 West Hill north of State St., has been fairly well stud-

 has consisted most largely of the exploration of ravines 

 for Dentaria . Most of the species known to occur in

 knowledge of the distribution of most of the species. 



The east lake slope, from Fall Creek to Myers 

 Point, including Shurger's Glen, has been fairly well 

 covered, as have been the Six Mile Creek valley as far 

 as the Middle Reservoir, the Oascadilla Creek valley aboibt
