which is considered uncommon in the state, or indeed in New Eng- 
land, is here abundant, but it always grows about the same distance 
from the marginal ridge. It is provokingly sterile. I have hunted 
long for fruit, but always unsuccessfully. This swamp i$ the home of 
the Dicrana; at least, there are three that make it their home, 
D. scoparium, with its variety pallidum, and in various forms, D. 
palustre and D. Bergeri. The latter is abundant, but not always easily 
distinguished from D. scoparium, though the trained eye can see points 
of difference at a glance. On the shores one may find D. undulatum, 
D. montanum, and D. Drummond. 
While speaking of Dicrana, I will mention finding D. viride. It 
was on a small stone in a roadside wall. It was only a little patch, but, 
unlike the species elsewhere, it was abundantly fruited. Dr. R. H. 
True told me he thought there was more fruit on that little clump than 
in all the herbaria in Europe. 
On the southern shore of Lake Attitash, a body of water in the 
western part of the town, is a wood of pine, extending, perhaps, a half 
mile, and on the bank, just over the water, for the whole distance, may 
be found a moss which, common enough in northern New England, is 
uncommon in Massachusetts, namely, Pogonatum alpinum. In this 
locality, Webera sessilis is very plentiful. In these pond regions there 
are deep depressions in which are pools of stagnant water. In these 
grow Button Bushes, which are covered with Dichelyma capillaceum and 
Fontinalis Lescurii, often in good fruit. In a similar locality in New 
Hampshire, just over the line, I find a very beautiful moss, with all the 
habits of D. capillaceum but clearly distinct from that species, or from 
D. pallescens or Hypnum fluitans, which it resembles. It is of a beauti- 
ful golden color, with a very long leaf, acutely serrate at the apex. 
I have referred it to D. Swartzii, though perhaps not correctly. 
A swamp which I have explored this summer for the first time has 
yielded quite richly. The first visit I made to it I found very little of 
interest in the moss line, but later I found on the edge of the bogs, 
where the ground was free from sedge, a moss suggesting Afichum 
undulatum, which on study proved to be A. crispum, sterile. In a later 
search I found a small patch oí fertile plants, which were very interest- 
ing indeed. I also found a very pretty little Hypnum in the same 
habitat, that is, on the bare side of the bogs, hugging closely the sedge 
roots, mostly sterile, but sometimes nicely fruited. This dainty little 
moss proves to be Plagiothecium latebricola.
