bog. In most places water gathers at once around the foot 
in the moss, which is like a sponge soaked full of water. 
Soon the eye is attracted by the odd leaves and flowers of 
the pitcher plant (Sarracemia purpurea), most of whose 
leave-pitchers, bristle-beset, are filled with water also. When 
one comes upon a colony of large, luxuriant pitcher-plants, 
it is a sight not soon forgotten, during the spell of which, 
while gazing on, one is apt to forget all about birds. Be- 
sides sphagum the characteristic peat bog flora consists of 
such thick-leaved, glaucous bushes as Cassandra, Chamae- 
daphne calyculata, Andromeda glaucophylla, Kalmia_ pro- 
lifolia, Ledum groenlandicum, different kinds of huckle- and 
blueberries, also large and small cranberries. [lere and there 
are a number of small, stunted black spruce and tamarack 
trees, which in places form thickets, with now and then a 
patch of deciduous bushes, as Cornus, alder, viburnum, etc., 
between. In such patches are found the Canadian and Chest- 
nut-sided Warblers, also a few Maenolia and Blackburnian 
Warblers. 
But these are not the characteristic bog birds. Out in the 
open, where grow small, dwarfed spruces, with much space 
between them, we hear a song much like that of the Pine 
Warbler, or Chipping Sparow. There the bird is perching 
in a spruce. It turns out to be a Yellow Palm Warbler, 
Dendroica palmarum hypochrysea. Vhe Palm Warbler, D. 
palmarum, also occurs in the region, but apparently only as 
a migrant, and it seems as if fy pochrysca arrives here before 
palmarum, as a nest of the former, containing four eggs, 
was found as early as May 23, (1908). Here, where single 
stems of wooly-headed Eriphorum callitris stick up from the 
sphagnum, and, in August, the beautiful White-fringed 
Orchis. Habenaria- blephariglottis, is also the home of the 
White-threated Sparrow. His slow, measured song of vari- 
ous numbers of syllables can be heard on all sides. Cana- 
dians make it say, Dear, dear, Canada, Canada, Canada. 
Once, while resting from the laborious, heavy walking or 
wading under a hot sun, one struck up his tune near me, and,
