particular places by the artificial introduction of attractive plants from 
- other regions. But most efforts of this kind have been sporadic, short- 
lived, and relatively futile. The nice adjustment which exists in every 
native vegetation as the result of long competition and jostling of its 
components can rarely be disturbed to advantage by human agency. 
If a new plant is introduced one of three not easily predicted results is 
sure to ensue. The species may find congenial conditions, withstand 
the competition of the native plants, and quickly increase so that it be-

indigenous vegetation. On the other hand it may, and usually does,
