with fine specimens of Asplenium platyneuron, a little 
more than a mile west of Woodstock, that is, about 
eight miles west from Quechee, and Mr. J. G. Under- 
wood reports it within about five miles. 
Among the more common ferns we saw in the Gulf, 
were Adiantum; Dryopteris marginalis; D. Thelypteris 
and D. intermedia; Athyrium angustum (Willd.) Presl 
and possibly the variety elatius. Cystopteris bulbifera 
grew in profusion all along the lower sides of the cliffs 
and we found a few fronds of C. fragilis in the Gulf and 
also in the pastures above it. Polypodium vulgare was 
abundant in places, and we saw two of the Osmundas, 
O. regalis at the very water’s edge, with O. cinnamomea 
not far away. Up in the pasture we found not only the 
fragile bladder fern but W. ilvensis, Dicksonia punctilo- 
bula and Pteris aquilina. Along the railway just be- 
yond Dewey’s as we were going off we saw Onoclea sen- 
sibilis and O. Struthopteris. Most of these ferns are 
abundant in the district. But we doubt if in many other 
places the three rarer Woodsias can be found in so small 
a radius, and if in any other place so far south and at 
so low an elevation one can find such a station of Wood- 
sia alpina.

Recent Fern Literature 
Dr. J. H. Barnhart has published an interesting 
account of an American writer on ferns who is little 
known to most of us—William Brackenridge.!. Bracken- 
ridge’s own modesty and retiring disposition has made 
biographical material in regard to him difficult to ob- 
tain, but Dr. Barnhart has been able to put together 
a fairly complete narrative of his life.
