The stacks are then usually 



time at a depot, a roofing of billets is often supplied, as in 



fig. 263. 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. 



The billets should evidently 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 purchasers. 



In such cases the wood must be 



supplied in ordinary sale-lots.

upright posts. In other 



depots the wood is separately ^^'^' '^^^'

 Whenever the sale of firewood

 should also be sorted accord-

 of the depot. When once the 

 wood has been sorted and

Wherever firewood is piled 

 in mixed stacks without sepa-

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

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