A NATURALIST'S RAMBLES AMONG 

 THE CENTRAL PYRENEES. 



BY 



Me. H. MARRIAGE WALLIS. 



The Pyrenees run 250 miles east and west from the 

 Mediterranean to the Atlantic. Geologically speaking they are, 

 as we now see them, older than the Alps, much older than the 

 Himalayas, but compared with the Western Highlands they are 

 of somewhat modern elevation. 



The highest points of the chain are usually granite " massifs" 

 as the French call them, centi*es of upheaval which have lifted 

 the sandstone formations upon their shoulders as they rose. 



Long before the human period the work was done. Tertiary 

 deposits are bedded unconformably upon and against the tilted 

 secondary strata on the flanks of the range. 



Passes are few and high : the railways cross the range at 

 its extreme ends : for a hundred miles or more there is no road 

 practicable for wheels. The range is as typical a racial frontier 

 as any in Europe. A morning's walk takes one from a French 

 speaking village to one where perhaps hardly a word of French 

 is understood, and where dress, physiognomy, and habits, are 

 different from anything on the French side. Passing from 

 Gavarnie to Torla one steps back two or three centuries and 

 finds a substantially-built town with scarcely a glazed window, 

 without a hotel, a post office, a shop, or a piece of road upon 

 which a cart can travel. 



One recognises the forerunners of a southern type of flora
