Angora Ridge. — The western slope of this ridge was an alpine 

 meadow of equal altitude and hardly less interesting than that 

 on JMount Tallac. 



Half Moon Lake under Dick's Peak at an altitude of about 

 8000 feet proved to be an interesting place in late July. Several 

 eastern forms not found elsewhere were taken here. 



Grass Lake in the valley above Glen Alpine Springs at an 

 altitude of about 7500 feet did not yield much of interest, but 

 might have been better if visited later in the season.
