METHOD OF LANDING AND STORING.

depot at Lana, near Meran is given (Fig. 288). The stream 

 K coming out of a rocky valley R R brings the wood between 

 the strong river- walls a, a and the long boom m, m by the 

 floating-channel </, d into the depot z, where the wood is 

 stacked at M. The waste-water flows back into the river. 



In all mountain-streams where floods occur, sawmills, as 

 well as wood-depots, are placed in side-channels. This is 

 essential, so that each mill may obtain its water-power 

 separately and leave the main stream free for other mills and 

 for floating purposes. In Fig. 290, the stream A is closed by 

 a long lateral boom (w) at the outlet of the mill-steam B. A

(n) is a second boom with a removable grating, behind which 

 are sluice-gates, so that both the water and the floating wood 

 may be under control ; (a, a, a . . .) are outlets. The saw- 

 mills (k, k) receive the butts directly by water ; the sawn 

 boards are bound into rafts below the mills and rafted down- 

 stream. 



(b) Method of Landing and Storing Floated Wood. As 

 soon 'as the wood has been collected in front of a boom, the 

 measures taken for landing it must be arranged so that it may 

 be brought out of the water as soon as possible. Whenever 

 the depots are arranged so that the wood becomes stranded 

 of itself (p. 433), the workmen must be stationed at the
