LENTlBULARlyE, ETC. 4! 5 



May-June. Certain parts of the Jura and Ticino Alps. 

 Often flowers twice a year. 



La-haut, pres du ciel, au sein de 1'alpage, 

 Dans les blancs rochers du Jura vaudois, 

 Le doux Thymelee a la fleur en croix 

 Parfume et benit tout le voisinage. 



Tout le long du mont, sur 1'agreste crete, 

 La fleur incarnat chante nuit et jour 

 Sous le gai soleil sa chanson d'amour, 

 line melodie austere et discrete. 



La-haut, loin du bruit, loin des cris du monde, 

 II s'etale heureux, sous un ciel bien clair, 

 Et sa fleur suave aux couleurs de chair 

 Jette son encens partout comme une onde.
