It is always a pleasure to come across the bell-like flowers 

 of the Cassiope, or White Heather, as it is sometimes called, 

 for aside from its own charm, it is ever a good omen of 

 charming places. It grows only along ridges and rocky 

 ledges near timber-line where everything is clean and invit- 

 ing. The peculiar, thick leaves, closely set and overlapping 

 each other, completely clothe the tough, perennial stems, 

 which freely branch below to form tangled beds, often of con- 

 siderable extent.
