TIMBER-ASSORTMENTS. 239 



A billet of split firewood should measure from 5J 8 inches 

 (14 to 20 centimeters) along the chord of its smaller end, and 

 exceptionally up to 11 inches (28 centimeters); it should 

 always be split from the core of the tree.

Round firewood billets are unsplit round pieces of wood 2J 

 5J inches (7 14 centimeters) in diameter at the thin end. 

 In many districts, wood of this class is split in half. Round 

 pieces of larger dimensions are used sometimes in charcoal- 

 making. 



It is advisable always to split the round pieces of firewood in 

 order to ensure drying, reduce carriage and increase the heat- 

 ing power of the wood. Experiments have shown that round 

 firewood when split loses 27 28 per cent, more weight in the 

 five winter months than unsplit wood, and Schuberg has proved 

 experimentally that its loss in weight in four weeks' time is 

 double that of unsplit firewood. 



iii. Maw/)- and /fvof-tcwid. 



Pieces of stumps and roots of all sizes, provided they are not 

 longer than the other pieces of cordwood and may thus be 

 conveniently stacked, form this class of firewood. 



Faggot-wood includes all refuse crown, branch, and coppice- 

 wood under 2 J inches (6 centimeters) in diameter at the larger 

 end. 



This is either piled in heaps about equal in size, or tied 

 into bundles termed faggots, or bavins, which are of about 

 the same length and circumference as split cordwood 

 billets. The remaining refuse of the felling is collected in 

 heaps, and may be given away to the workmen, or auctioned. 



3. The Work of Conversion. 



The work of conversion comprises the woodcutter's work of 

 preparing the different assortments just described from the
