The elevated hummocks are carpeted with dense beds of dwarf 

 cornel, gold-thread, etc., with scattered remnants of other spring 

 plants, as Clintonia, star-flower and others. In the boggy areas 

 are many sensitive, interrupted and other ferns and several species 

 of Carex. Most of the crane-flies designated under this caption 

 were swept from this hummock vegetation.
