Nearly all the smaller streams make their way to the low- 

 lands through ravines which are often fifty feet or more in 

 depth. Their sides are usually quite steep, but afford a foothold 

 for a large number of species that love the shade, especially 

 ferns. The ravines are all particularly rich in species. Of those 

 mentioned in the following pages, Canavtui's Glen is west of 

 Susquehanna; Pope's ravine, northeast of Binghamton; Glen- 

 wood ravine, northwest of Binghamton, and Roert'cke's Gle?i, 

 two miles above Elmira.
