market rates. These 

 stood recently at about 100, 90, 80, and 60 shillings 

 respectively for the log of 18 feet cube, a peculiarity in 

 the mode of selling, which is exclusively confined to this 

 description of timber.
