 much neglected adage, " All roads lead to Rome." 

 Now, in these two Swiss Rhododendrons there 

 is excellent occasion for noting two very different

 a common foe. The foe is drought — the drought

 the rapid, rocky, sun-baked, wind-swept slope. 

 Mountain circumstance, such as is affected for the 

 most part by these Rhododendrons, is the out-

 in the forming, and what there is of it but thinly 

 coats a tumbled bed of crevassed rocks and 

 boulders. Casual observation may lead visitors 

 to suppose the Swiss Alpine climate to be by 

 no means devoid of moisture and to be liable 

 at all seasons to its f?ir share of damp, all- 

 enveloping cloud and fog, and to storms of snow 

 and rain. And casual observation will be right.
