while the stands were estimated to belong between the second and 

 third site classes chemical analj^sis showed it was poorer than the 

 fifth class. This, the authors take, indicates the need of a re- 

 vision of the classification of soil values as based on chemical an- 

 alysis, at least for the region under discussion.

For a brief account of the most modern 

 Reboisement methods and cost of reboisement work in 



in Alpine regions, to prevent torrents, soil 



Switzerland. washes, land and snow slides, the account 



of a journey of a number of Swiss foresters 

 is useful. This journey was an official one, arranged by the De- 

 partment of Interior for the instruction of the participants. Of 

 new ideas we note the substitution of a system of man}' dams in 

 series, each subsequent one with its crest 1.5 m above the foot of 

 the preceding, instead of a rubble bed at the foot of each dam, 

 these latter more widely apart. In this way small, quiet ponds 

 are formed between the dams, while the rubble beds were liable 

 to be destro^^ed by the rushing water. 



Gentle slopes of dams are more liable to damage than 

 steeper ones. Drainage by covered (filled with rock and brush), 

 deep (4-5m) ditches is effective in preventing land slides. Iron 

 posts for fastening barriers to hold back debris are used where 

 hard subsoil prevents use of wooden posts. The planting of alder 

 I to 2 feet apart is often more effective and cheaper than basket 

 work. The excellent result of its use is discussed at length in 

 Schweizerische Zeitschrift fiir Forstwesen 1906 p. 19-22. 



The use of sod to cover walls, where large stone flags are not at 

 hand, protects the walls against weathering. Terracing, where 

 good material for walls is lacking, appears more effective. 



A perfectly successful prevention of snow slides has been effected 

 at the foot of Muot, protecting the Rhatish Railroad (described in 

 detail in S.F. Sept-Oct. 1904). Greatest activity in re-foresting 

 is found at Pontresina on the Schafberg, where sheep had de- 

 stroyed all vegetation. The planting with spruce, larch and pine 

 has been done at a cost of $11 per M., everything included. In 

 a neighboring district this cost was reduced to $7.65. Planta-
