water with its charge of gold-dust and gravel being sent through 
a tunnel three thousand feet long, where quicksilver catches the 
gold. 
Here are sphagnum swamps encircled by alders and willows, 
and whitened with Lriophorums like our bogs at home in New 
England. 
Potentilla palustris, which we find here, is an old friend, too, 
but the snowy slopes that wall us in remind us that we are in 
Alaska. These slopes are rich in brilliant flowering plants, par- 
ticularly alpine and sub-alpine. 
As we ascend along the snowy gorge, we meet above the tree- 
_ line and the salmonberry bushes a tangle of Heracleum lanatum, 
Aquilegia formosa, A conitum, Veratrum, Senecio, Valeriana, Ge- 
ranium and Spirega Then the flowers show broad belts of color: 
here are the rose purple and white Epélobinm latifolium,; golden 
Geums and Ranunculus; blue Violas; pink Pyrola minor, white 
Polygonum viriparum, white Eriogynia pectinata with its beauti- 
ful feathery vines; heath like plants, as Cassiopfe, in pink and 
white; Bryanthus glanduliflorus, yellow-green; Silene acaulis, 
showing a rich spread of pink; Hieracium triste, with black woolly 
involucres; Anemone Richardsoni, delicate yellow; white A. nar- 
cissiflora, and parviflora veined with purple. There were Aruicas, 
too, and representatives of Saxifraga, Parnassia, Tofieldia, Gen- 
tiana, Pedicularis, Astragalus, Oxytropis, Habenaria, Stellarta, 
and Cerastium, alpine Salices in full bloom, and many more, 
covering the steep mountain-side, where the loose rocks would 
seem to leave no chance for even a plant to find foothold. From 
the top the slope presents a gorgeous stretch of color long to be 
remembered ! : 
In going to a new region the relative importance of certain 
genera hardly noticed at home comes out sharply. 
- The Saxifrages are here a dominating group, both ai to 
abundance and variety. : 
The Yiarella trifoliata is graceful and delicate; Mite/la pen- 
fandra and Telima grandiflora are sturdy, rough-leaved plants; 
Boykinia major is a plumy species, and covers the rocks with its 
white sprays. Over the bare landslides spread Saxifraga leu- 
‘anthemifolia and S. punctata; and S. bronchialis, and S oppo-
