the wood as much as possible from the ground and prevent 

 its deterioration ; or merely two parallel lines of billets are 

 laid on the ground, on which the wood is stacked. In the 

 clamper parts of wood-depots, especially in the case of large 

 depots where there is not enough fall to allow the water to 

 drain-off rapidly from the wood, and wherever the wood is 

 stacked whilst still wet, 

 this should be done as 

 in Fig. 292. 



Each stack must be 

 finished off at both ends 

 by crossing the billets to 

 prevent it from falling. 

 In very long stacks, it 

 is advisable to place 

 some rows of crossed billets in their centre, so as to give more 

 stability to the structure. In the case of very high stacks, 

 the crossed billets at their ends should be connected by trans- 

 verse pieces, as in Fig. 298. Between any two stacks there 

 should be left a space of at least two feet, to allow for 

 ventilation. Wherever, on account of scarcity of space, it is 



necessary to reduce 

 the distance between 

 the stacks to two feet, 

 and the stacks are 

 also high, two adjoin- 

 ing stacks are joined 

 as shown in Fig. 298, 

 which greatly adds to 

 their stability. Wher- 

 ever carts must pass 

 between the stacks to remove the wood, a sufficient passage 

 must be allowed between adjacent stacks for their passage. 

 Not unfrequently, however, owing to want of space, four to 

 six stacks are crowded together without any intervening space, 

 as, for instance, at Prague, where the arrangement shown in 

 Fig. 294 is followed. 



Where large quantities of firewood remain stored for a long 

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