in the ridge, a circular area was seen two rods in diameter, from 

 which the snow was melted, apparently by spring water. The 

 whole circle was thickly covered by the white blossoms which 

 crowded closely to the snow wall, seven feet high, which in- 

 closed the area. 



"We have before mentioned the finding of a specimen of 

 Trillium ovatum, forcing its blossom and leaves through three 

 inches of granulated snow. The plant was abundant on the west 

 side of the mountain. 



"Some plants familiar in the East were found remarkably 

 dwarfed by the cold. The Claytonia caroliniana [apparently C. 

 lanceolata Pursh.; represented by a single fragmentary speci- 

 men] was found at an altitude of six thousand feet, not more 

 than an inch high, yet in full bloom. It covered the ground 

 thickly under a tree. A Ranunculus [immature] was found in 

 the margin of Lake Templin, altitude five thousand feet. Dr. 

 Gray expressed the opinion that it was R. rhomboideus dwarfed 

 by the cold. The length of the specimen is about an inch. The 

 yellow blossoms covered the water thickly. Dr. Vasey dissented 

 from the opinion that it was R. rhomboideus. 



"Only one plant of the Xerophyllum tenax was found in 

 blossom. This was at an altitude of four thousand feet, on the 

 west side of the mountain, June 26. The plants were common at 

 the highest altitudes. 3 



"The Lewisia rediviva, the 'Bitter Root,' which gives name 

 to the mountains, and also to the river and valley which the 

 missionaries named St. Mary's, was found at the Hot Springs, 

 July 6. This plant became known through the collection of 

 Lewis and Clarke, who passed this locality at the time of its 

 blossoming in 1806. 



"In riding over the snow at midday, July 3, at an altitude of 

 six thousand feet, the horses' feet sank into the melting snow 

 to the fetlock. Suddenly it was noticed that all of the tracks of 

 the horses, over quite a large area, appeared red as if stained 

 with blood. Collecting some of the snow and applying the lens, 

 the little grains of the Protococcus nivalis were clearly seen float- 



3 Apparently 1866 was not a beargrass year. This very showy member of 

 the Lily family with its dense, club-shaped raceme of white flowers seems to 

 bloom profusely only at intervals, variously estimated at from three to seven 

 years.— W.T.M.
