Several kinds of wood are sold by special measures. Teak is sold by the 

 load of 50 cubic feet. Wainscot Oak logs, although they have three square 

 sides and one roimd, are sold by calliper measure, which entails a loss to 

 the buyer on conversion. Hewn Oak logs from Odessa and Libau, although 

 eight-sided, are also invariably sold by calliper measure. Birch logs, on the 

 other hand, are sold by string measure— ^'.e., actual girth-~-although the 

 price is based on their calliper depth. 



Sawn Pitch-Pine logs are sold in some ports by string measure, and in others 

 by calliper— the former giving an advantage of 5 per cent, to the buyer. Pine 

 and Spruce deals are sold by the St. Petersburg standard, which contains 



165 cubic feet. 



Mahogany, and Mahogany alone, is sold by what is called Brokers' measure, 

 a custom dating from the time when it was usual to allow a hand's-breadth in 

 ^very yard to the buyer to compensate him for loss in conversion. A " broker's 

 rule " is 13^ inches to the foot, and this broker's measure gives the buyer an 

 advantage of from 25 to 40 per cent, over the calliper measure, or extreme 



contents of a log.
