GERMAN FOREST MANAGEMENT—SILVICULTURE. 247 comprised in the one name, "forest economies/' are incidental, and may differ even in principle in various countries and conditions, the methods of crop production or forest culture, being based on the natural laws of the interrelations of plants to soil and climate, must, at least in principle, be alike all over the world. Here pure forestry science linds its application and development. These principles have been elucidated more fully in the next chapter. We will, therefore, here only briefly restate the more important ones with some of their applications in German practice. PLANTING. Seemingly the simplest and easiest way of reproducing the crop is that practiced in agricul- ture, namely, removing the entire mature crop and sowing or planting a new crop. But this method, which has been so largely practiced in Europe and admired by our countrymen and writers on forestry, has its great drawbacks, which have of late become more and more apparent, and the tendency now is to return more and more to the u natural ; While the simplicity of the method of clearing and planting recommends itself for a routine or stereotype management, it has not always ptoved as successful as would be expected. The large clearings which the young planted seedlings are unable to protect from the drying influences of sun and.

And when it is understood that to secure a desirable stand the plantings must be gone over and fail places replanted five, six, and more times, it becomes apparent that the method is extremely expensive, and hen
