densis) : Found sparingly all along the route. High-bush 

 Cranberry (Viburnum pauciflorum) : Quite abundant in many 

 localities; in full bloom about July 1. Wild Rose (Rosa acicu- 

 laris) : Very common, particularly on comparatively dry ground 

 near the edge of spruce woods; blooming profusely early in 

 July. Arctic Sagebrush (Artemisia frigida) : Abundant on 

 dry sandy hillsides with southern exposure, where it grows to 

 the exclusion of almost all other plants. Labrador Tea 

 (Ledum) : Rampant in suitable places, always so in semi- 

 tundra, and very conspicuous on account of its striking starry 

 white flowers. Dwarf Laurel (Kahnia glauca) : Abundant in 

 swamps. Andromeda (Andromeda) : Occasionally found in 

 swamps in great abundance. Bear Berry (Arctostaphylos 

 uvaursi) : Fairly common, but much scattered. 



The trees, shrubs, and general plant life are much the same as 

 throughout the Hudsonian and Arctic-Alpine zones elsewhere 

 in the northwest. Among those worthy of mention are the fol- 

 lowing: 



Picea canadensis (White Spruce). — The most abundant coni- 

 fer; occurs in scattered clumps near timberline and in more or 

 less continuous forest on the lower slopes of the mountain and 

 on comparatively dry ground lower down. The trees along 

 Mission Creek are not very large, being about eight inches in 

 diameter and from thirty to fifty feet high. A few groves of 

 larger ones were seen on Comet Creek, some being eighteen 

 inches or more in diameter and about sixty feet high. 



Picea mariana (Black Spruce). — Common in moist places on 

 high exposed ridges and saddles, as well as in swampy flats 

 lower down. 



Popidus tremuloides (Aspen). — Common on dry knolls and 

 low ridges near Eagle and scattering along Mission and 

 Seward creeks. 



Populus balsamifera (Balsam Poplar). — Common, probably 

 more so than P. tremuloides. In many places along Mission 

 Creek it stands in large groves, many trees of which are sixty 

 to seventy feet high. It is cut for fuel in considerable quanti- 

 ties wherever easily accessible, being preferrd to the other tim- 

 ber of the region. 



Salix (Willow). — Several undetermined species of willow 

 occur along the streams. The following two species grow
