. Impressions of European forestry : letters written during a six months' visit to England and to the continent . Forests and forestry. and reboisement occupy a large share of the attention of the foresters. An interesting ex- ample of the necessity of building barrages and side walls even on the portion of a tor- rential stream where the gradient has become relatively gentle, is to be seen just outside of Interlaken, where before the correction work was undertaken much damage resulted in time of flood to valuable meadow land, of which Switzerland has at best all too little. As the methods followed in the two countries are essentially alike, it may not be inappro- priate, for the purpose of this letter, to in- clude Swiss examples, even when discussing French forest methods. Where there are flats or depressions at or above the tops of the steep slopes, as is often the case in the section of the Alpine high pas- tures, there is some tendency for the land to become boggy. Here artificial drainage is often practiced, by the construction of ditches Conservation des Terrains en Montagne" Paris, 1911. In recent years, as has been said, more and more attention has been given to attempting to prevent the trouble at its source, through the afforestation of the upper parts of the catchment areas by establishing forest plan- tations. A lively discussion between the en- gineers and the foresters continued for a long time over the relative merits of the two methods of approaching this problem. One can hear today more than echoes of it. But the results that have followed the afforesta- tion of certain watersheds seem now to have swung the balance distinctly to the forester's side of the argument. Nevertheless the dams and other engineering works will always have their place on certain streams. The species used in these high mountain plantations naturally vary with localities, de- pending on the elevation, aspect, soil and ex- CREST OF THE LITTORAL DUNE AT MIMIZAN, LANDES, FR
