STAXD OF MARITIJME I'IXE NEAR , FRANCE, SHOWING TURPENTINE FACES THAT HAVE BEEN WORKED FOR YEARS there wiil be a material reduction in tlie quantity of water that has to be controlled in the torrent beds, and with increasing vol- ume, the torrents grow in power. Necessarily forests that are formed by such afforestation are essentially of the "protection forest" type, and are not to be considered from the viewpoint of commercial utilization for timber. But that they serve an important economic end and are of value to the nation is a fact that is absolutely self evident.

Anyone who has seen how rapidlj' erosion goes on in that section of the United States, once the cov- er of vegetation has been removed, is not in- clined to question the wisdom of the legisla- tion that was then enacted, or of that which has followed since in providing additional ap- propriations. But there are other sections of the country where similar provisions might well be put in force.

Of the many lessons Americans can learn from European forest history that of the control of torrential streams is not the least.
