WOOD AND FOREST. 



Two-storied Seed Forest. A modification of the system of Kegu- 

 lar Seed Forest is the planting of another and a tolerant species of 

 tree under older intolerant trees to make a cover for the soil, to 

 prevent the growth of grass and weeds, and to improve the quality of 

 the upper growth. 2

mon, that the usual way of reproducing forests is to plant trees. It is 

 true that in the pineries of North Germany and in the spruce forests 

 of Saxony, it is common to cut clean and then replant, but it is ab- 

 surd to conclude, as some have done, that forestry consists of planting 

 a tree every time one is cut. Even if planting were the best method, 

 many more than one tree would have to be planted for each one cut,
