Tuur in the Eiujadinc. 77 



sprang from rock to rock along the face of the precipice, 

 passing only a few yards from us. This piece of good luck, 

 as well as the botanical treasures we had found, encouraged 

 us to continue our difficult descent. With a good deal of 

 trouble we at last reached a steep slope of snow, down which 

 we glissaded, and, crossing the glacier witliout adventure, 

 descended a second cliff into the Bevers Valley. 



Here we found Gentiana punctata, large quantities of 

 which had been cut down by the peasants, probably with a 

 view to its use in Materia Medica. In one rocky gully 

 Pcdicularis atro-j)urpurca was expanding luxuriantly its 

 fern-like foliage. Further down, a great variety of Aconites, 

 blue, variegated, and yellow, were growing along with 

 Senecio sarmcenicus, and many other plants. After a long- 

 walk we returned to Pontresina. 



Another excursion which proved botanically interesting, 

 was that to the Val del Fain (or Hay Valley), which opens 

 into the Bernina Valley, not far from the pass. The moun- 

 tains on both sides of this valley consist of limestone. 

 Here we found Liliam Martagon, Aquilcgicc alpina, Gentiana 

 lutea, Campanula thyrsoidca, Helianthernum vidgarc and 

 celandicum, Sempervivum arachnoidcum, Widfeni and (I 

 think) Broivnii, Gnaphcdium leontopodium (the celebrated 

 Edelweiss), Senecio ah^otanifolius, Aronicum scoipioides, 

 Ranunculus montanus, Papaver alpinuvi, Fliytcuma huinile, 

 with several cruciferous, leguminous, and other plants. 



Our return journey was made from the Engadine to iJavos 

 by the Scaletta Pass, and from Davos to Chur by the Strela ; 

 both these passes are crossed only by footpaths. Our dried 

 specimens were sent round by coach; those in process of 

 drying we carried with us. We found very frequent changes 

 of paper the best means of preserving the natural colours 

 of the plants. We had particular difficulty with Dry as 

 oetopetula, but at last succeeded in inducing one specimen 

 to remain white, the campanulas were obstinate to the last.
