432 WOOD-DEPOTS. 



It is a good plan to dig a canal from the floating-channel, 

 which reunites with it lower down the stream. The land 

 between the two watercourses will form a good depot. At the 

 point where the canal leaves the floating-channel, the latter is 

 barred by a lateral boom, the terminal boom being placed at 

 the point where the canal reunites with the main stream. If 

 the terminal boom is on a small weir, and sluice-gates are

supplied to the lateral boom, the wood can be stranded almost 

 dry in the bed of the canal. Fig. 281 affords an example 

 of this system in the river-depot at Berchtesgaden. The 

 floating-channel (a) from the Konigsee here joins the river 

 Ram sau (b) ; canals and depots are provided for the wood from 

 the Konigsee at c and ra, and at c and m- for the wood from 

 the Eamsau, whilst the terminal booms are at b and b'. The 

 canals are paved with stone, and the wood is stranded almost 

 dry. 



Side-canals often bifurcate from floating-channels and lead 

 to all parts of the depot, they again unite into mam canals,
