down at the moistest pool edge are Nephrodium 

 Thelypteris and Lomaria, and a little way up on the 

 cool bank, always in shade, the North American 

 Onoclea sensibilis. In a moist nook already filled with 

 Sphagnum, in this region of Fern beauty, and with

 spikes of leaf and bloom. 



Such a sight seems to give the mind a kind of full
