activities. It was copiously established about the horse barns 

 near Park Headquarters in 1928. 



Phleum pratense L. Imported horse feed probably first 

 brought this grass. First noted in 1928. 



Dactylis glomerata L. Like the preceding, probably intro- 

 duced in imported horse feed. First noted in 1929. 



Bromus inermis Leyss. Also probably introduced in horse 

 feed. First noted in 1929. 



Spergularia rubra (L). Presl. var. perennans (Greene) 

 Robinson. There is some doubt concerning the nativity of this 

 plant. Greene holds it to be a native of Europe, while Jepson 

 maintains it to be a native of western America. At all events, 

 it became well established about Park Headquarters in 1929. 



Rumex crispus L. This is the latest newcomer to the Park. 

 A solitary plant has grown for two seasons near the office build- 

 ings at Park Headquarters. At this altitude of 6600 feet, the 

 very upper edge of the Canadian Life Zone is this latitude, it 

 does not seem to set fertile seeds and will consequently soon 

 become extinct. It was first seen in 1929. 



Agropyron repens (L.) Beauv. A few plants of this species 

 were found at the Lost Creek Ranger Station where horses had 

 been tethered the previous year. First noted in 1929. 



During 1930, an attempt to landscape the immediate vicin- 

 ity of the Lodge was made. Grass seed of several species were 

 sown. It is probable that future observations will show several 

 species of grass and weeds introduced at that time.
