82 THE PRINCIPLES OF HANDLING WOODLANDS 



14. Seed-trees above the limit are left only where 

 there are none below the limit to answer the purpose. 



15. One or more trees of the species capable of bear- 

 ing seed should be left on the border of every opening 

 15 feet or more in width. 



16. In openings resulting from the cutting of a group 

 of trees, and 50 feet or more wide, seed-trees should be 

 located on the side toward the prevailing wind. 



17. In case an opening is on a slope, the seed-trees 

 should be located above rather than below the opening.
