WOOD-DEPOTS.

Fig. 293. This excellent mode of stacking keeps the wood dry 



without any considerable cost. Wherever, in high stacking, 



the stack has become higher 

 than a man's chest, stands must 

 be used from which the billets 

 may be handed to the stacker. 

 This is especially the case with 

 roofing. Evidently the billets 

 should be piled as densely as 

 possible, and the walls of the 

 stacks made vertical. 



Many wood-depots in towns 

 are intended to facilitate the 

 sale of wood to small pur- 

 chasers. In such cases the 

 wood must be supplied in 

 ordinary sale-lots. The stacks 



are then usually twice as high as the billets are long, and are 



separated by upright posts. In other depots the wood is 



measured separately for each 



purchaser. Whenever the 



sale of firewood is carried on 



in detail, it should also be 



sorted according to quality; 



this assortment of the wood 



is effected as soon as the 



wood is landed, the various 



pieces being brought together 



from all parts of the depot. 



When once the wood has been 



sorted and stacked, the stacks 



are numbered and measured. 

 Wherever firewood is piled 



in mixed stacks without 



separation into sale-lots, the

measuring is done simply by 



taking the length and height of each stack ; where the billets 

 are crossed, a deduction must be made from the volume, the 

 amount of this deduction being ascertained by experiment and
