also those of the herbaceous plants, with the severity of the night’s 
frost, even in early July. 
On dry open grounds we found an abundance of Castilleia m 
viflora Bong., a fine scarlet-flowered species peculiar to the 
west, and with-it a more strictly alpine, and a yellow-flowered one, _ 
C. breviflora Gray. These two, together with plenty of that most 
_ handsome Pentstemon, P. acuminatus Dougl., were enough to con- 
` culus affinis R. Br.; and also an ‘Allium, species uncertain, for we

vert even the hte Wise barren hillsides into a paradise of beauty. 
Among the grasses and sedges of the marshy places, were quan- ` |

by these really handsome purple-flowered ones without taking one 
specimen for our herbarium. A fine ‘‘monkshood” (Aconitum 
nasutum Fisch.), its flowers in most cases dark purple, but in- 
other specimens yellowish-white, was also very conspicuous in 
wet shades; and in the edges of these wet places, grew Hedysa- 
rum boreale Nutt. and Astragalus alpinus sie both interesting 
leguminous plants not often met with. 
One crystal brooklet had its margins adorned with the large = 
yellow purple-dotted corollas of Mitimihes luteus L., while the- x 
damp ground near by was neatly carpeted with Veronica serpy 
lifolia L. These two elegant Scrophulariacez, one belonging í east-

Out again upon higher and drier land we suddenly came upon —
