50 ALPINE FLOWERS AND GARDENS 



In dealing, then, with Alpine flowers, it is neces- 

 sary to draw some line of demarcation ; but, at the

 relative — relative to that need for cutting up 

 Creation into sections which is so inevitable an 

 element in our means for obtaining even approxi- 

 mate understanding of the whole.
