covered during one Rotation, and every Cutting Series on the prop- 

 erty is planned to be cut over in this same sequence and at the

 of two lots, often of a single lot, and is cut over in ten or twenty 

 years, and normally in much less than the full Rotation.

Figure 4. Reuss' Pattern of Division and Distribution of old and young 

 Stands. This separates the oldest, and the youngest better than is done in 

 Figure 3. In any case the danger line is the line between the oldest and 

 youngest stands. Schematic and conditions as they may be found at any 

 time. Only two lots in each Cutting Series ; this is optional. 



!\rayr in his Waldbau recommends going a step further and 

 making the Sub-Lot or even a smaller area the Cutting Series to 

 enable ^ better use of the land ; his idea being that each stand should 

 be pure, i. e., of one species, but that the stands should be small, and 

 diflferent kinds of these small stands mixed to produce a mixed 

 forest of pure stands.
