{77) 



A few more firs are located between the path and road on the 

 west side of this Section. Proceeding south along the path and 

 beginning opposite the corner of the Section we have just com- 

 pleted, the first two evergreens with a yellow birch between them 

 are Nikko Firs. 



The next three beyond the intervening white poplar are Veitch 

 Firs. Farther south after an open space is a Cilician Fir. All 

 the other trees on this narrow strip between path and road we 

 shall consider later, for they belong to another genus, the Douglas 

 Fir. 



Section 2 



Section 2 of the Firs consists of two small separated areas on 

 the west side of the two roads that separate them from Section 1 

 (Map p. 57). The first little area is on the north side of the 

 Power House and in the depression partially surrounded by the 

 bank that borders the walk. There are two small firs in the 

 depression. They are 



Abies lasiocarpa, the Alpine Fir 



This species is native at high altitudes from Alaska south to 

 Oregon and Colorado. Under optimum conditions it may attain 

 a height of 160 feet, but at the upper limits of its range it is 

 generally stunted and dwarfed. It is exceedingly hardy and can 

 endure temperature conditions ranging from 90° above to 40° 

 below zero. This is one of the few firs having leaves with white 

 lines on both sides. Furthermore, the buds are completely cov- 

 ered with resin, the branchlets are pubescent and the needles are 

 directed upward and forward. It is not a satisfactory tree in the 

 Eastern States. 



Now we must go south again, this time along the western side 

 of the road and almost as far as the Elevated Station, passing the 

 collection of hemlocks on our right. Two big sugar maples stand 

 on the inside of the path just before we get to the elevated 

 approach and west of them we see the last of the firs.
