HANNIBAL: A PLIOCENE FLORA FROM CALIFORNIA 335 
Range. Mr. John Hain, an old resident of Bear Valley, interested 
in natural history, pointed out this locality to Dr. C. H. Gilbert 
a number of years ago. It was subsequently visited by Dr. 
Smith, Mr. Fordyce Grinnell, Jr., and the writer in 1907, and by 
the writer in 1910. The main exposure apparently represented 
an old tule bed, consisting of an interlacing mass of indeterminate 
carbonized stems in peaty clay. Farther up the same branch 
of the gully a few fairly well preserved leaves were obtained.
