It is 11 ^ootl plan to dig a canal from the floating-channel, 

 which reunites with it lower down stream. The land between 

 the two watercourses will then 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 



River-depot at Tlialliam. 



point Avhere the canal reunites with tlu' main stream. If the 

 terminal boom is on a small weir, and sluice-gates are sui)plied 

 to the lateral boom, the wood can be stranded almost dry in the 

 bed of the canal. Fig. '2;"5G aflbrds an example of this system in 

 the river depot at Berchtesgaden. The floating-channel {a) from 

 the Konigsee here joins the river Eamsau (h) ; canals and depots 

 are provided for the wood from the Konigsee at (c) and (m), and 

 at {<■'} and (iii') for the wood from the Ramsau, whilst the 

 terminal booms are at {!>) and (//). The canals are paved with 

 stone, and the wood is stranded almost dry. 



Side-canals often bifurcate from floatin<f-channels and lead to all
